In addition to STC1, PE as well as GDM placentae were characterized by significantly higher gene expression of LYPD6 (encoding LY6/PLAUR domain containing 6) and CCNG2 (Cyclin-G2) (Table 3), confirmed by the stronger staining intensity of LYPD6 and CCNG2 antibodies on PE and GDM placental sections in performed IHC experiments (Figure 6, Figure S5, Figure S6). This evidence concerns the gene CCNG2 and gestational diabetes.
