Gene research finds clues to AIDS survival Boston Globe November 5, 2010 For decades, they lived a mystery: Why were they able to survive with the AIDS virus, free of symptoms and the need for potent drugs , while so many others with the same germ ( virus ) turned deathly ill? Their innate ability to keep HIV infections in check intrigued researchers , who suspected these people , known as “controllers,’’ might carry clues to designing effective vaccines after nearly 30 years of frustration. Now, an international team of researchers , led by specialists in Boston, has cracked these HIV survivors’ genetic code , sifting through almost 1.4 million pieces of DNA to discover five amino acids that separate the small cadre of controllers from the vast majority who must take medication or face death.

Although authors of the study released yesterday cautioned that a vaccine remains years away , the discovery is testament to genetic tools that did not exist even a few years ago and to intellectual cross-pollination among hospitals, universities, and research institutes in Boston and Cambridge.

Low cholesterol, low prostate risk? By Marilynn Marchione Associated Press Men may protect more than their hearts if they keep cholesterol in line : Their chances of getting aggressive prostate cancer may be lower , new research suggests. One study found that men whose cholesterol was in a healthy range - below 200 - had less than half the risk of developing high-grade prostate tumors compared with men with high cholesterol. A second study found that men with lots of HDL, or "good cholesterol," were a little less likely to develop any form of prostate cancer than men with very low HDL. …….

The chance of developing aggressive tumors was 59 percent lower among men with cholesterol under 200. That's "a striking reduction in risk," Eric Jacobs and Susan Gapstur, epidemiologists with the American Cancer Society, write in an accompanying editorial.
