Across TCGA pan-cancer cohorts, RC3H1 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RC3H1’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where RC3H1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types RC3H1 is over-expressed in tumor, although a few such as HNSC and COAD show the opposite, repressed pattern.
HNSC, COAD, and CCRCC are the cancer types where RC3H1 tumor–normal differential expression is most reproducible.
