RARRES2 and gestational diabetes: Barker and coworkers [146] assessed the chemerin levels in maternal and cord samples in relation to the presence of GDM and maternal obesity and determined that neither maternal obesity nor gestational diabetes influenced the plasma chemerin level (125.7 ± 7.4 ng/mL for lean; 115.1 ± 5.9 ng/mL for overweight; and 128.3 ± 6.6 ng/mL for obese mothers, respectively, and 117.6 ± 3.5 ng/mL for GDM and 124.2 ± 4.0 ng/mL for non-GDM mothers, respectively).
