Among tumors, TAP1 showed marked overexpression in cervical and endocervical cancers (CESC) and HNSC, relative to other tumors, while the greatest difference between normal and corresponding malignant tissues was detected in cholangiocarcinoma (CHOL), GBM, and pancreatic adenocarcinoma (PAAD). This evidence concerns the gene TAP1 and cervical squamous cell carcinoma.
