Figure 4From: Genomic analysis of microRNA time-course expression in liver of mice treated with genotoxic carcinogen N-ethyl-N-nitrosoureaHierarchical clustering analysis of 43 deferentially expressed miRNAs. Fold change for each miRNA at each time point after ENU treatment was determined relative to the vehicle-treated controls and logarithmically transformed (base 2). Hierarchical cluster analysis was conducted using a Euclidean distance-calculating and Ward linking method. Up-regulated miRNAs are shown in red; down-regulated miRNAs in green; and no-changes in black. Four clustering groups were identified and named as I, II, III, and IV, respectively.Back to article page
