Etude du stress oxydatif dans l’hypertrophie bénigne de la prostate et mise en évidence de l’effet de la propolis contre le cancer de la prostate in vivo sur un modèle animal de rat Wistar et ex vivo sur les cellules LNCaP du cancer de la prostate hormono-sensibles

Abstract : BPH and prostate cancer are the two most prevalent prostatic diseases in elders. Understanding their etiology and pathogenesis is necessary in order to prevent them and to enhance both research and development of new therapeutic agents. Our goal is to study the implication of oxidative stress in BPH and to study the effect of propolis extract on prostate cancer in vivo in Wistar rats and in vitro on LNCaP cells. We have shown that: 1) Oxidative stress acts as a promoter in the development of BPH, 2) Benzo(a)pyrene administered to Wistar rats induces the development of prostate cancer, 3) Propolis induces a decrease in proliferation, Ki-67 expression (-49%) and AhR expression in the Wistar rat, (4) Propolis has an antiproliferative effect on LNCaP cells via AR signaling blockade.
