Abstract:
Objective To construct a mouse model for real-time,noninvasive and specific monitoring of inflammation activation in hepatic tissues.Methods An inflammation reporter gene was targeted to the liver by hydrodynamic gene delivery technology.Bioluminescence imaging was used to detect the firefly luciferase(Fluc) expression in the mouse liver after inflammatory stimulation.Besides,the relevance between the light intensity and inflammation level was also intensively investigated.Results pIL-6-Fluc was successfully delivered to the liver.The hydrodynamic gene delivery could cause a transient liver injury that could return normal in 5 to 7 days.The expression of pIL-6-Fluc could be induced by lipopolysaccharides(LPS) treatment with an about (46.80±13.35) fold increase at the peak value,which was significantly higher than that detected by ELISA [(4.09±0.96)fold].Conclusion An inflammation reporter mouse model is constructed in this study by hydrodynamic gene transfection,allowing noninvasive monitoring of inflammation activation specifically in hepatic tissues.The reporter model is capable of monitoring inflammation activation with a sensitivity higher than that of ELISA.
