In this study, we analyzed the data derived from TCGA database and GTEx database and found that TAP1 expression was elevated in lung cancer, breast cancer, pancreatic cancer, renal cell carcinoma, and other tumors and was correlated with the survival state of patients, which was consistent with the findings reported previously (Xu et al., 2013; Xu et al., 2019). Here, TAP1 is linked to lung carcinoma.
