IPSWICH, Mass., Oct. 14 /PRNewswire/ -- New England Biolabs (NEB) has launched a suite of new and validated products designed to simplify DNA methylation analysis for epigenetics researchers. These enzyme-based solutions address some of the challenges of the current methods, including the lack of a reproducible method for the analysis and quantitation of 5-hydroxymethlcytosine (5-hmC) in the epigenome.

A collaboration between physicians and scientists at UNC Lineberger Comprehensive Cancer Center and the University of Texas M.D. Anderson Cancer Center has demonstrated that a biomarker called TCF21 may be used to develop a potential screening test for early-stage lung cancer. Despite the fact that lung cancer is the leading cause of cancer deaths worldwide, early-stage lung cancer is difficult to diagnose. A number of proposed screening tests, including screening CT scans and serum markers,...

For the first time, UK scientists have reported direct evidence that taking up smoking results in epigenetic changes associated with the development of cancer. The results were reported at the 35th Congress of the European Society for Medical Oncology (ESMO) in Milan, Italy. The link between smoking and cancer has been established for decades, explained Dr Yuk Ting Ma from the Cancer Research UK Institute of Cancer Studies, Birmingham, who presented the results. Smoking is the single biggest...

Post-translational modifications of histones play an important role in regulating chromatin dynamics and function. One such modification, methylation, is involved in the regulation of the epigenetic program of a cell, determining chromatin structure, and regulating transcription. Methylation of histones occurs on both lysine and arginine residues, and until recently, was thought to be an irreversible process. The recent discovery of histone demethylases revealed that histone methylation is...

Colon cancer is the second most common cancer in the United States and causes more than 50,000 deaths each year. It has been known for some time that mutations in the APC gene occur in more than 85 percent of all sporadic colon cancers. Now researchers at Huntsman Cancer Institute at the University of Utah demonstrate in a study featured today in Cell the mechanism by which mutation of the APC gene affects a cellular process known as DNA methylation. DNA methylation is a chemical modification...

Johns Hopkins scientists who specialize in unconventional hunts for genetic information outside nuclear DNA sequences have bagged a weighty quarry "” 13 genes linked to human body mass. The experiments screened the so-called epigenome for key information that cells remember other than the DNA code itself and may have serious implications for preventing and treating obesity, the investigators say. "Some of the genes we found are in regions of the genome previously suspected but not...

Potential application for stem cell therapies Having charted the occurrence of a common chemical change that takes place while stem cells decide their fates and progress from precursor to progeny, a Johns Hopkins-led team of scientists has produced the first-ever epigenetic landscape map for tissue differentiation. The details of this collaborative study between Johns Hopkins, Stanford and Harvard appear August 15 in the early online publication of Nature. The researchers, using blood-forming...

Grown-ups aren't the only ones making exciting scientific discoveries these days. Two middle school students from Wisconsin joined a team of scientists who are reporting the first glimpse of the innermost structure of a key bacterial enzyme. It helps activate certain antibiotics and anti-cancer agents so that those substances do their job. Their study appears in ACS' weekly journal Biochemistry. The student co-authors of the study are from Edgewood Campus Middle School in Madison and...
