Oxiditive Stress biomarkers levels in blood sample of Iraqi Breast cancer patients

Abstract

Background: Breast cancer is a malignant tumor arising from epithelial cells of glandular lacteferons ducts or terminal ductilobular unit (TDLM) of the breast which is affected by the oxidative stress and the defensive mechanisms against it. Objective: to reveal the correlation between the levels of superoxide dismutase (CuZn SOD), glutathione peroxidase (GSH-Px), glutathione reductase (GR), reduced glutathione (GSH) and sulfhydryl groups (SH) with breast cancer with/without metast. Methods: A case control study was performed on 30 female patients with metastasized breast cancer, 30 female patients with non- metastasized breast cancer and 30 female patients with benign breast tumor. All patients were recruited from Al-Karama teaching hospital at Wasit city in Iraq, for the period from October 2021 to February 2022. Results: The levels of GSH-PX, GR, GSH, and sulfhydral groups were significantly reduced in breast cancer patients in comparison with healthy controls whereas SOD levels were upregulated in breast cancer patients in comparison with healthy controls subjected to the current study. Conclusions: It is concluded that the activities of superoxide dismutase (CuZn SOD), glutathione peroxidase (GSH-Px), glutathione reductase (GR), as well as concentrations of reduced glutathione (GSH) and sulfhydryl groups (SH) have a significant impact on the pathogenisis and progression of breast cancer.
