The protein expression of Notch receptors 1-4 and its ligands Jag1 and 2 and Dll1 and 4, by Western blotting in placentas of patients with early-onset severe preeclampsia. The protein expression level of Notch2 in placentas from patients with early-onset severe preeclampsia was significantly lower than that in the normal-term placentas (P < .05), while the protein expression level of Notch3 in placentas of patients with early-onset severe preeclampsia was higher than that in the normal-term placentas (P < .01). *P < .05. The error bars represent the means ± standard deviation (SD). P indicates placentas from patients with early-onset severe preeclampsia; N, normal-term placentas.
