Anion-Channel Blockers Inhibit S-Type Anion Channels and Abscisic Acid Responses in Guard Cells.
The effects of anion-channel blockers on light-mediated stomatal opening, on the potassium dependence of stomatal opening, on stomatal responses to abscisic acid (ABA), and on current through slow anion channels in the plasma membrane of guard cells were investigated. The anion-channel blockers anthracene-9-carboxylic acid (9-AC) and niflumic acid blocked current through slow anion channels of ...
متن کاملldentification of High-Affinity Slow Anion Channel Blockers
Slow anion channels in the plasma membrane of guard cells have been suggested to constitute an important control mechanism for long-term ion efflux, which produces stomatal closing. ldentification of pharmacological blockers of these slow anion channels is instrumental for understanding plant anion channel function and structure. Patch clamp studies were performed on guard cell protoplasts to i...
متن کاملTriorganotins inhibit the mitochondrial inner membrane anion channel.
The inner membrane of liver and heart mitochondria possesses an anion uniport pathway, known as the inner membrane anion channel (IMAC). IMAC is inhibited by matrix Mg2+, matrix H+, N,N'-dicyclohexycarbodiimide, mercurials and amphiphilic amines such as propranolol. Most of these agents react with a number of different mitochondrial proteins and, therefore, more selective inhibitors have been s...
متن کاملDistinct contributions of LRRC8A and its paralogs to the VSOR anion channel from those of the ASOR anion channel
Volume- and acid-sensitive outwardly rectifying anion channels (VSOR and ASOR) activated by swelling and acidification exhibit voltage-dependent inactivation and activation time courses, respectively. Recently, LRRC8A and some paralogs were shown to be essentially involved in the activity and inactivation kinetics of VSOR currents in human colonic HCT116 cells. In human cervix HeLa cells, here,...
متن کاملCalcium Channel Blockers Nifedipine and Diltiazem Inhibit
We have undertaken a detailed study of the mechanisms of maintenance of intracellular Ca2+ homeostasis in human polymorphonuclear neutrophils (PMN) and its implications for phagocytosis and IgG Fc receptor (FcR) signaling. When PMN were incubated in Ca2+free medium, cytoplasmic calcium concentration ([Ca"+Ii) was markedly depressed and intracellular stores were depleted of calcium. [Ca2+Ii n th...
