Groudine, M and Eisenman, R and Weintraub, H (1981) Chromatin structure of endogenous retroviral genes and activation by an inhibitor of DNA methylation. Nature, 292 (5821). pp. 311-317. ISSN 0028-0836
Abstract
The transcriptionally active ev-3 and inactive ev-1 endogenous retrovirus loci in chick cells differ in that ev-3 is undermethylated, preferentially sensitive to DNase I digestion, and contains nuclease hypersensitive sites in each of its two long terminal repeats. Transient exposure of cells to 5-azacytidine, a cytosine analogue which cannot be methylated at the 5 position, results in the hypomethylation and transcriptional activation of ev-1, as well as the acquisition of at least one nuclease-hypersensitive site within the chromosomal domain of ev-1.
