Gene expression profile in immunologically injured liver cell of mice |
| |
摘 要: | To study the gene expression profiles between immunologically injured liver cell and normal liver cell of mice and to screen on a large scale the differentially expressed genes associated with the formation of liver injury,the experimental mice were randomly divided into the normal group for controlling and the immunologically liver-injured group induced by BCG and LPS.The liver mRNA of the two groups were extracted respectively and reversely-transcribed to cDNA with the incorpora-tion of different fluorescence(Cy3,Cy5) labeled dUTP as the hybridization probes.The mixed probes were hybridized to the cDNA microarray chips.The fluorescent signal results were acquired by scanner ScanArray 4000 and analyzed with software GenePix Pro 3.0.Among the 14112 target genes,293 genes were found to be significantly differentially expressed,in which 188 genes were up-regulated and 105 genes were down-regulated.Based on the analysis of biological functions of those differentially expressed genes,it was indicated that the occurrence and development of mouse liver damage induced by BCG and LPS were highly correlated with the processes of immune reac-tions,cell synthesis,metabolism,apoptosis and transportation in liver cell,which might be quite im-portant for elucidating the regulatory network of gene expression associated with the liver damage,also important for finally discovering the pathogenic mechanisms of immunological liver damage.
