In boys, “Pathways in cancer” is the only significant KEGG biological pathway at the 5% level and the top GO terms include “Negative regulation of transcription DNA-templated" (P = 1 × 10−4), “Positive regulation of tyrosine phosphorylation of Stat3 protein” (P = 0.020), “Negative regulation of transcription from RNA polymerase II promoter” (P = 0.031), “Regulation of cell shape” (P = 0.035), and “Hemopoiesis” (P = 0.036). Here, STAT3 is linked to cancer.
