KLF2-Regulated Gene Expression in Mouse Embryonic Yolk Sac Erythroid Cells

ABSTRACT: KLF2 is a Krüppel-like zinc-finger transcription factor required for blood vessel, lung, T-cell, and erythroid development. KLF2-/- mice die by embryonic day 14.5 (E14.5), due to hemorrhaging and heart failure. Embryonic -like globin gene expression is reduced in KLF2-/- embryos compared to wildtype (WT), and E10.5 erythroid cells exhibit abnormal morphology. Other KLF2 target genes were identified by comparing E9.5 KLF2-/- and WT yolk sac erythroid cells, using laser capture microdissection and microarray assays. One hundred and ninety-six genes exhibited significant differences in expression; eighty-nine of these are downregulated in KLF2-/- compared to WT. Genes involved in cell migration, differentiation and development are over-represented in the KLF2-regulated gene list. Previously i
