NOS1

Across TCGA pan-cancer cohorts, NOS1 mass-spec protein differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of NOS1’s most consistent transcriptional readouts.

The strongest signal is observed in colon adenocarcinoma (COAD), where NOS1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types NOS1 is over-expressed in tumor, although a few such as COAD and LUAD show the opposite, repressed pattern.

COAD, LUAD, and HNSC are the cancer types where NOS1 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 NOS1 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
