-globin gene, we investigated -gene expression during the
development of transgenic mice carrying constructs with -promoter
truncations linked to a micro-locus control region (µLCR). Expression
levels were compared with those of µLCR mice carrying a 2 kilobase
-promoter and 
YAC controls. mRNA in the embryonic cells
of µLCR (
179) mice were as high as in µLCR mice suggesting
that the proximal -promoter contains most elements required for
-gene activation. mRNA in adult µLCR (179) mice was
significantly lower than in the embryonic cells indicating that
elements involved in -gene silencing are contained in the proximal
-promoter. Extension of the promoter sequence to 463 decreased
-gene expression in the definitive erythroid cells, supporting
previous evidence that the 179 to 463 region contains an
-gene silencer. However, the -gene of the µLCR(463) mice
was not silenced in the definitive cells of fetal and adult
erythropoiesis indicating that additional silencing elements are
located upstream of position 463. These results provide in
vivo evidence that multiple elements of the distal as well as the
proximal promoter contribute to -gene silencing.
