Across TCGA pan-cancer cohorts, ACVR2A mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of ACVR2A’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where ACVR2A mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types ACVR2A is over-expressed in tumor, although a few such as LUAD and LSCC show the opposite, repressed pattern.
PDAC, LUAD, and LSCC are the cancer types where ACVR2A tumor–normal differential expression is most reproducible.
