EPIDEMIOLOGICAL ANALYSIS AND INVESTIGATION OF +114G/T POLYMORPHISM IN THE GENE IL-2 IN PATIENTS WITH BREAST CANCER IN THE STATE OF MATO GROSSO
Keywords:
Breast Cancer, Genetic Polymorphism, InterleukinAbstract
Objective: This study aimed to determine the relationship between the rs2069763 polymorphism of the Interleukin-2 (IL-2) gene and the development of breast cancer (BC) in women in the state of Mato Grosso. Methods: This is an observational epidemiological study of case-control based on a bank of samples with 254 patients and 243 control women. The patients were subjected to anamnesis and collection of peripheral blood after their permission. The collecting of peripheral blood was carried out and was used for DNA extraction, followed by a genotyping process by Polymerase Chain Reaction-Restriction Fragment Length Polymorfism (PCR-RFLP) and polyacrylamide gel electrophoresis 8%. Results: The frequency of genotypes between cases and controls was 19.5% for the TT genotype; 44.2% and 32.1% for TG and GG, respectively. It was found, in samples of patients, a frequency of 14.9% for the TT genotype, 77.2% and 31.8% for TG and GG, respectively. In the controls, it was observed frequency of 24.1% for the TT genotype, 41.5% and 30.4% for TG and GG, respectively. Conclusions: The present study showed a higher incidence of polymorphism +114G/T in the control sample, suggesting a protective effect for the BC in the sample of women from Mato Grosso.
