Gene Deregulation in MLL-Fusion Gene Leukemia

Infant leukemia and secondary leukemias are associated with translocations involving the MLL gene. The researchers are investigating the molecular pathogenesis of leukemia caused by these MLL-fusion genes. They have identified changes in gene expression caused by the fusion gene in a mouse model of MLL-AF9 fusion gene leukemia.

Ongoing and future experiments will identify the genes regulated by a different MLL-fusion protein, MLL-AF4, and those regulated by MEIS1, an important downstream target of MLL-fusion proteins. This information will significantly add to our understanding of the molecular pathogenesis of these disorders, which will then help in the development of newer therapeutic strategies.

This project uses resources available at the CGL.
