In our study, as we expected, the induction of obesity by feeding rats a HFD significantly increased the expression of all examined LCFAs transporters (CD36, FABPpm, FATP-1, and FATP-4) in the red gastrocnemius muscle, while in the white skeletal muscle only expression of FABPpm and FATP-1 was enhanced. The gene discussed is SLC27A1; the disease is obesity disorder.
