Long-chain fatty acid transport

Across TCGA pan-cancer cohorts, RNA activity of the Long-chain fatty acid transport pathway differs between tumor and matched normal tissue in 14 of the 18 cancer types tested.

The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where pathway activity is lower in tumor tissue than in matched normal tissue. In most cancer types, this pathway shows higher activity in tumors, although a few cancer types, such as KIRP and COAD, show the opposite pattern, with lower activity in tumor tissue.

KIRP, COAD, and LUAD show the most reproducible tumor–normal differences in pathway activity.

Tumor vs normal pathway activity by lineage

Ranked by sampling consensus. Activity change represents the tumor-versus-normal difference in pathway activity on a log₂ scale. Positive values indicate higher pathway activity in tumor tissue. The reported p-values are derived from the corresponding differential activity tests.
