p53 Activation: A Case against Sir [PDF]

open access: yesCancer Cell, 2008
The p53 tumor suppressor is a critical transcription factor for controlling cell growth and apoptosis during times of cellular stress. In this issue of Cancer Cell, Lain et al. have used a p53-responsive reporter gene as the readout for screening small-molecule activators of p53 that could potentially reduce tumor growth. Using this approach, tenovin-6
