doi: 10.1096/fj.202402703R
Figure Lengend Snippet: Smyd2 tecKO Mitigates kidney injury in cisplatin‐induced CKD mice and suppresses ECM protein upregulation. (A–C) Immunofluorescence and Western blot analysis of SMYD2 expression and localization in renal tissues of Smyd2 tecKO mice, with β‐Actin as a loading control (scale bar: 50 μm; N = 3). (D) Schematic of cisplatin‐induced CKD model in Smyd2 tecKO mice. (E–G) Blood urea nitrogen (BUN), serum creatinine (Scr), and proteinuria levels in cisplatin‐treated Smyd2 tecKO mice and Smyd2 fl/fl mice ( n = 5). (H) H&E, Masson, and PAS staining of kidney sections. Scale bar: 10 μm. (I, J) Western blot analysis of renal ECM proteins (α‐SMA, fibronectin, collagen I) in cisplatin‐treated groups ( n = 3). * p < 0.05, ** p < 0.01, *** p < 0.001.
