Mitochondrial damages and the regulation of insulin secretion.
Pancreatic beta-cells are able to respond to nutrients, principally glucose, as the primary stimulus for insulin exocytosis. This unique feature requires translation of metabolic substrates into intracellular messengers recognized by the exocytotic machinery. Central to this signal transduction mechanism, mitochondria integrate and generate metabolic signals, thereby coupling glucose recognitio...
متن کاملLack of Association of Mitochondrial A3243G tRNALeu Mutation in Iranian Patients with Type 2 Diabetes
Many kinds of mutations in mitochondrial (mt) DNA have been reported to be related to the development of Diabetes Mellitus (DM), this type of diabetes has also been shown to be influenced by other genetic factors and/or environmental factors. Among them, tRNALeu(UUR) and its adjacent mtDNA NADH dehydrogenase subunit 1(ND1) region within the mt genome are linked to high susceptibility to DM. A p...
متن کاملSingle-cell A3243G mitochondrial DNA mutation load assays for segregation analysis.
Segregation of mitochondrial DNA (mtDNA) is an important underlying pathogenic factor in mtDNA mutation accumulation in mitochondrial diseases and aging, but the molecular mechanisms of mtDNA segregation are elusive. Lack of high-throughput single-cell mutation load assays lies at the root of the paucity of studies in which, at the single-cell level, mitotic mtDNA segregation patterns have been...
متن کاملMitochondrial DNA A3243G mutation involved in familial diabetes, chronic intestinal pseudo-obstruction and recurrent pancreatitis.
AIMS To report on a family with five members who carry the A3243G mutation in mitochondrial tRNA for leucine 1 (MTTL1) and present with diabetes, chronic intestinal pseudo-obstruction (CIPO) and recurrent pancreatitis, and to screen for this mutation in a cohort of 36 unrelated patients with recurrent pancreatitis. METHODS The mutation was quantified in several tissue samples from patients. R...
