Isoflurane modulates key components of the RhoA signaling cascade. Isoflurane-induced actin cytoskeleton-mediated disturbances of glial morphological transformation and growth are associated with modulation of the RhoA/MLC-mediated cascade. Substantial downregulation of endogenous RhoA and myosin light chain/phosphorylated myosin light chain (MLC/MLC-P) coincides with significant downregulation of endogenous paxillin and disturbances in glial growth, morphological transformation, and the formation of actin stress fibers (ASF).
