Overexpressed genes were also associated with macrophage activation, disease‐free survival, response to treatment, protein transport, and prognosis in ADC (Figure 1E); DNA replication, calcium channels, S phase, estrogen receptor, and histone deacetylase in SCC (Figure 1F); immune response, heat shock protein, and SNPs in LCC (Figure 1G); or cell growth, mitosis, cell division, RNA interference, and lymph node metastasis in SCLC (Figure 1H). Here, ESR1 is linked to small cell lung carcinoma.
