The epithelial–mesenchymal transition (EMT) has recently been linked to stem cell phenotype . However, the molecular mechanism underlying EMT and regulation of stemness remains elusive. Here, using genomic approaches, we show that tumour suppressor p53 has a role in regulating both EMT and...
The ability to respond to perturbations in endoplasmic reticulum (ER) function is a fundamentally important property of all cells, but ER stress can also lead to apoptosis. In settings of chronic ER stress, the associated apoptosis may contribute to pathophysiological processes involved in a...
Protein ubiquitylation is a key post-translational control mechanism contributing to different physiological processes, such as signal transduction and ageing. The size and linkage of a ubiquitin chain, which determines whether a substrate is efficiently targeted for proteasomal degradation, is...
Clathrin-mediated endocytosis (CME) is the best-studied pathway by which cells selectively internalize molecules from the plasma membrane and surrounding environment. Previous live-cell imaging studies using ectopically overexpressed fluorescent fusions of endocytic proteins indicated that...
