WebThe TGF-β signaling pathway controls cellular proliferation, growth and differentiation and regulates several functions of the connective tissue.Disruption of genes coding for components of the TGF-β signaling pathway or its interactors, such as fibrillin-1, has been shown to cause several human pathologies. WebApr 1, 2024 · Chromothripsis is defined as the mechanism by which tens to hundreds of locally clustered DNA rearrangements are formed, typically in one or a few chromosomes, caused by a single event sometimes accompanied by double-minute chromosomes [ 1 ].
WebMay 14, 2024 · This chromothriptic event was linked to concordant upregulation of 96 loci that predominantly regulate cell-cycle machineries in advanced luminal tumors. Genome-editing analysis confirmed that an ERα hub localized on 20q13 coordinately regulates a subset of these loci localized on 17q23 through long-range chromosome interactions. WebIn chromothriptic medulloblastoma, an ecosystem of cells from multiple genetic clones resisting treatment and leading to relapse highlighted the importance of multi-clone interplay. Finally, we identified a potential role for tumour microtubes in treatment resistance in chromothriptic medulloblastoma, suggesting cell network communication as a ...
