Abstract

Endometriosis is a female disease with high incidence and unknown causes because of the presence of endometrial tissue outside of the uterine wall. Glutathione S- transferase (GSTs) is a key enzyme in phase I and II that catalyzes the conjugation of glutathione to genotoxic compounds. Glutathione S- transferase M1 (GSTM1) is a versatile enzyme that plays an important role in detoxification of carcinogenic metabolites. The aim of this study was to evaluate serum levels GSTM1 in patients with endometriosis. In this study, blood samples from 20 women with endometriosis and 20 healthy women were collected. The final concentration of protein in the blood of patients (TPC) and GSTM1 in serum by using "biuret" and enzyme-linked immunosorbent assay "(ELISA) were measured. It was shown that the level of total protein concentration all samples are within the normal range and no significant changes between the two groups were seen. Although significant reduction in serum levels GSTM1 was observed in patients with Endometriosis compared to the control group (P = 0.002). The results of this study showed that GSTM1 is involved pathophysiology of endometriosis.
