Solute carrier family 25 member 19 (SLC25A19) is a transporter protein of thiamine pyrophosphate across cellular membranes, which is needed as a cofactor for multiple metabolic enzymes and is important for homeostasis regulation. It was hypothesized that SLC25A19 may be a pan-cancer marker and a therapeutic target, and more concretely in hepatocellular carcinoma (HCC).
