In agreement with the literature, TNF-α is a central mediator of obesity-related metaflammation, since it promotes insulin resistance in the liver and skeletal muscle, impairs insulin signaling in adipocytes, increases lipolysis and free fatty acid flux to the liver, and contributes to endothelial activation and vascular dysfunction (Wu and Ballantyne, 2020). The gene discussed is TNF; the disease is obesity disorder.
