Figure Lengend Snippet: KB1541 ameliorates senescence phenotypes. ( A ) Electron microscopy analysis revealed that DMSO-treated senescent fibroblasts exhibited less cristae wrinkle folds (blue arrow), whereas KB1541 treatment in senescent fibroblasts showed increased the number of cristae wrinkle folds (red arrow). Upper image: Scale bar 2 μm. Lower image: Scale bar 200 nm. ( B ) Comparison of cristae length between DMSO and KB1541-treated senescent fibroblasts. * P < 0.05, student t -test. Mean ± S.D., n = 6. ( C and D ) Flow cytometric analysis of ROS and mitochondrial mass using MitoSOX and MitoTracker green, respectively. ** P < 0.01, student t -test. Mean ± S.D., n = 3. Flow cytometry data of ROS and mitochondrial mass were presented in . ( E ) Flow cytometric analysis of autophagy level using Cyto–ID assay. ** P < 0.01, student t -test. Mean ± S.D., n = 3. Flow cytometric data of autophagy level were presented in . ( F ) Quantification of SA-β gal positive cells. ** P < 0.01, student t -test. Means ± S.D., n = 4. Scale bar 100 μm.
