Expression patterns and action analysis of genes associated with physiological responses during rat liver regeneration: Cellular immune response

Figure 3 Expression similarity and time relevance clusters of 127 cellular immune response-associated genes during liver regeneration. Detection data of rat genome 230 2.0 array were analyzed by H-clustering. Red represents up-regulated genes chiefly associated with antigen processing and presentation; green represents down-regulated genes mainly associated with antigen elimination; black represents the genes whose expressions are meaningless. The upper and right trees showing the expression similarity cluster and time series cluster respectively, by which these genes can be classified into 5 and 14 groups, respectively.
