We performed a search in ChIPbase (http://deepbase.sysu.edu.cn/chipbase) and found that several important T-ALL transcriptional factors such as c-myc and CDX2 bind to the promoter of HMGA2, suggesting that they could upregulate HMGA2 expression in some human T-ALL cases.20, 21. This evidence concerns the gene CDX2 and acute lymphoblastic leukemia.
