Atorvastatin 47-59 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 24-32 21123766-6 2011 Atorvastatin significantly increased intestinal mRNA levels of HMG-CoAR (59%), LDL receptor (LDLR) (52%), PCSK9 (187%), SREBP-2 (44%), and HNF-4alpha (13%). Atorvastatin 0-12 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 63-71 21123766-9 2011 These results indicate that HMG-CoAR inhibition with atorvastatin stimulates the intestinal expression of NPC1L1, LDLR, and PCSK9; increases cholesterol absorption; and reduces expression of ABCG5/8; these effects are most likely mediated by upregulation of the transcription factors SREBP-2 and HNF-4alpha. Atorvastatin 53-65 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 28-36
