H3K27me3 is deposited at promoters by the preferential association of Polycomb repressive complex 2 (PRC2) with CpG-rich DNA elements regulating development by repressing gene transcription. H3K27 is also present in mono- and dimethylated states; however, the functional roles of H3K27me1 and H3K27me2 deposition remain poorly characterized. Here, we show(More)
The Ndc80 complex is a constituent of the outer plate of the kinetochore and plays a critical role in establishing the stable kinetochore-microtubule interactions required for chromosome segregation in mitosis. The Ndc80 complex is evolutionarily conserved and contains the four subunits Spc24, Spc25, Nuf2, and Ndc80 (whose human homologue is called Hec1).(More)
BACKGROUND Mad1 and Mad2 are constituents of the spindle-assembly checkpoint, a device coupling the loss of sister-chromatid cohesion at anaphase to the completion of microtubule attachment of the sister chromatids at metaphase. Fluorescence recovery after photobleaching (FRAP) revealed that the interaction of cytosolic Mad2 with kinetochores is highly(More)
Cell type specification, transcription factor binding site selection and transcriptional regulation are specific processes that require a fine regulation that cannot be simply explained by the mere DNA sequence. Similarly, genome stability, damage response as well as genomic imprints and X-chromosome inactivation are all processes that involve an epigenetic(More)
Leukemia is a complex heterogeneous disease often driven by the expression of oncogenic fusion proteins with different molecular and biochemical properties. Whereas several fusion proteins induce leukemogenesis by activating Hox gene expression (Hox-activating fusions), others impinge on different pathways that do not involve the activation of Hox genes(More)
Hepatocellular carcinoma (HCC) is the most common type of liver cancer in humans. The focal adhesion tyrosine kinase (FAK) is often over-expressed in human HCC and FAK inhibition may reduce HCC cell invasiveness. However, the anti-oncogenic effect of FAK knockdown in HCC cells remains to be clarified. We found that FAK depletion in HCC cells reduced in(More)
