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 EMT-associated stem cell properties through transcriptional(More)
Extracellular interaction between programmed death ligand-1 (PD-L1) and programmed cell death protein-1 (PD-1) leads to tumour-associated immune escape. Here we show that the immunosuppression activity of PD-L1 is stringently modulated by ubiquitination and N-glycosylation. We show that glycogen synthase kinase 3β (GSK3β) interacts with PD-L1 and induces(More)
During the process of tumorigenesis, inactivation of tumor suppressors is a critical step. EZH2, a histone methyltransferase, promotes cell growth and migration through catalyzing trimethylation of histone H3 at Lys 27 (H3K27me3) and plays an important role in tumorigenesis. Its expression can be controlled by phosphorylation. However, the regulation of(More)
