Identification of hypoxia target genes in human CB CD34+ cells


ABSTRACT: Although it has been shown that HIF1 and 2 fulfill essential roles within the hematopoietic system and in the regulation of HSC fate, little is currently known about the specific mechanisms that are involved. We identified transcriptome changes induced by hypoxia, constitutively active HIF1(P402/564) and HIF2(P405/531) in human cord blood CD34+ cells. Thus, we were able to identify common hypoxia-HIF1-HIF2 gene signatures, but we also identified specific target genes that were exclusively regulated by HIF1, HIF2 or hypoxia. CB CD34+ cells were isolated by Miltenyi miniMACS column. Cells were prestimulated in HPGM with 100 ng/ml KITL, FLT3L and TPO for 3 days after which cells were placed either at normoxia or hypoxia (1% O2 for an additional 24 hrs). 5 independent CB CD34+ batches were used and isolated RNA was combined and used for Illumina beadhchip arrays HT12 v4
