(A) qPCR analysis of expression of transporter genes in MHC-Cre vs. KLF15-cKO under fed vs. 48 hour fasting conditions. *P<0.05 vs. Cre Fed, **P<0.05 vs. CKO Fed, # P<0.05 vs. Cre Fast. Values normalized to Ppib. (B) Slc25a20 expression (qPCR) in MHC-Cre vs. KLF15-cKO under fed vs. 48 hour fasting conditions. *P<0.05 vs. Cre Fed, **P<0.05 vs. CKO Fed, # P<0.05 vs. Cre Fast. Values normalized to Ppib. (C) Western blot analysis of CACT levels in MHC-Cre vs KLF15-cKO under fed and 48 hour fasting conditions. α-tubulin used as loading control. (D) Quantification of data in C (n = 3 per group). Two-tailed Student's t-test for unpaired data was used. *P<0.05. (E) Left ventricular fractional shortening from echocardiography performed in control (MHC-Cre) vs. KLF15-cKO under fed vs. 48 hours fasting conditions following 10 weeks of short-chain fatty acid diet, (n = 10). (F) Representative echocardiography image from MHC-Cre vs. KLF15-cKO following 48 hours fasting and 10 weeks of short-chain fatty acid diet. (G) Tabular representation of echocardiography data in MHC-Cre vs. KLF15-cKO under fed vs. 48 hour fasting conditions following 10 weeks of short-chain fatty acid diet.
