| Abstract: | Previous investigations demonstrated that carbamoyl-phosphate synthase II (synthase II) (EC 6.3.5.5) activity, amount, and in vivo synthetic rate increased approximately 9-fold in the rapidly proliferating rat hepatoma 3924A compared to normal liver. This study provides evidence by Northern and RNA dot blot hybridizations of a 13-fold increase in the amount of hepatoma 3924A synthase II mRNA compared to levels in normal liver. Southern and DNA dot blots indicated amplification of CAD hepatoma 3924A synthase II gene product. |
