NFKB1 and obesity due to melanocortin 4 receptor deficiency: Moreover, a number of metabolic-related pathways were screened, including the “NF-κB signaling pathway” and the “B-cell receptor signaling pathway.” KEGG pathway analysis suggests the possibility that Sal B exerts its weight reduction effect through the regulation of adipose metabolism via insulin resistance and IL-17 signaling in HFD induced-obesity mice.
