DLX3 and preeclampsia: We obtained placentae from a clinically well-specified group of patients with preeclampsia and gestationally matched control pregnancies in order to evaluate the expression of homeobox gene DLX3 by immunohistochemical staining, real-time PCR, and Western immunoblotting and determine the function of DLX3 utilizing lentivirus transfection in HTR-8/SVneo cells.
