A novel in vivo transcription assay demonstrates the presence of globin-inducing trans-acting factors in uninduced murine erythroleukemia cells.


We report the development of a novel in vivo transcription assay for trans-acting factors regulating the human gamma- and beta-globin genes. A cDNA coding for the human tissue-type plasminogen activator (t-PA) was inserted into the globin genes. Simian virus 40 small T-antigen splice and polyadenylation signals were included to produce a mature transcript… (More)
