Heat map representation of all miRNAs present on the microarray. The heat map illustrates the expression differences of all miRNAs on the microarray between xlpra2-mutants vs. normals at the 3 tested ages (3, 7, and 16 wks). miRNAs are listed from the highest to the lowest fold change difference at 16 wks. The x-axis shows the ages, while the y-axis displays the different miRNAs. The map contains log2 intensity/fold change ratios that are color coded with red corresponding to up-regulation and blue to down-regulation.
