IL6 and gestational diabetes: When the expression of the six selected genes was compared between the GDM/SIRT1(↔) and NGT groups, only IL6 was significantly increased in the GDM/SIRT1(↔) group (FC = 1.88; p < 0.05); however, this increase was smaller than in the GDM/SIRT1(↑) group (FC = 2.29; p < 0.05).
