Fishing for new models of liver disease
Zebrafish research has already yielded important insights into vertebrate
development and human disease, and might now be able to add liver disease to
its list of achievements. On
p. 3561, Sadler et
al. describe how they screened 297 zebrafish lines carrying mutations in genes
essential for embryonic development for an enlarged liver (hepatomegaly),
which is a sign of many liver disorders. From this screen, they identified
seven mutants with hepatomegaly, three of which (vps18, nf2 and
foie gras) have phenotypes resembling human liver diseases, namely
human arthrogryposis-renal dysfunction-cholestasis syndrome (vps18),
choledochal cyst formation (nf2) and fatty liver disease (foie
gras). These mutants should provide valuable models for the future study
of liver development, and for the investigation of the molecular pathogenesis
of congentital biliary disorders and of the common human disorder fatty liver
disease.
