Apoptosis
New research on apoptosis from Case Western Reserve University summarized
May 12th, 2009
According to a study from the United States, "Transforming growth factor-beta (TGF-beta) functions as a tumor suppressor of the prostate through mechanisms that remain unresolved. Although TGF-beta receptors directly activate both Smads 2 and 3, to date, Smad3 has been shown to be the essential mediator of most Smad-dependent TGF-beta responses, including control of gene expression, cell growth, apoptosis, and tumor suppression." "Using a robust lentiviral short hairpin RNA system to silence Smads 2 and/or 3 in the NRP-152 nontumorigenic rat prostate basal epithelial cell line, we provide the first evidence for Smad2 as a critical mediator of TGF-beta-induced apoptosis...
