PARP is a family of proteins involved in a number of cellular processes involving mainly DNA repair and programmed cell death. The PARP family comprises 17 members. They have all very different structures and functions in the cell. PARP1, PARP2, VPARP (PARP4), Tankyrase-1 and -2 (PARP-5a or TNKS, and PARP-5b or TNKS2) have a confirmed PARP activity. Others include PARP3, PARP6, TIPARP (or PARP7), PARP8, PARP9, PARP10, PARP11, PARP12, PARP14, PARP15, and PARP16. PARP is found in the cell’s nucleus. The main role is to detect and signal single-strand DNA breaks (SSB) to the enzymatic machinery involved in the SSB repair.

Polyporenic acid C reduces the phosphorylation level of Akt (Ser473), increases the phosphorylation of PTEN and p53 (Ser15), and activates JNK. Polyporenic acid C induces Apoptosis. Polyporenic acid C shows anticancer activity against non-small cell lung cancer.
