FABP1 and obesity due to melanocortin 4 receptor deficiency: Overexpression of murine FABP1 is associated with increased LCFA uptake and hepatic TG levels [25,26,27], while FABP1−/− mice exhibit decreased hepatic triglyceride content with altered FA uptake kinetics [12], with protection against diet-induced obesity and hepatic steatosis [14,28].
