FPKM‐normalized RNA‐seq. data of the TCGA Research Network (TCGA‐COAD;
http://cancergenome.nih.gov/; 09/25/2017) were log‐transformed to illustrate the relative expression of (A) Wnt3 and (B) Evi in healthy colon (41) versus colon adenocarcinoma (456). The distribution into tumor and healthy samples was based on their barcodes as described in TCGA Wiki. Statistical significance of gene expression differences was determined using a Student's
t‐test under the alternative hypothesis H
1 that gene expression is higher in tumors compared to healthy tissue. The boxplot diagram shows the median as line within the box, the 25
th and 75
th percentiles as the upper and lower part of the box, the 10
th and 90
th percentiles as error bars and outliers as circles.
