Article Title: Influence of diet-induced obesity and voluntary exercise training on cardiac lipids and mitochondrial function in mice

doi: 10.1016/j.jshs.2025.101095

Figure Lengend Snippet: Voluntary exercise alters left ventricle gene and protein expression related to mitochondrial biogenesis and dynamics in high fat- and chow-fed mice. (A) Western blot analysis to assess purity of crude mitochondria isolation where left ventricle mitochondrial pellet expresses mitochondrial marker TOM70 and COXIV and supernatant expresses calnexin. Protein expression of (B) LCLAT1 and (C) MFN2 in left ventricle-isolated crude mitochondria and (D) LCLAT1, (E) PGC-1α, and (F) MFN2 in left ventricle tissue from male VET or sedentary mice fed an HFD or chow diet. Left ventricle mRNA expression of (G) OPA1 and (H) DRP1 in male VET or sedentary mice fed an HFD or chow diet. Values were calculated relative to 18S housekeeper. Calnexin and β-actin were used as internal controls of protein loading in left ventricle samples and COXIV as internal control of protein loading in crude mitochondria samples. Analysis was performed using two-way analysis of variance with Tukey’s post hoc test for multiple comparisons. Data are expressed as mean ± standard error of the mean. (B–C) n : 5–6 per group. (D–F) n = 7 per group. (G and H) n = 9 per group. CE = chow exercise; CS = chow sedentary; COXIV = cytochrome c oxidase subunit 4; DRP1 = dynamin-related protein 1; HE = high fat diet exercise; HFD = high fat diet; HS = high fat diet sedentary; LCLAT1 = lysocardiolipin acyltransferase 1; MFN2 = mitofusin-2; OPA1 = optic atrophy 1; PGC-1α = peroxisome proliferator-activated receptor gamma coactivator-1α; TOM70 = translocase of outer mitochondria membrane 70; VET = voluntary exercise training.

Article Snippet: Immunoblotting was performed with antibodies against lysocardiolipin acyltransferase 1(LCLAT1, PA5-25627; Thermo Fisher Scientific), PGC-1α (ab191838; Abcam, Cambridge, UK), MFN2 (PA5-118059; Thermo Fisher Scientific), ANP (sc-18811; Santa Cruz, Dallas, TX, USA), tumor necrosis factor alpha (TNFα, 3707; Cell Signaling, Danvers, MA, USA), phosphorylated adenosine monophosphate-activated protein kinase (AMPK, 2531; Cell Signaling), AMPKα (2532; Cell Signaling), Perilipin 5 (PA1-46215; Thermo Fisher Scientific), translocase of outer mitochondria membrane 70 (TOM70, 65675; Cell Signaling), cytochrome c oxidase subunit 4 (COXIV, 4844; Cell Signaling), and calnexin (208880; Merck, Rahway, NJ, USA).

Article Title: PDK1 elevation was induced by epigenetic modifications of KDM3A and METTL16 to mediate TKI resistance and cancer development

doi: 10.1016/j.gendis.2025.101947

Figure Lengend Snippet: PDK1 inhibitor JX06 and gefitinib synergistically induced cell apoptosis in gefitinib-resistant lung cancer cells. (A) The protein expression levels of PDK were reduced upon the treatment of PDK1 inhibitor JX06 in PC-9 and PC-9/G cells. (B) B2B and PC-9/G cells were treated with different concentrations of JX06 for 48 h. The cell viabilities were determined by CCK-8. (C – E) The synergy effect between JX06 and gefitinib was determined and analyzed with CompuSyn software. (F) The apoptosis rates were analyzed with flow cytometry after the combined treatment of gefitinib and JX06. (G) The TUNEL assay was performed with the indicated treatment in PC-9/G cells. (H) The cells treated as described were stained with the JC-1 probe and detected using a fluorescence microscope. Red fluorescence indicates the aggregation form of JC-1, showing increased mitochondrial membrane potential (ΔΨm). Green fluorescence indicates the monomeric form of JC-1, which indicates reduced mitochondrial membrane potential (ΔΨm). Data were statistically analyzed with Student’s t -test, and values were shown as mean ± standard deviation. ∗ P < 0.05 and ∗∗ P < 0.01.

Article Snippet: After different treatments for 48 h, the mitochondrial membrane potential of cells was detected with the enhanced mitochondrial membrane potential assay kit using JC-1 probe (Beyotime, Jiangsu, China), and the fluorescence was analyzed with a fluorescence microscope.
