Furthermore, the normalized levels of IL-33 in the tumor tissuehomogenates were positively associated with the tumor size of tumor-bearing mice(r = 0.941, P < .05), while the normalized levelsof sST2 were negatively associated with the tumor size (r = −0.786,P < .05; Figure 1Iand J). The gene discussed is IL33; the disease is neoplasm.
