Figure Lengend Snippet: A . Unsupervised clustering of the 45 samples of this study by log 2 -transformed microarray signal values of all 395 expressed microRNAs. The numbers indicate identities of the 45 subjects, with cases (n = 22) and controls (n = 23) shown in black and grey, respectively. The sample tree with optimized leaf-ordering is drawn using Pearson correlation for distance metric and average linkage for cluster-to-cluster distance, and the scale for it represents node-heights. B . Supervised clustering of microRNAs by their log 2 -transformed microarray signal values. The heat-map, with the pseudo-color scale underneath, shows log 2 -transformed microarray signal values of the 43 microRNAs whose expression is altered >25% in either direction in the cases compared to the controls. The gene tree is drawn as in A .

Figure Lengend Snippet: A . Receiver operating characteristic curves, the areas under curve ( AUC ) for age, and the line of identity, x = y , with an AUC of 0.5, are shown. B . Correlation with microRNA expression. Values for the clinical variables were correlated with microarray signal values for the 395 expressed microRNAs (n = 45 for age; n = 39 for others). The curves depict frequency histograms of Pearson correlation coefficients ( r ) with a bin of 0.025. Curves were smoothened using four neighbors for averaging and a zero order polynomial. Correlations are also shown for the random variable resampled WBC count for which values were generated by resampling the WBC count data.

Figure Lengend Snippet: Microarray interplatform analysis . (A) Overlap of unique and named genes shared among the 3 microarray platforms used in this study. The pool of 17070 shared genes was used for further cross-platform analysis. The total numbers of genes for each platform and for all platforms combined are indicated. (B) Overlap of significantly regulated genes at 6 h after EGF treatment considering each of the 3 microarray platforms independently.

Figure Lengend Snippet: GSEA analysis on significantly regulated gene sets across microarray platforms . Profile of the Running ES Score & Positions of Gene Set Members on the Rank Ordered List using 6 h EGF treatment data according to each of the three microarray platforms. In each panel, the vertical black lines indicate the position of each of the genes of the tested gene set in the reference data set (ranked by average of the three respective EGF versus control log2ratios of replicate experiments). The green curve plots the ES (enrichment score), which is the running sum of the weighted enrichment score obtained from GSEA software. Within each queried gene set, the farther the position of a gene to the left (red) implies a higher correlation with EGF up-regulated genes in the reference platform, and the farther to the right (blue) implies a higher correlation with genes down-regulated upon EGF treatment in the reference platform. Studied gene sets correspond to lists of up- or down-regulated genes in each platform at 6 h of EGF treatment. Significantly enriched data sets are defined according to GSEA default settings (p < 0.001 and a false discovery rate (FDR) < 0.25). R.L.M = ranked list metric.

Figure Lengend Snippet: Correlation between microarrays and Illumina GA-I sequencing . (A) Comparison of estimated log2ratios from DGE ( Y -axis) and the mean of all microarray platforms ( X -axis). We consider only genes that were interrogated using all platforms and genes with a mean number of counts across lanes greater than 0. Genes with counts greater than 32 reads (colored red or green) or less than (black) 32 reads in at least one sample are shown. (Red dots) Genes called differentially expressed based on DGE data at an 10% FDR by RankProd. (Green dots) Genes not called as differentially expressed but above 32 counts. (Inset box) Correlation between technologies is higher when considering genes above the 32 count detection level (0.57) than when all genes are included (0.49). (B-C) Concordance at the top (CAT) plots of the different platforms with the 500 top genes from a reference platform, shown for Agilent in (B) and DGE in (C). See inset box for color codes identifying each platforms compared to the remaining platform used as reference. (D) Correlation plots with regression lines between log2ratios of the five high content platforms measurements (Y-axis) and quantitative real time PCR results using SYBR green assays (X-axis), based on measurements for 21 genes at the 6 h time point (see Additional file , Table S1).
