Across TCGA pan-cancer cohorts, OTUD7B mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of OTUD7B’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where OTUD7B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types OTUD7B is over-expressed in tumor, although a few such as COAD and LUAD show the opposite, repressed pattern.
COAD, LUAD, and HNSC are the cancer types where OTUD7B tumor–normal differential expression is most reproducible.
