Impaired wound healing of skin is one of the most serious complications of diabetes. However, the pathogenesis of this process is not known, and it is unclear whether impaired insulin signaling could directly affect skin physiology. To elucidate the role of insulin in skin, we studied skin insulin receptor (IR) null mice. The morphology of the skin of(More)
The insulin receptor and the insulin-like growth factor-1 receptor are widely expressed tyrosine kinases that mediate insulin and insulin-like growth factor-1 signaling. Both receptors are expressed in many cells in which insulin stimulation does not result in an increase in glucose transport, and the distinct role of the insulin receptor in these tissues,(More)
