| Outline of Final Research Achievements |
To identify the molecular mechanism that statin, a therapeutic agent for dyslipidemia, causes rhabdomyolysis, we generated skeletal muscle specific HMGCR KO (mKO) mice. These mice exhibited deficient of cholesterol synthesis leading to rhabdomyolysis. However, these mice had higher cholesterol contents in skeletal muscle than WT mice. Next, we generated LDLR KO/ mKO mice, which could not synthesize cholesterol de novo and import cholesterol from extracellular system. LDLR KO/ mKO mice had same phenotypes as mKO mice, thereby proposing that there is an unknown mechanism for cholesterol metabolism.
