Quantitative analysis of Id1 Wild Type and Id1 knockout  hematopoietic stem cells transcriptome
To explore the molecular basis by which Id1 loss promotes HSC quiescence under stress we compared the transcriptome of Id1-/- and Id1+/+ HSCs isolated from primary BMT recipient mice by RNA-seq. We found 179 upregulated and 1476 downregulated genes in Id1-/- HSCs compared to Id1+/+ HSCs using a fold-change cut-off of 2 . Collectively, the IPA analysis shows that Id1-/- HSCs have gene expression profiles consistent with reduced response to stress, reduced cycling and proliferation, and reduced ribosomal biogenesis and protein synthesis, which is consistent with our hypothesis that Id1-/- HSCs have molecular signature of quiescent HSCs compared to Id1+/+ HSCs. Overall design: RNA was isolated from HSCs FACS purified from mice transplanted with Lin- Id1-/- and Id1+/+ BMCs after 6 weeks for RNA-seq  analysis.
