Importantly, treatment of JAK1 inhibitor in KP mice significantly downregulated the mRNA levels of Ccl7 in the lungs at 8 weeks after tumor induction (Supplementary Fig. 3e), suggesting that CCL7 is upregulated in the tumor-burdened lungs in KP mouse model in a JAK-STAT-dependent manner. The gene discussed is JAK1; the disease is neoplasm.
