Abstract:Extracellular stimuli in the injured CNS, such as chondroitin sulfate proteoglycans, inhibit axon growth through activation of the small GTPase RhoA. This RhoA activation increases intracellular Ca2+ that converges on an HDAC6-dependent pathway to deacetylate Miro1. Deacetylation of Miro1 decreases mitochondrial transport and attenuates axon growth.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
