Figure Lengend Snippet: Impact of high fat feeding and voluntary exercise on left ventricle morphology in male mice. (A) Representative images of Picrosirius red staining for measurement of interstitial and perivascular fibrosis with 20× magnification. (B) Representative images for Hematoxylin and Eosin for measurement of cardiomyocyte width and area with 40× magnification. (C) Representative images of Oil red O staining for measurement of interstitial lipid deposition with 40× magnification. Quantitative analysis of percent area of (D) interstitial and (E) perivascular fibrosis expressed as fold change from sedentary chow group. Quantitative analysis of (F) cardiomyocyte width and (G) cardiomyocyte area. (H) Quantitative analysis of percent area of lipid deposition expressed as fold change from sedentary chow group left ventricle mRNA expression of fatty acid transporters (I) FABP3, (J) CD36, and hypertrophy markers (K) β-MHC and (L) ANP in male VET or sedentary mice fed an HFD or chow diet. Values were calculated relative to 18S housekeeper. 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. (D–H) n : 8–12 per group. (I–L) n : 8–9 per group. * p < 0.05, **** p < 0.0001. ANP = atrial natriuretic peptide; β-MHC = beta myosin heavy chain; CD36 = platelet glycoprotein 4; FABP3 = fatty acid-binding protein 3; HFD = high fat diet; Myh7 = moysin heavy chain 7; VET = voluntary exercise training.

Article Snippet: The following TaqMan assay gene transcripts were used: fatty acid-binding protein 3 (FABP3, Mm02342495_m1), platelet glycoprotein 4 (CD36, Mm00432403_m1), beta myosin heavy chain (β-MHC, Mm00600555_m1), atrial natriuretic peptide (ANP, Mm01255747_g1), OPA1 (Mm01349707_g1), DRP1 (Mm01342903_m1), robosomal18S (18S, Mm03928990_g1).

(B) Immunohistochemical staining of GLUT4 and CD36 in heart tissue ( n = 3). Photographs were taken at 400× using an electron microscope. (C) CD36 and GLUT4 protein levels ( n = 3). (D) Statistical analysis of western blotting results for the detection of protein expression. (E) GLUT4 immunofluorescence staining on the cell membrane ( n = 3). (F) CD36 immunofluorescence staining on the cell membrane ( n = 3). Photographs were captured at 400× using a confocal laser. ∗ P < 0.05; ∗∗ P < 0.01.

Article Snippet: Western blotting analysis was used to detect the expression levels of GLUT4, CD36, PI3K, Akt, and p-Akt using specific antibodies (GLUT4, 1:2000, Proteintech, 66846-1-Ig, China; CD36, 1:500, Wanleibio, WL02390, China; PI3K, 1:1000, Wanleibio, WL03380, China; Akt, 1:500, Wanleibio, WL0003b, China; p-Akt, 1:500, Wanleibio, WLP001a, China).
