Compared with those in the WT mice, the average tumor weight (P < 0.05) (Figure 6G), volume (P < 0.05) (Figure 6H), and body weight (P < 0.05) (Figure 6I) in ST2−/− mice were lower, but the opposite effects were observed in the IL-33-overexpression group (P < 0.05) (Figure 6K–6M). The gene discussed is IL33; the disease is neoplasm.
