The relative mRNA level of GTPBP2 in the CRC tissue negatively correlated with mouse body weight and positively correlated with mean tumor volume but did not correlate with either tumor number or colon length (Supplementary Figs. 2B–2E), suggesting that GTPBP2 might enhance CRC growth. The gene discussed is GTPBP2; the disease is colorectal carcinoma.
