Control of the HOXA9 gene expression in the hematopoietic stem/progenitor cells : role of the epigenetic factors MOZ, MLL and of the polyadenylation …

2013

My thesis project has consisted of the study of MOZ, and MLL. They are epigenetic regulators. MOZ and MLL activate transcription of HOX genes, which are transcription factors essential during haematopoiesis. MOZ and MLL have some target genes in common. In our study, we characterised a cooperation between MOZ and MLL in human haematopoietic stem/progenitor cells CD34+. They are both recruited onto HOX promoters. MOZ is essential for MLL recruitment, and this is reciprocal. In conclusion, we provided an example of a mechanism involving a direct cross-talk between two histone modifying enzymes.In order to dissect the mechanism of action of this complex, we decided to identify novel proteins i…
