ABSTRACT
Objective To study the relationship between cyclic adenosine monophosphate/protein kinase A (cAMP/PKA) pathway and glutamine-stimulated insulin secretion.Methods In the prerequisite of the existence of glucose(0.25 mmol/L),the insulin secretion of βHC9 cells was stimulated with different concentrations of glutamine (0.0,0.5,1.0,2.0,5.0 mmol/L),then culture liquids were extracted and centrifugalized,and the insulin levels in the cell culture liquids and the cAMP levels in βHC9 cells were determined,so as to study the effects of glutamine stimulation on the insulin level in cell culture liquids and cAMP levels in βHC9 cells were assayed.Results In the prerequisite of the glucose existence,with the increasing of the concentrations of glutamine(0.0,0.5,1.0,2.0,5.0 mmol/L),the insulin levels[0.0 ng/(mL · million),19.1 ng/(mL · million),29.1 ng/(mL · million),30.1 ng/(mL · million),33.9 ng/(mL · million)] in cell culture liquids and the cAMP levels (0.0 pmol/million,40.0 pmol/million,51.5 pmol/million,52.5 pmol/million,61.3 pmoL/million) in βHC9 cells increased accordingly.Conclusion Glutamine has amplifying effect on glucose stimulated insulin secretion,such amplifying effect needs the existence of cAMP to be prerequisite.
