WebMar 18, 2013 · This effect may be due to intracellular cholesterol depletion caused by statin‐induced activation of SREBP‐2, which, in turn, upregulates expression of both the LDL receptor and PCSK9 genes, leading to elevated circulating levels of PCSK9. 25 Interestingly, PCSK9 levels increased variably in response to statin therapy in only 50% of HoFH ... WebApr 1, 2005 · Statins, a class of drugs that inhibit cholesterol synthesis, increase expression of sterol regulatory element-binding protein-2 (SREBP-2), a transcription factor that activates both the Ldlr and Pcsk9 genes. Statin administration to Pcsk9–/– mice produced an exaggerated increase in LDLRs in liver and enhanced LDL clearance from plasma.

WebTo confirm that statins inhibit IDOL expression, serum levels of IDOL and PCSK9 were measured in 32 FH subjects before and at least 4 months after starting statin therapy.
