Results were suggestive of altered hPL dynamics in pregnancies affected by pre‐existing type 1 diabetes (T1DM), but, despite preclinical evidence for physiological roles in both insulin resistance and maternal beta cell adaptation to pregnancy, our meta‐analysis demonstrated no evidence of an association between absolute hPL concentrations and maternal GDM status (either in early or later pregnancy).7 Here, LGALS1 is linked to Insulin resistance.
