Across TCGA pan-cancer cohorts, ATP11C mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of ATP11C’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where ATP11C mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ATP11C is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
COAD, LSCC, and HNSC are the cancer types where ATP11C tumor–normal differential expression is most reproducible.
