The expression of p53 and Mdm2 is closely related. In an article published this week in the Cancel Cell review, Robin Fahraeus and his collaborators from Inserm Unit 940 ("Therapeutic Targets for Cancer"), demonstrate that cellular response to DNA damage requires involvement from the protein kinase ATM so that Mdm2 can positively or negatively control protein p53. Much focus is placed on protein p53 in cancer research. Discovered in 1979, p53 precisely regulates cell proliferation and...

(Ivanhoe Newswire)- Cholesterol lowering statins seem to be effective against breast cancer in some patients. Research shows that a mutation in a single gene may be a way for researchers to identify tumors that are likely to respond to statin therapy. Carol Prives and her team at Columbia University devised an experiment to study cancer cells grown in an artificial system that resembles the three-dimensional structures in a human breast. The researchers learned that cells carrying...

Cholesterol-lowering statins seem to keep breast cancer at bay in some patients. Now researchers reporting in the January 20th issue of the journal Cell, a Cell Press publication, provide clues about how statins might yield those unexpected benefits. The findings also suggest that mutations in a single gene could be used to identify tumors likely to respond to statin therapy. "The data raises the possibility that we might identify subsets of patients whose tumors may respond to statins,"...

Inherited mutation links exploding chromosomes to cancer An inherited mutation in a gene known as the guardian of the genome is likely the link between exploding chromosomes and some particularly aggressive types of cancer, scientists at the European Molecular Biology Laboratory (EMBL), the German Cancer Research Centre (DKFZ) and the University Hospital, all in Heidelberg, Germany, have discovered. Their study, published online today in Cell, also presents the first whole genome sequence...

A well-known protein complex responsible for controlling how DNA is expressed plays a previously unsuspected role in preventing pancreatic cancer, according to researchers at the Stanford University School of Medicine. Technological advances in the way researchers can compare normal and tumor DNA showed that the gene for at least one subunit of the multi-subunit SWI/SNF protein complex was either deleted, mutated or rearranged in about a third of the 70 human pancreatic cancers that the...

Either heart failure or diabetes alone is bad enough, but oftentimes the two conditions seem to go together. Now, researchers reporting in the January Cell Metabolism appear to have found the culprit that leads from heart failure to diabetes and perhaps a novel way to break that metabolic vicious cycle. "Our findings clarify the reasons why the incidence of heart failure is high among diabetic patients, why the prevalence of insulin resistance is increased in heart failure patients, and...

SAN DIEGO, Dec. 13, 2011 /PRNewswire/ -- Cylene Pharmaceuticals, Inc. announced today that two of its first-in-class agents, both inhibitors of newly-validated targets, have demonstrated encouraging activity in several preclinical models of high risk leukemias, cancers for which there are limited clinical treatment options. Dr. Ross Hannan of the Peter MacCallum Cancer Centre (PMCC), Melbourne, Australia, reported how CX-5461, a targeted inhibitor of RNA Polymerase I (Pol I),...

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes from cell metabolism to programmed cell death. Now, scientists from the Florida campus of The Scripps Research Institute have identified the importance of a novel protein-regulating mechanism -- called sulfenylation -- that is similar to phosphorylation and may, in fact, open...

Study published online today in Nature Genetics BGI, the world's largest genomics organization, announced that a study on frequent mutation of genes encoding ubiquitin-mediated proteolysis pathway (UMPP) components in clear cell renal cell carcinoma (ccRCC) is published online today in Nature Genetics. In addition to BGI, co-leaders of the study included Peking University Shenzhen Hospital, Shenzhen Second People's Hospital, among others. The study reveals that alteration of UMPP may...

MK 1775, a small, selective inhibitor molecule, has been found to be active against many sarcomas when tested by researchers at Moffitt Cancer Center in Tampa, Fla. Their findings, recently appearing in Molecular Cancer Therapeutics, published by the American Association for Cancer Research, suggest that a badly needed new agent against sarcomas - especially sarcomas affecting children - may be at hand. According to corresponding author Soner Altiok, M.D., Ph.D., sarcomas are rare forms of...
