from the results of the epo expression efficiency in transiently transfected cells , it was found that the simian virus 40 ( sv40 ) early promoter directs epo synthesis more efficiently in namalwa cells than does the long terminal repeat promoter of rous sarcoma virus and that the 3'-noncoding sequence including splice junction and polyadenylation site derived from the rabbit beta-globin gene are more effective than those of the sv40 early gene .
