Across TCGA pan-cancer cohorts, CTSZ RNA differs between tumor and matched normal tissue in 9 of 18 cancer types tested, making tumor–normal expression one of CTSZ’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where CTSZ RNA is more highly expressed in tumor relative to normal tissue. In most cancer types CTSZ is over-expressed in tumor, although a few such as LUSC and THCA show the opposite, repressed pattern.
KIRC, HNSC, and STAD are the cancer types where CTSZ 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 CTSZ RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
