1 Effects of metformin and glibenclamide on insulin receptors in fibroblasts and tumor cells in vitro. Glyburide insulin Homo sapiens
2 The effects of the oral hypoglycemic agents metformin and glibenclamide on receptor binding of insulin and insulin-induced receptor down-regulation were studied in cultured normal human fibroblasts, human breast tumors (cell lines MCF-7 and T-47D) and a human colon tumor (cell line HCT-8) in order to identify differences in receptor regulation between normal and transformed cells. Glyburide insulin Homo sapiens

Glyburide insulin Homo sapiens
4 Glibenclamide (2 microM) and metformin (1-10 microM) induced a 13-28% reduction in insulin receptor down regulation in fibroblasts exposed to 1.7 x 10(-8)M-insulin, the loss of binding on exposure to insulin decreasing from 55% to 40-48%. Glyburide insulin Homo sapiens
