Abstract

Schizophrenia is a multifactorial disease resulting from genetic disorders and unfavorable conditions of embryonic development and later life. The study revealed a pronounced negative correlation between markers of DNA damage in blood lymphocytes (oxidation marker 8-oxodG, double-strand break marker γH2AX) and the repeat content - satellite III subfraction (located in pericentromeric heterochromatin 1q12) in a sample of patients with schizophrenia in the acute stage (N = 97). The low content of the f-SatIII repeat in the DNA of leukocytes of patients can be considered as a potential marker of the level of both chronic oxidative stress and DNA damage in schizophrenia.
