Across TCGA pan-cancer cohorts, CAMK2N1 mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of CAMK2N1’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where CAMK2N1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types CAMK2N1 is over-expressed in tumor, although a few such as LSCC and LUAD show the opposite, repressed pattern.
LSCC, LUAD, and CCRCC are the cancer types where CAMK2N1 tumor–normal differential expression is most reproducible.
