The relationship between phosphorylation of myosin light chain (MLC) and neurite outgrowth induced by nerve growth factor (NGF) was studied in PC12 cells. Inhibitors of Rho kinase, HA-1077 or Y-27632 also induced neurite outgrowth. As already reported botulinum exoenzyme C3 which inactivates Rho protein also induced neurite outgrowth. Calyeulin A, an inhibitor of phosphatase counteracted both NGF- and C3- induced neurite outgrowth. Treatments of both NGF and C3 resulted in significant and transient decrease in phosphorylated MLC. These results suggest that NGF induces neurite outgrowth of PC12 by a transient decrease in phosphorylated MLC which is brought about by activation of MLC phosphatase via inhibition of Rho-Rho kinase pathway.

D016501 Neurites In tissue culture, hairlike projections of neurons stimulated by growth factors and other molecules. These projections may go on to form a branched tree of dendrites or a single axon or they may be reabsorbed at a later stage of development. "Neurite" may refer to any filamentous or pointed outgrowth of an embryonal or tissue-culture neural cell. Neurite
D016716 PC12 Cells A CELL LINE derived from a PHEOCHROMOCYTOMA of the rat ADRENAL MEDULLA. PC12 cells stop dividing and undergo terminal differentiation when treated with NERVE GROWTH FACTOR, making the line a useful model system for NERVE CELL differentiation.

D054460 rho-Associated Kinases A group of intracellular-signaling serine threonine kinases that bind to RHO GTP-BINDING PROTEINS. They were originally found to mediate the effects of rhoA GTP-BINDING PROTEIN on the formation of STRESS FIBERS and FOCAL ADHESIONS. Rho-associated kinases have specificity for a variety of substrates including MYOSIN-LIGHT-CHAIN PHOSPHATASE and LIM KINASES. rho-Associated Kinase,ROCK Protein Kinases,ROCK-I Protein Kinase,ROCK-II Protein Kinase,ROK Kinase,p160 rhoA-Binding Kinase ROKalpha,p160ROCK,rho-Associated Coiled-Coil Containing Protein Kinase 1,rho-Associated Coiled-Coil Containing Protein Kinase 2,rho-Associated Coiled-Coil Kinase,rho-Associated Kinase 1,rho-Associated Kinase 2,rho-Associated Kinase alpha,rho-Associated Kinase beta,rho-Associated Protein Kinase alpha,rho-Associated Protein Kinase beta,rho-Kinase,Coiled-Coil Kinase, rho-Associated,Protein Kinases, ROCK,ROCK I Protein Kinase,ROCK II Protein Kinase,p160 rhoA Binding Kinase ROKalpha,rho Associated Coiled Coil Containing Protein Kinase 1,rho Associated Coiled Coil Containing Protein Kinase 2,rho Associated Coiled Coil Kinase,rho Associated Kinase,rho Associated Kinase 1,rho Associated Kinase 2,rho Associated Kinase alpha,rho Associated Kinase beta,rho Associated Kinases,rho Associated Protein Kinase alpha,rho Associated Protein Kinase beta,rho Kinase
D018994 Myosin Light Chains The smaller subunits of MYOSINS that bind near the head groups of MYOSIN HEAVY CHAINS. The myosin light chains have a molecular weight of about 20 KDa and there are usually one essential and one regulatory pair of light chains associated with each heavy chain. Many myosin light chains that bind calcium are considered "calmodulin-like" proteins.
