Abstract

Prostate cancer (PCa) is the second most frequent and the second highest rate of morbidity and mortality among men. Studies highlight the role of obesity and the extracellular matrix in the progression of PCa to the more aggressive, metastatic and resistant state to antiandrogenic, chemotherapeutic and radiotherapeutic therapies. Transcriptome analyzes of transgenic mouse models for prostate cancer have revealed changes in the expression of hundreds of genes, which have been confirmed in gene expression databases for human prostate tumors. In this project, we will characterize in more detail, in two subprojects, alterations in genes related to Adiponectin hormone pathway and its receptors ADIPOR1 and ADIPOR2; and the participation of extracellular matrix protein type X collagen, gene COL10A1. For this, we intend: 1) to characterize the pattern of gene and protein expression of these pathway components in human prostate tumor samples and associate with clinical data of the patients by data mining in public databases and in our own group of patients by immunohistochemistry and qPCR. 2) To evaluate the effects of Adiporon (agonist of Adiponectin receptors) administration on prostate tumor progression of TRAMP mouse model; 3) To evaluate the effects of high fat diet on growth, maturation, aging and lesions onset in the adiponectin knockout mice; 4) to perform in vitro functional studies to characterize the pattern of gene and protein expression of these pathways by normal and prostatic tumor cells (PNT-2, LNCaP, PC3, DU145) under different culture conditions, such as: exposure to agonists, inhibitors, to type X collagen protein or after transcription silencing of the mRNA for some components of these pathways; associated with viability, proliferation, migration and cell invasion assays and gene expression analysis. These results will contribute to a better understanding of the participation of these pathways in prostate cancer, to reveal data for better patient prognosis stratification and potential therapeutic targets.
