Across TCGA pan-cancer cohorts, GLCCI1 mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of GLCCI1’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where GLCCI1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types GLCCI1 is over-expressed in tumor, although a few such as LSCC and PDAC show the opposite, repressed pattern.
CCRCC, LSCC, and PDAC are the cancer types where GLCCI1 tumor–normal differential expression is most reproducible.
