Across TCGA pan-cancer cohorts, A2ML1-AS2 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of A2ML1-AS2’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where A2ML1-AS2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types A2ML1-AS2 is over-expressed in tumor.
LUSC are the cancer types where A2ML1-AS2 tumor–normal differential expression is most reproducible.
