The anti ‑dengue virus properties of statins may be associated with alterations in the cellular antiviral profile expression.
The anti‑dengue virus properties of statins may be associated with alterations in the cellular antiviral profile expression. Mol Med Rep. 2016 Jul 13; Authors: Bryan-Marrugo OL, Arellanos-Soto D, Rojas-Martinez A, Barrera-Saldaña H, Ramos-Jimenez J, Vidaltamayo R, Rivas-Estilla AM Abstract Dengue virus (DENV) susceptibility to cholesterol depleting treatments has been previously reported. There are numerous questions regarding how DENV seizes cellular machinery and cholesterol to improve viral production and the effect of cholesterol sequestering agents on the cellular antiviral response. The aim of...

Id: 126: role of syndecan-1 in mechanical stress-induced lung endothelial cell inflammatory responses mediated by integrin beta4
Conclusion Our results implicate syndecan-1 as an important mediator of EC ITGB4 tyrosine phosphorylation affected by both simvastatin and mechanical-stress. These findings represent a novel area of investigation that may ultimately yield new therapeutic targets and strategies for patients with ventilator-induced lung injury, a form of ALI precipitated by excessive lung stretch.

Lovastatin lactone elicits human lung cancer cell apoptosis via a COX-2/PPARγ-dependent pathway.
This study investigates the mechanism underlying human lung cancer cell death by lovastatin and the role of the prostaglandin (PG)-synthesizing enzyme cyclooxygenase-2 (COX-2) in this process. In A549 and H358 lung carcinoma cells the lipophilic prodrug lovastatin lactone led to a concentration-dependent decrease of viability and induction of DNA fragmentation, whereas its HMG-CoA-inhibitory, ring-open acid form was inactive in this respect. Apoptotic cell death by lovastatin was accompanied by high intracellular levels of the lactone form, by upregulation of COX-2 mRNA and protein, as well as by increased formation of per...

Statins up-regulate SmgGDS through {beta}1-integrin/Akt1 pathway in endothelial cells
Conclusion These results indicate that statins selectively up-regulate SmgGDS in endothelial cells, for which the β1-integrin/Akt1 pathway may be involved, demonstrating the novel aspects of the pleiotropic effects of statins.

Atorvastatin restricts HIV replication in CD4+ T cells by upregulation of p21
Conclusion: The results demonstrate a novel mechanism by which atorvastatin induced resistance of CD4+ T cells to HIV-1 infection via p21 upregulation and suggest that statins may hold particular promise for some HIV-infected individuals.

Involvement of Pregnane X Receptor in the Impaired Glucose Utilization Induced by Atorvastatin in Hepatocytes.
In conclusion, atorvastatin impaired glucose utilization in hepatocytes via repressing GLUT2 and GCK expressions, which may be partly due to PXR activation. PMID: 26616219 [PubMed - as supplied by publisher]

Cerivastatin Represses Atherogenic Gene Expression Through the Induction of KLF2 via Isoprenoid Metabolic Pathways.
Abstract Earlier clinical studies have reported that cerivastatin has an antiatherosclerotic effect that is unique among the statins. In our study, human THP-1 macrophage cells were used to study the effects of various statins on the expressions of the atherosclerotic genes and Kruppel-like factor 2 (KLF2). Cerivastatin significantly inhibited the two atherosclerotic genes, monocyte chemoattractant protein-1 (MCP-1) and C-C chemokine receptor type 2 (CCR2) at both the mRNA and protein levels, while the other statins did not. Accordingly, cerivastatin was also the most potent inducer of KLF2 transcription in the ma...

Inhibition of autophagy potentiates pemetrexed and simvastatin-induced apoptotic cell death in malignant mesothelioma and non-small cell lung cancer cells
In this study, we determined whether autophagy could be induced by pemetrexed and simvastatin cotreatment in malignant mesothelioma and NSCLC cells. Furthermore, we determined whether inhibition of autophagy drives apoptosis in malignant mesothelioma and NSCLC cells. Malignant mesothelioma MSTO-211H and A549 NSCLC cells were treated with pemetrexed and simvastatin alone and in combination to evaluate their effect on autophagy and apoptosis. Cotreatment with pemetrexed and simvastatin induced greater caspase-dependent apoptosis and autophagy than either drug alone in malignant mesothelioma and NSCLC cells. 3-Methyladenine (...

Estrogen receptor mediates simvastatin-stimulated osteogenic effects in bone marrow mesenchymal stem cells.
In this study, we hypothesize that the estrogen receptor (ER) mediates simvastatin-induced osteogenic differentiation. ER antagonists and siRNA were used to determine the involvement of the ER in simvastatin-induced osteogenesis in mouse bone marrow mesenchymal stem cells (D1 cells). Osteogenesis was evaluated by mRNA expression, protein level/activity of osteogenic markers, and mineralization. The estrogen response element (ERE) promoter activity and the ER-simvastatin binding affinity were examined. Our results showed that the simvastatin-induced osteogenic effects were decreased by treatment with ERα antagonists and ER...

Simvastatin protects Sertoli cells against cisplatin cytotoxicity through enhanced gap junction intercellular communication.
Authors: Wang L, Peng J, Huang H, Wang Q, Yu M, Tao L Abstract Cisplatin, an important chemotherapeutic agent against testicular germ cell cancer, induces testicular toxicity on Leydig and Sertoli cells, leading to serious side-effects such as azoospermia and infertility. In a previous study, it was found that simvastatin enhanced the sensitivity of Leydig tumor cells to chemotherapeutic toxicity through the enhancement of gap junction functions. In the present study, the effect of simvastatin on the sensitivity of normal Sertoli cells to cisplatin and the role of gap junctions in such effects was investigated. T...

Abstract 16: Combination simvastatin and metformin induces G1-phase cell cycle arrest and Ripk1- and Ripk3-dependent necroptosis in C4-2B osseous metastatic castration-resistant prostate cancer cells
Castration-resistant prostate cancer (CRPC) cells acquire resistance to chemotherapy and apoptosis in part due to enhanced aerobic glycolysis and biomass production, known as Warburg effect. We previously demonstrated that combination simvastatin (SIM) and metformin (MET) ameliorates critical Warburg effect-related metabolic aberrations of C4-2B cells, synergistically and significantly decreases CRPC cell viability and metastatic properties, with minimal effect on normal prostate epithelial cells, and inhibits primary prostate tumor growth, metastasis, and biochemical failure in an orthotopic model of metastatic CRPC, more...

New CETP inhibitor K-312 reduces PCSK9 expression: a potential effect on LDL cholesterol metabolism
Despite significant reduction of cardiovascular events by statin treatment, substantial residual risk persists, driving emerging needs for the development of new therapies. We identified a novel cholesteryl ester transfer protein (CETP) inhibitor, K-312, that raises HDL and lowers LDL cholesterol levels in animals. K-312 also suppresses hepatocyte expression of proprotein convertase subtilisin/kexin 9 (PCSK9), a molecule that increases LDL cholesterol. We explored the underlying mechanism for the reduction of PCSK9 expression by K-312. K-312 inhibited in vitro human plasma CETP activity (IC50; 0.06 μM). Administration o...
