Decreased β-catenin Expression in First Trimester Villi and Decidua of Patients with Recurrent Spontaneous Miscarriage

Abstract

Accumulating evidence suggests that Wnt/β-catenin pathways play an important role in  the  physiological  processes  of  endometrial  development  and  differentiation, preimplantation embryo development, and blastocyst implantation. The objective of the current study was to signify the association between Wnt/β-catenin signalling pathway and recurrent spontaneous miscarriage and examine the expression of β-catenin first- trimester villi and decidua in women with spontaneous miscarriage. A comparative cross-sectional  study was conducted in Saladin  General  Hospital  from the 1st of January to the 1st of October 2021. A convenient sample of 80 pregnant women was enrolled in the current study and consisted of group A (40 pregnant women who were presented with first or second miscarriage) and group B (40 pregnant women who were presented with recurrent spontaneous miscarriage). There was a significant association between decreased β-catenin and recurrent miscarriage as 77.5% of the women who presented with recurrent spontaneous miscarriage had decreased levels of β-catenin, while only 32.5% of those with first or second miscarriage had decreased levels of β- catenin. The results of the current study implied that β-catenin is a valuable biomarker for unexplained recurrent spontaneous miscarriage. The women who presented with recurrent spontaneous miscarriage had a decreased expression of β-catenin .
