摘要

The intron of the corticotropin-releasing hormone (corticoliberin; CRH) gene contains a sequence of over 100 bp of alternating purine/pyrimidine residues. We have used binding of a Z-DNA-specific antibody in metabol- ically active, permeabilized nuclei to study the formation of Z-DNA in this sequence at various levels of transcription. In the NPLC human primary liver carcinoma cell line, activation of cAMP-dependent pathways increased the level of transcrip- tion, while adding glucocorticoids inhibited transcription of the CRH gene.
