Analysis of TCGA gene expression in lung cancer revealed that HB-EGF expression in LUAD and LUSC had no or negative correlation with the markers of T cells, B cells, mast cells, and NK cells (Figures 2A–D) and are mostly positively correlated with the markers of neutrophils, monocytes, and DCs (Figures 2E–H). The gene discussed is HBEGF; the disease is lung carcinoma.
