Fractionated Ocimum gratissimum leaf extract inhibit prostate cancer (PC3·AR) cells growth by reducing androgen receptor and survivin levels

J Health Care Poor Underserved. 2013 Nov;24(4 Suppl):61-9. doi: 10.1353/hpu.2014.0006.

Abstract

In this study, the antiproliferative activity of the organic solvent-soluble and aqueous extracts of Ocimum gratissimum leaf against the prostate cancer cells PC3·AR were evaluated by their inhibitory effects on the Androgen Receptor (AR) and Survivin protein. Two organic solvent-soluble extracts P2 and P3-2, and a water- soluble extract, PS/PT1, were found to reduce AR and Survivin levels in a time-dependent manner. In addition, extract PS/PT1, also exhibited the inhibitory activity in a dose-dependent manner. This is the first time that the inhibitory eff ects of O. gratissimum extracts have been evaluated on the Androgen Receptor (AR) and Survivin protein. The results encouraged the further studies of O. gratissimum as a potential treatment of prostate cancer.
