Mangiferin ameliorates gestational diabetes mellitus-induced placental oxidative stress, inflammation and endoplasmic reticulum stress and improves fetal outcomes in mice.

Gestational diabetes mellitus (GDM) is a temporary form of diabetes during pregnancy, which causes maternal diabetic symptoms and abnormal fetal development, and influence the health of maternal-child in clinical practice. Mangiferin is a bioactive ingredient with anti-inflammation, anti-oxidation and anti-endoplasmic reticulum stress activities. In current study, the effects of mangiferin on GDM were evaluated. We reported that mangiferin greatly improved altered glucose and lipid profile, insulin tolerance, and reproductive outcomes of the GDM mice. Mangiferin ameliorated placental oxidative stress, inflammation and ER stress in GDM mice. Therefore, we demonstrated that mangiferin displayed protective effects on gestational diabetes mellitus symptoms by suppressing placental oxidative stress, inflammation and endoplasmic reticulum stress in GDM mice.
