Across TCGA pan-cancer cohorts, ISCA1P2 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of ISCA1P2’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where ISCA1P2 RNA is repressed in tumor relative to normal tissue. In most cancer types ISCA1P2 is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
COAD are the cancer types where ISCA1P2 tumor–normal differential expression is most reproducible.
