Abstract
PURPOSE Evaluate the therapeutic effect of a tomato lipidic extract (STE) in combination with selenium (Se) on rats with prostatic hyperplasia (PH) and to observe its possible mechanisms of action and synergism versus finasteride. MATERIALS AND METHODS 54 male Wistar rats of nine weeks old were divided in Control (C), PH, Finasteride (F), STE, Se, F + STE, F + Se, STE + Se and F + STE + Se with testosterone enanthate (except C). After 4 weeks of treatment administration, prostate weight, bladder weight, diuresis, prooxidant and antioxidant activity, dihydrotestosterone (DHT), androgen receptor (AR) expression and anatomopathological analysis were determined. RESULTS STE + Se decreased prostate weight 53.8% versus 28% in F group, also STE + Se decreased significatively glandular hyperplasia, prooxidant activity, DHT and AR expression and increased diuresis and antioxidant activity versus finasteride which increased MDA in prostate. CONCLUSIONS These results demonstrate a greater therapeutic and beneficial effect of tomato lipidic extract in combination with Se in young rats with PH with respect to finasteride without increase prooxidant activity.

Cell Rep 2017; 17:966-976.

Abstract
Although well characterized as a transcriptional activator that drives prostate cancer (PCa) growth, androgen receptor (AR) can function as a transcriptional repressor, and high-level androgens can suppress PCa proliferation. The molecular basis for this repression activity remains to be determined. Genes required for DNA replication are highly enriched among androgen-repressed genes, and AR is recruited to the majority of these genes, where it rapidly represses their transcription. This activity is enhanced in PCa cells expressing high AR levels and is mediated by recruitment of hypophosphorylated retinoblastoma protein (Rb). Significantly, AR also indirectly increases the expression of DNA replication genes through stimulatory effects on other metabolic genes with subsequent CDK activation and Rb hyperphosphorylation. In castration-resistant PCa cells, which are dependent on high-level AR expression, this anti-proliferative repression function might be exploited through treatment with androgen in combination with agents that suppress AR-driven metabolic functions or cell cycle progression.

Anti-proliferative activities of finasteride in benign prostate epithelial cells require stromal fibroblasts and c-Jun gene. PLoS One 2017; 12:e0172233. [PMID: 28196103 PMCID: PMC5308847 DOI: 10.1371/journal.pone.0172233] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2016] [Accepted: 02/01/2017] [Indexed: 12/15/2022] Open
Abstract
This study aimed to identify the role of mouse fibroblast-mediated c-Jun and IGF-1 signaling in the therapeutic effect of finasteride on benign prostatic epithelial cells. BPH-1 cells, alone or with fibroblasts (c-Jun+/+ or c-Jun-/-), were implanted subcutaneously in male nude mice who were then treated with finasteride. The degrees of cell proliferation, apoptosis, and sizes of the xenografts were determined. BPH-1 cells were grown alone or co-cultured with mouse fibroblasts in the presence of finasteride and the level of IGF-1 secreted into the medium by the fibroblasts was determined. The proliferation-associated signaling pathway in BPH-1 cells was also evaluated. Fibroblasts and c-Jun promoted xenograft growth, stimulated Ki-67 expression, and inhibited BPH-1 apoptosis. Finasteride did not induce the shrinkage of xenografts in the combined-grafted groups despite repressing Ki-67 expression and inducing cell apoptosis. The addition of c-Jun-/- fibroblasts did not promote xenograft growth. In the absence of c-Jun and fibroblasts, finasteride did not alter xenograft growth, Ki-67 expression, or cell apoptosis. The in vitro results demonstrated that when BPH-1 cells were grown in monoculture, treatment with finasteride did not induce cell death and stimulated the expression of pro-proliferative signaling molecules, while in the presence of fibroblasts containing c-Jun, finasteride treatment repressed epithelial cell proliferation, the level of IGF-1 in the medium, and the activation of downstream pro-proliferative signaling pathways. Taken together, our results suggest that fibroblasts, c-Jun, and IGF-1 play key roles in mediating stromal-epithelial interactions that are required for the therapeutic effects of finasteride in benign prostate epithelial cells.
