Atorvastatin induces downregulation of matrix metalloproteinase-2/9 in MDA-MB-231 triple negative breast cancer cells. MEDICAL ONCOLOGY (NORTHWOOD, LONDON, ENGLAND) 2022; 40:22. [PMID: 36445561 DOI: 10.1007/s12032-022-01880-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Accepted: 10/29/2022] [Indexed: 11/30/2022]
Abstract
Matrix metalloproteinases (MMPs) are a family of endopeptidases, mainly responsible of extracellular tissue remodeling. Abundant expression of MMPs leads to a number of tumorigenic processes including proliferation, angiogenesis, metastasis and invasion. Therefore, suppressing MMP expression is particularly important in cancer. Atorvastatin is a member of statin family, with cholesterol-lowering properties. Recently, it has emerged as a potential anticancer agent. Multiple researchers have reported promising results of atorvastatin use in cancer therapies. However, its effect on the expression of matrix metalloproteinases in breast cancer is unknown. In the present study, we have confirmed the apoptotic activity of atorvastatin on highly metastatic MDA-MB-231 triple negative breast cancer cells and investigated the gene expression of MMP-2/9. In this regard, MTT analysis was performed to evaluate cytotoxicity. Apoptotic activity was assessed by Annexin V binding and multicaspase assays. Western blot analysis was used to detect the apoptosis-related proteins. RT-PCR analysis was performed to evaluate the mRNA expression levels of MMP-2/9. Results indicated that atorvastatin reduces cell viability significantly at 5 µM after 48 h of treatment (p < 0.0001). It also induces caspase-dependent apoptosis, alters the expression of Bax and Bcl-2 in favour of apoptosis and stimulates cell cycle arrest at S phase (p < 0.05). Moreover, atorvastatin downregulates the mRNA expression of MMP-2 and MMP-9 significantly (p < 0.05). In conclusion, these results demonstrate for the first time that atorvastatin inhibits MMP-2 and MMP-9 gene expression in MDA-MB-231 cells, in addition to inducing caspase-dependent apoptosis.

Cancer-Associated Fibroblasts: The Origin, Biological Characteristics and Role in Cancer-A Glance on Colorectal Cancer. Cancers (Basel) 2022; 14:cancers14184394.

Abstract
Simple Summary Tumor microenvironment is a major contributor to tumor growth, metastasis and resistance to therapy. It consists of many cancer-associated fibroblasts (CAFs), which derive from different types of cells. CAFs detected in different tumor types are linked to poor prognosis, as in the case of colorectal cancer. Although their functions differ according to their subtype, their detection is not easy, and there are no established markers for such detection. They are possible targets for therapeutic treatment. Many trials are ongoing for their use as a prognostic factor and as a treatment target. More research remains to be carried out to establish their role in prognosis and treatment. Abstract The therapeutic approaches to cancer remain a considerable target for all scientists around the world. Although new cancer treatments are an everyday phenomenon, cancer still remains one of the leading mortality causes. Colorectal cancer (CRC) remains in this category, although patients with CRC may have better survival compared with other malignancies. Not only the tumor but also its environment, what we call the tumor microenvironment (TME), seem to contribute to cancer progression and resistance to therapy. TME consists of different molecules and cells. Cancer-associated fibroblasts are a major component. They arise from normal fibroblasts and other normal cells through various pathways. Their role seems to contribute to cancer promotion, participating in tumorigenesis, proliferation, growth, invasion, metastasis and resistance to treatment. Different markers, such as a-SMA, FAP, PDGFR-β, periostin, have been used for the detection of cancer-associated fibroblasts (CAFs). Their detection is important for two main reasons; research has shown that their existence is correlated with prognosis, and they are already under evaluation as a possible target for treatment. However, extensive research is warranted.

Abstract
OBJECTIVE To explore the effect of atorvastatin (AVT) on biological behaviors and the miR-146a/PI3K/Akt signaling pathway in human glioma cells. METHODS Human glioma U251 cells were treated with 8.0 μmol/L AVT or transfected with a miR-146a inhibitor or a negative control fragment (miR-146a NC) prior to AVT treatment. RT-PCR was used to detect miR-146a expression in the cells, and the changes in cell proliferation rate, apoptosis, cell invasion and migration were detected using MTT assay, flow cytometry, and Transwell assay. Western blotting was performed to detect the changes in cellular expressions of proteins in the PI3K/Akt signaling pathway. RESULTS AVT treatment for 48 h resulted in significantly increased miR-146a expression and cell apoptosis (P < 0.01) and obviously lowered the cell proliferation rate, invasion index, migration index, and expressions of p-PI3K and p-Akt protein in U251 cells (P < 0.01). Compared with AVT treatment alone, transfection with miR-146a inhibitor prior to AVT treatment significantly reduced miR-146a expression and cell apoptosis (P < 0.01), increased the cell proliferation rate, promoted cell invasion and migration, and enhanced the expressions of p-PI3K and p-Akt proteins in the cells (P < 0.01); these effects were not observed following transfection with miR-146a NC group (P>0.05). CONCLUSION AVT can inhibit the proliferation, invasion and migration and promote apoptosis of human glioma cells possibly by up-regulating miR-146a expression and inhibiting the PI3K/Akt signaling pathway.

Statins and Gliomas: A Systematic Review of the Preclinical Studies and Meta-Analysis of the Clinical Literature. Drugs 2022; 82:293-310.

Abstract
BACKGROUND Gliomas represent most common primary brain tumors. Glioblastoma (GBM) is the most common subtype and carries a poor prognosis. There is growing interest in the anti-glioma properties of statins. The aim of this study was to conduct a systematic review of the preclinical literature and to meta-analyze existing clinical studies to determine what benefit, if any, statins may confer in the context of glioma. METHODS The PubMed, Embase, Cochrane, and Web of Science libraries were queried in May 2021. Preclinical studies were included if they investigated the anti-cancer effects of statins in glioma in vitro and in vivo. Clinical studies were included if they reported incidence rates of glioma by statin use, or mortality outcomes among GBM patients by statin use. Pooled point estimates were calculated using a random-effects model. RESULTS In total, 64 publications, 51 preclinical and 13 clinical, were included. Preclinical studies indicated that statins inhibited glioma cell proliferation, migration, and invasion. These effects were time- and concentration-dependent. Synergistic anti-glioma effects were observed when statins were combined with other anti-cancer therapies. Clinical observational studies showed an inverse, albeit non-statistically significant, association between statin use and incidence rate of glioma (HR = 0.84, 95% CI 0.62-1.13, I2 = 72%, p-heterogeneity = 0.003, 6 studies). Statin use was not associated with better overall survival following GBM surgery (HR = 1.05, 95% CI 0.85-1.30, I2 = 30%, p-heterogeneity = 0.23, 4 studies). CONCLUSION Statins were potent anti-cancer drugs that suppressed glioma growth through various mechanisms in vitro; these effects have translated into the clinical realm, clinically but not statistically, in terms of glioma incidence but not GBM survival.

Abstract
BACKGROUND Erectile dysfunction (ED) is an evolving health problem in the aging male population. Chronic low-grade inflammation is a critical component of ED pathogenesis and a probable intermediate stage of endothelial dysfunction, especially in metabolic diseases, with the inclusion of obesity, metabolic syndrome, and diabetes. OBJECTIVE This review will present an overview of preclinical and clinical data regarding common inflammatory mechanisms involved in the pathogenesis of ED associated with metabolic diseases and the effect of antiinflammatory drugs on ED. METHODS A literature search of existing pre-clinical and clinical studies was performed on databases [Pubmed (MEDLINE), Scopus, and Embase] from January 2000 to October 2019. RESULTS Low-grade inflammation is a possible pathological role in endothelial dysfunction as a consequence of ED and other related metabolic diseases. Increased inflammation and endothelial/prothrombotic markers can be associated with the presence and degree of ED. Pharmacological therapy and modification of lifestyle and risk factors may have a significant role in the recovery of erectile response through reduction of inflammatory marker levels. CONCLUSION Inflammation is the least common denominator in the pathology of ED and metabolic disorders. The inflammatory process of ED includes a shift in the complex interactions of cytokines, chemokines, and adhesion molecules. These data have established that anti-inflammatory agents could be used as a therapeutic opportunity in the prevention and treatment of ED. Further research on inflammation-related mechanisms underlying ED and the effect of therapeutic strategies aimed at reducing inflammation is required for a better understanding of the pathogenesis and successful management of ED.

Abstract
Spheroid culture provides cells with a three-dimensional environment that can better mimic physiological conditions compared to monolayer culture. Technologies involved in the generation of cell spheroids are continuously being innovated to produce spheroids with enhanced properties. In this paper, we review the manufacturing capabilities of current cell spheroid generation technologies. We propose that spheroid generation technologies should enable tight and robust process controls to produce spheroids of consistent and repeatable quality. Future technology development for the generation of cell spheroids should look into improvement in process control, standardization, scalability and monitoring, in addition to advanced methods of spheroid transfer and characterization.

Abstract
PURPOSE Chronic inflammation increases the risks for cardiovascular disease, type 2 diabetes, and cancer. Recently, the antiinflammatory effects of statins, as cholesterol-lowering medications, have been considered. This study systematically reviewed and summarized earlier findings from randomized clinical trials about the effects of statins on serum concentrations of C-reactive protein (CRP) and interleukin (IL)-6 in patients with abnormal glucose homeostasis. METHODS Relevant articles published through October 2019 were searched using suitable key words on the PubMed/MEDLINE, SCOPUS, EMBASE, and Google Scholar databases. RCTs were included if they compared the effects of statins on serum concentrations of CRP and IL-6 in adults with abnormal glucose homeostasis. The effect sizes were represented as weighted mean differences (WMDs) and 95% CI s using a random-effects model. Subgroup analysis was performed to find possible sources of heterogeneity. FINDINGS Overall, 17 publications with 21 effect sizes and which enrolled 3766 subjects (1895 participants in intervention and 1871 in control groups) were included. Combining 13 effect sizes from 10 studies, a significant reduction in serum CRP concentration following the administration of atorvastatin was found (WMD, -0.35; 95% CI, -0.54 to -0.17; I2 = 90.6%). Based on 5 effect sizes from 4 studies, we found a statistically significant reduction in serum IL-6 concentration after atorvastatin therapy (WMD, -0.44; 95% CI, -0.65 to -0.22; I2 = 93.9%). Pooling 6 effect sizes from 5 studies revealed a significantly reduced serum concentration of CRP after simvastatin therapy (WMD, -0.66; 95% CI, -0.79 to -0.54; I2 = 97.6%). IMPLICATIONS The administration of atorvastatin or simvastatin in patients with abnormal glucose hemostasis was associated with a reduced serum CRP concentration. Atorvastatin therapy might also help to decrease serum IL-6 concentration in these patients.

Abstract
BACKGROUND No earlier study summarized findings on the effect of statins on inflammatory biomarkers in apparently healthy individuals or those with chronic diseases. This study was done to systematically review earlier publications on the effect of statins on serum concentrations of C-reactive protein (CRP) and Interleukin-6 (IL-6) in apparently healthy individuals or those with chronic diseases. METHODS We searched relevant publications published up to December 2018 in PubMed, MEDLINE, SCOPUS, EMBASE, and Google Scholar databases. For this purpose, suitable MESH and non-MESH keywords were used. Randomized placebo-controlled clinical trials that examined the effect of statins on serum concentrations of CRP and IL-6 in apparently healthy adults or those with chronic diseases were included. RESULTS Overall, 18 studies with 23 effect sizes, that enrolled 32,156 individuals (38% female and 62% male; mean age: 44.79 years) were included. When we combined 21 effect sizes from 16 studies, we observed a significant reduction in circulating levels of CRP following administration of statins [Weighted Mean Difference (WMD): -0.80; 95% CI: -1.05, -0.56]. Combining 12 effect sizes from 11 studies, a significant reduction was found in serum CRP concentrations following administration of Atorvastatin (WMD: -0.57; 95% CI: -0.78, -0.35). Pooling 5 effect sizes from 2 studies, we found a significant reduction in serum concentrations of CRP following administration of Simvastatin (WMD: -0.29; 95% CI: -0.49, -0.10; I2 = 88.5%). Combining 6 effect sizes from 5 studies, we found a significant reduction in serum IL-6 concentrations after Atorvastatin therapy (WMD: -2.13; 95% CI: -3.96, -0.30; I2 = 98.6%). CONCLUSIONS In conclusion, we found that statins administration in apparently healthy people or those with chronic diseases help reducing serum CRP concentrations. In addition, Atorvastatin administration resulted in reduced serum IL-6 concentrations in these people.

Secukinumab attenuates reactive astrogliosis via IL-17RA/(C/EBPβ)/SIRT1 pathway in a rat model of germinal matrix hemorrhage. CNS Neurosci Ther 2019; 25:1151-1161. [PMID: 31020769 PMCID: PMC6776744 DOI: 10.1111/cns.13144] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 04/08/2019] [Accepted: 04/09/2019] [Indexed: 12/28/2022] Open
Abstract
Aims Reactive astrogliosis plays a critical role in neurological deficits after germinal matrix hemorrhage (GMH). It has been reported that interleukin‐17A and IL‐17A receptor IL‐17RA/(C/EBPβ)/SIRT1 signaling pathway enhances reactive astrogliosis after brain injuries. We evaluated the effects of secukinumab on reactive astrogliosis in a rat pup model of GMH. Methods A total of 146 Sprague Dawley P7 rat pups were used. GMH was induced by intraparenchymal injection of collagenase. Secukinumab was administered intranasally 1 hour post‐GMH. C/EBPβ CRISPR or SIRT1 antagonist EX527 was administrated intracerebroventricularly (icv) 48 hours and 1 hour before GMH induction, respectively. Neurobehavior, Western blot, histology, and immunohistochemistry were used to assess treatment regiments in the short term and long term. Results The endogenous IL‐17A, IL‐17RA, C/EBPβ, and GFAP and proliferation marker CyclinD1 were increased, while SIRT1 expression was decreased after GMH. Secukinumab treatment improved neurological deficits, reduced ventriculomegaly, and increased cortical thickness. Additionally, treatment increased SIRT1 expression and lowered proliferation proteins PCNA and CyclinD1 as well as GFAP expression. C/EBPβ CRISPR activation plasmid and EX527 reversed the antireactive astrogliosis effects of secukinumab. Conclusion Secukinumab attenuated reactive astrogliosis and reduced neurological deficits after GMH, partly by regulating IL‐17RA/(C/EBPβ)/SIRT1 pathways. Secukinumab may provide a promising therapeutic strategy for GMH patients.

Abstract
Epithelial cancer grows in vivo in a microenvironment that comprises tumour, stroma, and immune cells. A three-dimensional (3D) culture model might be able to mimic the tumour microenvironment in vivo; therefore, we developed a new 3D epithelial cancer model using in vitro cell-sheet engineering and compared the results of treatment with several chemotherapeutic drugs among the 3D cell-sheet model, spheroid culture, and 2D cell culture. Methods: The cell sheet comprised keratinocytes and a plasma fibrin matrix containing fibroblasts. Cancer spheroids with or without cancer-associated fibroblasts (CAFs) were interposed between the keratinocytes and fibrin layer. Cell growth, viability, and hypoxia were measured using the cell counting kit-8, LIVE/DEAD assay, and propidium iodide and LOX-1 staining. The morphology, invasion, and mRNA and protein expression were compared among the different cell culture models. Results: Enhanced resistance to sorafenib and cisplatin by cancer spheroids and CAFs was more easily observed in the 3D than in the 2D model. Invasion by cancer-CAF spheroids into the fibrin matrix was more clearly observed in the 3D cell sheet. The expansion of viable cancer cells increased in the 3D cell sheet, particularly in those with CAFs, which were significantly inhibited by treatment with 10 μM sorafenib or 20 μM cisplatin (P < 0.05). TGF-β1, N-cadherin, and vimentin mRNA and protein levels were higher in the 3D cell-sheet model. Conclusions: The 3D cell sheet-based cancer model could be applied to in vitro observation of epithelial cancer growth and invasion and to anticancer drug testing.
