Differentially expressed miRNAs from two sets of microarray profiling. Unsupervised hierarchical cluster analysis for differentially expressed miRNAs identified as significant by t-test (P<0.05) provided by microarray profiling: (A) Set 1 (No., BH13053) comprised of 7 GC cases and 8 normal controls and (B) Set 2 (No., BH13333) comprised of 9 GC cases and 10 normal controls. Samples are shown in columns and miRNAs in rows. The insets are color keys indicating the range of normalized log₂-based signals and the histograms of the signals. (C) Two-way Venn diagram indicating the numbers of differentially expressed miRNAs (P<0.05) in Set 1 (a) and Set 2 (b).
