Across TCGA pan-cancer cohorts, DENND5B mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of DENND5B’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where DENND5B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types DENND5B is over-expressed in tumor, although a few such as LUAD and OV show the opposite, repressed pattern.
LUAD, OV, and PDAC are the cancer types where DENND5B tumor–normal differential expression is most reproducible.
