We found that many of these transcription factors themselves had 5′UTRs that were enriched in binding sites for MZF-1, a transcription factor primarily known to be involved in regulating transcription in myeloid lineage precursors, and more recently in various cancers (Lenny et al., 1997; Nishiyama, 2006; Eguchi et al., 2015). Here, MZF1 is linked to cancer.
