Abstract

Preeclampsia is a serious disorder of human pregnancy occurring after 20 weeks of gestation. It can be divided into subtypes of early onset (34 weeks). Presymptomatic detection to identify those at high risk is important for managing this disease. HtrA3, a serine protease with high expression in the developing placenta, exists in long (HtrA3-L) and short (HtrA3-S) isoforms. They are identical, except HtrA3-S lacks the C-terminal PDZ domain. We have previously shown by Western blot analysis that serum HtrA3 levels at the end of the first trimester are significantly higher in women who later develop preeclampsia than in controls. In this study, using highly specific HtrA3 monoclonal antibodies..
