p38β-mediated BiP phosphorylation drives stemness and chemoresistance by suppressing UPR activation in hepatocellular carcinoma

Abstract Tumor-initiating cells (TICs) promote tumor initiation and therapy resistance, yet the kinase regulators that sustain TICs remain incompletely defined. Here, we identify the stress kinase p38β (MAPK11) supports TIC maintenance and drug resistance in hepatocellular carcin...
