Biological Activity

Inhibitor of Hdm2 ubiquitin ligase (E3). Blocks Hdm2-mediated ubiquitylation and proteasomal degradation of p53; activates p53-dependent transcription. Induces apoptosis in several tumor cell lines that express wild-type p53 such as LOX-IMVI, A549, HT1080 and U2OS.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
