STEAP3-AS1 is an antisense lncRNA of six-transmembrane epithelial antigen of the prostate 3 (STEAP3, also known as TSAP6 or dudulin-2), which was initially identified as a potential prognostic biomarker in tongue squamous cell carcinoma (TSCC) [45]. This evidence concerns the gene STEAP3 and tongue squamous cell carcinoma.
