This study aims to investigate the dynamic expression of Notch-1 and Jagged-1 in a rat liver fibrosis model and to explore their effects on this pathological process and their significance.Firstly, healthy rats were randomly divided into control group and experimental group. After inducing liver fibrosis with CCl4 in the experimental group, samples were taken at weeks 0, 4, 8, and 12, and changes in the gene and protein expression levels of Notch-1 and Jagged-1 were analyzed using 精品文档---下载后可任意编辑real-time fluorescence quantitative PCR and immunoblotting techniques.The results showed that after inducing liver fibrosis with CCl4, the gene exp...
