| Outline of Final Research Achievements |
Recently, a rat model of BPH produced by implanting fetal urogenital sinus (UGS) into adult rat ventral prostate was developed. Using this model, we found that genes associated with growth factors, cytokines and chemokines were up-regulated in the BPH specimens compared with those in normal prostate, suggesting that their multiple families act through paracrine signaling to stimulate prostate proliferation. In addition, we found that myofibroblasts differntiation played a significant role in prostate growth in BPH.
Genome-wide association studies can link multiple SNPs to drug response. More limited genetic variant studies have been performed within alpha1-AR subtypes SNPs within a biologic pathway implicated in BPH could improve predictive ability. We have found 9 potential candidate SNPs associated with the efficacy of alpha1-AR antagonists, although further study will be needed.
