Across TCGA pan-cancer cohorts, SGK3 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SGK3’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where SGK3 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types SGK3 is over-expressed in tumor, although a few such as CCRCC show the opposite, repressed pattern.
CCRCC and HNSC are the cancer types where SGK3 tumor–normal differential expression is most reproducible.
