For example, the TLR7 stimulant imiquimod is used for the treatment of skin cancer and metastatic melanoma. However, new research, performed by Isabelle Cremer and colleagues, at INSERM U872, Paris, suggests that such approaches should be developed with caution because stimulation of human lung cancer cells with TLR7 or TLR8 agonists increased tumor cell survival and resistance to chemotherapeutics...

Our results reveal a significant correlation of miR-10b level with cell motility and invasiveness. Overexpression of miR-10b in KYSE140 cells increased cell motility and invasiveness, whereas inhibition of miR-10b in EC9706 cells reduced cell invasiveness, although it did not alter cell motility. Additionally, we identified KLF4, a known tumor suppressor gene that has been reported to suppress esophageal cancer cell migration and invasion, as a direct target of miR-10b. Furthermore, overexpression of miR-10b in KYSE140 and KYSE450 cells led to a reduction of endogenous KLF4 protein, whereas silencing of miR-10b in EC9706 cells caused up-reg...

Mutations in XPF are linked to xeroderma pigmentosum, characterized by sun sensitivity, high incidence of skin cancer, and neurodegeneration, or XFE progeroid syndrome, a disease of accelerated aging. Herein we report the unexpected finding that mutations in XPF cause mislocalization of XPF-ERCC1 to the cytoplasm. Recombinant mutant XPF-ERCC1 derived from XP? and XFE?causing alleles are catalytically active and if delivered to the nucleus of cells restore DNA repair. This demonstrates that protein mislocalization contributes to defective DNA repair and disease arising as a consequence of mutations in XPF. It also illustrates a novel mechanism of regulating a cell's capacity for DNA repair: by manipulating... Autosomal dominant polycystic kidney disease: risk factor for nonmelanoma skin cancer following kidney transplantation Nonmelanoma skin cancers (NMSC) are the most common malignant tumors following solid organ transplantation. Risk factors for NMSC mainly include immunosuppression, age, sun exposure and patient phototype. Recent findings have suggested that autosomal dominant polycystic kidney disease (ADPKD) may increase the risk of developing NMSC. We performed a monocenter retrospective study including all kidney recipients between 1985 and 2006 (n = 1019). We studied the incidence of NMSC, solid cancers and post-transplantation lymphoproliferative disease (PTLD), and analyzed the following parameters: age, gender, phototype, time on dialysis, graft rank, immunosuppressive regimen, history of cancer and kidney disease (ADPKD versus others).

Authors: Hijioka H, Setoguchi T, Miyawaki A, Gao H, Ishida T, Komiya S, Nakamura N The constitutive activation of the Notch pathway has been demonstrated in various types of malignancies. However, it remains unclear how the Notch pathway is involved in the pathogenesis of oral squamous cell carcinoma (OSCC). We investigated the expression of Notch pathway molecules in OSCC cell lines and biopsy specimens and examined the effect of Notch pathway inhibition. Reverse transcription-polymerase chain reaction revealed upregulation of Notch1, Notch2, Jagged1, HES1 and HEY1 in both OSCC cell lines and biopsy specimens. Immunohistochemical examination showed that the Notch intracellular domain accumulates in the nucleus of cells in OSCC cell lines and biopsy specimens. In addition, Jagged1 is e... Development of an oral cancer recurrence mouse model after surgical resection. Authors: Behren A, Kamenisch Y, Muehlen S, Flechtenmacher C, Haberkorn U, Hilber H, Myers JN, Bergmann Z, Plinkert PK, Simon C Oral squamous cell carcinomas (OSCC) are frequent epithelial malignancies and afflicted with a poor prognosis. The majority of these cancers are treated with surgical resection and local recurrences are predominantly responsible for a fatal outcome. In order to provide a better understanding of the development of these local recurrences after surgical ablation, we developed an orthotopic floor-of-mouth squamous cell carcinoma murine model, in which local recurrences occur at a high frequency (55%, 8 out of 15 mice) within 6-21 days after microsurgical removal of the primary.

In the present study, we investigated the effects of PLK1 and HSF1 knockdown on the proliferation of oral cancer cells using small interfering RNA. In human oral squamous cell carcinoma (SCC) tissues, the levels of PLK1 and HSF1 were higher compared to normal tissues. The expression levels of PLK1 and HSF1 were also elevated in the human oral SCC cell lines FaDu and HEp-2. Disruption of PLK1 induced cell cycle arrest at G2/M phase as well as apoptosis in oral cancer cells. Interestingly, knockdown of both PLK1 and HSF1 expression decreased cell proliferation while increasing apoptotic cell death in synergistic fashion.

However, HIF target genes in the esophageal tumor microenvironment remain elusive. Gene expression profiling was performed upon hypoxia-exposed non-transformed immortalized human esophageal epithelial cells, EPC2-hTERT, and comparing with a gene signature of esophageal squamous cell carcinoma (ESCC). In addition to known HIF-1 target genes such as carbonic anhydrase 9, insulin-like growth factor binding protein-3 (IGFBP3) and cyclooxygenase (COX)-2, prostaglandin E synthase (PTGES) was identified as a novel target gene among the commonly upregulated genes in ESCC as well as the cells exposed to hypoxia. The PTGES induction was augmented upon stabilization of HIF-1 by hypoxia or cobalt chloride und... The Bmi-1 polycomb protein antagonizes the (-)-epigallocatechin-3-gallate-dependent suppression of skin cancer cell survival The polycomb group (PcG) proteins are epigenetic regulators of gene expression that enhance cell survival. This regulation is achieved via action of two multiprotein PcG complexes—PRC2 (EED) and PRC1 [B-cell-specific Moloney murine leukemia virus integration site 1 (Bmi-1)]. These complexes modulate gene expression by increasing histone methylation and reducing acetylation—leading to a closed chromatin conformation. Activity of these proteins is associated with increased cell proliferation and survival. We show increased expression of key PcG proteins in immortalized keratinocytes and skin cancer cell lines.

Cutaneous pigmentation, particularly eumelanin, afforded by melanocytes is the main photoprotective mechanism, as it prevents UV-induced DNA damage in the epidermis. Therefore, maintaining genomic stability of melanocytes is crucial for prevention of melanoma, as well as keratinocyte-derived basal and squamous cell carcinoma. A critical independent factor for preventing melanoma is DNA repair capacity.

Authors: Piergiacomo CP, Mariachiara A, Sereni E, Bernhard O Photodynamic therapy (PDT) with methylaminolevulinate (MAL) has demonstrated high efficacy, minimal side effects, and improved cosmetic outcome in the treatment of its EU-approved clinical indications, i.e. actinic keratoses (AKs), basal cell carcinoma, and Bowen's disease. In addition, PDT with MAL or 5-aminolevulinic acid (ALA) is approved in the US for the treatment of AK. However, besides anti-tumoral activity, PDT has also demonstrated various anti-inflammatory and anti-infectious effects as well as those on the metabolism of connective tissue, keratinization of normal keratinocytes and maturation processes of sebaceous glands and hair follicles. These findings have expanded the spectrum of possible applications of PDT t... Treatment with IFN-{alpha}, -{beta}, or -{gamma} Is Associated with Collapsing Focal Segmental Glomerulosclerosis.

Pragmatics versus contrarians: how does one resolve their differences with respect to oral cancer screening? With an annual incidence of nearly 600,000 cases, oral and pharyngeal squamous cell carcinoma is the sixth most common malignancy in the world today.

When focusing specifically on the oral cavity, it is estimated there will be over 23,000 new cases and more than 5,300 deaths. Despite advances in therapy, long-term survival for patients with oral cavity cancers has remained largely unchanged. Several factors contribute to this poor outcome.

Authors: Dilillo DJ, Yanaba K, Tedder TF B lymphocytes can both positively and negatively regulate cellular immune responses. Previous studies have demonstrated augmented T cell-mediated tumor immunity in genetically B cell-deficient mice, suggesting that therapeutic B cell depletion would enhance tumor immunity. To test this hypothesis and quantify B cell contributions to T cell-mediated anti-tumor immune responses, mature B cells were depleted from wild-type adult mice using CD20 mAb prior to syngeneic B16 melanoma tumor transfers. Remarkably, s.c. tumor volume and lung metastasis were increased 2-fold in B cell-depleted mice. Effector-memory and IFN-gamma-or TNF-alpha-secreting CD4(+) and CD8(+) T cell induction was significantly impaired in B cell-depleted mice with tumors. Tumor A... Blockade of Programmed Death Ligand 1 Enhances the Therapeutic Efficacy of Combination Immunotherapy against Melanoma.

We have used positively charged liposomes composed of phosphatidylcholine (PC), dioleoylphosphatidylethanolamine (DOPE), cholesterol (Chol) and stearylamine (SA) (6:1:2:1 M ratio) as a carrier system for bovine iron-free Lf (ApoBLf), and compared the in vitro effect of free and liposome-entrapped ApoBLf on the growth and morphology of murine melanoma B16-F10 cells.

(Source: Ophthalmology) p38 Regulates Pigmentation via Proteasomal Degradation of Tyrosinase [Signal Transduction] The synthesis of melanin pigments, or melanogenesis, is regulated by the balance of a variety of signal transduction pathways. Among these pathways, p38 MAPK signaling was found to be involved in stress-induced melanogenesis and to be activated by -melanocyte-stimulating hormone (-MSH) and ultraviolet irradiation. Previous studies have shown that -MSH-stimulated melanogenesis can be inhibited by blocking p38 MAPK activity with SB203580, a pyridinyl imidazole compound. Consistent with this, we observed that pyridinyl imidazoles (SB203580 and SB202190) inhibited both basal and -MSH-induced melanogenesis in B16 melanoma cells. However, SB202474, which has no ability to inhibit p38 MAPK activity and is usually used as a negative control compound in p38 MAPK studies, also suppressed melanin syn...

Decreased nuclear expression and increased cytoplasmic expression of ING5 may be linked to tumorigenesis and progression in human head and neck squamous cell carcinoma Conclusions  Our results suggest that a decrease in nuclear ING5 localization and cytoplasmic translocation are involved in tumorigenesis and tumor differentiation in HNSCC. Nuclear ING5 may modulate the transactivation of target genes, and may promote apoptosis and cell cycle arrest by interacting with the p300 and p21 proteins. ING5 may function as a tumor suppressor gene or oncogene tightly linked with p53 status, and may play an important role in the prognosis of HNSCC patients. Therefore, we propose that ING5 represents a novel potential molecular therapeutic target for HNSCC.

Could Exercise Really Help To Protect Against Skin Cancer?

Could Exercise Really Help To Protect Against Skin Cancer?
By Louise Forrest

The benefits of exercise to the skin have become more and more
apparent over the past couple of years. It has been established
that exercise provides great benefits in ways there were not
ever thought of. When combined with a healthy diet, regular
exercise can dramatically help to produce healthy, glowing skin.

However, not only can exercise help with a glowing complexion,
it has also been proven to dramatically cut the risk of skin
cancer. With being such a massive threat these days,
anything that can seriously cut the risk of developing it is
definitely a positive thing!

Exercise and Skin Cancer:
The tests that were done to prove the link between exercise and
skin cancer, were carried out on mice. It was shown that mice
who had exercise wheels, and who were exposed to ultra violet
light, had a reduced chance of developing tumours than those who
did not have a wheel. This does not mean that they did not
develop the cancer; it just took longer exposure for them to
actually get it.

It is thought that the results are the same with humans, only
obviously we wear sunscreen to protect ourselves so we have even
less risk of developing the cancer if we exercise and protect
ourselves. It is thought that the less fat we have in our body,
the less chance we have of developing the cancer.

Although the tests have shown that the mice fought off the
cancer for longer, scientists have yet to discover what it is
exactly that helps fight it. It seems that the mice were able to
destroy the skin cells which had been damaged by the sun's UV
rays once they had undertaken regular exercise, and now the
challenge the scientists face, is finding out exactly what it is
that helps fight the effects of the rays.

It is obviously better for the body all around if you keep it
fit and healthy. Being overweight can really put a real strain
on the body, and you are generally more likely to be unhealthy
if you are overweight, than if you were the right weight for
your height.

Dermatologists can diagnose and treat early stage melanomas using new technology
According to estimates from the American Cancer Society, melanoma, the most serious form of skin cancer, was responsible for an estimated 8,650 deaths in the United States in 2009. Of growing concern among dermatologists is the fact that melanoma is now the most common form of cancer for young adults 25-29 years old and the second most common cancer in adolescents and young adults 15-29 years old. Early diagnosis is the key to curing this potentially deadly disease, and diagnostic tools are playing a crucial role in aiding dermatologists to spot melanomas at earlier -- and more curable -- stages.

MicroRNA-10b Promotes Migration and Invasion through KLF4 in Human Esophageal Cancer Cell Lines [Gene Regulation]
In this study, we have analyzed the level of miR-10b and cell motility and invasiveness in several human esophageal squamous cell carcinoma cell lines. Our results reveal a significant correlation of miR-10b level with cell motility and invasiveness. Overexpression of miR-10b in KYSE140 cells increased cell motility and invasiveness, whereas inhibition of miR-10b in EC9706 cells reduced cell invasiveness, although it did not alter cell motility. Additionally, we identified KLF4, a known tumor suppressor gene that has been reported to suppress esophageal cancer cell migration and invasion, as a direct target of miR-10b. Furthermore, overexpression of miR-10b in KYSE140 and KYSE450 cells led to a reduction of endogenous KLF4 protein, whereas silencing of miR-10b in EC9706 cells caused up-reg...

Mislocalization of XPF-ERCC1 Nuclease Contributes to Reduced DNA Repair in XP-F Patients
Author Summary XPF-ERCC1 is a nuclease that plays a critical role in DNA repair. Mutations in XPF are linked to xeroderma pigmentosum, characterized by sun sensitivity, high incidence of skin cancer, and neurodegeneration, or XFE progeroid syndrome, a disease of accelerated aging. Herein we report the unexpected finding that mutations in XPF cause mislocalization of XPF-ERCC1 to the cytoplasm. Recombinant mutant XPF-ERCC1 derived from XP? and XFE?causing alleles are catalytically active and if delivered to the nucleus of cells restore DNA repair. This demonstrates that protein mislocalization contributes to defective DNA repair and disease arising as a consequence of mutations in XPF. It also illustrates a novel mechanism of regulating a cell's capacity for DNA repair: by manipulating...
Autosomal dominant polycystic kidney disease: risk factor for nonmelanoma skin cancer following kidney transplantation
Nonmelanoma skin cancers (NMSC) are the most common malignant tumors following solid organ transplantation. Risk factors for NMSC mainly include immunosuppression, age, sun exposure and patient phototype. Recent findings have suggested that autosomal dominant polycystic kidney disease (ADPKD) may increase the risk of developing NMSC. We performed a monocenter retrospective study including all kidney recipients between 1985 and 2006 (n = 1019). We studied the incidence of NMSC, solid cancers and post-transplantation lymphoproliferative disease (PTLD), and analyzed the following parameters: age, gender, phototype, time on dialysis, graft rank, immunosuppressive regimen, history of cancer and kidney disease (ADPKD versus others). Median follow-up was 5.5 years (range: 0.02[ndash]20.6; 79 838 ...

Intratumoral forkhead box P3-positive regulatory T cells predict poor survival in cyclooxygenase-2-positive uveal melanoma
The objective of the current study was to investigate whether Tregs infiltrate uveal melanomas (UMs) and whether their prevalence is linked to COX-2 expression and the prediction of overall survival (OS).One hundred patients who underwent enucleation after they were diagnosed with UM were included in the study. Immunohistochemical staining with monoclonal anti-FOXP3, anti-CD4, and anti-COX-2 antibodies was performed, and immunoreactivity was assessed. Correlations of COX-2 expression with the presence of Tregs, established clinicopathologic parameters, and OS were evaluated in univariate and multivariate analyses.High expression of COX-2 was predictive of shortened OS. FOXP3-positive Tregs were detectable in 24% of UMs and were restricted to malignant tissue.

Upregulation of Notch pathway molecules in oral squamous cell carcinoma.
Authors: Hijioka H, Setoguchi T, Miyawaki A, Gao H, Ishida T, Komiya S, Nakamura N The constitutive activation of the Notch pathway has been demonstrated in various types of malignancies. However, it remains unclear how the Notch pathway is involved in the pathogenesis of oral squamous cell carcinoma (OSCC). We investigated the expression of Notch pathway molecules in OSCC cell lines and biopsy specimens and examined the effect of Notch pathway inhibition. Reverse transcription-polymerase chain reaction revealed upregulation of Notch1, Notch2, Jagged1, HES1 and HEY1 in both OSCC cell lines and biopsy specimens. Immunohistochemical examination showed that the Notch intracellular domain accumulates in the nucleus of cells in OSCC cell lines and biopsy specimens. In addition, Jagged1 is e...
Development of an oral cancer recurrence mouse model after surgical resection.
Authors: Behren A, Kamenisch Y, Muehlen S, Flechtenmacher C, Haberkorn U, Hilber H, Myers JN, Bergmann Z, Plinkert PK, Simon C Oral squamous cell carcinomas (OSCC) are frequent epithelial malignancies and afflicted with a poor prognosis. The majority of these cancers are treated with surgical resection and local recurrences are predominantly responsible for a fatal outcome. In order to provide a better understanding of the development of these local recurrences after surgical ablation, we developed an orthotopic floor-of-mouth squamous cell carcinoma murine model, in which local recurrences occur at a high frequency (55%, 8 out of 15 mice) within 6-21 days after microsurgical removal of the primary. Expression of the enhanced green fluorescent protein (eGFP) in the cancer cells allows ...
The antitumor effect of PLK1 and HSF1 double knockdown on human oral carcinoma cells.
Authors: Kim SA, Kwon SM, Yoon JH, Ahn SG High levels of mitotic progression-associated PLK1 and stress-associated HSF1 have been observed in various human cancers. In the present study, we investigated the effects of PLK1 and HSF1 knockdown on the proliferation of oral cancer cells using small interfering RNA. In human oral squamous cell carcinoma (SCC) tissues, the levels of PLK1 and HSF1 were higher compared to normal tissues. The expression levels of PLK1 and HSF1 were also elevated in the human oral SCC cell lines FaDu and HEp-2. Disruption of PLK1 induced cell cycle arrest at G2/M phase as well as apoptosis in oral cancer cells. Interestingly, knockdown of both PLK1 and HSF1 expression decreased cell proliferation while increasing apoptotic cell death in synergistic fashion.

Hypoxia activates the cyclooxygenase-2-prostaglandin E synthase axis
Hypoxia-inducible factors (HIFs), in particular HIF-1, have been implicated in tumor biology. However, HIF target genes in the esophageal tumor microenvironment remain elusive. Gene expression profiling was performed upon hypoxia-exposed non-transformed immortalized human esophageal epithelial cells, EPC2-hTERT, and comparing with a gene signature of esophageal squamous cell carcinoma (ESCC). In addition to known HIF-1 target genes such as carbonic anhydrase 9, insulin-like growth factor binding protein-3 (IGFBP3) and cyclooxygenase (COX)-2, prostaglandin E synthase (PTGES) was identified as a novel target gene among the commonly upregulated genes in ESCC as well as the cells exposed to hypoxia. The PTGES induction was augmented upon stabilization of HIF-1 by hypoxia or cobalt chloride und...
The Bmi-1 polycomb protein antagonizes the (-)-epigallocatechin-3-gallate-dependent suppression of skin cancer cell survival
The polycomb group (PcG) proteins are epigenetic regulators of gene expression that enhance cell survival. This regulation is achieved via action of two multiprotein PcG complexes—PRC2 (EED) and PRC1 [B-cell-specific Moloney murine leukemia virus integration site 1 (Bmi-1)]. These complexes modulate gene expression by increasing histone methylation and reducing acetylation—leading to a closed chromatin conformation. Activity of these proteins is associated with increased cell proliferation and survival. We show increased expression of key PcG proteins in immortalized keratinocytes and skin cancer cell lines. We examine the role of two key PcG proteins, Bmi-1 and enhancer of zeste homolog 2 (Ezh2), and the impact of the active agent in green tea, (–)-epigallocatechin-3-gal...

Stepping up melanocytes to the challenge of UV exposure
Exposure to solar ultraviolet radiation (UV) is the main etiological factor for skin cancer, including melanoma. Cutaneous pigmentation, particularly eumelanin, afforded by melanocytes is the main photoprotective mechanism, as it prevents UV-induced DNA damage in the epidermis. Therefore, maintaining genomic stability of melanocytes is crucial for prevention of melanoma, as well as keratinocyte-derived basal and squamous cell carcinoma. A critical independent factor for preventing melanoma is DNA repair capacity. The response of melanocytes to UV is mediated mainly by a network of paracrine factors that not only activate melanogenesis, but also DNA repair, anti-oxidant, and survival pathways that are pivotal for maintenance of genomic stability and prevention of malignant transformation or...
A Critical Reappraisal of Off-Label Indications for Topical Photodynamic Therapy with Aminolevulinic Acid and Methylaminolevulinate.
Authors: Piergiacomo CP, Mariachiara A, Sereni E, Bernhard O Photodynamic therapy (PDT) with methylaminolevulinate (MAL) has demonstrated high efficacy, minimal side effects, and improved cosmetic outcome in the treatment of its EU-approved clinical indications, i.e. actinic keratoses (AKs), basal cell carcinoma, and Bowen's disease. In addition, PDT with MAL or 5-aminolevulinic acid (ALA) is approved in the US for the treatment of AK. However, besides anti-tumoral activity, PDT has also demonstrated various anti-inflammatory and anti-infectious effects as well as those on the metabolism of connective tissue, keratinization of normal keratinocytes and maturation processes of sebaceous glands and hair follicles. These findings have expanded the spectrum of possible applications of PDT t...

Oral Cavity Squamous Cell Carcinoma and the Clinically N0 Neck: The Past, Present, and Future of Sentinel Lymph Node Biopsy
Abstract  Oral cavity squamous cell carcinoma (OCSCC) has a yearly incidence of 274,000 patients. Twenty percent to 30% of patients will harbor occult regional metastases, an important feature that correlates with worse outcomes. Supraomohyoid neck dissection (SND) is the gold standard treatment, but because of recent successes of sentinel lymph node (SLN) biopsy in the management of breast cancer and melanoma, many have begun evaluating its use in head and neck mucosal cancers. SLN biopsy offers patients decreased morbidity compared with SND, and has shown reproducibly low false-negative rates, high-negative predictive values, and high sensitivities. Limitations with floor-of-mouth primaries and delayed secondary SNDs have been described, but a new agent designed to addres...<div id="medworm"><p><b><i>MedWorm Message:</i></b> Get the very latest Swine Flu news via the MedWorm <b><a href="http://www.medworm.com/rss/search.php?qu=%2Bswine+%2B%28influenza+flu%29&t=Swine+Flu&f=infectiousdiseases&r=Any&o=d" target ="_self">Swine Flu RSS news feed</a></b> - updated hourly from thousands of authoritative health and news sources.</p></div>
Relevance of serum estradiol and estrogen receptor beta expression from a high-incidence area for esophageal squamous cell carcinoma in China
This study indicates that lower serum level of estradiol may represent higher predisposition for development of ESCC, and ER? expression and/or nuclear location may predict better outcome for patients with ESCC. The present results provide clues to explain the striking gender difference for ESCC, which warrants further investigations on potential applications of estrogen or analogs in prevention of ESCC.

3-Phosphoinositide-Dependent Protein Kinase-1 Regulates Proliferation and Survival of Cancer Cells with an Activated Mitogen-Activated Protein Kinase Pathway.
In this study, we show that the reduction of PDK1 by RNAi in melanoma and colon cancer cell lines activated in the MAPK pathway results in significant cell growth inhibition and apoptosis. Furthermore, PDK1 reduction in tumor cells resulted in impaired PAK kinase signaling, altered actin polymerization, and reduced cell migration. These studies show that PDK1 plays a pivotal role in MAPK and PI3K signaling in tumor cells. Mol Cancer Res; 8(3); 421-32. PMID: 20197379 [PubMed - as supplied by publisher] (Source: Cell Research)
Prevalence of BRCA2 and CDKN2a mutations in German familial pancreatic cancer families
Abstract  Previous small scale studies reported that deleterious BRCA2 and CDKN2a germline mutations contribute to a subset of families with inherited pancreatic cancer. As the prevalence of those mutations in the setting of familial pancreatic cancer is still not well defined for the German population, we evaluated the presence of BRCA2 and CDKN2a germline mutations in a large cohort of familial pancreatic cancer (FPC) families from the German National Case Collection for Familial Pancreatic Cancer (FaPaCa). Fifty-six FPC families with at least two-first-degree relatives with confirmed pancreatic cancer that did not fulfill the criteria of other tumor predisposition syndromes, were analyzed for BRCA2 and CDKN2a germline mutations by DHPLC and/or direct sequencing.

PAI-1 Regulates the Invasive Phenotype in Human Cutaneous Squamous Cell Carcinoma
The emergence of highly aggressive subtypes of human cutaneous squamous cell carcinoma (SCC) often reflects increased autocrine/paracrine TGF-β synthesis and epidermal growth factor receptor (EGFR) amplification. Cooperative TGF-β/EGFR signaling promotes cell migration and induces expression of both proteases and protease inhibitors that regulate stromal remodeling resulting in the acquisition of an invasive phenotype. In one physiologically relevant model of human cutaneous SCC progression, TGF-β1+EGF stimulation increases the production of several matrix metalloproteinases (MMPs), among the most prominent of which is MMP-10—an MMP known to be elevated in SCC in situ. Activation of stromal plasminogen appears to be critical in triggering downstream MMP activit...<div id="medworm"><p><b><i>MedWorm Message:</i></b> Get the very latest Swine Flu news via the MedWorm <b><a href="http://www.medworm.com/rss/search.php?qu=%2Bswine+%2B%28influenza+flu%29&t=Swine+Flu&f=infectiousdiseases&r=Any&o=d" target ="_self">Swine Flu RSS news feed</a></b> - updated hourly from thousands of authoritative health and news sources.</p></div>

Tumors exposed to acute cyclic hypoxic stress show enhanced angiogenesis, perfusion and metastatic dissemination
Clinical studies have shown that patients with highly hypoxic primary tumors may have poor disease-free and overall survival rates. Studies of experimental tumors have revealed that acutely hypoxic cells may be more metastatic than normoxic or chronically hypoxic cells. In the present work, causal relations between acute cyclic hypoxia and metastasis were studied by periodically exposing BALB/c nu/nu mice bearing A-07 human melanoma xenografts to a low oxygen atmosphere. The hypoxia treatment consisted of 12 cycles of 10 min of 8% O2 in N2 followed by 10 min of air for a total of 4 hr, began on the first day after tumor cell inoculation and was given daily until the tumors reached a volume of 100 mm3. Twenty-four hours after the last hypoxia exposure, the primary tumors were subjected to d...

Overexpression of the novel human gene, UBE2Q2, in breast cancer
Abstract: The ubiquitin?proteasome pathway facilitates the degradation of damaged proteins and regulates growth and stress response. This pathway is activated in various cancers, including breast cancer. We have previously reported that the novel human gene, UBE2Q2, is a putative ubiquitin-conjugating enzyme that is located on chromosome 15 and is overexpressed in tumor mass and invasive epithelium in head and neck squamous-cell carcinoma. Here, real-time polymerase chain reaction was used to investigate the expression levels of UBE2Q2 gene in a collection of 21 breast cancer tissues matched with normal adjacent counterparts. Immunohistochemistry and Western blot testing were also performed on formalin-fixed, paraffin-embedded tissue sections by using a rabbit polyclonal antibody that we...
Pragmatics versus contrarians: how does one resolve their differences with respect to oral cancer screening?
With an annual incidence of nearly 600,000 cases, oral and pharyngeal squamous cell carcinoma is the sixth most common malignancy in the world today. The American Cancer Society (ACS) estimates there will be over 35,000 new cases in the United States in 2010, with nearly 8,000 deaths from the disease. When focusing specifically on the oral cavity, it is estimated there will be over 23,000 new cases and more than 5,300 deaths. Despite advances in therapy, long-term survival for patients with oral cavity cancers has remained largely unchanged. Several factors contribute to this poor outcome. First, oral cancer is often diagnosed in an advanced stage. The 5-year survival rate of early stage disease is approximately 80%, while the survival drops to about 20% for late stage disease. Second, as ...<div id="medworm"><p><b><i>MedWorm Message:</i></b> Get the very latest Swine Flu news via the MedWorm <b><a href="http://www.medworm.com/rss/search.php?qu=%2Bswine+%2B%28influenza+flu%29&t=Swine+Flu&f=infectiousdiseases&r=Any&o=d" target ="_self">Swine Flu RSS news feed</a></b> - updated hourly from thousands of authoritative health and news sources.</p></div>

B Cells Are Required for Optimal CD4+ and CD8+ T Cell Tumor Immunity: Therapeutic B Cell Depletion Enhances B16 Melanoma Growth in Mice.
Authors: Dilillo DJ, Yanaba K, Tedder TF B lymphocytes can both positively and negatively regulate cellular immune responses. Previous studies have demonstrated augmented T cell-mediated tumor immunity in genetically B cell-deficient mice, suggesting that therapeutic B cell depletion would enhance tumor immunity. To test this hypothesis and quantify B cell contributions to T cell-mediated anti-tumor immune responses, mature B cells were depleted from wild-type adult mice using CD20 mAb prior to syngeneic B16 melanoma tumor transfers. Remarkably, s.c. tumor volume and lung metastasis were increased 2-fold in B cell-depleted mice. Effector-memory and IFN-gamma-or TNF-alpha-secreting CD4(+) and CD8(+) T cell induction was significantly impaired in B cell-depleted mice with tumors. Tumor A...
Blockade of Programmed Death Ligand 1 Enhances the Therapeutic Efficacy of Combination Immunotherapy against Melanoma.
In this study, in vitro blockade of PD-L1 interaction on DCs led to enhanced IFN-gamma production and cytotoxicity by Ag-specific T cells. In vivo, the systemic administration of anti-PD-L1 Ab plus melanoma peptide-pulsed DCs resulted in a higher number of melanoma peptide-specific CD8(+) T cells, but this combination was insufficient to delay the growth of established B16 melanoma. Although the addition of 600 rad of total body irradiation delayed tumor growth, further adoptive transfer of Ag-specific CD8(+) T cells was needed to achieve tumor regression and long-term survival of the treated mice. Lymphopenic mice treated with anti-PD-L1 Ab demonstrated increased activation and persistence of adoptively transferred T cells, including a higher number of CD8(+) T cells infiltrating the tumo...
Ornithine decarboxylase mRNA expression in curatively resected non-small-cell lung cancer.
Conclusion: In this study, ODC is shown to have a prognostic potential in NSCLC. Low levels of tODC expression are associated with a more aggressive tumor biology. Also, an increase of ODC mRNA expression during carcinogenesis seems to have a favorable prognostic effect. Measuring the ODC expression in patients with NSCLC could aid in further chemotherapy decisions. Our results suggest that further investigation of ODC mRNA expression in NSCLC may be warranted.

p38 Regulates Pigmentation via Proteasomal Degradation of Tyrosinase [Signal Transduction]
The synthesis of melanin pigments, or melanogenesis, is regulated by the balance of a variety of signal transduction pathways. Among these pathways, p38 MAPK signaling was found to be involved in stress-induced melanogenesis and to be activated by -melanocyte-stimulating hormone (-MSH) and ultraviolet irradiation. Previous studies have shown that -MSH-stimulated melanogenesis can be inhibited by blocking p38 MAPK activity with SB203580, a pyridinyl imidazole compound. Consistent with this, we observed that pyridinyl imidazoles (SB203580 and SB202190) inhibited both basal and -MSH-induced melanogenesis in B16 melanoma cells. However, SB202474, which has no ability to inhibit p38 MAPK activity and is usually used as a negative control compound in p38 MAPK studies, also suppressed melanin syn...

The aberrant upregulation of FOXM1 serves as a first hit where cells acquire genomic instability which in turn predisposes cells to a second hit whereby DNA-damage checkpoint response (eg. p53 or p16) is abolished to allow damaged cells to proliferate and accumulate genetic aberrations/mutations required for cancer initiation.

Second salvage surgery for re-recurrent oral cavity and oropharynx carcinoma
Salvage surgery is considered the best treatment approach for patients with recurrent oral carcinoma. Unfortunately, 50% to 60% of the patients who undergo salvage surgery will develop further locoregional recurrence, and they are not usually considered for further treatment. Our aim in this study was to report our experience with a second salvage surgery for selected patients with re-recurrent oral cavity and oropharyngeal squamous cell carcinoma (SCC).Forty-one patients underwent a second salvage surgical procedure, with curative intention for re-recurrent oral cancer. The surgical treatment used was wide local resection in 34 cases, neck dissection in 9 cases, and isolated neck dissection in 7 cases.Cancer-specific survival (CSS) rate in 3 years was at 20%. Patients with re-recurrence i...

Autosomal dominant and sporadic monocytopenia with susceptibility to mycobacteria, fungi, papillomaviruses, and myelodysplasia
We identified 18 patients with the distinct clinical phenotype of susceptibility to disseminated nontuberculous mycobacterial infections, viral infections, especially with human papillomaviruses, and fungal infections, primarily histoplasmosis, and molds. This syndrome typically had its onset in adulthood (age range, 7-60 years; mean, 31.1 years; median, 32 years) and was characterized by profound circulating monocytopenia (mean, 13.3 cells/µL; median, 14.5 cells/µL), B lymphocytopenia (mean, 9.4 cells/µL; median, 4 cells/µL), and NK lymphocytopenia (mean, 16 cells/µL; median, 5.5 cells/µL). T lymphocytes were variably affected. Despite these peripheral cytopenias, all patients had macrophages and plasma cells at sites of inflammation and normal immunogl...

Photoacoustics Technology Could Make Some Lab Processes More Efficient, Says MU Researcher
Knowing the stage of a patient's melanoma is important when choosing the best course of treatment. When the cancer has progressed to the lymph nodes, a more aggressive treatment is needed. Examining an entire lymph node for cancer takes much effort and time; a new technique might help make the process more efficient. University of Missouri researchers in the Christopher S. Bond Life Sciences Center are studying how photoacoustics, or a laser-induced ultrasound, could help scientists locate the general area of the lymph node where melanoma cells could be residing...

Effects of cytokines on long control region transcriptional activity in high-risk cutaneous human papillomavirus types 5 and 8
Abstract  Cytokines play an important role in the control of mucosal HPV transcription. However, there is little data available on cutaneous HPVs, which are associated with non-melanoma skin cancers. Here, we describe a cell-based assay exploiting HaCaT keratinocytes stably transfected with a reporter construct containing the long control region (LCR) regulatory sequence of gene transcription in HPV-5 and HPV-8. This novel assay has allowed the first systematic analysis of the effects of cytokines on HPV-5 and HPV-8 LCR activity and provides a valuable tool for the search for cutaneous HPV-gene expression inhibitors.

Decreased nuclear expression and increased cytoplasmic expression of ING5 may be linked to tumorigenesis and progression in human head and neck squamous cell carcinoma
Conclusions  Our results suggest that a decrease in nuclear ING5 localization and cytoplasmic translocation are involved in tumorigenesis and tumor differentiation in HNSCC. Nuclear ING5 may modulate the transactivation of target genes, and may promote apoptosis and cell cycle arrest by interacting with the p300 and p21 proteins. ING5 may function as a tumor suppressor gene or oncogene tightly linked with p53 status, and may play an important role in the prognosis of HNSCC patients. Therefore, we propose that ING5 represents a novel potential molecular therapeutic target for HNSCC.

CD10, p63 and CD99 expression in the differential diagnosis of atypical fibroxanthoma, spindle cell squamous cell carcinoma and desmoplastic melanoma
Conclusion: CD10 positivity is relatively specific in this context for the diagnosis of AFX. Its utility is enhanced when only strong, diffuse membranocytoplasmic staining is considered as a positive result. In contrast to prior reports, p63 was not found to be highly sensitive for SCC. Similarly, CD99 showed no preferential staining of any single diagnostic group of lesions. Kanner WA, Brill LB, Patterson JW, Wick MR.

"Transcription physiology" of pigment formation in melanocytes: central role of MITF
Please cite this paper as:"Transcription physiology" of pigment formation in melanocytes: central role of microphthalmia-associated transcription factor (MITF). Experimental Dermatology 2010.Abstract: Melanin production is the primary mechanism protecting human skin against the UV light-induced damage. The polymeric compound melanin is synthesized within melanocytes in the specialized subcellular organelles, termed melanosomes, which are then transferred to surrounding keratinocytes. The genes for melanin synthesis and deposition are coordinately expressed in melanocytes. The transcription factor MITF, which has been reported to activate more than 25 genes in pigment cells, has emerged as an essential regulator not only for melanocyte development, proliferation and survival, but also for t...

Pattern of lymph node metastases and its implication in radiotherapeutic clinical target volume in patients with thoracic esophageal squamous cell carcinoma: A report of 1077 cases.
CONCLUSIONS: T stage, the length of tumor and the histologic differentiation influence the pattern of lymph node metastases in thoracic ESCC. These factors should be considered comprehensively to design the CTV for radiotherapy (RT) of thoracic ESCC. Selective regional irradiation including the correlated lymphatic drainage regions should be performed as well.

Detecting early oral cancer: narrowband imaging system observation of the oral mucosa microvasculature
Abstract: The aim of this study was to analyze and describe the intrapapillary capillary loops (IPCL), which are a feature of early oral neoplastic lesions, using a narrowband imaging (NBI) system. Forty-one patients (26 men, 15 women; mean age, 52.34 years; range, 23?83 years) presenting with non-neoplastic or neoplastic lesions, and normal cases, were examined using the prototype Evis Lucera Spectrum (Olympus Co.). The images were analyzed and an IPCL classification was devised. All normal cases (n=10) had regularly distributed capillary loops of the same shape (type I). Non-neoplastic lesions (n=8) had mild changes of the capillary loops (types II and III) and neoplastic lesions (n=23) were irregularly distributed and had several loop shapes (types III and IV). The microvascular organ...

This means that if we exercise and control our
weight, our bodies will be healthier and they will help us to
fight off more illnesses, such as skin cancer, than we could if
we were overweight.

So there are serious links with exercise and the reduction of
skin cancer, but what is the best exercise to participate in?

The Best Types of Exercise:

Generally any exercise is good, but there are some that are
better than others. Walking may be considered to be one of the
best methods of exercise as it is the easiest to do, but some
experts argue that walking is just not enough to provide the
best results. However, if you power walk then you are going to
achieve better results than slow walking!

Anything that gets the heart rate going and that makes you
sweat is definitely the best type of exercise that you can do.
Never try and do too much however, you should only go at a pace
which you can handle and which is right for you, otherwise you
could end up doing more harm than good.

So, whether you want to do jogging, horse riding, swimming or
aerobics, as long as it gets your heart rate going, it is doing
you some good. Aim to do at least thirty minutes each day, that
way you will get the best possible results for you. You should
notice that your skin starts to look a little clearer and that
you feel more energized after around a week.

Overall, any exercise you choose to do will benefit the skin
and help you to fight off cells. Keeping yourself
fit and healthy has never been as easy as it is today so there
really is no excuse!
