pubmed:abstractText |
Recently, DNA sequences containing four erythroid-specific DNase I hypersensitive sites within 20 kilobases 5' of the human epsilon-globin gene have been identified as an important cis-acting regulatory element, the locus activation region (LAR). Subfragments of the LAR, containing either all or only the two 5' or two 3' hypersensitive sites were linked to the human beta-globin gene and analyzed for their effect on globin gene expression in stably transformed mouse erythroleukemia (MEL) cells. Constructs containing all four of the hypersensitive sites increase beta-globin mRNA levels 8- to 13-fold, while constructs with only the 5' or 3' sites increase globin expression to a lesser extent. No effect was seen when the constructs were assayed in 3T3 fibroblasts. All of the LAR derivatives form hypersensitive sites at the corresponding sequence position in MEL cells prior to and after induction of MEL cell differentiation. However, in 3T3 fibroblasts only the hypersensitive site corresponding to the previously described erythroid-specific -10.9 site was formed.
