Abstract
Objective: Gestational diabetes mellitus (GDM) is a frequently occurring complication during pregnancy and has adverse effects on both mother and offspring. β-Cell dysfunction and inflammation play important roles in GDM pathogenesis. Cornuside (CNS) is an iridoid glycoside that exhibits anti-inflammation activities. In the present study, we explored the effects of CNS on β-cell and GDM. Design: MIN6 β-cell line cells were treated with varying concentrations of CNS. The content and secretion of insulin were measured. Methods: The expression of Pdx1, Rac1, Piezo, and NeuroD1 and cell proliferation in CNS-treated MIN6 cells were detected. CNS was administered to GDM mice, and the symptoms of GDM, expression of IL-6 and TNF-α, and activation of NF-κB in GDM mice were measured. Results: CNS promoted cell proliferation of MIN6 cells, enhanced insulin content and secretion, and expression of Pdx1, Rac1, Piezo, and NeuroD1 in MIN6 cells. CNS alleviated symptoms of GDM mice and decreased serum levels of IL-6 and TNF-α in GDM mice. CNS suppressed the expression of IL-6 and TNF-α, as well as the activation of NF-κB in the placenta of GDM mice. Conclusion: CNS ameliorates GDM symptoms by suppressing inflammation and enhancing β-cell functions.
