Research Abstract |
We previously performed a screen in medaka to isolate mutants with impaired liver development. The medaka hio mutants exhibit a profound (but transient) defect in liver specification that resembles the liver formation defect found in the zebrafish prometheus (prt) mutants, whose mutation occurs in the wnt2bb gene. Positional cloning revealed that the hio mutation affects the raldh2 gene encoding retinaldehyde dehydrogenase type2 (RALDH2), the enzyme principally responsible for retinoic acid (RA) biosynthesis. Our data reveal the unexpected finding that RA signaling positively regulates the wnt2bb gene expression required for liver specification in medaka. Furthermore, we have succeeded in isolating ken mutation that models human disease non-alcoholic steatohepatitis (NASH). NASH are serious human diseases in the modern world, so ken mutation may shed a new light on the molecular mechanisms of these diseases and the preventive medicine.
