Redox-dependent processes of neoplasm in the cervical cancer progression

The parameters of system «lipid peroxidation – antioxidants» and the bcl-2, Ki-67 expression in tumor tissue of patients with cervical cancer at different stages of cancer was studied. It is shown that in neoplasm of patients with common neoplastic process the accumulation of TBA-active products of lipid peroxidation, along with the depletion of antioxidant enzymes, a defense (SOD and catalase) as well as increased expression of bcl-2, Ki-67 in the parenchyma and stroma of the tumor tissue cervical cancer was observed.
