Project description:To characterize the molecular features of clinical (Hormone-Refractory Prostate Cancers) HRPCs, we generated the precise gene-expression profiles of 25 clinical HRPCs and 10 hormone-sensitive prostate cancers (HSPCs) by genome-wide cDNA microarrays combining with laser microbeam microdisection. Keywords: disease status analysis

Project description:Docetaxel is the standard first line therapy for hormone-refractory prostate cancer patients. Here we generated models of Docetaxel resistance in prostate cancer cells to study the molecular pathways that drive the acquisition of resistance to this therapy. We used microarrays to detail the global program of gene expression underlying the acquisition of Docetaxel resistance in prostate cancer cells. Parental Docetaxel-sensitive prostate cancer cell lines (DU145 and 22Rv1) and selected Docetaxel-resistant cells (DU145-DR and 22Rv1-DR) were harvested for RNA extraction and hybridization on Affymetrix microarrays. Samples were analyzed in triplicates in order to increase the resolution of expression profiles.

Project description:Purpose: Androgen-deprivation therapy is the standard treatment for prostate cancer but fails in hormone-refractory prostate cancer. The anti-inflammatory plant Wedelia chinensis is rich in luteolin, apigenin, and wedelolactone that act synergistically to suppress androgen receptor activity in prostate cancer. Here, we evaluated the systemic antitumor effects of a standardized and effect-optimized Wedelia chinensis herbal extract (WCE) on hormone-refractory prostate cancer. Methods: Hormone-refractory PC-3 orthotopic tumor mouse models were orally administered with WCE. The tumor transcriptomes were studied using RNA sequencing and Ingenuity Pathway Analysis to identify the molecular mechanisms. Results: WCE significantly attenuated tumor growth and metastasis in orthotopic PC-3 xenografts. Transcriptomic analysis of genome-wide gene expression in the tumors revealed that WCE suppressed the expression of HIF1α, IKKα/β phosphorylation, and the downstream cytokines/chemokines. Conclusions: A standardized preparation of Wedelia chinensis improved prostate cancer therapy through repressing NFκB-mediated cytokine expression in tumor cells and modulating the inflammatory tumor microenvironment. These data suggest that WCE functions through immunomodulation and has potential application as an adjuvant agent for the treatment of castration-resistant prostate cancer.

Project description:Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. To investigate the AR signaling, we performed RNA sequence analysis in AR positive prostate cancer cell line, LNCaP. In addition, we used hormone-refractory prostate cancer model cells, Bicalutamide-resistant (BicR) to explore the differences of androgen signaling in prostate cancer progression.
