Across TCGA pan-cancer cohorts, ATG2B mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ATG2B’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where ATG2B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ATG2B is over-expressed in tumor, although a few such as CCRCC and PDAC show the opposite, repressed pattern.
CCRCC, PDAC, and LSCC are the cancer types where ATG2B tumor–normal differential expression is most reproducible.
