Across TCGA pan-cancer cohorts, LINC02220 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of LINC02220’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where LINC02220 RNA is repressed in tumor relative to normal tissue. In most cancer types LINC02220 is over-expressed in tumor, although a few such as KICH and KIRC show the opposite, repressed pattern.
KICH, LUSC, and KIRC are the cancer types where LINC02220 tumor–normal differential expression is most reproducible.
