Objective: The protein kinases, PKR, and PERK have been implicated in pro-inflammatory cytokine-mediated cartilage degradation in vitro and endoplasmic reticulum stress-induced arthritis respectively. The objective of this study was to establish whether loss of P58IPK, an inhibitor of PKR and PERK, results in a degenerative joint phenotype in vivo.Methods: Sections of knee joints from P58IPK-null and wild-type mice...
