“…Recently, the role of leptin stimulating IR and the inhibitory role of adiponectin have been emphasized [ 45 , 46 , 47 , 48 , 49 , 50 ]. The pathogenesis of GDM also takes into account the participation of less known molecules such as galectins, growth differentiation factor-15, chemerin, omentin-1, osteocalcin, resistin, visfatin, vaspin, irisin, apelin, Fatty Acid-Binding Protein 4 (FABP4), fibroblast growth factor 21, lipocalin-2, fetuin-A and zonulin [ 43 , 44 , 46 , 51 , 52 , 53 , 54 , 55 ]. IR is seen in GDM patients, as well as in impaired insulin secretion due to a defect in pancreatic-cell function [ 33 , 37 , 56 ].…”
