TGFB1 and preeclampsia: This finding aligns with documentation in various other studies (Table 2).Peraçoli MT et al. determined the plasma concentration of TGF-β1 in normal pregnancy and preeclampsia women in the third trimester and found that active TGF-β1 levels were significantly higher in preeclamptic women (10.41 ± 2.07 ng/mL) compared with normal pregnant women (7.01 ± 3.29 ng/mL) [18].
