Figure Lengend Snippet: Figure 3. Increased oxidative stress and NLRP3 inflammasome pathways are ameliorated by 1,25(OH)2D3 treatment in DOX‑induced cardiomyopathy in mice. (A) AC16 cells treated with different concentrations of 1,25(OH)2D3 (0, 25, 50, 100, 200 and 400 nM) for 24 h. Cell viability was measured using CCK‑8 assay (n=3). (B) AC16 cells were treated with 1 µM DOX and different concentrations of 1,25(OH)2D3 (0, 25, 50, 100 and 200 nM) for 24 h. Cell viability was measured using CCK‑8 assay (n=3). ****P<0.0001 vs. Control group; #P<0.05 and ####P<0.0001 vs. DOX‑only group; &&&P<0.001 vs. DOX + 25 nM 1,25(OH)2D3‑treated group; @@P<0.01 vs. DOX + 50 nM 1,25(OH)2D3‑treated group.

Levels of (E) MDA, (F) T‑SOD and (G) GSH‑Px in cardiac tissue 4 weeks after the first injection of DOX (n=5). (H) Western blotting images of cardiac tissue extracts analyzing protein expression of SOD1, SOD2, Nrf2 and KEAP1. GAPDH was used as the loading control. (I) Semi‑quantification of protein expression levels of SOD1, SOD2, Nrf2 and KEAP1. Protein expression levels relative to the Sham group were assessed by densitometric analysis (n=3). (J) Western blotting images of cardiac tissue extracts analyzing protein expression of NLRP3, ASC and Caspase‑1. GAPDH was used as the loading control. (K) Semi‑quantification of protein expression levels NLRP3, ASC and Caspase‑1. Protein expression levels relative to the Sham group were assessed by densi‑ tometric analysis (n=3). *P<0.05, **P<0.01, ***P<0.001 and ****P<0.0001 vs. Sham; #P<0.05, ##P<0.01, ###P<0.001 and ####P<0.001 vs. DOX. DOX, doxorubicin hydrochloride; CCK‑8, Cell Counting Kit‑8; ns, no significant difference; DCFH‑DA, 2',7'‑dichlorofluorescin diacetate; MDA, malondialdehyde; T, total; GSH‑Px, glutathione peroxidase; SOD, superoxide dismutase; Nrf2, nuclear erythroid 2‑related factor 2; KEAP1, Kelch‑like ECH‑associated protein 1; ASC, caspase recruitment domain; NLRP3, nod‑like receptor family pyrin domain‑containing 3 inflammasome.

doi: 10.1155/2018/2615372

Figure Lengend Snippet: SOD1 and SOD2 protein expression. Western blotting analysis of superoxide enzymes cytosolic type 1 and mitochondrial type 2 was performed on young and elderly myoblasts and myotubes. β -Actin content was used for normalization. Panels (a), (b), (c), and (d) show SOD1 and SOD2 densitometric analysis of Western blots performed on three young and three old samples expressed as mean ± SEM. Representative patterns of SOD1, SOD2, and β -actin (as loading control) expression in young and elderly myoblasts and myotubes are shown in panels (e) and (f). The bands were taken from two nonadjacent lanes originating from exactly the same gel and blot with exactly the same exposure time, but spliced together indicated with double-dotted lines. Moreover, we performed no change in contrast ( ∗ p ≤ 0.05).
