Recombinant human augmenter of liver regeneration may promote stromelysin-1 gene expression in experimental liver fibrosis / 中华传染病杂志

ABSTRACT

Objective To investigate the influence of recombinant human augmenter of liver rege neration (hALR) on stromelysin 1 gene expression in experimental liver fibrosis. Methods Two kinds of rat model of experimental liver fibrosis induced by CCl 4 and albumin were established and different dosages of recombinant human augmenter of liver regeneration were given during the process of model making. Total RNA of liver tissues was extracted and stromelysin 1 gene expression levels were measured by reverse transcription polymerase chain reaction (RT PCR). Results In both rat models of experimental liver fibrosis, stromelysin 1 gene expression levels in hALR treating group were significantly higher than those of model groups in different periods of model forming. Stromelysin 1 gene expression levels in high dose hALR treated group were significantly higher than those of low dose hALR treated group.Conclusion Recombinant human augmenter of liver regeneration may have effects of promoting gene expression of stromelysin 1 in experimental liver fibrosis.
