Sequencing of the oyster mushroom genome
...that make up the oyster mushroom, i.e. the genetic constitution
of the organism. Life appeared on Earth some 3,000 million years ago. The evolution undergone by this fungus whose DNA is to be purified, has been through these 3,000 million years, as has the human being. Thus, within its genome there is 3,000 mil...
Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm
...This interval is partly dependent on one's genetic constitution
and, moreover, genes also play a role in sudden cardiac death. "There's a great deal of evidence out there that having a too long or too short QT interval is a risk factor for sudden cardiac death," says the study's co-first author, Dan Arking, Ph.D...
Studies throw light on biomarkers which predict the subsets of patients where gefitinib has the greatest benefit
...for genotyping studies (all or part of the genetic constitution
of an individual or group) and survival. Median overall survival was 194 days; 55 patients had stable disease, 15 experienced partial response, and two had complete responses. "Investigators identified four distinct haplotypes (different combinatio...
