In support of this, in a small cohort of lung cancer patients from the Human Protein Atlas database, STING protein was undetectable in 2 of 4 LUAD patients and 6 of 6 LUSC patients, whereas 3 of 3 normal lung tissues strongly expressed STING protein (P > 0.05 for LUAD, P < 0.01 for LUSC, Fig. 1c). The gene discussed is STING1; the disease is lung carcinoma.
