Across TCGA pan-cancer cohorts, TSIX RNA differs between tumor and matched normal tissue in 7 of 18 cancer types tested, making tumor–normal expression one of TSIX’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where TSIX RNA is more highly expressed in tumor relative to normal tissue. In most cancer types TSIX is over-expressed in tumor, although a few such as THCA and KICH show the opposite, repressed pattern.
HNSC, THCA, and KICH are the cancer types where TSIX tumor–normal differential expression is most reproducible.
RNA tumor vs normal associations by lineage
Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in TSIX RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
