MTOR and obesity due to melanocortin 4 receptor deficiency: Pathway and ontology analyses indicated that miR-15b, miR-26a, miR-301, miR-30b, and miR-30c participate in essential processes related to obesity, such as adipogenesis, fatty acid oxidation, mTOR (mechanistic target of rapamycin kinase) signaling, PPAR signaling, and Wnt signaling.
