Across TCGA pan-cancer cohorts, LINC00345 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of LINC00345’s most consistent transcriptional readouts.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where LINC00345 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types LINC00345 is over-expressed in tumor, although a few such as BRCA and KICH show the opposite, repressed pattern.
LIHC, BRCA, and KICH are the cancer types where LINC00345 tumor–normal differential expression is most reproducible.
