The expression of IGF2 in placenta also had a trend to be higher in GDM-NBW group compared to the NGT-NBW group (p = 0.085, Fig 1B), but the expression of IGF2 in cord blood was significantly lower in GDM-M group compared to NGT-M group (p = 0.012, Fig 2B). Here, IGF2 is linked to gestational diabetes.
