Análise do polimorfismo Mspl do gene CYP1A1m1 (Citocromo P450) em mulheres com endometriose

Abstract

Endometriosis is a disease that affects between 10 and 15% of women of reproductive age. Characterized by the presence of tissue resembling the endometrium similar to the uterine cavity outside the uterus, although some definitions specify that the ectopic tissue functional and sensitive to the action of hormones and their etiopathogenic mechanisms probably involve immunological abnormalities. The degree of involvement of endometriosis is based on the system proposed by the American Society for Reproductive Medicine (1985), based on the findings of laparoscopy. It is observed in the last 10 years, an increasing tendency to use a set of markers to detect changes induced by xenobiotics. Several genetic polymorphisms have been cited for the CYP1A1 gene, indicating a lack of functional protein that can cause an increase or a decrease in metabolic activity. The CYP1A1 gene encode the phase I enzymes involved in detoxification of estrogen metabolism, encodes an isoenzyme that catalyzes the oxidation of polycyclic aromatic hydrocarbons (PAHs) in phenolic compounds and epoxides. Mapped and located on the long arm of chromosome 15 (15q22-24). The aim of this study was to analyze the gene polymorphism frequency Mspl CYP1A1m1 with endometriosis. We analyzed 52 samples of peripheral blood of with endometriosis documented by laparoscopy (FÉRTILE) aged 25 to 35 women and 42 samples from women without endometriosis aged 25 to 57 years (control group). Molecular analysis by PCR (polymerase chain reaction). There was a statistically significant association (P = 0.039) between endometriosis and CYP1A1m1 polymorphic allele in women with endometriosis (32.70%) and compared with the control group 14,29%. We conclude that the gene polymorphism CYP1A1m1 correlates with endometriosis and polymorphisms are W1/m1candcm1/m1 morecfrequentcincpatientscwithcinfertilityandcwithvmorebseverebclinical bpicturebofbendometriosis.
