Chemerin, a novel adipokine, has been recently considered a regulator of adipogenesis, inflammation, and a missing link between obesity and vascular dysfunction.23 The gene expression of chemerin was significantly upregulated in the PVAT and mPVAT of A-NOS3 KO NCD mice and A-NOS3 KO HFD mice compared to their respective control mice (Figure 6A and B). Here, RARRES2 is linked to obesity disorder.
