Across TCGA pan-cancer cohorts, RBMS3-AS1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RBMS3-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where RBMS3-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types RBMS3-AS1 is over-expressed in tumor, although a few such as LUSC and THCA show the opposite, repressed pattern.
LUSC and THCA are the cancer types where RBMS3-AS1 tumor–normal differential expression is most reproducible.
