Glucose uptake capacity was not significantly changed after glucosamine and high glucose with high insulin induction and was reduced after palmitic acid induction. After high insulin stimulation, p-AKT/AKT levels were elevated in glucosamine and high glucose with high insulin induction and did not change significantly in palmitic acid induction. G6pase, PC, and PCK1 were elevated after glucosamine and palmitic acid stimulation, and only PCK1 was elevated after high glucose with high insulin stimulation. The transcriptomes of cells induced by the three methods differed widely.Conclusion: Treatment with 0.2 mM palmitic acid for 24 h is a simple and stable method to induce insulin resistance in HepG2 cells.Keywords: HepG2 cells, insulin resistance model, palmitic acid |
