GO analysis demonstrated that genes (WNT9A, NOTCH3, SOCS1, MCL1, HIF1A, ALOX5, CD47, CXCR4, CDK9, HRAS, PLK3, ETS2 and RPL5) involved in “acute and chronic myeloid leukaemia,” “bladder cancer,” “hedgehog signalling pathway,” “endometrial cancer” and “basal cell carcinoma” signalling pathways were significantly correlated with the DDIT4 expression. The gene discussed is CXCR4; the disease is urinary bladder carcinoma.
