Prostate cancer is the second major cause of death by cancer in Brazil. Currently, population screening methods and prognostic exams used in Brazil (PSA levels and digital rectal exam) are being questioned for their reliability, so the search for a genetic predictor of prostate cancer development risk and prognostic definition became imperative. Two microRNAs - miR-143 and miR-164a - were identified as tumor suppressors in the prostate cancer and recently variations were found on the promoter region of these miRNAs (rs4705342; rs2910164). The objective of our study is to identify the role of these variants on the development and prognostic of prostate cancer. DNA samples from 200 patients (100 patients diagnosed with prostate cancer and 100 patients without prostate cancer, as a control group) will be used. The identification of the polymorphisms will be perform through real-time PCR.
