Across TCGA pan-cancer cohorts, LINC01440 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of LINC01440’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where LINC01440 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types LINC01440 is over-expressed in tumor, although a few such as BRCA show the opposite, repressed pattern.
KIRC and BRCA are the cancer types where LINC01440 tumor–normal differential expression is most reproducible.
