Expression of Six bHLH Superfamily Members in Mouse Uterus During Early Pregnancy

bHLH transcript factor superfamily members involve in various bio-events in mice. According to existing researches, there are six members of bHLH superfamily likely to participate in the uterine development during early pregnancy in mice. Expression of six members of bHLH superfamily Hes6, Tcf23, Twist1, Twist2, Mitf and Tead4 in mouse uterus in early pregnancy was detected by RT-qPCR. All the six genes were expressed in early pregnancy mouse uterus, and expression pattern of each one was different from others. In situ hybridization results showed that Tead4 was expressed in decidual tissues of the 8th day pregnancy mouse. Tead4 might be involved in the regulation of embryo implantation in mice.
