To further validate the relationship between tumoural UBA6 protein expression and immunotherapy responses in other cancer patients, we measured UAB6 protein expression pattern and CD8+ T cells infiltration in tumour tissues collected from a cohort of cancer patients (n = 22) enroled in a basket trial of anti-PD1 treatment, which included oesophageal cancer, lung cancer, stomach cancer, and colon cancer patients. The gene discussed is UBA6; the disease is lung cancer.
