Detection of WNT2B, WIF1 and β-catenin expression in preeclampsia by placenta tissue microarray

- The expression of Wnt2b and β-catenin mRNA were significantly decreased in sPE group than in control group.
- There was no significant difference in WIF-1 mRNA expression between the two groups.
- The expression of WNT2B and β-catenin protein were weaker in PE group compared with control group.
- The expression of WIF-1 protein was greater in PE group compared with control group.
