Abstract:We have previously characterized a mechanism of 5HT-stimulated extracellular signal-regulated kinases 1 and 2 (ERK1/2) activation via the non-RNA-edited isoform of the serotonin 5HT(2C) receptor (5HT(2C)R-INI) in a CHO cell line. We have now used CV1 cells, which endogenously express epidermal growth factor receptors (EGFRs), to investigate whether the mechanisms underlying ERK1/2 activation by the 5HT(2C)R change in a time-, agonist-, and cell background-dependent manner. Interrogation of the CV1 5HT(2C)R-INI…
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.
