Expression data from human BPH1 and WPMY-1 cells treated with PAO.

Pao extract is an herbal preparation of the bark of an amazonian rain forest tree,Pao Pereira (Geissospermum vellosii),which could inhibit Benign prostatic hyperplasia (BPH).Characterizing the molecular alterations of BPH1 and WPMY-1 cells treated with PAO is important for understanding the molecular mechanisms of PAO inhibiting BPH. We used microarrays to detail the RNA expression. 8 samples were analyzed, 2 replicates. BPH1 and WPMY-1 cells were treated with vehicle or PAO (250μg/ml). These cells were used for RNA extraction and hybridization on Affymetrix microarrays.
