To evaluate the onset timing of musculoskeletal adverse events (MAEs) that develop during statin monotherapy and to determine whether concomitant drugs used concurrently with statin therapy shifts the onset timing of MAEs. Cases in which statins (atorvastatin, rosuvastatin, simvastatin, lovastatin, fluvastatin, pitavastatin, and pravastatin) were prescribed were extracted from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) Data Files. The onset timing of MAEs during statin monotherapy was evaluated by determining the difference between statin start date and MAE onset date...

The nucleolus is a dynamic structure that has roles in various physiological and pathophysiological processes. Perturbations on many aspects of the nucleolar functions are thought to cause "nucleolar stress", which occurs in response to a variety of chemotherapeutic drugs. The main characteristic changes of nucleolar stress include: 1) reduction of the size and volume of the nucleolus; 2) inhibition of RNA Pol I-mediated rRNA synthesis; and 3) nucleoplasmic translocation of nucleolar stress-related proteins...

For many secondary metabolites, heterologous synthesis is the definitive step to determine their required biosynthetic genes. Using a multivector expression system in Saccharomyces cerevisiae, we reconstituted not only two natural statins from two fungal species, i.e., lovastatin from Aspergillus terreus and FR901512 from Xylaria grammica, but also new statin structures by mixing their genes. Combinatorial gene exchange experiments revealed the functional promiscuity of two polyketide synthases in A. terreus, lovB, and lovF; they could synthesize FR901512 with Xylaria genes...

More than half of the activity secondary metabolites from microorganisms are produced by filamentous fungi. The metabolites that are well known include penicillin, cyclosporine A, lovastatin, and so on. Due to their importance in agriculture, medicine and industry, biosynthesis and regulation of these fungal secondary metabolites have attracted much attention. The biosynthesis of fungal secondary metabolites is a complex process which generally includes multistep enzymatic reactions. Commonly, the process is controlled by elaborate regulations at different levels...

Increasing evidence supports a close relationship between Ras-ERK1/2 activation in the striatum and L-DOPA-induced dyskinesia (LID). ERK1/2 activation by L-DOPA takes place through the crosstalk between D1R/AC/PKA/DARPP-32 pathway and NMDA/Ras pathway. Compelling genetic and pharmacological evidence indicates that Ras-ERK1/2 inhibition prevents LID onset and may even revert already established dyskinetic symptoms. However, it is currently unclear whether exacerbation of Ras-ERK1/2 activity in the striatum may further aggravate dyskinesia in experimental animal models...

Axillary bud activation and outgrowth were dependent on local cytokinin, and that bud activation preceded the activation of cell cycle and cell growth genes in apple branching. Cytokinin is often applied to apple trees to produce more shoot branches in apple seedlings. The molecular response of apple to the application of cytokinin, and the relationship between bud activation and cell cycle in apple branching, however, are poorly understood. In this study, RNA sequencing was used to characterize differential expression genes in axillary buds of 1-year grafted "Fuji" apple at 4 and 96 h after cytokinin application...

Metabolic rewiring is an integral part of tumor growth. Among metabolic pathways, the Mevalonic-Acid-Pathway (MVAP) plays a key role in maintaining membrane architecture through cholesterol synthesis, thereby affecting invasiveness. In the current study, we show for the first time that CD133Hi pancreatic tumor initiating cells (TIC) have increased expression of MVAP enzymes, cholesterol-content and Caveolin expression. Further, we show that CD133 in these cells is localized in the lipid-rafts (characterized by Cav-1-cholesterol association)...

INTRODUCTION: Aggregation of amyloid-β (Aβ) peptides represents a crucial step in the pathogenesis of Alzheimer disease (AD). Compelling evidence from preclinical studies has established that statins may reduce amyloidogenesis and Aβ-mediated neurodegeneration, supporting a potential role of statin treatment in the prevention of AD. Different statins have been shown to interfere indirectly with Aβ production and clearance through either cholesterol-dependent or cholesterol-independent mechanisms...

Since the first approval of lovastatin in 1987, hydroxy-methyl-glutaryl CoA (HMG CoA) reductase inhibitors, or statins, have been effective and widely popular cholesterol-lowering agents with substantial benefits for the prevention and treatment of cardiovascular disease. Not all patients can tolerate these drugs, however, and statin intolerance is most frequently associated with a range of side effects directed toward skeletal muscle, termed statin-associated muscle symptoms or SAMS. SAMS are particularly difficult to treat because there are no validated biomarkers or tests that can be used to confirm patient self-reports of SAMS, and a number of patients who report SAMS have non-specific muscle pain not attributable to statin therapy...

Interleukin (IL)-33 is a member of the IL-1 family and is able to act cardioprotective. The aim of this study was to investigate the regulation of IL-33 by 3-hydroxy-3-methylglutaryl-coenzyme-A (HMG-CoA) reductase inhibitors (statins) and bisphosphonates (BPs) in human cardiac tissue. The lipophilic fluvastatin, simvastatin, atorvastatin, and lovastatin as well as the nitrogenous BPs alendronate and ibandronate, but not hydrophilic pravastatin increased IL-33 mRNA and intracellular IL-33 protein levels in both human adult cardiac myocytes (HACM) and fibroblasts (HACF)...

Papillary thyroid carcinoma (PTC) is the fastest-growing disease caused by numerous molecular alterations in addition to previously reported DNA mutations. There is a compelling need to identify novel transcriptomic alterations that are associated with the pathogenesis of PTC with potential diagnostic and prognostic implications. Methods: We gathered and compared 242 expression profiles between paired PTC and adjacent normal tissues and identified and validated the coding and long non-coding RNAs (lncRNAs) associated with the extrathyroidal extension (ETE) of 655 PTC patients in two independent cohorts, followed by predicting their interactions with drugs...

Simvastatin is a semisynthetic cholesterol-lowering medication and one of the top-selling statins in the world. Currently, industrial production of simvastatin acid (SVA) is a multistep process starting from the natural product lovastatin. For this reason, there is significant interest in direct production of simvastatin from a microbial host. In this study, six heterologous biosynthetic genes were introduced into Saccharomyces cerevisiae and the acyl-donor dimethylbutyryl-S-methyl mercaptopropionate (DMB-SMMP) was added, resulting in initial production of 0...

Resistance to therapies, recurrence, and metastasis remain challenging issues for breast cancer patients, particularly for triple-negative and breast cancer stem cells. The activation of the epithelial-to-mesenchymal transition (EMT) plays an indispensable role in the poor prognosis of those types. The accumulating proofs indicated that the mevalonate pathway crucially mediates a poor prognosis. Here, the effects of lipophilic 3-hydroxy-3-methyl-glutaryl-coenzyme A inhibitors, atorvastatin, lovastatin, and simvastatin, were investigated on expression and function of a selected profile of EMT-related genes in breast cancer stem-like cells...
