Our previous research highlighted the clinical relevance of transcription factor JunB (JUNB), C‐X‐C chemokine receptor type 4 (CXCR4), and programmed cell death 1 ligand 1 (PD‐L1) in breast and non‐small cell lung cancer (NSCLC) patients. The gene discussed is CD274; the disease is non-small cell lung carcinoma.
