During this differentiation, the progenitor cells are exposed to changes in oxygen availability. HIF1A is the major sensor of oxygen concentration in mammalian cells. We investigated the expression of HIF1A during the in vitro differentiation of peripheral blood-derived progenitors into human mast cells. In a series of experiments, we determined the changes in CD34 expression, selected mast cell markers, and HIF1A in human mast cell cultures. While the expression of CD34 dramatically decreased, the expression of mast cell-specific genes, including FCER1A, MS4A2, TPSB2, and CMA1, steadily increased. HIF1A expression similarly increased during mast cell differentiation, reaching its maximum level at five weeks of culture. The analysis of the promoter methylation status showed decreasing levels of methylation at the HIF1A promoter, increasing levels of methylation at the CD34 promoter, and no significant changes in other genes. In silico analysis of the promoter regions of these genes revealed large CpG islands in close proximity to the HIF1A and CD34 transcription initiation sites, but not in other investigated genes. In conclusion, in vitro mast cell differentiation was associated with decreased CD34 expression and increased HIF1A expression. These changes were paralleled with changes in the methylation status of the respective promoters, suggesting that DNA methylation-dependent epigenetic regulation mediates the gene expression changes involved in maintaining the phenotype of hematopoietic stem cells and mature mast cells. Therefore, the baseline expression of HIF1A is epigenetically regulated in a cell type- and differentiation stage-specific fashion."xsd:string |
