WebTo examine the effects of houttuynin on ventricular remodeling induced by coronary artery ligation in rats and the underlying mechanisms. A rat model of ventricular remodeling was established by left coronary artery ligation (CAL). Rats were randomly divided into four groups: CAL control, CAL plus 40 mg/kg captopril, CAL plus 100 mg/kg houttuynin and … WebTwo highly specialized cells, this guard cells so surround the stomatal pore, are able to integrate environmental and endogenous signals in order to control the stomatal aperture furthermore with the gas exchange.

Those more "typical" potassium channels preferentially carry outward (rather than inward) potassium currents at depolarized membrane potentials, and may be thought of as "outwardly rectifying." When first discovered, inward rectification was named "anomalous rectification" to distinguish it from outward … See more Inward-rectifier potassium channels (Kir, IRK) are a specific lipid-gated subset of potassium channels. To date, seven subfamilies have been identified in various mammalian cell types, plants, and bacteria. They are … See more The phenomenon of inward rectification of Kir channels is the result of high-affinity block by endogenous polyamines, namely spermine, … See more Kir channels are found in multiple cell types, including macrophages, cardiac and kidney cells, leukocytes, neurons, and endothelial cells. By … See more The crystal structure and function of bacterial members of the IRK-C family have been determined. KirBac1.1, from Burkholderia pseudomallei, is 333 amino acyl residues (aas) long with two N-terminal TMSs flanking a P-loop (residues 1-150), and the C … See more A channel that is "inwardly-rectifying" is one that passes current (positive charge) more easily in the inward direction (into the cell) than in the outward direction (out of the cell). It is thought that this current may play an important role in regulating neuronal activity, by … See more All Kir channels require phosphatidylinositol 4,5-bisphosphate (PIP2) for activation. PIP2 binds to and directly activates Kir … See more Voltage-dependence may be regulated by external K , by internal Mg , by internal ATP and/or by G-proteins. The P domains of IRK channels exhibit … See more WebA plant Shaker-like K+ channel switches between two distinct gating modes resulting in either inward-rectifying or ‘leak’ current . × Close Log In.
