We investigated the effects of fluvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, on endothelial vasoactive substances using human umbilical vein endothelial cells (HUVECs). Incubation of HUVECs with fluvastatin for 12 h increased endothelial nitric oxide synthase (eNOS) mRNA expression in a concentration-dependent manner (peak, 276 +/- 38%, mean +/- S.D., of the control, at 1.0 microM fluvastatin, P<0.01). In addition, fluvastatin increased eNOS protein production (245 +/- 51% of the control level, P<0.05) as well as nitrite production (165 +/- 35% of the control level, P<0.01). In contrast, incubation of HUVECs with 1.0 microM fluvastatin for 12 h significantly reduced the production of endothelin-1 (ET-1) and preproET-1 mRNA expression in HUVECs (28 +/- 1% and 39 +/- 1% of the control level, respectively, P<0.01). Our results suggest that fluvastatin might be involved in improvement of endothelial function and prevention of the progression of atherosclerosis.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
