From: Germ cell and tumor associated piRNAs in the medaka and Xiphophorus melanoma models
Row wise scaled heatplot of normalized expression levels of piRNA clusters: Diffenertially expressed piRNA clusters with fold change > 4-fold and p.value < 0.05 between tumor and HP in medaka or malignant and benign in Xiphophorus. In addition the corresponding expression levels of normal skin is shown. piRNA clusters are both up and down regulated. In both fish there is a large amount of clusters showing a much higher expression level in skin than in any other somatic tissue measured
