Across TCGA pan-cancer cohorts, OOEPP1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OOEPP1’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where OOEPP1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OOEPP1 is over-expressed in tumor.
STAD and ESCA are the cancer types where OOEPP1 tumor–normal differential expression is most reproducible.
