Across TCGA pan-cancer cohorts, CARS1 RNA differs between tumor and matched normal tissue in 15 of 18 cancer types tested, making tumor–normal expression one of CARS1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where CARS1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types CARS1 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
KIRC, HNSC, and COAD are the cancer types where CARS1 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 CARS1 RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
