LINC00644

Across TCGA pan-cancer cohorts, LINC00644 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of LINC00644’s most consistent transcriptional readouts.

The strongest signal is observed in breast invasive carcinoma (BRCA), where LINC00644 RNA is repressed in tumor relative to normal tissue. In most cancer types LINC00644 is over-expressed in tumor, although a few such as BRCA and PRAD show the opposite, repressed pattern.

BRCA, PRAD, and LUSC are the cancer types where LINC00644 tumor–normal differential expression is most reproducible.

RNA tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in LINC00644 RNA (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
