Abstract:The avian sarcoma virus genome (Schmidt-Ruppin strain) in transformed hamster cells resistant to 8-azaquanine [Ha(SR)AG-50] was strongly suppressed. The suppression was genetically stable and could not be overcome by attempts at induction with 5-iodo-2'-deoxyuridine. Fusion of hamster cells, which had suppressed virus genome, with chicken Rous-associated virus (RAV-1)-preinfected cells easily rescued the sarcoma virus. The rescued virus had envelope properties of RAV-1, as determined by viral interference, vir… 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.
