Figure Lengend Snippet: AZA / RES treatment improved mitochondrial condition and reduced ROS accumulation in ASC EMS . To investigate oxidative stress in cells, they were culture for 24 hours in control or experimental conditions and subjected to further analysis. MMP was measured using JC ‐1 probe by flow cytometry (A). MMP depolarization in ASC EMS was markedly reversed in ASC EMS II (B). Intracellular ROS level was stained with H2 DCFDA and detected by flow cytometry. Results were respectively shown in the histograms (A). AZA / RES treatment significantly reduced ROS production in ASC EMS (C). Antioxidative properties of cells were analyzed by spectrophotometric measurement of SOD activity (D). ASC EMS II displayed enhanced enzyme activity. Using RT ‐ PCR amount of miR‐24 was evaluated (E). TEM analysis showed ultrastructural changes in mitochondria morphology in ASC EMS and it reversal after AZA / RES treatment (F). Boxed regions were magnified and showed on the left side. Based on representative photographs, quantification of aberrant mitochondria was performed (G). Mitochondrial fission was examined using RT ‐ PCR for FIS (H) while mitophagy was established by measuring the expression of PINK (I) and PARKIN (J). Moreover, we established that AZA / RES diminished expression of Mief1 (K) and Mief2 (L). Furthermore, using western blot amount of MFF , MNF , PINK were investigated (M). In treated cells, AZA / RES mitigated both, mitochondrial division and mitophagy. Scale bars: 1 μm. Results expressed as mean ± SD .

Figure Lengend Snippet: AZA / RES diminish apoptosis and autophagy in ASC EMS by the inhibition of mitochondrial fission. In order to uncover the mechanism underlying AZA / RES beneficial effects on cells, they were cultured in control, AZA / RES and/or mitochondrial division inhibitor‐ MDIVI ‐, supplemented medium. After 24 hours of propagation cells were subjected to RT ‐ PCR , TEM and confocal analysis. Using RT ‐ PCR expression of p53 (A), p21 (B), p62 (C), PINK (D) and MFN (E) was analyzed. Mitochondrial dynamics and morphology of mitochondrial net were further visualized using TEM and confocal microscope (MitoRed staining) (F). Boxed regions were enlarged and presented below MitoRed staining to visualize shape of mitochondrial network. Obtained results indicated that beneficial effects of AZA / RES result from inhibition of mitochondrial fission and modulation of autophagy in treated cells. Scale bars: TEM : 5 μm, confocal: 20 μm.
