Variants in the Cav2.3 ( 1E) Subunit of Voltage-Activated Ca Channels Are Associated With Insulin Resistance and Type 2 Diabetes in Pima Indians
OBJECTIVE—Linkage to type 2 diabetes has been reported on chromosome 1q21-25 in Pima Indians. Fine mapping identified single nucleotide polymorphisms (SNPs) near the CACNA1E gene associated with this disease. CACNA1E encodes the voltage-dependent calcium channel Cav2.3 Ca 2 , and mice lacking this channel exhibit impaired glucose tolerance and insulin secretion. Therefore, CACNA1E was investiga...
متن کاملDisruption of Growth Hormone Secretion Alters Calcium Current Density and the Expression of Calcium Channel and Insulin-Like Growth Factor Genes in Rat Atria
The influence of the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis on the expression of low voltage-activated (LVA) calcium current in atrial tissue was investigated using spontaneous dwarf (SpDwf) rats, a mutant strain that lacks GH. Atrial myocytes from SpDwf rats express LVA and HVA calcium currents and the calcium channel alpha-1 subunit genes, CaV1.2, CaV2.3, CaV3.1, and CaV3...
متن کاملCaV2.3 calcium channels control second-phase insulin release.
Concerted activation of different voltage-gated Ca( (2+) ) channel isoforms may determine the kinetics of insulin release from pancreatic islets. Here we have elucidated the role of R-type Ca(V)2.3 channels in that process. A 20% reduction in glucose-evoked insulin secretion was observed in Ca(V)2.3-knockout (Ca(V)2.3(-/-)) islets, close to the 17% inhibition by the R-type blocker SNX482 but mu...
متن کاملGender specific hippocampal whole genome transcriptome data from mice lacking the Cav2.3 R-type or Cav3.2 T-type voltage-gated calcium channel
Voltage-gated Ca2+ channels are of central relevance in mediating numerous intracellular and transcellular processes including excitation-contraction coupling, excitation secretion-coupling, hormone and neurotransmitter release and gene expression. The Cav2.3 R-type Ca2+ channel is a high-voltage activated channel which plays a crucial role in neurotransmitter release, long-term potentiation an...
متن کاملApamin Boosting of Synaptic Potentials in CaV2.3 R-Type Ca2+ Channel Null Mice
SK2- and KV4.2-containing K+ channels modulate evoked synaptic potentials in CA1 pyramidal neurons. Each is coupled to a distinct Ca2+ source that provides Ca2+-dependent feedback regulation to limit AMPA receptor (AMPAR)- and NMDA receptor (NMDAR)-mediated postsynaptic depolarization. SK2-containing channels are activated by Ca2+ entry through NMDARs, whereas KV4.2-containing channel availabil...
