The mechanism of action of these PPARa receptors in the vascular wall was alsoelucidated. The receptors exert at least part of their anti-inflammatory effectby interfering with a signaling pathway called NFkB, which is a......udy. The team also looked at tissue samples for a marker of benign disease -- calledhyperplastic epithelial tissue -- and two markers associated with increased riskof prostate cancer -- the presence of precancerous lesions known as PIN (prostateintraepithelial neoplasia) and the rate of cell proliferation ...Jefferson Physician Warns Further Study Of DHEA's Safety Needed
