Npy, Agrp, and Ghrl gene expression in the greater omentum was not higher in HFD-rats than in SCD-rats, while plasma levels of AGRP, PMCH, and NPY were significantly elevated in HFD-rats and correlated to the gene expression in hypothalamus (Fig. 5c,d). The gene discussed is PMCH; the disease is Schnyder corneal dystrophy.
