Abstract

This paper reports on the involvement of c-MYB in the regulation of 5-lipoxygenase gene expression during differentiation of human HL-60 cells. We demonstrate that c-MYB binds, the 5-lipoxygenase promoter in undifferentiated cells but not in DMSQ-diif ferentiated cells. Also, we show that overexpression of c-myb cDNA in differentiated HL-60 cells represses the 5-lipoxygenase gene expression.

分化HL-60细胞中c-myb过表达对5-脂氧合酶基因的抑制作用
本文报道了c-MYB参与人HL-60细胞分化过程中5-脂氧合酶基因表达的调控。我们证明c-MYB在未分化的细胞中与5-脂氧合酶启动子结合,但在dmsq分化的细胞中不结合。此外,我们发现c-myb cDNA在分化的HL-60细胞中过表达会抑制5-脂氧合酶基因的表达。
