Localization and phenotype-specific expression of ryanodine calcium release channels in C57BL6 and DBA/2J mouse strains.
The DBA/2J (D2) and C57BL6 (B6) mouse strains are widely used in research as models for anxiety, addiction and chronic glaucoma. D2, but not B6, animals develop elevated intraocular pressure (IOP) that leads to progressive degeneration of retinal ganglion cell (RGC) axons and perikarya. Here we compare the expression and localization of intracellular ryanodine receptor (RyR) Ca(2+) store mechan...
متن کاملRyanodine receptor calcium release channels.
The ryanodine receptors (RyRs) are a family of Ca2+ release channels found on intracellular Ca2+ storage/release organelles. The RyR channels are ubiquitously expressed in many types of cells and participate in a variety of important Ca2+ signaling phenomena (neurotransmission, secretion, etc.). In striated muscle, the RyR channels represent the primary pathway for Ca2+ release during the excit...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Coupled gating between cardiac calcium release channels (ryanodine receptors).
Excitation-contraction coupling in heart muscle requires the activation of Ca(2+)-release channels/type 2 ryanodine receptors (RyR2s) by Ca(2+) influx. RyR2s are arranged on the sarcoplasmic reticular membrane in closely packed arrays such that their large cytoplasmic domains contact one another. We now show that multiple RyR2s can be isolated under conditions such that they remain physically c...
متن کاملCoupled gating between individual cardiac ryanodine calcium release channels.
In order to study interactions between ryanodine receptor calcium release (RyR2) channels during excitation-contraction coupling in cardiac muscle, we used bilayer lipid membrane (BLM) and improved the method of cardiac sarcoplasmic vesicle fusion into BLM. We increased fusion gradient for the vesicles, used chloride ions for fusion up to concentration of 1.2 mol/l and fused the vesicles by add...
