Liver cirrhosis is the final stage of chronic liver disease and can be life-threatening. Despite extensive studies on its treatment, a standard therapy is yet to be developed. Considering the complex mechanism of fibrogenic and fibrolytic processes in liver cirrhosis, combined therapy may have clinically significant effects on cirrhotic livers. In this study, we used thioacetamide (TAA) administration and matrix metalloproteinase-13 (MMP13) gene delivery to induce extracellular matrix generation and degradation in rats. The aim of this study was to determine whether hydrodynamics-based gene delivery of MMP13 to cirrhotic liver has regressive and suppressive effects on fibrogenesis. MMP13-encoding plasmids were hydrodynamically delivered to TAA-induced cirrhotic livers, and intravascular pressure was monitored. Therapeutic effect with and without continuous TAA exposure was assessed 8 weeks after the gene delivery. Test results indicated successful gene delivery and gene expression in the cirrhotic livers. Furthermore, microscopic imaging showed that MMP13 delivery resulted in significant degradation of fibrotic areas. Quantitative analysis of hydroxyproline content supported the microscopic findings. These results suggest that transgene delivery of MMP13 can be a promising candidate to treat liver fibrosis and that hydrodynamics-based gene delivery can be a good option for delivery of MMP13 to cirrhotic livers.
