Across TCGA pan-cancer cohorts, TBC1D26-AS1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of TBC1D26-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where TBC1D26-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types TBC1D26-AS1 is over-expressed in tumor, although a few such as LUAD and LUSC show the opposite, repressed pattern.
LUAD, LUSC, and UCEC are the cancer types where TBC1D26-AS1 tumor–normal differential expression is most reproducible.
