Zusammenfassung
The liver specific expression of enzymes under normal conditions and in pathological situations is still enigmatic. Recently, the phenomenon of differential expression of enzymes along the porto-central axis of the liver acinus was demonstrated to be dependent on signal transduction pathways that are also important for the development of hepatocellular carcinoma (HCC). Most attention was drawn on the wnt-signaling pathway and its components beta-catenin and APC. Interestingly, the most prominent example of zonated expression in the normal liver –that of glutamine synthetase (GS) around the central veins- was sho…
