Project description:comparison of mRNA expression in the islets of 3- and 12-month old male Wistar rats Aging is a risk factor for a majority of metabolic diseases including type 2 diabetes. During aging pancreatic beta-cell function decreases leading to impaired insulin secretion and proliferation and to an increase in apoptosis. Impairment of pancreatic beta cell functions and survival has been linked to gene expression changes. The aim of our study was to obtain a global expression profile of microRNAs and mRNAs of pancreatic islets of 3 and 12 month old male Wistar rats in order to identify the changes occurring during aging.

Proteomic profiles of Rat Pancreatic Islets

Project description:In this study, we achieved integrated transcriptomic and proteomic profiles of GK islets in a time-course fashion at different stages of T2D. Subsequent bioinformatics analysis revealed the chronological order of T2D-related molecular events during the deterioration of pancreatic islets. Our large quantitative dataset provide a valuable resource to obtain a comprehensive picture of the mechanisms responsible for islet dysfunction and to identify potential interventions to prevent beta-cell failure in human T2D.
