Abstract:
Objective To investigate the influence of recombinant human augmenter of liver regeneration (hALR) on gelatinase A(MMP 2) gene expression in experimental liver fibrosis. Methods Two kinds of animal model of rat experimental liver fibrosis induced by CCl 4 and albumin were established and different dosage of hALR (10,50 ?g?kg -1 ?d -1 )was given during the process of model making. Total RNA of liver tissues was isolated and MMP 2 gene expression levels were measured by reverse transcription polymerase chain reaction (RT PCR). Results In both rat models of experimental liver fibrosis, MMP 2 gene expression levels in two hALR preventing group were significantly lower than those of model group in different periods of model forming. MMP 2 gene expression levels in high dose of hALR treating group were significanfly lower than those of low dose hALR treating group. Conclusion hALR may have an effect on inhibiting gene expression of MMP 2 in experimental liver fibrosis.
