Description
The mechanistic target of rapamycin complex 1 (mTORC1) regulates beta cell growth and mass; yet it remains unclear whether it also directs beta cell functional maturation. To understand the global molecular basis of the phenotype caused by the loss of Raptor in beta cells, we isolated pancreatic islets from 8-week-old RapKO and WT mice. We compared gene-expression profile by Affymetrix microarray of islets, which revealed that a number of mRNAs were dys-regulated in Raptor-deficient islets.
