Project description:Rauwolfia vomitoria extract is an herbal preparation of the root bark of a plant in the tropical forests of Africa, which could inhibit Benign prostatic hyperplasia (BPH). Characterizing the molecular alterations of BPH1 and WPMY-1 cells treated with RWF is important for understanding the molecular mechanisms of RWF inhibiting BPH. We used microarrays to detail the RNA expression.
