Abstract
Cell swelling is associated with the activation of an increase in the osmosensitive taurine release (OTR) rate, which serves to decrease cell volume as part of a process known as regulatory volume decrease. OTR, which is sensitive to many pharmacological agents including anion channel blockers and signalling pathway modulators, has also been suggested to play a role in cell cycle progression. At non-cytotoxic concentrations, the anion channel blocker NPPB (25 uM), the extra-cellular signal-regulated kinase inhibitor PD98059 (50 uM), and the c-Jun NH2-terminal kinase inhibitor SP 600125 (5 uM) each decreased the OTR rate by aY=50%, decreased cell proliferation, and increased G0/G1 cell cycle arrest.
