Additionally, a recent study investigating the effect of the GLP-1R agonist liraglutide on obesity-induced chronic kidney injury in obese rats showed that the agonist significantly reduced the lipid content and, concomitantly, the expression level of FABP1 protein in the obese kidney, relative to untreated rats58. This evidence concerns the gene GLP1R and obesity due to melanocortin 4 receptor deficiency.
