Research Abstract

(1) We demonstrated the differential expression of estrogen receptor-related protein in prostate cancer. (2) We evaluated CYP3A4 expression in human prostrate cancer tissues. (3) We identified amyloid precursor protein and ARFGAP3 as a primary androgen targetandrogen target genes that are directly regulated by AR in LNCaP cells, by combining chromatin immunoprecipitation (ChIP) with tiling micro-arrays (ChIP-chip). (4) We identified Oct1 correlates with the poorer survival prognosis of the prostate cancer patients.
