Across TCGA pan-cancer cohorts, C9orf116 mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of C9orf116’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where C9orf116 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types C9orf116 is over-expressed in tumor, although a few such as LUAD show the opposite, repressed pattern.
LUAD are the cancer types where C9orf116 tumor–normal differential expression is most reproducible.
