Across TCGA pan-cancer cohorts, MAPK1IP1L mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MAPK1IP1L’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where MAPK1IP1L mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types MAPK1IP1L is over-expressed in tumor, although a few such as LSCC show the opposite, repressed pattern.
LSCC, LUAD, and HNSC are the cancer types where MAPK1IP1L tumor–normal differential expression is most reproducible.
