Mapping of nascent RNA in MLL2 F/F and FC/FC MEF cells


ABSTRACT: Global Run-On has been performed in MLL2 F/F and FC/FC MEF cells. The aim of the experiment is to test how the lack of MLL2 affects nascent RNA transcription. Four samples were analyzed - 2 independent replicates. The experiments were performed using immortalized mouse embryonic fibroblasts (MEF) in which both MLL2 alleles were targeted by the loxp system (F/F cells). Tamoxifen treatment of the F/F cells for 24 hours results in the excision of both MLL2 alleles (FC/FC cells).

Genome instability is a recurring feature of tumorigenesis. Mutation in MLL2, encoding a histone methyltransferase, is a driver in numerous different cancer types, but the mechanism is unclear. Here, we present evidence that MLL2 mutation results in genome instability. Mouse cells in which MLL2 gene deletion can be induced display elevated levels of sister chromatid exchange, gross chromosomal aberrations, 53BP1 foci, and micronuclei. Human MLL2 knockout cells are characterized by genome instabi  ...[more]
