Hello! you have reached the official blog spot of our lab which is based at the University of Texas Health Science Center at San Antonio, Department of Urology - our main area of study is prostate cancer, nutrition, and epigenetics - but we also study changes in gene expression in benign-prostatic hyperplasia - we have made this blog so as we can share thoughts about the lab, papers that are just published and anything else remotely relevant at any time, and from anywhere!

Low folate protective against colon cancer?
Ed Giovannucci and his team have long touted the protective effects of dietary folate for colon cancer -- however in this epub, he presents three nested case-controlled studies that suggests exactly the opposite -- the findings suggest that folate intake doesn't directly determine plasma folate levels (meaning all those dietary questionnaire studies that were apparently validated for folate might be called into question...) -- and that in this "prospective" study, low folate was actually protective against colon cancer. I'm thinking that this study just opened up a whole load of new questions (but ones that I already had anyway, so I'm glad to see it!) - you can read about it here --
