[Abstract]
Collagenase-isolated islets from obese hyperglycemic mice were used to study the effects of fatty acids and ketone bodies on insulin biosynthesis. The biosynthetic rate was quantitated as the incorporation of 3H-leucine into proinsulin and insulin, which were separated from the crude islet homogenates with anti-insulin serum coupled to cyanogen bromide activated Sepharose 4B. Palmitate and oleate did not stimulate the incorporation into proinsulin and insulin while 16.7 mM glucose caused a nine-fold increase of 3H-leucine incorporation during a 3 h incubation as compared to the basal buffer alone. A weak stimulatory effect was seen with 5 mM octanoate. The ketone bodies had a weak stimulating effect on islet protein biosynthesis, but no preferential stimulus to the insulin biosynthesis was found.
