ABSTRACT
AIM:
To investigate the transfection efficiency of mouse liver with non-viral vector containing manganese superoxide dismutase (Mn-SOD) gene.METHODS:
The eukaryotic expression vector, gWiz/Mn-SOD, encoding human manganese superoxide dismutase was constructed. The plasmids of gWiz/Mn-SOD were mixed with cationic lipids, followed by injection into mice via branch of superior mesenteric vein, to induce Mn-SOD over-expression in murine liver detected by RT-PCR, Western blotting, SOD activity and immunohistochemical staining.RESULTS:
gWiz/Mn-SOD transfection resulted in the obvious expression of exogenous Mn-SOD mRNA and protein in hepatic tissues at 8 hours after injection, and elevated mitochondria SOD activity 8.4 times in transfected hepatocytes than that in non-transfected cells at 72 hours after injection. It was showed that nearly 70% of mouse hepatocytes was obviously Mn-SOD positive after transfection.CONCLUSION:
High expression efficiency of Mn-SOD gene in mouse liver is achieved safely by injection of gWiz/Mn-SOD and cationic lipid mixture into branch of superior mesenteric vein. [
