Abstract
The erythroleukemia cell line IW32, derived by transformation with the Friend murine leukemia virus, has been shown previously to produce erythropoietin (EPO) constitutively. Here we demonstrate that, in addition to the normal mouse EPO locus, this cell line has another EPO locus which has undergone rearrangement and amplification. Both loci were cloned, and the rearrangement breakpoint of the second EPO locus was located within a 1.1-kilobase region upstream of an otherwise apparently normal EPO gene. There are no viral sequences present in the immediate vicinity of the rearranged EPO gene. DNase I digestion studies suggest that the rearranged gene is in a region where the chromatin is more sensitive to DNase hydrolysis than is the site of the normal gene. We conclude, tentatively, that the rearranged EPO locus is probably the transcriptionally active one and that either proviral sequences are acting at a distance to activate the EPO gene or the rearrangement itself has served to activate the gene.
