ARSA

Across TCGA pan-cancer cohorts, ARSA mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of ARSA’s most consistent transcriptional readouts.

The strongest signal is observed in colon adenocarcinoma (COAD), where ARSA mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ARSA is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.

COAD and LUAD are the cancer types where ARSA tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in ARSA mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
