Across TCGA pan-cancer cohorts, LOXL1 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of LOXL1’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where LOXL1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types LOXL1 is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
PDAC and COAD are the cancer types where LOXL1 tumor–normal differential expression is most reproducible.
