The expression of apoptosis related genes Bcl-2 and Bax protein in dysfunctional uterine bleeding

Abstract

To research the expression of apoptosis related genes Bcl-2 and Bax protein in dysfunctional uterine bleeding. Detecting the expression of Bcl-2 and Bax protein in 40 cases of endometrium tissue of dysfunctional uterine bleeding patients with immunohistochemistry antibiotics protein-peroxide emzyme (SP)methods. (1) The expression of Bcl-2 protein changes clearly and periodically in endometrium in normal cycle, the difference is obvious (P < 0.05). (2) The Bcl-2 protein develops with the hyperplasia in endometrium and the expression intensity is enhanced, the difference is obvious( P < 0.05). (3) The expression of Bax gene is masculine in endometrium in normal menstrual cycle. (4) The expression of Bax gene descends gradually with hyperplasia in uterine endometrium (P < 0.05). Apoptosis of endometrium cell is restrained from the excessive expression of Bcl-2 protein and deficient expression of Bax protein, so the uterine endometrium gets to hyperplasia or notypical hyperplasia.
