Across TCGA pan-cancer cohorts, LINC00561 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of LINC00561’s most consistent transcriptional readouts.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where LINC00561 RNA is repressed in tumor relative to normal tissue. In most cancer types LINC00561 is over-expressed in tumor, although a few such as BLCA and HNSC show the opposite, repressed pattern.
BLCA, HNSC, and BRCA are the cancer types where LINC00561 tumor–normal differential expression is most reproducible.
