Pathogenesis in Spinocerebellar Ataxia Type 3 is enhanced by the heat-shock protein family member, Hsc70-4, uncovering new mechanisms of toxicity for this disease and suggesting pleiotropic roles for chaperones.
High levels of nuclear YAP are sufficient to drive squamous cell carincoma formation and frequently also drive progression to spindle cell carcinoma by promoting epithelial-to-mesenchymal transition after tissue damage.
E3 ubiquitin ligase Bre1-induced H2B monoubiquitination is epigenetically important for recruiting replication factor Mcm10 and cohesion establishment factors Ctf4, Ctf18 and Eco1 to early replication origins to establish sister chromatid cohesion.
Hypersensitivity of cohesin-deficient cells to Wnt signaling is concomitant with beta catenin stabilization and offers promise that Wnt agonists could be therapeutically effective in cohesin mutant cancers.
Systematic analyses of DNA replication machinery components in human cells reveal a requirement of MCM-dependent de novo loading or mobilization of cohesin at replication forks in establishing sister-chromatid cohesion.
