Abstract
Structural modification of insulin results in the generation of insulin analogues that show altered binding affinities to the insulin receptor and/or IGF-I receptor. As a consequence these insulin analogues may have increased mitogenic potency. Nine benign or malignant human mammary epithelial cells, which show different insulin receptor and IGF-I receptor expression patterns, were studied regarding mitogenicity of insulin and insulin analogues. Only insulin glargine showed a significantly higher proliferative effect on MCF-7 breast cancer cells compared to regular insulin among a panel of short- or long-acting insulin analogues, that are in clinical use.
