IL32 and lung carcinoma: To determine the specificity of IL32 up‐regulation in PCs, we performed IL32 ELISA assays on conditioned medium (CM) harvested from normal fibroblasts (NFs), human umbilical vein endothelial cells (ECs), EGFR mutated lung cancer cell lines HCC827, PC9 and NCI‐H1975 (T790M+ cells), and primary PCs, revealing a significant increase in the secretion of IL32 in PC‐CM compared to that from NFs, ECs, or cancer cells (Figure 1G).
