Representative images of BODIPY stained RV sections. ( B ) Quantification of the cardiomyocyte fatty acid transporter, CD36 was lower in the db/db RV compared to the WT. ( C ) CD36 quantification by western blot showed no difference in the db/db RV. Representative western blots. ( D ) Membrane localization of CD36 showed downregulation in db/db RV. ( E ) Gene expression of FATP6 was upregulated in the db/db RV. ( F ) Protein expression by western blot showed higher FATP6 expression in the db/db RV. Representative western blots of FATP6 and caveolin. ( G ) Protein localization of FATP6 at the membrane was higher in the db/db RV compared to WT.

    RV remodeling in 8–10 week old db/db mice. ( A ) RV weight normalized to tibia length (TL) was higher compared to WT. ( B ) RV anterior wall (RVAW) thickness was higher in diastole in the db/db mice compared to the WT and trended towards significance during systole. ( C ) RV myocyte cross-sectional area (CSA) remained the same in the db/db RV, n = 20. Representative images of lectin staining. ( D ) Quantification of fibrosis by picrosirius red staining showed higher collagen in the db/db RV compared to WT. Representative images of PSR staining. ( F ) Quantification of lipid accumulation by oil red O staining showed higher lipid accumulation in the db/db RV compared to the WT. Representative images of oil red O staining. * p < 0.05 by Student’s t-test. For oil red O and picrosirius red staining, n = 3 with at least three views quantified per image. Scale bar: 50 µm
