| Research Abstract |
During pregnancy, the increase of pancreatic beta cell mass is observed to compensate for insulin resistance. In this regard, we reported that increased production of serotonin in pancreatic beta cells elicits the proliferation of pancreatic beta cells (Kim H. et al Nat Med 16:804-808, 2010), however there have been no reports showing the expression of serotonin in pancreatic beta cells in non-pregnant period. Recently, we found the expression of serotonin in pancreatic beta cells in RIP (rat insulin promoter)- Cre mouse generated by Dr. Magnuson’ s group in non-pregnant period. However, we found no serotonin expression in beta cells in another line of RIP-Cre mice generated by Dr. Herrera’ s mice and PDX-1 Cre mice. These results suggest that the change of the expression of the gene located near the integration site of Cre in RIP - Cre mouse generated by Dr. Magnuson’ s group may cause the change of the expression of serotonin.
