Telomerase gene mutation immortalizes deadly skin cancer

About ten percent of all cases of malignant melanoma are familial cases. The genome of affected families tells scientists a lot about how the disease develops. Prof. Dr. Rajiv Kumar of the German Cancer Research Center together with Prof. Dr. Dirk Schadendorf from Essen University Hospital studied a family where 14 family members were affected by malignant melanoma.

Reducing the level of mutant p53 gene increases susceptibility to cancer treatment

Scientists from the National Cancer Centre Singapore (NCCS) have discovered the workings of the gene that has been hindering treatment response in cancer patients. This discovery was made after 5 years of studying the mutant form of the p53 gene, the major tumor suppressor in humans, which is generally found mutated in over 50% of all type of human cancers.

Hepatitis B virus X protein represses miRNA-148a to enhance tumorigenesis

Viruses prompt oncogenic transformation by genetically altering infected cells. Several recent studies have demonstrated that viruses alter the expression of microRNAs, non-coding RNA molecules that can block the expression of target genes.

Florida Atlantic University announces $3M gift to endow medical student scholarships

Florida Atlantic University's Charles E. Schmidt College of Medicine has announced a $3 million gift to endow medical student scholarships. The endowment will be named the "Dr. Morton and Cynthia Levitt Endowed Scholarship for Medical Education," and the announcement was made during the Schmidt College of Medicine's inaugural "Your Medical School" celebration honoring Dick and Barbara Schmidt.

Key link between stem cell factors that fuel ovarian cancer's growth and patient prognosis

Researchers at Yale School of Medicine have identified a key link between stem cell factors that fuel ovarian cancer's growth and patient prognosis. The study, which paves the way for developing novel targeted ovarian cancer therapies, is published online in the current issue of Cell Cycle.

Link between Parkinson's and benomyl

For several years, neurologists at UCLA have been building a case that a link exists between pesticides and Parkinson's disease. To date, paraquat, maneb and ziram - common chemicals sprayed in California's Central Valley and elsewhere - have been tied to increases in the disease, not only among farmworkers but in individuals who simply lived or worked near fields and likely inhaled drifting particles.

Few alcohol-related story ideas from The Methodist Hospital

The holidays are a time to consume -- food, gifts, and spirits. Here are a few alcohol-related story ideas from The Methodist Hospital. Because alcohol's effects on human physiology are complex, advice about is often contradictory.

New lung cancer loci found

Genome-wide analysis has identified three new susceptibility loci for lung cancer in a large cohort of never-smoking women in Asia.

Biomolecular imaging: an interview with Professor Roger Reddel

The reason Children’s Medical Research Institute (CMRI) exists is to find ways to treat or prevent childhood disease. Our research programs are focussed on the areas of cancer cell growth, nerve cell signalling, embryology and gene therapy. These four programs have a shared aim of translating novel findings into new treatments for the benefit of families everywhere.

High vitamin D levels associated with protection against bladder cancer

High levels of vitamin D are associated with protection against bladder cancer, according to a multidisciplinary study coordinated by molecular biologists and epidemiologists from the Spanish National Cancer Research Centre (CNIO), the conclusions of which are being published today in the Journal of National Cancer Institute (JNCI) .

Aspirin improves colorectal cancer survival in tandem with gene mutation

Aspirin significantly improves survival in colorectal cancer patients who have a mutation in a carcinogenesis-associated signaling pathway, the results of a US and Japanese study indicate.

Epigenetic alteration associated with increased risk of breast cancer

Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is called "twin discordance". But how can people who have the same genetic sequence present different pathologies and at different ages? The explanation partly lies in the fact that the chemical signals added in the DNA to "switch off" or "switch on" genes can be different. These signals are known as epigenetic marks.

No link between folic acid, vitamin B6 and 12 and increased risk of colorectal adenoma

Combined folic acid, vitamin B6 and vitamin B12 supplements had no statistically significant effect on the risk of colorectal adenoma among women who were at high risk for cardiovascular disease, according to a study published October 12 in the Journal of the National Cancer Institute.

Scientists resolve new molecular circuit controlling cellular metabolism

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism.

Study to look at whether maternal exercise during pregnancy can reduce risk of cancer in offspring

If a mother exercises during her pregnancy, will that benefit her children? Researchers at the University of Kentucky have initiated studies to look into the idea: a group from the UK Graduate Center for Nutritional Sciences has received a $100,000 grant from the National Institutes of Health to study whether maternal exercise during pregnancy can lead to a reduced risk of cancer in offspring.

Gum disease bacteria linked to pancreatic cancer risk

People with high levels of antibodies to bacteria linked to periodontal disease have an increased risk for pancreatic cancer, while the risk is reduced in those with increased antibodies to oral commensal bacteria, say researchers.

RRM2 may be a facilitating factor in colorectal cancer and UV-induced DNA damage repair

Colorectal cancer (CRC) is the leading cause of cancer-related death worldwide. In addition, the incidence and mortality rates of colorectal cancer are on the rise. Recently, metabolic genes have received increasing and specific attention due to their potential role in carcinogenesis.
