In the ADRB2 high-expression group, ADRB2 associated genes were significantly enriched in immune signaling pathways (such as B cell receptor signaling pathway, T cell receptor signaling pathway, and NSCLC, NK-cell-mediated cytotoxicity, chemokine signaling pathway, and Jak STAT signaling pathway), in KEGG analysis. Here, ADRB2 is linked to non-small cell lung carcinoma.
