Expression of fatty acid metabolism-related genes in the right atrial appendage of lean (white bars, n = 11), overweight/obese (gray bars, n = 11) and overweight/obese type 2 diabetic (black bars, n = 15) patients. mRNA levels are expressed as a % of the lean group ± SEM. * significant difference versus lean subjects. CPT1-M/L, carnityne palmitoyltransferase 1 muscle/liver isoform; FAT/CD36, fatty acid translocase/CD36; LPL, lipoprotein lipase, PDK4, pyruvate dehydrogenase kinase 4; ACO1, acyl-CoA oxidase 1.
