Differential gene expression analysis of pediatric atypical teratoid tumors. A Heat map depicting gene expression from 13 AT/RT cases and normal brain (columns; ordered automatically by hierarchical clustering). A gradient “heat spectrum” appears at the right; red indicates increased expression, whereas blue denotes decreased levels. B Heat map illustrating the expression of 50 mRNAs. C Heat map illustrating the expression of 21 differentially expressed miRNAs (fold change > 2 and P-value < 0.01)
