In 2018, Shang’s group [113] analyzed oxidative stress in GDM mothers and their newborns and found that the level of adiponectin in maternal plasma (GDM: ~0.5 μg/mL and non-GDM: ~0.8 μg/mL) was approximately four times lower than in cord plasma (GDM: ~2.7 μg/mL and non-GDM: ~2.6 μg/mL), but adiponectin expression in the placental tissue was not detected. The gene discussed is ADIPOQ; the disease is gestational diabetes.
