Across TCGA pan-cancer cohorts, SPACA5 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SPACA5’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where SPACA5 RNA is repressed in tumor relative to normal tissue. In most cancer types SPACA5 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
THCA and BRCA are the cancer types where SPACA5 tumor–normal differential expression is most reproducible.
