The Wilcoxon tests discovered that 10 cancer Hallmark pathways were differentially expressed between two subtypes, which included glycolysis, hypoxia, IL2-STAT5-signaling, ILl6-JAK-STAT5 signaling, MTORC1 signaling, notch signaling, peroxisome, reactive oxygen species pathway, spermatogenesis, and unfolded protein response. Here, IL2 is linked to cancer.
