Proinsulin-like component of circulating insulin in the basal state and in patients and hamsters with islet cell tumors

RESUMO

The proinsulin-like component comprised approximately 20% of total circulating basal immunoreactive insulin in 15 patients without islet cell tumors. 15 min after oral glucose, the concentration of the proinsulin-like component was unchanged and its percentage of the total immunoreactive insulin decreased with the acute release of the insulin component. By 2 hr after oral glucose, the concentration of the proinsulin-like component increased and the insulin component concentration decreased so that the percentage of the proinsulin-like component was essentially the same as in the basal state.
