Insulin exocytosis
NettetMiR-9 is produced by mapping three genes of miR-9-1, miR-9-2, and miR-9-3 in the human genome to chromosomes 1, 5, and 15, respectively. 30 MiR-9 mediate insulin exocytosis in insulin-producing cells through direct targeting Onecut-2 (OC-2) mRNA. As a result, decreased expression of the OC-2 can increase the Granuphilin levels, as its target gene. Nettet15. mar. 2024 · The rhythmic nature of insulin secretion over the 24h cycle in pancreatic islets has been mostly investigated using transcriptomics studies showing that modulation of insulin secretion over this cycle is achieved via distal stages of insulin secretion. We set out to measure β-cell exocytosis using in depth cell physiology techniques at …
