Biological Activity for YM 155

YM 155 is a survivin suppressor. Down-regulates survivin expression and sensitizes human NSCLC cell lines to radiation. Enhances radiation-induced tumor regression in nude mice bearing NSCLC xenografts. Also induces apoptosis in TRAIL-resistant glioma cells in vitro. YM 155 is also an inhibitor of ILF3 (interleukin enhancer binding factor 3), an RNA-binding protein. It reduces thermal and mechanical hypersensitivity in a mice model of inflammatory pain.

Programmed Cell Death Poster

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.

Apoptosis Signaling Pathway

Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
