Whereas densitometric analysis showed that placental LpPLA2 levels were increased in GDM (Fig. 7b, p = 0.04), oxPL protein modification was significantly reduced in GDM placental tissue (Fig. 7c, p < 0.001), suggesting an inverse association between LpPLA2 and its substrate; Pearson correlation, however was non-significant (r = −0.36, p = 0.09, data not shown). This evidence concerns the gene PLA2G7 and gestational diabetes.
