In 2018, Shang’s group [113] analyzed the resistin level in women with GDM and their newborns in relation to oxidative stress and noted that the level of resistin in maternal blood (GDM: ~18.0 ng/mL and non-GDM: ~12.0 ng/mL) was higher than in cord plasma (GDM: ~14.0 ng/mL and non-GDM: ~12.0 ng/mL) and placenta (GDM: ~12.0 ng/mg placenta and non-GDM: ~9.0 ng/mg placenta). Here, RETN is linked to gestational diabetes.
