    ..In vitro-preprotein import into isolated mitochondria showed no apparent difference between Tom34(-/-) and wild-type mice. These results indicate that Tom34 is dispensable for mouse growth and development under optimal conditions. ..

    ..Instead they support the idea that factor(s) associated with central veins rather than humoral factors direct pericentral hepatocytes to express glutamine synthetase and to suppress carbamoylphosphate synthetase I expression. ..

    ..These results suggest that jvs affects not only the regulation of the tissue-specific expression of the urea cycle enzymes but also the regulation of their developmental induction. ..
