||Lovastatin is an inhibitor of HMG-CoA reductase with IC50 of 3.4 nM in a cell-free assay, has a direct cellular effect independent of a cholesterol-lowering effect and delays the onset and progression of diabetic nephropathy. It has a potential application to treat PD via antioxidant effect, and it promotes fibrosis and epithelial to mesenchymal transition, by regulating the production of CCN2 in human gingival fibroblasts.|

|Lovastatin suppresses the aberrant tau phosphorylation from FTDP-17 mutation and okadaic acid-induction in rat primary neurons.[Pubmed: 25770969]|
|Statins are a class of cholesterol-lowering drugs and have been suggested therapeutic use for neurodegenerative diseases including Alzheimer's disease (AD). Our recent studies revealed a neuronal protective effect of Lovastatin (LOV) from N-methyl-d-aspartic acid (NMDA) excitotoxicity. The neuroprotective mechanism of statins, however, is far unknown. |
METHODS AND RESULTS:
Here we demonstrated that LOV suppressed the aberrant tau phosphorylation both from frontotemporal dementia and Parkinsonism linked to chromosome 17 (FTDP-17) mutation and okadaic acid (OA) induction in cultured rat primary neurons. The protective effect of LOV occurred at multiple pathological sites of tau protein, including Tyr181, Tyr231 Ser202/Tyr205, Tyr212/Ser214 and Ser396/Ser404. Further analysis revealed that the potential mechanism of the suppressive effect of LOV resulted from two aspects, activating OA-inhibited protein phosphatase 2A (PP2A) activity and attenuating OA-induced activity of tau kinases CDK5/P25 and CDK2/4, but not glycogen synthase kinase 3β (GSK3β).
These findings give new insights into the molecular mechanism of LOV-mediated neuroprotective effect and provide experimental evidence for its therapeutic use in AD.

|Prevention of Phenytoin-Induced Gingival Overgrowth by Lovastatin in Mice.[Pubmed: 25843680]|
|Drug-induced gingival overgrowth is caused by the antiseizure medication phenytoin, calcium channel blockers, and ciclosporin. Characteristics of these drug-induced gingival overgrowth lesions differ.
METHODS AND RESULTS:
We evaluate the ability of a mouse model to mimic human phenytoin-induced gingival overgrowth and assess the ability of a drug to prevent its development. Lovastatin was chosen based on previous analyses of tissue-specific regulation of CCN2 production in human gingival fibroblasts and the known roles of CCN2 in promoting fibrosis and epithelial to mesenchymal transition. Data indicate that anterior gingival tissue overgrowth occurred in phenytoin-treated mice based on gross tissue observations and histomorphometry of tissue sections. Molecular markers of epithelial plasticity and fibrosis were regulated by phenytoin in gingival epithelial tissues and in connective tissues similar to that seen in humans. Lovastatin attenuated epithelial gingival tissue growth in phenytoin-treated mice and altered the expressions of markers for epithelial to mesenchymal transition. Data indicate that phenytoin-induced gingival overgrowth in mice mimics molecular aspects of human gingival overgrowth and that Lovastatin normalizes the tissue morphology and the expression of the molecular markers studied. Data are consistent with characterization of phenytoin-induced human gingival overgrowth in vivo and in vitro characteristics of cultured human gingival epithelial and connective tissue cells.
Findings suggest that statins may serve to prevent or attenuate phenytoin-induced human gingival overgrowth, although specific human studies are required.

|Lovastatin inhibits transforming growth factor-beta1 expression in diabetic rat glomeruli and cultured rat mesangial cells.[Pubmed: 10616843]|
|Diabetic nephropathy is a leading cause of end-stage renal disease and is characterized by excessive deposition of extracellular matrix (ECM) proteins in the glomeruli. Transforming growth factor-beta (TGF-beta) is the major mediator of excessive accumulation of ECM proteins in diabetic nephropathy through upregulation of genes encoding ECM proteins as well as downregulation of genes for ECM-degrading enzymes. It has been shown that Lovastatin, an inhibitor of 3-hydroxy3-methylglutaryl CoA reductase, delays the onset and progression of different models of experimental nephropathy.
METHODS AND RESULTS:
To evaluate the effect of Lovastatin on the development and progression of diabetic nephropathy, streptozotocin-induced diabetic rats were studied for 12 mo. In untreated diabetic rats, there were significant increases in blood glucose, urine albumin excretion, kidney weight, glomerular volume, and TGF-beta1 mRNA expression in the glomeruli compared with normal control rats treated with citrate buffer only. Treatment with Lovastatin in diabetic rats significantly suppressed the increase in urine albumin excretion, kidney weight, glomerular volume, and TGF-beta1 mRNA expression despite high blood glucose levels. To elucidate the mechanisms of the renal effects of Lovastatin, rat mesangial cells were cultured under control (5.5 mM) or high (30 mM) glucose with Lovastatin alone, mevalonate alone, or with both. Under high glucose, TGF-beta1 and fibronectin mRNA and proteins were upregulated. These high glucose-induced changes were suppressed by Lovastatin (10 micro/M) and nearly completely restored by mevalonate (100 microM).
These results suggest that Lovastatin has a direct cellular effect independent of a cholesterol-lowering effect and delays the onset and progression of diabetic nephropathy, at least in part, through suppression of glomerular expression of TGF-beta1.

|The neuroprotective effect of lovastatin on MPP+-induced neurotoxicity is not mediated by PON2.[Pubmed: 25842176]|
|Parkinson's disease (PD) is a neurodegenerative disorder characterized by loss of the pigmented dopaminergic neurons in the substantia nigra pars compacta with subsequent striatal dopamine (DA) deficiency and increased lipid peroxidation. The etiology of the disease is still unclear and it is thought that PD may be caused by a combination of genetic and environmental factors.
In the search of new pharmacological options, statins have been recognized for their potential application to treat PD, due to their antioxidant effect.
METHODS AND RESULTS:
The aim of this work is to contribute in the characterization of the neuroprotective effect of Lovastatin in a model of PD induced by 1-methyl-4-phenylpyridinium (MPP(+)). Male Wistar rats (200-250 g) were randomly allocated into 4 groups and administered for 7 days with different pharmacological treatments. Lovastatin administration (5 mg/kg) diminished 40% of the apomorphine-induced circling behavior, prevented the striatal DA depletion and lipid peroxides formation by MPP(+) intrastriatal injection, as compared to the group of animals treated only with MPP(+). Lovastatin produced no change in paraoxonase-2 (PON2) activity.
It is evident that Lovastatin conferred neuroprotection against MPP(+)-induced protection but this effect was not associated with the induction of PON2 in the rat striatum.

|Lovastatin production: From molecular basis to industrial process optimization.[Pubmed: 25868803]|
|Lovastatin, composed of secondary metabolites produced by filamentous fungi, is the most frequently used drug for hypercholesterolemia treatment due to the fact that Lovastatin is a competitive inhibitor of HMG-CoA reductase. Moreover, recent studies have shown several important applications for Lovastatin including antimicrobial agents and treatments for cancers and bone diseases. Studies regarding the Lovastatin biosynthetic pathway have also demonstrated that Lovastatin is synthesized from two-chain reactions using acetate and malonyl-CoA as a substrate. It is also known that there are two key enzymes involved in the biosynthetic pathway called polyketide synthases (PKS). Those are characterized as multifunctional enzymes and are encoded by specific genes organized in clusters on the fungal genome. Since it is a secondary metabolite, cultivation process optimization for Lovastatin biosynthesis has included nitrogen limitation and non-fermentable carbon sources such as lactose and glycerol. Additionally, the influences of temperature, pH, agitation/aeration, and particle and inoculum size on Lovastatin production have been also described. Although many reviews have been published covering different aspects of Lovastatin production, this review brings, for the first time, complete information about the genetic basis for Lovastatin production, detection and quantification, strain screening and cultivation process optimization. Moreover, this review covers all the information available from patent databases covering each protected aspect during Lovastatin bio-production.|
