Background and Aims
Activated hepatocytes are hypothesized to be a major source of signals that drive cirrhosis, but the biochemical pathways that convert hepatocytes into such a state are unclear. We examined the role of the Hippo pathway transcriptional coactivators Yes‐associated protein (YAP) and transcriptional coactivator with PDZ‐binding motif (TAZ) in hepatocytes to facilitate cell–cell interactions...
Activation of apoptosis signal‐regulating kinase 1 (ASK1) is a key driving force of the progression of nonalcoholic steatohepatitis (NASH) and represents an attractive therapeutic target for NASH treatment. However, the molecular and cellular mechanisms underlying ASK1 activation in the pathogenesis of NASH remain incompletely understood. In this study, our data unequivocally indicated that hyperactivated...
Inhibition of apoptosis signal‐regulating kinase 1 (ASK1) activation has emerged as a promising target for the treatment of nonalcoholic steatohepatitis (NASH). Multiple forms of posttranslational modifications determine the activity of ASK1. In addition to phosphorylation, recent studies revealed that ubiquitination is essential for ASK1 activation. However, the endogenous factor that regulates ASK1...
