Fatty acid oxidation might increase mitochondrial acetyl-CoA levels and subsequently inactivate pyruvate dehydrogenase (PDH), which in turn, would increase intracellular citrate levels and inhibit phosphofructokinase 1 (PFK-1), and lead to the accumulation of intramyocellular glucose-6-phosphate (G6-P), which inhibits hexokinase activity and causes the accumulation of intramyocellular glucose and reduced glucose uptake. Diseases that exhibit dysregulated metabolism of carbohydrates and lipids. These cookies may also be used for advertising purposes by these third parties. In skeletal muscle, Akt promotes glucose uptake via the translocation of glucose transporter type 4 (GLUT4) storage vesicles (GSVs) to the plasma membrane, which is mediated by inactivation of GTPase-activating protein (GAP) AKT substrate of 160 kDa (AS160) and promotion of GTP-bound form of Ras-related C3 botulinum toxin substrate 1 (RAC1).

However, there is now evidence to support the view that insulin resistance is a heterogeneous disorder that may variably arise in a range of metabolic tissues and that the mechanism for this effect likely involves a unified insulin resistance pathway that affects a distal step in the insulin action pathway that is more closely linked to the terminal biological response.
