Epigenetic ‘memory’ Key to Nature Versus Nurture
Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at the John Innes Centre have made a discovery, reported July 24th in Nature, that explains how an organism can create a biological memory of some variable condition,...
Genetic Variant Linked to Development of Liver Cancer in Hepatitis C Virus Carriers
A genome-wide study by researchers at the RIKEN Center for Genomic Medicine, Hiroshima University Hospital and Sapporo-Kosei General Hospital has identified a genetic variant associated with the development of liver cancer in chronic hepatitis C virus...
Ovarian Cancer Genome Mapped Opening the Door to Personalized Medicine
Scientists have developed the first comprehensive catalog of the genetic aberrations responsible for an aggressive type of ovarian cancer that accounts for 70 percent of all ovarian cancer deaths.
Genome Editing, a Next Step in Genetic Therapy, Corrects Hemophilia in Animals
Using an innovative gene therapy technique called genome editing that hones in on the precise location of mutated DNA, scientists have treated the blood clotting disorder hemophilia in mice. This is the first time that genome editing, which precisely...
Researchers Improve Method for Finding Genetic Mistakes That Fuel Cancer
A dramatically better computer tool for finding the genetic missteps that fuel cancer has been developed by St. Jude Children’s Research Hospital – Washington University Pediatric Cancer Genome Project investigators. Researchers are using the...
USDA-led Consortium Sequences Genome of Key Wheat Pathogen
A U.S. Department of Agriculture (USDA)-led consortium of scientists has fully sequenced the genome of the pathogen that causes the wheat disease known as septoria tritici blotch, which can cause significant yield losses. According to the International...
Extraordinary DNA Repair Safeguards Genome Integrity
Heterochromatin (purple) accounts for a third of the chromatin in both humans and fruit flies. Some heterochromatin forms the telomeres that cap the ends of the chromatids, and much is concentrated near the centromere, where sister chromatids are joined....
Host Change Alters Toxic Cocktail
Larvae of the leaf beetle Chrysomela lapponica attack two tree species: willow and birch. To fend off predator attacks, their larvae produce toxic butyric acid esters or salicylaldehyde, whose precursors they ingest with their leafy food. Scientists found...
