Biochem/physiol Actions

Poly (ADP-ribose) polymerase 1 (PARP1) has a role in DNA repair and acts as a facilitator of homologous recombination. It controls transcription by modulating chromatin structure and altering DNA methylation patterns. The protein functions as a co-regulator of transcription factors and associates with chromatin insulators. PARP1 also has an important role in protection of the cardiovascular system.

In this study, we explored the antitumor activities of the PARP inhibitor AZD2281 (Olaparib) and the pan-Bcl-2 inhibitor GX15-070 (Obatoclax) in six pancreatic cancer cell lines. While both agents were able to cause growth arrest and limited apoptosis, the combination

Although prostate cancer responds initially to androgen ablation therapies, progression to castration-resistant prostate cancer (CRPC) frequently occurs. Heat shock protein (Hsp) 90 inhibition is a rational therapeutic strategy for CRPC that targets key proteins such as androgen receptor (AR) and
