We and others have observed that advanced or late-stage NSCLC tumors expressed higher levels of CCL7 mRNA than did the early stage NSCLC tumors34, which might be due to enhanced genome instability or cell death in late-stage tumors that induces a CCL7-expressing proinflammatory condition in the TME in a JAK-STAT manner43–47. The gene discussed is CCL7; the disease is non-small cell lung carcinoma.
