SDC1 and preeclampsia: Similarly, the expression of SDC1, NPPB (natriuretic peptide B), GDF15 (growth differentiation factor 15), and ADAMTS6 (ADAM metallopeptidase with thrombospondin type 1 motif 6) all had a lower expression in our experimental exposures, and all are lower in preeclampsia (Junus et al., 2014; Chen et al., 2016; Gandley et al., 2016; Jiang et al., 2020).
