Article Title: Effect of His Bundle Pacing on Abnormal Myocardial Fatty Acid and Glucose Metabolism Induced by Right Ventricular Pacing
doi: 10.1161/JAHA.123.032386
Figure Lengend Snippet: In terms of regulatory proteins related to fatty acid metabolism, we checked the key proteins, such as CD36, CPT1, ACC1 and HSL. A , The expression of CD36 was higher in the RV pacing group than the sham control and His pacing groups. The expression of CPT1 ( B ) and p‐ACC1/ACC1 ( C ) did not differ among the 3 groups. D , The expression of HSL was significantly lower in the RV pacing group compared with the sham control and His pacing groups. E , We also evaluated the inhibitory form of HSL ( p565 HSL), and the expression of p565 HSL/HSL was significantly lower in the RV pacing group compared with the sham control and His pacing groups. * P <0.05; ** P <0.01. ACC1 indicates acetyl‐CoA carboxylase 1; CPT1, carnitine palmitoyltransferase I; HSL, hormone‐sensitive lipase; and p‐ACC1, phosphorylated acetyl‐CoA carboxylase 1.
Article Snippet: The primary antibodies against binding immunoglobulin protein (Bip), glucose transporter 4 (GLUT4), hormone‐sensitive lipase (HSL), pyruvate dehydrogenase (PDH), acetyl‐CoA carboxylase 1 (ACC1), phosphorylated ACC1 (Ser79), phosphorylated HSL (Ser565) (1:1000 dilution; Cell Signaling Technology, Danvers, MA), tumor necrosis factor‐α (TNFα; 1:200 dilution; Santa Cruz, TX), and carnitine palmitoyltransferase I (CPT1) (1:5000 dilution; Abcam, Cambridge, MA) were used to react with the blots at 4 °C overnight in 5% nonfat dry milk.
