Across TCGA pan-cancer cohorts, LINC01646 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of LINC01646’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where LINC01646 RNA is repressed in tumor relative to normal tissue. In most cancer types LINC01646 is over-expressed in tumor, although a few such as THCA and KIRP show the opposite, repressed pattern.
THCA, KIRP, and KICH are the cancer types where LINC01646 tumor–normal differential expression is most reproducible.
