Abstract Poly(ADP-ribose) polymerase 1 (PARP-1) is reported to be involved in DNA repair and is now recognized as
a key regulator in carcinogenesis. However, the potential role and the molecular mechanism underlying the
effect of PARP-1 on osteosarcoma (OS) cells have not been elucidated. In this study, the results showed that
knockdown of PARP-1 resulted in decreased cell proliferation, increased cell apoptosis, and G0/G1 phase arrest
in U2OS cells. In addition, increased expression of active caspase 3 and Bax, but reduced Bcl-2, cyclin D1,
and phosphorylated extracellular signal regulated kinase 1/2 (pERK1/2) were observed in PARP-1 knockdown More >
