Despite the tremendous improvement in cancer therapeutics, treatment of late-stage breast cancer remains a challenge for both basic scientists and clinicians. Lovastatin, a natural product derived from Aspergillus terreus or Monascus ruber, has been widely used as cholesterol-lowing drug in the clinic. It also has anti-cancer properties through poorly defined molecular mechanisms. In the presen...

Neurofibromatosis Type 1 (NF1) is a common neurological disorder caused by mutations in the gene encoding Neurofibromin, a p21Ras GTPase Activating Protein (GAP). Importantly, NF1 causes learning disabilities and attention deficits. A previous study showed that the learning and memory deficits of a mouse model of NF1 (nf1+/-) appear to be caused by excessive p21Ras activity leading to impairmen...

Background HMG CoA reductase inhibitors (or statins), a new class of lipid-lowering compounds, have raised expectations for more widespread use than that of the older lipidlowering drugs. Not only are they more effective in lowering LDL cholesterol, but they are better tolerated as well. No data exist concerning the effect of statins on early carotid atherosclerosis and clinical events in men a...

BACKGROUND In a recent study, we demonstrated the ability of lovastatin, a potent inhibitor of mevalonate synthesis, to inhibit the function of the epidermal growth factor receptor (EGFR). Lovastatin attenuated ligand-induced receptor activation and downstream signaling through the PI3K/AKT pathway. Combining lovastatin with gefitinib, a potent EGFR inhibitor, induced synergistic cytotoxicity i...

Background. Lovastatin produces consistent dose-related reductions in plasma levels of low density lipoprotein (LDL) cholesterol along with variable decreases in triglycerides and increases in high density lipoprotein (HDL) cholesterol. Patient characteristics from the Expanded Clinical Evaluation of Lovastatin (EXCEL) study were examined to determine their association with the magnitude of lov...

UNLABELLED The effects of lovastatin therapy on the parameters of body cholesterol metabolism were explored in nine hypercholesterolemic patients. Long-term cholesterol turnover studies were performed before therapy, and were repeated after 15 mo of lovastatin therapy (40 mg/d) while continuing on therapy. The major question addressed was whether a reduction in plasma cholesterol level with lov...

Recent studies have demonstrated that inhibition of mevalonate synthesis in cultured cells leads to altered cell morphology due to inhibition of protein prenylation. To investigate the effects in vivo of mevalonate deprivation in nondividing, terminally differentiated neural cells, we have analyzed the effects on retinal tissue of intravitreal injection of lovastatin, a potent inhibitor of the ...

Statins may act on inflammatory responses, decreasing oxidative stress and also reducing brain inflammation in several brain disorders. Epileptogenesis is a process in which a healthy brain becomes abnormal and predisposed to generating spontaneous seizures. We previously reported that lovastatin could prevent neuroinflammation in pilocarpine-induced status epilepticus (SE). In this context, th...

OBJECTIVE To (a) determine if converting patients on simvastatin to lovastatin affects whether they meet their low-density lipoprotein cholesterol (LDL-C) goals as defined by the National Cholesterol Education Program Adult Treatment Panel III (ATP III) clinical practice guidelines and (b) assess the change in health care expenditures associated with such a conversion. METHODS Primary and sec...

This study was performed to design bilayer floating tablets of simvastatin and lovastatin to give sustained release of simvastatin and immediate release of lovastatin. Bilayer floating tablets comprised of two layers i.e, immediate and sustained release layers. Bilayer floating tablets of simvastatin and lovastatin was formulated by using HPMCK 100M and super disintegrants like sodium alginate,...
