PEMT

Across TCGA pan-cancer cohorts, PEMT mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of PEMT’s most consistent transcriptional readouts.

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

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