Abstract

Castration-resistant metastatic prostate cancer (CRPC) is an incurable disease, a large number of studies have been looking for therapeutic alternatives based on the molecular pathways that act in this phase of the neoplasia. Alterations in the androgen receptor occur frequently in the progression of this neoplasia and the androgen receptor cofactors appear as attractive molecules, since these cofactors also play an important role in lipogenesis, metabolism, proliferation, apoptosis and cell cycle. It is believed that microRNAs may be involved in regulating the expression of these cofactors. Present study will seek to establish a hypercholesterolemia in vivo model in NOD.CB17-SCID mice with CPRC, where will be evaluated the expression profile of genes and proteins co-activating of the androgen receptor, p160 (SRC-1, SRC-2 and SRC-3), Histone Acetyl-transferase (p300 and CBP) and IL-6 and of its co-repressors such as Cytoskeletal Protein (ARA67) and Nuclear Receiver (SMRT/NCoR2). In this model, will be evaluated the effect of the administration of miR-137 and miR-17-5p in addition to the lipid profile of the animals and the administration of these same microRNAs will be evaluated in Prostate Cancer cell line (PC3).
