Across TCGA pan-cancer cohorts, ANXA8 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ANXA8’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where ANXA8 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types ANXA8 is over-expressed in tumor, although a few such as LUAD and HNSC show the opposite, repressed pattern.
LSCC, LUAD, and PDAC are the cancer types where ANXA8 tumor–normal differential expression is most reproducible.
