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