Biological Activity

Induces cell death and increases the level of reactive oxygen species (ROS) in cancer cells with both wild-type and normal p53. Also inhibits the growth of spontaneous malignant breast tumors in mice. Displays little effect on normal cells. Rapidly depletes androgen receptor expression in human prostate cancer cells via a ROS-dependent, proteasome-mediated mechanism.

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.

Pathways for Piperlongumine


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.
