Thus, the aim of our study was to assess the expression of membrane fatty acid handling proteins (FAT/CD36, FABPpm, FATP-4) at the mRNA and protein level in the SAT and VAT of patients with obesity, as well as the expression of lipoprotein lipase (LPL), peroxisome proliferator-activated receptor γ (PPARγ), cytosolic FABP4 and FABP5. This evidence concerns the gene SLC27A4 and obesity disorder.
