Across TCGA pan-cancer cohorts, OR1P1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of OR1P1’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where OR1P1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR1P1 is over-expressed in tumor.
HNSC, LUSC, and THCA are the cancer types where OR1P1 tumor–normal differential expression is most reproducible.
