Abstract/OtherAbstract:
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 microM), the extra-cellular signal-regulated kinase inhibitor PD98059 (50 microM), and the c-Jun NH2-terminal kinase inhibitor SP 600125 (5 microM) each decreased the OTR rate by > or =50%, decreased cell proliferation, and increased G0/G1 cell cycle arrest.
