Objective To observe the expression of calcium-dependent proline-rich tyrosine kinase-2(Pyk2) in myocardium of rheumatic heart disease,the relationship between its role and cardiac fibrosis and clinical significance.
Wortmannin, a specific inhibitor of PI3Ks, and EGFP-2xFYVE fusion protein which bind specifically with PtdIns-3-P were used to block the activity of PI3K and PtdIns-3-P separately. The results showed that the block did not change PC12 cell response to flash including its kinetics and calcium dependence.
【Objective】 To observe the activity and distribution of phosphatases and the calcium dependence of calcineurin in different tissues of rat.【Method】 The activity of calcineurin and other phosphatases in different tissues,and the activity of calcineurin in different calcium with uv-spectrophotometer.
Reviewing our results and results available in the literature it seems clear that potassium channels in ASMCs (BK_(Ca), K_(ATP) ) are activated after 2 hours of hemorrhagic shock and increase the outward potassium currents, which leads to arteriolar smooth muscle cell membrane hyperpolarization and the changes of intracellular calcium dependent characteristic.
The majority of there strains were serotype 0:10,0:6,0:9and 0:7,13.Methods Pathogenicity of 0:10,0:6,0:9and 0:7,13 were examined by the test of pyrazinamidase activity,calcium dependency,autoagglutination and plasmid detection.
Cadherins are a family of membrane receptors that mediate calcium-dependent homophilic cell-cell adhesion.
Increased concentration of Ca2+ in cytoplasm activates calcium-dependent protein kinase most likely participating in induction of transcription factors necessary for the expression of cold-regulated genes, in particular csp5.
Calcium-Dependent Nonspecific Permeability of the Inner Mitochondrial Membrane Is Not Induced in Mitochondria of the Yeast Endom
Proteolysis at this site involves the cysteine calcium-dependent neutral protease calpain.
Potential RNase targets in a tumor cell and the role of modulation of calcium-dependent potassium channels and the ras oncogene in RNase-induced cell damage are considered.
Calcium dependence of native metabotropic glutamate receptor signaling in central neurons
The curve describing the calcium dependence of nerve stimulation induced secretion of tritium labelled noradrenaline (3H-NA) from isolated guinea-pig vas deferens was sigmoid in shape.
Calcium dependence of light evoked membrane current signal and membrane voltage signal and their changes due to light adaptation
Calcium dependence of transmitter release was steep in both standard and haemolymph-like solutions, but higher external calcium concentrations were required for a given level of release in haemolymph-like solutions.
The voltage and calcium dependence suggest that the channel plays a role in adjusting K+ secretion to Na+ absorption in the fine regulation of cation excretion in renal collecting ducts.
