Abstract:Introduction: Gain-of-function mutations in the gene that encodes the ErbB4 receptor tyrosine kinase have been found in a significant fraction of melanoma samples. Melanoma cell lines that harbor some of these mutations are dependent on ErbB4 for proliferation. However, there is a scarcity of therapeutics for treating these ErbB4-dependent melanomas. Our drug discovery approach is based on the observation that the Q43L mutant of the ErbB4 agonist Neuregulin 2beta (NRG2b) functions as a partial agonist/antagoni… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
