Across TCGA pan-cancer cohorts, SPINT4 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of SPINT4’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where SPINT4 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types SPINT4 is over-expressed in tumor.
LUAD are the cancer types where SPINT4 tumor–normal differential expression is most reproducible.
