Gag order: how DNA silencing can promote cancer
— 2 Apr 2011 11:40 | HealthCells control which genes they express by multiple mechanisms, one of which is the direct modification of DNA with small molecules. Methylation of genes effectively silences them, and…
Genetic alteration may represent early stage of smoking-induced cardiovascular damage
— 1 Apr 2011 15:00 | HealthA new study uncovers a previously unrecognised link between tobacco smoking and a gene known to influence the cardiovascular system, possibly identifying an early stage of smoking-associated…
Blood test may find markers of bladder cancer risk
— 23 Feb 2011 17:19 | HealthKnowing that it is impossible to catalogue all the carcinogenic exposures a person has had in life and then assess them, Brown University researcher Carmen Marsit is looking for a more…
Cell reprogramming leaves a 'footprint' behind
— 3 Feb 2011 18:18 | BiologyReprogramming adult cells to recapture their youthful 'can-do-it-all' attitude appears to leave an indelible mark, found researchers at the Salk Institute for Biological Studies. When…
Molecular mechanism links stress with predisposition for depression
— 27 Jan 2011 17:41 | HealthA new study provides insight into how stress impacts the brain and may help to explain why some individuals are predisposed to depression when they experience chronic stress. The research,…
Biomarker test shows promise for melanoma diagnosis
— 25 Jan 2011 18:53 | HealthA new study shows that a test of biomarkers for DNA methylation is technically feasible and could aid in earlier, more precise diagnosis of melanoma…
Fat associated with chemical changes in DNA that may help explain obesity-related disease
— 21 Jan 2011 19:50 | HealthFat appears to associate with some distinctive chemical changes in the DNA - a finding that may help explain why obesity can increase the risk for chronic problems such as cardiovascular…
High red blood cell folate levels linked to silenced tumour-suppressors
— 3 Jan 2011 15:56 | HealthPeople with higher levels of folate in their red blood cells were more likely to have two tumour-suppressing genes shut down by methylation, a chemical off switch for genes, researchers…
Insight offers new angle of attack on variety of brain tumours
— 16 Dec 2010 17:04 | HealthA newly published insight into the biology of many kinds of less-aggressive but still lethal brain tumours, or gliomas, opens up a wide array of possibilities for new therapies, according…
Ovarian cancer advances when genes are silenced
— 14 Dec 2010 19:33 | HealthThere are many mechanisms that alter the activity of genes - direct changes to the DNA code like mutations and deletions, or changes that control when genes are switched on and off,…
