High mobility group box 1 protein polymorphism affects susceptibility to recurrent pregnancy loss by up-regulating gene expression in chorionic villi

摘要

Inflammation in chorionic villi is involved in the development of recurrent pregnancy loss (RPL). High mobility group box 1 protein (HMGB1) plays critical roles in inflammation and expression of the protein can be found in chorionic villi. The purpose of the study was to investigate the association between HMGB1 genetic polymorphisms and susceptibility to RPL and to examine the mechanism underlying this correlation.
