Objective To observe the effects of transforming growth factor β type I receptor (TβRI) anti-sense RNA and tissue inhibitor of metalloproteinase 1 (TIMP-1) antisense RNA on experimental liver fibrosis in rats. Methods TβRI and TIMP-1 antisense RNA eukaryotic expression plasmids were constructed and transfected into experimental rats with hepatic fibrosis. The impacts of TβRI and TIMP-1 antisense RNA on TIMP-1,TβRI and MMP-13 expression were detected by Western blot. Results The relative expressions of TIMP-1 protein in normal control group,antisense TβRI group,antisense TIMP-1 group,combinational group,plasmid group and model group were (23.6±2.8),(57.96±3.8),(62.3±2.8),(34.2±2.8),(279.2±29.8)and (287.3±23.7),respectively;the relative expressions of TβRI in each groups were (56.2 ±2.7),(70.5. ±1.8),(77.0 ±1.7),(60.6 ±2.2),(232.0 ±19.4) and(241.0±18.3),respectively;and the relative expressions of MMP-13 were (17.84±2.3),(36.2±3.7),(41.3±2.4), (28.6±2.0),(127.3±1.2)and (118.5±2.5),respectively. The relative expressions of TβRI,TIMP-1 and MMP-13 in antisense TβRI group, antisense TIMP-1 group and combinational group were significantly decreased compared with normal control group and plasmid group(P<0.05),while there was no significantly differences between plasmid and model group. Conclusions Antisense TβRI RNA and antisense TIMP-1 RNA can both inhibit the expres-sions of TβRI,TIMP-1 and MMP-13 protein effectively,and their combination can improve the inhibiting effects.
