Does protein kinase R mediate TNF-α- and ceramide-induced increases in expression and activation of matrix metalloproteinases in articular cartilage by a novel mechanism?
We investigated the role of the proinflammatory cytokine TNF-α, the second messenger C(2)-ceramide, and protein kinase R (PKR) in bovine articular cartilage degradation. Bovine articular cartilage explants were stimulated with C(2)-ceramide or TNF-α for 24 hours. To inhibit the activation of PKR, 2-...
