Study on the expressions of PHD and HIF in placentas from normal pregnant women and patients with preeclampsia.

ABSTRACT:

Objective

To investigate the relationship between oxygen sensitivity of trophoblast and hypoxia in preeclamptic placenta by the study on the expressions of hypoxia-inducible factor prolyl 4-hydroxylase (PHD) and hypoxia-inducible factor (HIF) in placentas from normal pregnant women and patients with pre-eclampsia.

Methods

Subjects were chosen from the in-patients or the out-patients from May 2003 to May 2004. They were divided into 5 groups: early pregnancy group (EP), 13 cases; middle pregnancy group (MP), 9 cases; late pregnancy group (LP, or control group), 12 cases; preeclampsia (PE) group, 20 cases; gestational hypertension group (GH), 10 cases. The mRNA expressions of PHD-1 and -2 and -3 in placentas from all the subjects were assessed by in situ hybridization and Real
