| Research Abstract |
We examined(1) the assay of the activity on insulin signaling in pancreatic. cells of the mice of food restriction group(RG), and(2) the roles of insulin signaling in pancreatic. cells during catch-up growth using pancreatic. cell-specific PDK1 deficient mouse. Pancreatic. cell mass at birth was decreased in RG offspring as compared to that in control offspring(CG). A high-fat diet significantly increased the pancreatic. cell mass in RG mice as compared to that in CG mice after birth. However, RG mice fed on high-fat diets tended to exhibit a decrease in the pancreatic. cell mass at approximately 24 weeks of age. The pancreatic. cell-specific PDK1 deficient mouse showed the inhibition of increase in pancreatic. cell mass during catch-up growth.
