Concurrently, diminished AOD values for both LFB staining (Fig. 3C-c–C-e) and immunohistochemical staining of CNPase (Fig. 3C-h–C-j) and MBP (Fig. 3C-m–C-o) were noted in the GDM+VPA group, signifying a heightened impact on myelin-specific proteins and lipids compared to the GDM group. The gene discussed is MBP; the disease is gestational diabetes.
