Across TCGA pan-cancer cohorts, SLC35F2 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SLC35F2’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where SLC35F2 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types SLC35F2 is over-expressed in tumor, although a few such as CCRCC show the opposite, repressed pattern.
CCRCC and HNSC are the cancer types where SLC35F2 tumor–normal differential expression is most reproducible.
