Because neither lmo1–/– nor TATA/TATAMYCN–expressing tumors appeared to be driven by the adrenergic CRC, which is preferred by neuroblastomas arising in the GATA/GATA background, we questioned whether either tumor type was instead driven by the mesenchymal CRC (6, 7, 10). The gene discussed is QRSL1; the disease is colorectal carcinoma.
