Researchers find deficiency in anti-tumor protein can delay DNA repair after radiation treatment

Researchers at Moffitt Cancer Center have found that a deficiency in an important anti-tumor protein, p53, can slow or delay DNA repair after radiation treatment. They suggest that this is because p53 regulates the expression of two enzymes (JMJD2b and SUV39H1) that control the folding of DNA.

DNAzymes, gold nanoparticles and disease detection: an interview with Dr Chan and Kyryl Zagorovsky, University of Toronto

Gold nanoparticles are tiny spherical particles made out of gold atoms with sizes on nanometre scale. This is around 1,000 times smaller than the thickness of human hair.

University of Utah researchers develop novel technique to identify RNA cytosine methyltransferases

Researchers from Huntsman Cancer Institute at the University of Utah have developed a novel and powerful technique to identify the targets for a group of enzymes called RNA cytosine methyltransferases in human RNA.

Discovery reverses the prevailing model of how dividing cells monitor equal distribution of chromosomes

Ludwig researchers Arshad Desai and Christopher Campbell, a post-doctoral fellow in his laboratory, were conducting an experiment to parse the molecular details of cell division about three years ago, when they engineered a mutant yeast cell as a control that, in theory, had no chance of surviving. Apparently unaware of this, the mutant thrived.

Researchers find new potential target for anti-telomerase cancer therapy

Researchers at UT Southwestern Medical Center have found that alternative splicing - a process that allows a single gene to code for multiple proteins - appears to be a new potential target for anti-telomerase cancer therapy.

Taking painkillers before race leads to unrecognised problems

Many competitors try to prevent pain interfering with their performance by taking painkillers that are readily available in pharmacies and supermarkets, say the authors.

NCI investigators design genetically engineered mouse to study human lung squamous cell carcinoma

National Cancer Institute (NCI) investigators have designed a genetically engineered mouse for use in the study of human lung squamous cell carcinoma (SCC). SCC is a type of non-small cell lung carcinoma, one of the most common types of lung cancer, with a five-year survival rate of about 15 percent.

Running or jumping may worsen cartilage damage, MIT engineers find

Osteoarthritis, which affects at least 20 percent of adults in the United States, leads to deterioration of cartilage, the rubbery tissue that prevents bones from rubbing together.

CRISPR helps some bacteria evade mammalian immune system

CRISPR, a system of genes that bacteria use to defend themselves against viruses, has been found to be involved in helping some bacteria evade the mammalian immune system.

Preclinical studies show bladder cancers, mesotheliomas respond to treatment with ADI-PEG 20

Scientists from academic institutions reported at the 2013 annual American Association for Cancer Research meeting, results from preclinical studies which showed that certain bladder cancers and mesotheliomas have metabolic changes and are more likely to respond to treatment with ADI-PEG 20 (pegylated arginine deiminase) if they are deficient in the enzyme, argininosuccinate synthetase.

Death of heart tissue could be prevented with new medicines, say TUSM scientists

A major factor in the advance of heart disease is the death of heart tissue, a process that a team of scientists at Temple University School of Medicine's Center for Translational Medicine think could be prevented with new medicines.

Researchers create complete visual map of telomerase enzyme

Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.

Pharmacological study shows interactions between drugs can be detected with minute doses

Clinical pharmacologists at Heidelberg University Hospital have achieved major progress for improving the reliability of drugs. In a pharmacological study, they showed for the first time that interactions between drugs can be detected with minute doses in the range of nanograms.

US biochemist to be honoured with Inhoffen Medal Braunschweig, Germany

How do bacteria cope when exposed to toxic mercury, how are they able to outlast antibiotics, and how can they be killed using so-called "suicide inhibitors?" These are but a few of the many research topics US biochemist Christopher Walsh has devoted his career as a scientist to.

Study reveals inner workings of master regulator that controls diverse functions

New discoveries by a team of scientists at LSU Health Sciences Center New Orleans for the first time reveal the inner workings of a master regulator that controls functions as diverse as the ability of nerve cells to "rewire" themselves in response to external stimuli and the mechanism by which certain viruses hijack normal cellular processes to facilitate their replication that can ultimately lead to cancer. The research will be published in the April 12, 2013 issue of the Journal of Biological Chemistry.
