Biological Activity for Gambogic acid

Gambogic acid is an apoptosis inducer in several tumor cell lines including T47D cells. Activates caspases (EC50 values are 0.78 - 1.64 μM) and competitively inhibits antiapoptotic Bcl-2 family proteins (IC50 values are 1.47, 1.21, 2.02, 0.66, 1.06 and 0.79 μM for Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1 respectively). Reverses gefitinib-resistance in mice bearing tumors with EGFR-T790M mutation. Also blocks Kir2.1 channels (EC50 ≤ 100 nM).

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.
