Across TCGA pan-cancer cohorts, APBB1IP mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of APBB1IP’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where APBB1IP mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types APBB1IP is over-expressed in tumor, although a few such as LSCC and COAD show the opposite, repressed pattern.
CCRCC, PDAC, and LSCC are the cancer types where APBB1IP tumor–normal differential expression is most reproducible.
