Fucosyltransferase VII encoded by the geneFut7is essential in CD4+T cells for the generation of E- and P-selectin ligands (E- and P-lig) which facilitate recruitment of lymphocytes into inflamed tissues and into the skin.This study aimed to identify regulatory elements controlling the inducibleFut7expression in CD4+T cells that occurs upon activation and differentiation of naive T cells into effector cells.Comparative analysis of the histone modification pattern in non-hematopoetic cells and CD4+T cell subsets revealed a differential histone modification pattern within theFut7locus including a conserved non-coding sequence (CNS) identified by cross-species conservation comparison suggesting that regulatory elements are confined to this region.Cloning of the CNS located about 500 bp upstream of theFut7locus, into a luciferase reporter vector elicited reporter activity after transfection of the αβ-WT T cell line, but not after transfection of primary murine CD4+Th1 cells. As quantification of differentFut7transcripts revealed a predominance of transcripts lacking the first exons in primary Th1 cells we searched for an alternative promoter. Cloning of an intragenic region spanning a 1 kb region upstream of exon 4 into an enhancer-containing vector indeed elicited promoter activity. Interestingly, also the CNS enhanced activity of this intragenic minimal promoter in reporter assays in primary Th1 cells suggesting that both elements interact in primary CD4+T cells to induceFut7transcription.
