Outline of Final Research Achievements

We performed tracer studies using stable isotope technology in order to assess in vivo kinetics of apoB in 2 homozygous FH patients with PCSK9 gene mutation (E32K). In vivo kinetic study revealed that VLDL, IDL, and LDL apoB FCR were markedly delayed as compared with controls. With regard to production rates, VLDL and IDL PR were increased, but LDL apoB PR remained unchanged. Finally, analysis of metabolic channeling demonstrated that VLDL tended to be metabolized to remnant before converting to IDL. In one patient, atorovastatin was administrated and tracer study was repeated under medication. Atorvastatin significantly improved VLDL catabolism and completely normalized IDL and LDL FCR, but imcreased VLDL remnant formation remained unchanged. In summary, tracer study revealed that FH with PCSK9 gene mutation have apoB metabolic abnormalities distinct from those with LDL receptor gene mutations.
