The effects of IGF-2 on glucose homeostasis have been more understood from individuals with fasting hypoglycaemia associated with non-islet cell tumours. Endogenous IGFs which circulate in adults fail to exert their immense potential hypoglycaemic activity because they are largely trapped within the vascular space due to their sequestration in a high molecular weight protein complex. The tumours produce excessive amounts of ‘big IGF-2’ which is less readily bound by ...
