Abstract

Objective: This study aimed to evaluate the immunohistochemical expression of APAF-1 and E-cadherin in placental tissues of smoking women with premature rupture of membranes (PROM).

Materials and Methods: Placental samples obtained from smoking and non-smoking women diagnosed with PROM and from healthy controls were examined immunohistochemically for APAF-1 and E-cadherin expression.

Results: Increased APAF-1 expression and decreased E-cadherin expression were observed in placentas of smoking women with PROM compared to controls.

Conclusion: Smoking may contribute to PROM by enhancing apoptotic activity and disrupting placental cell–cell adhesion.
