STIP1 is overexpressed at both mRNA and protein levels in OSCC samples compared with normal tissues, similar as, for example, in gliomas (13), colorectal cancers (15), hepatocellular carcinoma (18), gastric cancers (20), cervical carcinomas (21), lung cancers (23), pancreatic cancers (36) and breast cancers (37). This evidence concerns the gene STIP1 and breast cancer.
