WS Zawalich, KC Zawalich - Journal of Biological Chemistry, 2002 - ASBMB Isolated perifused rat islets were stimulated with glucose, exogenous insulin,
or carbachol. C-peptide and, where possible, insulin secretory rates were
measured. Glucose (8-10 mM) induced dose-dependent and kinetically similar ... Cited by 21 - Related articles - BL Direct - All 6 versions
J Westerlund, BA Wolf, P Bergsten - Diabetes, 2002 - Am Diabetes Assoc An insulin-mimetic compound (L-783,281) was used in an attempt to determine the
role of the β-cell insulin receptor (IR) on insulin release. Islets were
isolated from C57Bl/6j mice and cultured for 1 to 4 days. Insulin release ... Cited by 8 - Related articles - BL Direct - All 5 versions

in regulating its own secretion, either in rodent islets or in human islets. We
have now investigated whether there is an autocrine signalling role for ... Cited by 46 - Related articles - All 7 versions

to be important in beta-cell function. We show here that insulin directly
regulates beta-cell function in isolated rodent islets. Long-term insulin ... Cited by 41 - Related articles - BL Direct - All 3 versions
