Across TCGA pan-cancer cohorts, LINC01919 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of LINC01919’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where LINC01919 RNA is repressed in tumor relative to normal tissue. In most cancer types LINC01919 is over-expressed in tumor, although a few such as LUSC and LUAD show the opposite, repressed pattern.
LUSC, LUAD, and STAD are the cancer types where LINC01919 tumor–normal differential expression is most reproducible.
