Across TCGA pan-cancer cohorts, ARG1 RNA differs between tumor and matched normal tissue in 12 of 18 cancer types tested, making tumor–normal expression one of ARG1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where ARG1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types ARG1 is over-expressed in tumor, although a few such as THCA and LIHC show the opposite, repressed pattern.
KIRC, THCA, and LIHC are the cancer types where ARG1 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 ARG1 RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
