We performed a genome-scale shRNA screen for modulators of B-cell leukemia
progression in vivo. Results from this work revealed dramatic distinctions
between the relative effects of shRNAs on the growth of tumor cells in culture
versus in their native microenvironment. Specifically, we identified many
"context-specific" regulators of leukemia development. These included the gene
encoding the zinc finger protein Phf6. While inactivating mutations in PHF6 are
commonly observed in human myeloid and T-cell malignancies, we found that Phf6
suppression in B-cell malignancies impairs tumor progression. Thus, Phf6 is a
"lineage-specific" cancer gene that plays opposing roles in developmentally
distinct hematopoietic malignancies.
