Baicalin ameliorates renal injury by inhibiting the activation of PI3K/Akt/mTOR signaling pathway in DN rats. 30 SD rats are randomly divided into 5 groups (6 rats in each group) which are control group, DN group, 740Y-P group (3.5 mg/kg PI3K activator), Baicalin group (200 mg/kg baicalin), Baicalin + 740Y-P group (200 mg/kg baicalin + 3.5 mg/kg 740Y-PA), with 4 weeks of gavage. (a) qRT-PCR to detect the mRNA expressions of Nephrin, Podocin, and Desmin in the kidney tissues of rats in each group; (b) Western blot to detect the protein expressions of p-PI3K, PI3K, p-Akt, Akt, p-mTOR, and mTOR in the kidney tissues of rats in each group. *p < 0.05 vs DN group; &
p < 0.05 vs Baicalin group; and #
p < 0.05 vs DN + 740Y-P group.
