BACKGROUND Distant prostate cancers are commonly hormone refractory and exhibit increased growth no longer inhibited by androgen deprivation therapy. Understanding all molecular mechanisms contributing to uncontrolled growth is important to obtain effective treatment strategies for hormone refractory prostate cancers (HRPC). The aryl hydrocarbon receptor(More)
We have obtained initial evidence supporting a new model for the human disease ataxia-telangiectasia (A-T), in which the A-T and p53 genes play crucial roles in a signal transduction network that activates multiple cellular functions in response to DNA damage. Three of the model's predictions were tested. (1) Disrupting cell cycle checkpoints should(More)
The phytopathogenic bacterium Erwinia chrysanthemi produces a group of pectolytic enzymes able to depolymerise the pectic compounds in plant cell walls. The resulting tissue maceration is known as soft rot disease. The degraded pectin products are transported by 2-keto-3-deoxygluconate permease into the bacterial cell, where they serve as carbon and energy(More)
