WebCertain flavonoids inhibit glucose uptake in cultured cells. In this report, we show that the grapefruit flavanone naringenin inhibited insulin-stimulated glucose uptake in proliferating and growth-arrested MCF-7 breast cancer cells. Our findings indicate that naringenin inhibits the activity of phosphoinositide 3-kinase (PI3K), a key regulator of insulin-induced … WebCarbohydrate metabolism and mediators of metabolic reprogramming. Cancer cells must acquire a greater amount of nutrients, especially glucose. One of the mediators is HIF-1, which increases glucose uptake through the induction of GLUT-1, GLUT-4 and GLUT-1; simultaneosly, it can also be stimulated by TGF-β through the PI3K/AKT/mTOR pathway. ct611se
