In the 'N-Akt' mouse liver cancer tumor model, elevated levels of Yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) were observed within the N-Akt tumor cells, with substantial YAP expression also noted in the hepatocytes adjacent to the N-Akt tumor cells. The gene discussed is AKT1; the disease is neoplasm.
