The strict requirement of Notch signaling for hepatocyte reprogramming and iCCA formation was confirmed in other studies utilizing R26RYFP–based, AAV8-Tbg-Cre infection-initiated hepatocyte lineage tracing combined with tumorigenesis triggered by HDTV injection of activated forms of AKT (myr-AKT) and Yap (YapS127A) oncogenes [61]. This evidence concerns the gene SERPINA7 and infection.
