WNT2 and congenital rubella syndrome: Under stress condition, overexpression of Wnt2 or Wnt3 blocked the CRS-induced decrease in BrdU+NeuN+ cells compared with the CRS-Lenti-GFP group (Figure 3i; CRS-Lenti-Wnt2, P=0.010; CRS-Lenti-Wnt3, P=0.015), which suggested that overexpression of Wnt2 or Wnt3 rescued CRS-induced hippocampal neurogenesis deficits.
