(A, B) Western blot images (A) and quantification (B) of Sodium-glucose cotransporter-2 (SGLT2) protein in AS podocytes transfected with Sglt2 siRNA (siSglt2) or nontargeting siRNA (siCtrl) for 72 hr. GAPDH was used as a sample loading control (n=3). (C,D) Bar graph analysis showing cytotoxicity (C) and apoptosis (D) normalized to viability (n=3) in siCtrl and siSGLT2 AS podocytes, with or without the treatment of empagliflozin (E), then compared with siCtrl. (E,F) Western blot images (E) and quantification (F) of CPT1A protein in siCtrl and siSglt2 AS podocytes, with or without the treatment of empagliflozin (n=3). (B), Two-tailed Student’s t-test, (C), (D), (F), One-Way ANOVA followed by Holm-Sidak’s multiple comparisons. *p < 0.05, ***p< 0.001.
