Across TCGA pan-cancer cohorts, DENND4A mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of DENND4A’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where DENND4A mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types DENND4A is over-expressed in tumor, although a few such as LUAD and PDAC show the opposite, repressed pattern.
LUAD, CCRCC, and PDAC are the cancer types where DENND4A tumor–normal differential expression is most reproducible.
