... pathways. PPAR-alpha worked in the artery wall by regulating the genes involved in the transport and metabolic breakdown of cholesterol, called LXRs. In contrast, the ability of PPAR-gamma to inhibit atherosclerosis was independent of LXR and, instead, induced expression of another protein called ATP-binding c...Choosing the kind of fat to avoid obesity
