Negative regulation of cell growth and differentiation by TSG101 through association with p21(Cip1/WAF1).
TSG101 was discovered in a screen for tumor susceptibility genes and has since been shown to have a multiplicity of biological effects. However, the basis for TSG101's ability to regulate cell growth has not been elucidated. We report here that the TSG101 protein binds to the cyclin/cyclin-dependent kinase (CDK) inhibitor (CKI) p21(Cip1/WAF1) and increases stability of the p21 protein in HEK293...
متن کاملA Novel ASK Inhibitor AGI-1067 Inhibits TLR-4-Mediated Activation of ASK1 by Preventing Dissociation of Thioredoxin from ASK1.
The cell type that normally limits the inflammatory and atherosclerotic process is the vascular endothelial cell (EC) that can be regulated by proinflammatory and various stresses. Toll-like receptor-4 (TLR4) plays an important role in the pathogenesis of atherosclerosis, in part, by activating apoptosis signal-regulating kinase 1 (ASK1) to initiate the activation of MAP kinases pathways and th...
متن کاملWhy Believe That There Is a God?
This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...
متن کاملIdentification of a novel antiapoptotic protein that antagonizes ASK1 and CAD activities
Diverse stimuli initiate the activation of apoptotic signaling pathways that often causes nuclear DNA fragmentation. Here, we report a new antiapoptotic protein, a caspase-activated DNase (CAD) inhibitor that interacts with ASK1 (CIIA). CIIA, by binding to apoptosis signal-regulating kinase 1 (ASK1), inhibits oligomerization-induced ASK1 activation. CIIA also associates with CAD and inhibits th...
متن کاملLaminar flow inhibits TNF-induced ASK1 activation by preventing dissociation of ASK1 from its inhibitor 14-3-3.
The inflammatory cytokine TNF-alpha stimulates several presumed pro-atherogenic signaling events in endothelial cells (ECs), including activation of c-Jun NH(2)-terminal kinase (JNK) and induction of E-selectin. Here, we show that apoptosis signal-regulating kinase 1 (ASK1), a MAP kinase kinase kinase, is required for TNF-mediated JNK activation. TNF activates ASK1 in part by dissociating ASK1 ...
