  1. 1. Roles of voltage-gated Ca2+ channel subunits in pancreatic β cells

    Författare :Abdulla S. Kazim; Diabetes - öpatofysiologi; []
    Nyckelord :diabetes; Type 2 diabetes T2D ; Ca2 ; Ca2 channels; subunits;

    Sammanfattning : Hallmarks of type 2 diabetes (T2D) include elevated blood glucose and free fatty acids (FFAs) as a result of impaired β cell insulin secretion and decreased β cell mass. The glucose-stimulated insulin secretion (GSIS) in β cells is triggered by depolarization-evoked Ca2+ entry through voltage-gated Ca2+ (CaV) channels. LÄS MER

  3. 2. Effects of Ca2+, microRNAs, and rosuvastatin on insulin-secreting beta cell function

    Författare :Vishal Ashok Salunkhe; Diabetes - öcellsexocytos; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 diabetes; exocytosis; Ca2 ; miR-375; miR-335; rosuvastatin; voltage-gated Na channels; STXBP1; SNAP25; SYT11; glucose homeostasis; beta cell function;

    Sammanfattning : Type 2 diabetes (T2D) is a condition of high blood glucose levels due to insulin resistance and defective insulin secretion. Impaired insulin secretion plays a major role in the pathophysiology of T2D, it is mainly attributed to beta cell function i.e. failure to secrete insulin or reduced beta cell mass. LÄS MER

  4. 3. Targeting the voltage-gated calcium channels as treatment for type 2 diabetes

    Författare :Pawel Buda; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autophagy; apoptosis; calcium channels; Type 2 Diabetes;

    Sammanfattning : L-type voltage-gated Ca2+ channels are expressed in the plasma membrane of muscles, neurons and endocrine cells where they serve as conductors of signals regulating cellular responses to changes in environment. Malfunctions of channels, as well as deregulations of their activity underlie numerous disorders and diseases commonly called channelopathies. LÄS MER

  5. 4. New aspects of voltage-gated calcium channel regulation in pancreatic beta-cells - Relevance for insulin release and type 2 diabetes

    Författare :Thomas Reinbothe; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; voltage-gated calcium channels; L-type; insulin secretion; type 2 diabetes;

    Sammanfattning : Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. LÄS MER

  7. 5. Site and Mechanism of Action of Resin Acids on Voltage-Gated Ion Channels

    Författare :Malin Silverå Ejneby; Fredrik Elinder; Johan Brask; Dirk Snyders; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Voltage-gated ion channels are pore-forming membrane proteins that open or close their gates when the voltage across the membrane is changed. They underlie the electrical activity that enables the heart to pump blood and the brain to receive and send signals. LÄS MER
