The oncogene EVI1 causes an aggressive leukemia, but its exact function has been a mystery
In cancer cells, chromosomes are often destroyed and recombined, which leads to changes
Johannes Zuber of the Institute of Molecular Pathology (IMP) said: "We have many experimental tools to study gene function in cancer, but in EVI1-driven cases of AML, we lack the relevant disease models
Eventually, overcoming many difficulties, Inês Barbosa, then a doctoral student in Zuber's lab, succeeded in creating a new model of EVI1-driven AML that made genetic experimentation possible
Johannes Schmoellerl, who was a doctoral student in Grebien's lab before joining Zuber lab as a postdoc, uses "gene scissors" CRISPR-Cas9 to eliminate genes
The scientists then tried to find out exactly how important
Johannes Schmoellerl said: "While there are different mechanisms that can lead to the expression of EVI1, their main function is focused on
EVI1 drives leukemogenesis through aberrant ERG activation
