The upstream regulatory element could confer T-cell specificity to the GATA-3 promoter activity , and analysis of this region revealed a 707-base pair silencer that drastically inhibited GATA-3 promoter activity in non- T-cells .
 ( cell type: T-cells, None) , ( DNA: GATA-3 promoter, None) , ( DNA: upstream regulatory element, None) , ( DNA: 707-base pair silencer, None) , ( DNA: GATA-3 promoter, None) , ( cell type: non- T-cells, None)
