Across TCGA pan-cancer cohorts, LINC01591 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of LINC01591’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where LINC01591 RNA is repressed in tumor relative to normal tissue. In most cancer types LINC01591 is over-expressed in tumor, although a few such as BRCA and LUSC show the opposite, repressed pattern.
BRCA and LUSC are the cancer types where LINC01591 tumor–normal differential expression is most reproducible.
