Abstract
Oxidative stress (OxS) is the cause and the consequence of metabolic syndrome (MetS), the incidence and economic burden of which is increasing each year. OxS triggers the dysregulation of signaling pathways associated with metabolism and epigenetics, including microRNAs, which are biomarkers of metabolic disorders. In this review, we aimed to summarize the current knowledge regarding the interplay between microRNAs and OxS in MetS and its components. We searched PubMed and Google Scholar to summarize the most relevant studies. Collected data suggested that different sources of OxS (e.g., hyperglycemia, insulin resistance (IR), hyperlipidemia, obesity, proinflammatory cytokines) change the expression of numerous microRNAs in organs involved in the regulation of glucose and lipid metabolism and endothelium. Dysregulated microRNAs either directly or indirectly affect the expression and/or activity of molecules of antioxidative signaling pathways (SIRT1, FOXOs, Keap1/Nrf2) along with effector enzymes (e.g., GPx-1, SOD1/2, HO-1), ROS producers (e.g., NOX4/5), as well as genes of numerous signaling pathways connected with inflammation, insulin sensitivity, and lipid metabolism, thus promoting the progression of metabolic imbalance. MicroRNAs appear to be important epigenetic modifiers in managing the delicate redox balance, mediating either pro- or antioxidant biological impacts. Summarizing, microRNAs may be promising therapeutic targets in ameliorating the repercussions of OxS in MetS.

Abstract
Non-alcoholic fatty liver disease is one of the main causes of chronic liver disease and therefore is currently considered a major public health problem. Sirtuin 1 (SIRT1) is an NAD-dependent deacetylase enzyme that contributes in the regulation of metabolic processes and protects against lipid accumulation in hepatocytes. Its expression is potentially regulated by microRNAs which attach to the 3' untranslated region (3'-UTR) of their target mRNA. HepG2 cells were incubated by glucose to induce lipid accumulation and were subsequently transfected with mir-23b mimic and inhibitor. Real-time PCR was used for measuring the expression of mir-23b and SIRT1 mRNA. Cell survival assay and intracellular triglyceride measurement were performed using colorimetric methods. Determination of SIRT1 protein level and activity were done by western blot and fluorometric analysis, respectively. The interaction of miR-23b with 3'-UTR of SIRT1 mRNA was confirmed by dual luciferase. miR-23b mimic inhibited gene and protein expression of SIRT1, while the inhibitor of miR-23b significantly elevated the expression levels of SIRT1 mRNA and protein. The results showed that the 3'-UTR of SIRT1 mRNA is a direct target for miR-23b. The intracellular triglyceride level was increased following the inhibition of SIRT1 in transfected HepG2 cell by miR-23b mimic. Cell viability was decreased in response to miR-23b upregulation compared to control cells. miR-23b reduces the expression and activity of SIRT1 and therefore may be a causative factor in the enhancement of lipid accumulation in HepG2 cells.

BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2017; 1865:186-195. [PMID: 28939056 DOI: 10.1016/j.bbamcr.2017.09.010] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2017] [Revised: 09/15/2017] [Accepted: 09/18/2017] [Indexed: 01/12/2023]
Abstract
Adipogenesis is a process of preadipocyte differentiation that requires action of numerous factors. Monocyte chemoattractant protein-1-induced protein 1 (MCPIP1) possesses the N-terminus of the PilT protein (PilT N-terminus or PIN domain) that has RNase properties. This protein degrades transcripts coding for inflammation and differentiation - related proteins. Moreover, MCPIP1 is a broad suppressor of the miRNA biogenesis. We previously found that MCPIP1 degrades transcript encoding CCAAT/Enhancer Binding Protein Beta (C/EBPβ) and influences adipogenesis. Subsequently, we aimed to determine adipocyte miRNA expression profile in differentiating mouse preadipocytes, 3T3-L1, by overexpressing MCPIP1. Using Next-Generation Sequencing (NSG) we showed that MCPIP1 overexpression results in modulated levels of 58 miRNAs in adipocytes on day 2 of differentiation. Among them, 30 miRNAs showed significantly reduced levels and 28 showed increased levels in comparison to control. Approximately one third of the modulated miRNAs were not previously reported to be involved in adipocytes differentiation. Our analysis revealed that 24 down-regulated and 23 up-regulated miRNAs (at least 1.5-fold) influence 19 signaling pathways that are important for adipogenesis. Furthermore, reduced miRNA levels result in the up-regulation of their targets. By using luciferase reporter assay, we demonstrated that miR-32-5p and miR-9-3p directly target the 3'UTR region of Mapk8 and Tiam1, respectively. In addition, activation of MAP kinases pathway (JNK and p38), proposed as being regulated by down-regulated miRNAs, was higher in WTMCPIP1 than in D141NMCPIP1 or control 3T3-L1 adipocytes. Our results indicate a considerable impact of MCPIP1 on miRNAs levels and its significance in adipogenesis.

Abstract
MicroRNAs are short, single-stranded non-coding RNA molecules that function as regulators of tumor progression in various cancers, including glioma. The present study sought to investigate the biological functions of miR-9-3p in glioma progression. The results of a microRNA microarray indicated that microRNA-9-3p (miR-9-3p, miR-9*) is down-regulated in high-grade (grades III and IV) gliomas compared with non-tumor tissues. These results were confirmed with real-time PCR. The miR-9-3p expression level was associated with age and tumor grade. Herpud1 was regulated by miR-9-3p in glioma cells and tissues and was identified as a miR-9-3p target with luciferase reporter assays. Glioma cells transfected with miR-9-3p mimics or HERPUD1-RNAi had more apoptotic cells than them in control after induced by H2O2. Our results indicated that low expression of miR-9-3p results in a high level of Herpud1, which may protect against apoptosis in glioma.
