Maternal separation affects anxiety-like behavior beginning in adolescence and continuing through adulthood and related to Dnmt3a expression

Abstract

Most anxiety disorders begin in adolescence and continue through adulthood, and research on adolescent anxiety’s pathogenesis and treatment options is insufficient. In this research, our results show that maternal separation can successfully induce anxiety-like behavior in adolescent mice that continues through adulthood, further accompanied by abnormal expression of Dnmt3a, which provides an experimental basis for further development of anxiety/depression treatment programs more suitable for adolescence.
