Consequences of a loss of Ash2l in the bone marrow.

The Ash2l protein is a member of KMT2 enzyme complexes, which catalyse the (tri-)methylation of lysine 4 of Histone H3. H3K4me3 is considered a marker of actively transcribed genes. We determined changes in gene expression as a consequence of a conditional loss of Ash2l in the bone marrow. The expression data from the bone marrows of mice with floxed Ash2l exon 4 alleles without (control) or with an Mx1-Cre transgene (KO) and treated with synthetic dsRNA to induce recombination and the loss of Ash2l protein expression were compared. The expression data from LSK cells of the bone marrow from 3 control and 3 Ash2l KO mice were analysed and the fold changes calculated.
