PARP
poly ADP ribose polymerase
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.

Cyproheptadine-d3
0 ImagesCat. No.: HY-B1622SCAS No.: 2712455-05-3Cyproheptadine-d3 is the d3-labeled Cyproheptadine (HY-B1622). Cyproheptadine acts as a p38 MAP kinase activator, CHK2 activator, histamine H1 receptor inhibitor and serotonin receptor inhibitor. Cyproheptadine mediates cell cycle arrest via G1 phase arrest, G1/S transition arrest, G0/G1 phase arrest, reduced expression of cyclins D1/D2/D3, upregulated expression of HBP1, p16, p21, p27, and decreased phosphorylation of retinoblastoma protein. Cyproheptadine induces Apoptosis by increasing PARP and cleaved PARP, as well as activating the mitochondrial caspase pathway. Cyproheptadine inhibits tumor growth with extremely low toxicity to normal cells. Cyproheptadine can be used in research related to hepatocellular carcinoma, multiple myeloma and acute myeloid leukemia.
