Gadolinium chloride ameliorates acute lung injury associated with severe acute pancreatitis in rats by regulating CYLD/NF-κB signaling.
The present study was embarked on an investigation of the mechanisms behind the effects of Gadolinium chloride (GdCl3) on lung injury associated with severe acute pancreatitis (SAP) in rats. Rats were randomly distributed into three groups: sham operation group (SO), SAP group and SAP treated with GdCl3 group (SAP + GdCl3). Retrograde injection of 5% sodium taurocholate into the biliopancreatic duct was adopted to induce SAP. ⋯ The NF-κB activation was obviously inhibited when CYLD expression was markedly up-regulated in AMs of SAP + GdCl3. Negative correlation was analyzed between CYLD and NF-κB in both SAP and SAP + GdCl3. These data demonstrate that GdCl3 ameliorates lung injury secondary to SAP in rats mainly by up-regulating CYLD expression and inhibiting NF-κB activation in AMs, which may play a vital role in lung injury.
