Abstract

Insulin and IGF-I binding to neuroblastoma cells (SK-N-MC) was increased by 13% and 7% respectively following a 24 hr. incubation with the sulphonylurea glyburide. This increase in binding was associated with increased steady-state levels of insulin receptor and IGF-I receptor mRNA levels. Though insulin and IGF-I both stimulate glucose uptake into these cells, the increased binding following glyburide treatment was not associated with any change in glucose uptake.
