Plasma membrane large-conductance Ca(2+)-activated K(+) (BK(Ca)) channels and sarcoplasmic reticulum inositol 1,4,5-trisphosphate (IP(3)) receptors (IP(3)Rs) are expressed in a wide variety of cell types, including arterial smooth muscle cells. Here, we studied BK(Ca) channel regulation by IP(3) and IP(3)Rs in rat and mouse cerebral artery smooth muscle(More)
Transmembrane protein (TMEM)16A channels are recently discovered membrane proteins that display electrophysiological properties similar to classic Ca(2+)-activated Cl(-) (Cl(Ca)) channels in native cells. The molecular identity of proteins that generate Cl(Ca) currents in smooth muscle cells (SMCs) of resistance-size arteries is unclear. Similarly, whether(More)
Cisplatin is important in the treatment of various types of cancer. Although it is highly effective, it also has severe side effects, with neurotoxicity in dorsal root ganglion (DRG) neurons being one of the most common. The key mechanisms of neurotoxicity are still controversially discussed; however, disturbances of the calcium homeostasis in DRG neurons(More)
Brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family and a ligand for the tropomyosin-receptor kinase B (TrkB), mediates neuronal survival, differentiation, and synaptic plasticity. However, BDNF is not used to treat neurodegenerative diseases because of its poor pharmacokinetic profile, side effects, and absence of survival(More)
Previous studies report functional differences in large conductance Ca2+ activated-K+ channels (BKCa) of smooth muscle cells (VSMC) from rat cerebral and cremaster muscle resistance arteries. The present studies aimed to determine if this complexity in BKCa activity may, in part, be due to splice variants in the pore-forming α-subunit. BKCa variants in the(More)
2+-activated K + (BK Ca) channels are expressed in a wide variety of cell types and consist of pore-forming  subunits and auxiliary 1–4 subunits that modify channel function (Lu et al., 2006). In arterial smooth muscle cells, 1 subunits are the principal molecular and functional BK Ca channel auxiliary subunit isoform (Brenner et al., 2000; Plüger et(More)
