Loss of the proteasome deubiquitinase USP14 induces growth defects and a senescence phenotype in colorectal cancer cells.
Ontology highlight
ABSTRACT: The proteasome-associated deubiquitinase USP14 has attracted significant attention in recent years due to its potential as a drug target. Here, we employ an inducible USP14 knockout system to dissect early phenotypic and gene expression alterations following USP14 loss. Transcriptomic analysis revealed widespread changes in the expression of actin cytoskeleton components associated with shifts in cellular actin distribution and morphology, as well as changes in the deubiquitinase expression profile. We observed an increase in ubiquitin turnover that appeared to be offset by the upregulation of polyubiquitin genes UBB and UBC.
