FABP4 and prostate carcinoma: Among transcripts with a higher expression in MLL- vs. AT1-tumors we found, for example, Pi15 –a gene associated with lethal prostate cancer in patients [36, 37], Fabp4 –a factor associated with bone metastases in prostate cancer patients [38], and Eya2 –a transcription factor associated with prostate development as well as metastasis in other cancer types [39, 40].
