Nrf2 Is Involved in Hyperglycemia-induced Abnormal Lung Development through both Antioxidation-Dependent and Antioxidation-Independent Activation
Accumulating evidence has shown that hyperglycemia during pregnancy negatively affects lung development. However, the pathological mechanism of lung dysplasia caused by hyperglycemia remains unclear. In this study, we demonstrated the phenotypes of the impaired lung epithelial cell differentiation of mouse lungs in pregestational diabetes mellitus (PGDM) and gestational diabetes mellitus (GDM), and increased levels of oxidative stress and activation of the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathways occurred. Nrf2 deficiency during pregnancy led to the aforementioned similar and aggravated phenotypes of the poor saccular process as in diabetes, implying the Nrf2 signaling pathway played a very important role in both physiological and pathological conditions. Based on RNA sequencing and luciferase reporter gene analysis, we revealed that Nrf2 could regulate Wnt signaling by targeting Ctnnd2. In summary, we revealed the pathological mechanism of how diabetes affected late lung development during embryogenesis, especially elucidating the bilateral roles of Nrf2-mediated oxidative stress responses and Wnt signaling. This finding also indicated that Nrf2 could potentially be used in preventing or treating pulmonary anomalies induced by hyperglycemia during pregnancy.
