肌原纤维细胞(myofibroblast)在愈伤反应(wound-healing response)中扮演十分重要角色.而当机体组织受损时,组织内预应力环境将被破坏,出现不同程度的应力集中和应力松弛,从而影响细胞骨架张力,而骨架张力可以转化为细胞信号事件,针对组织预应力和Rho信号与肌原纤维细胞分化之间的关系进行探讨. 相似文献

The cancer-testis antigen 23 (CT23) gene has been reported in association with the pathogenesis and progress of hepatocellular carcinoma (HCC). However, the alterations of gene expression profiling induced by CT23 knockdown in HCC cells remains largely unknown. In this study, the RNA interfering (RNAi) method was used to silence CT23 expression in BEL-7404 cells. Microarray analysis was performed on mRNA extracted from the CT23 knockdown cells and the control cells to determine the alterations of gene expression profiles. The result showed a total of 1051 genes expressed differentially (two-fold change), including 470 genes upregulated and 581 gene downregulated in the CT23 knockdown cells. A bioinformatic analysis showed that the functional differentially expressed genes (DEGs) were linked to cell proliferation, migration, and apoptosis, and metallothionein 1 (MT1) attained the maximum enrichment scores in functional annotation, classification, and pathway analysis of DEGs. Furthermore, Western blot analysis and cell behaviors assays verified that CT23 modulates cell proliferation, migration, and apoptosis by regulating MT1 expression in HCC cells and non-neoplastic hepatocytes. In summary, downregulated CT23 gene in BEL-7404 cells might change the expressions of carcinogenesis and progression related genes in HCC by upregulating MT1 expression, which would provide insight into searching for a novel therapeutic target for HCC. 相似文献
