SIRT1 and gestational diabetes: As expected, the leukocyte SIRT1 expression was significantly higher in the GDM/SIRT1(↑) group than the GDM/SIRT1(↔) and NGT groups (p < 0.05), with a 3.23- and 3.07-fold up-regulation, respectively; however, the level was comparable between the GDM/SIRT1(↔) and NGT groups (p > 0.05) (Table 1, Figure 1).
