Genes required for the normal progression of mitosis represent potential CIN genes and, as such, are important tumour suppressors. The Chk2 kinase and its downstream targets p53 and Brca1 are tumour suppressors that have been functionally linked to the DNA damage response pathway2. Here, we report a function of Chk2, independent of p53 and DNA damage, that is required for proper progression of mitosis, and for the maintenance of chromosomal stability in human somatic cells. Depletion of Chk2 or abrogation of its kinase activity causes abnormal mitotic spindle assembly associated with a delay in mitosis, which promotes the generation of lagging chromosomes, chromosome missegregation and CIN, while still allowing survival and growth. Furthermore, we have identified Brca1 as a mitotic target of the Chk2 kinase in the absence of DNA damage. Accordingly, loss of BRCA1 or its Chk2-mediated phosphorylation leads to spindle formation defects and CIN. Thus, the CHK2–BRCA1 tumour suppressor pathway is required for chromosomal stability, which might contribute to their tumour suppressor function."],["dc.identifier.doi","10.1038/ncb2051"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6282"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60314"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","610"],["dc.title","The CHK2–BRCA1 tumour suppressor pathway ensures chromosomal stability in human somatic cells"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

We identified a specific cluster of genes that was coherently expressed in primary lymphoma samples and suppressed by activation of the B cell receptor (BCR) through aIgM treatment of lymphoma cells in vitro. This gene cluster, which we called BCR. 1, includes numerous cell cycle regulators. A reduced expression of BCR. 1 genes after BCR activation was observed in different cell lines and also in CD10(+) germinal center B cells. We found that BCR activation led to a delayed entry to and progression of mitosis and defects in metaphase. Cytogenetic changes were detected upon long-term aIgM treatment. Furthermore, an inverse correlation of BCR. 1 genes with c-Myc co-regulated genes in distinct groups of lymphoma patients was observed. Finally, we showed that the BCR. 1 index discriminates activated B cell-like and germinal centre B cell-like diffuse large B cell lymphoma supporting the functional relevance of this new regulatory circuit and the power of guided clustering for biomarker discovery."],["dc.identifier.doi","10.18632/oncotarget.9219"],["dc.identifier.isi","000385413000020"],["dc.identifier.pmid","27166259"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14137"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/40052"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Impact Journals Llc"],["dc.relation.issn","1949-2553"],["dc.rights","CC BY 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/3.0"],["dc.title","Identification of a new gene regulatory circuit involving B cell receptor activated signaling using a combined analysis of experimental, clinical and global gene expression data"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
