NettetInsulin synthesis in pancreatic β-cells is initiated as preproinsulin. Prevailing glucose concentrations, which oscillate pre- and postprandially, exert major dynamic variation in preproinsulin biosynthesis. Accompanying upregulated translation of the insulin precursor includes elements of the endop … NettetFurther evidence that glucose stimulates insulin synthesis at the transcriptional level was obtained by previously incubating islets in 2.8 or 15.3 m m glucose for 45 min in the presence of cycloheximide sufficient to inhibit islet protein synthesis by 90%. Cycloheximide was then washed out and and the islets incubated in high (15.3 m m) …
