Examination of Bcl-2 and Bax Protein Levels for Determining the Apoptotic Changes in Placentas with Gestational Diabetes and Preeclampsia

Anti-apoptotic Bcl-2 and proapoptotic Bax genes are the most significant genes that are involved in the regulation of apoptosis. Abnormal apoptotic activity in preeclampsia and gestational diabetes is caused by dysregulation of these genes. In this study; we examined Bcl-2 and Bax protein expressions using immunohistochemical techniques in human placental tissue samples from cases of gestational diabetes (n: 20) and preeclampsia (n: 20). It was observed that Bax expression showed positive reaction compared to Bcl-2 expression so; Bax protein was thought to be an effective marker in determining apoptotic changes in placentas with gestational diabetes and preeclampsia
