title: [Changes of gene expression profiles in CCl4 injured liver of mice].
abstract: OBJECTIVE
  To study the gene expression profiles between the CCl4 injured liver and normal liver in mice, and to screen the differentially expressed genes that relate to liver injury by CCl4 on a large scale using cDNA microarrays.
  
  
  METHODS
  Male Kunming strain mice were divided into two groups: one was control group and another was CCl4 injured liver group that was given 0.1% CCI4 oil solution ip at dose of 10 mL x kg(-1) every three days, totally for ten times. Then mRNA in livers of the two groups of mice was extracted, separately, and reversely transcribed to cDNA with the incorporation of different fluorescent-labeled dUTP as the hybridization probes. The mixed probes were hybridized to the cDNA microarrays. The fluorescent signal values were acquired by scanner and analyzed with statistical software.
  
  
  RESULTS
  Among the 14 100 target genes, 379 genes were differentially expressed, in which 163 genes were up-regulated and the other 216 genes were down-regulated. They are closely related to a range of biological functions.
  
  
  CONCLUSIONS
  Using the cDNA microarray and experimental animal modeling technique, the differentially expressed genes of CCl4 injured liver in mice on a large scale could be studied. It is useful for further investigation of the injury mechanism of CCl4.
