  • Down-regulation of 14-3-3 zeta sensitizes human glioblastoma cells to
           apoptosis induction
    • Authors: Mansoureh Hashemi; Alireza Zali; Javad Hashemi; Saeed Oraee-Yazdani; Akhtar Akbari
      Pages: 616 - 625
      Abstract: Strong 14-3-3 zeta protein expression plays an important role in tumorigenesis, including in the maintenance of cell growth, resistance increase, and the prevention of apoptosis. In this study, we focus on two targets: (1) the expression of 14-3-3 zeta in the different grades of human astrocytoma (II–IV), (2) suppression of 14-3-3 zeta protein expression in glioblastoma derived astrocytes by 14-3-3 zeta shRNA lentiviral particles. The tissues of human astrocytoma were provided from 30 patients (ten of each grade of astrocytoma). Control tissues were obtained from the peritumoral brain zone of those patients with glioblastoma. The protein and mRNA expression levels of each astrocytoma grade were assessed via western blotting and RT-PCR, respectively. Results indicated that 14-3-3 zeta was significantly expressed in glioblastoma multiforme (grade IV) and 14-3-3 zeta expression levels enhanced according to the increase of astrocytoma malignancy. In the cellular study for knock down of the 14-3-3 zeta protein, surgical biopsy of glioblastoma was used to isolate primary astrocyte. Astrocytes were transduced with 14-3-3 zeta shRNA or non-targeted shRNA lentiviral particles. Furthermore, reduction of the 14-3-3 zeta protein expression in the astrocytes evaluated through qRT-PCR and western blot after transduction of 14-3-3 zeta shRNA lentiviral particles. Moreover, apoptosis properties, including DNA fragmentation and ratio increase of Bax/Bcl-2 were observed in astrocytes following reduction of 14-3-3 zeta protein expression. Further observation indicated that the mitochondrial pathway through release of cytochorome c and caspase-3 activity was involved in the apoptosis induction. Hence, this study demonstrates a key role of the 14-3-3 zeta protein in tumorigenesis but also indicates that 14-3-3 zeta can be considered as a target for the astrocytoma treatment specially glioblastoma.

  • A thiopyran derivative with low murine toxicity with therapeutic potential
           on lung cancer acting through a NF-κB mediated apoptosis-to-pyroptosis
    • Authors: Liping Chen; Bixia Weng; Huimin Li; Haonan Wang; Qian Li; Xiaoyan Wei; Hui Deng; Sicen Wang; Chengxi Jiang; Renyu Lin; Jianzhang Wu
      Abstract: Pyroptosis is a novel manner of cell death that can be mediated by chemotherapy drugs. The awareness of pyroptosis is significantly increasing in the fields of anti-tumor research and chemotherapy drugs. Invoking the occurrence of pyroptosis is an attractive prospect for the treatment of lung cancer. Here, the compound L61H10 was obtained as a thiopyran derivative to compare its activity with curcumin. It was indicated that L61H10 exhibited good anti-tumor activity both in vitro and in vivo via the switch of apoptosis-to-pyroptosis, which was associated with the NF-κB signaling pathway. In addition, L61H10 had no obvious side effects both in vitro and in vivo. In brief, L61H10 is shown to be a potential anti-lung cancer agent and research on its anti-tumor mechanism provides new information for chemotherapy drug research.

  • NG25, a novel inhibitor of TAK1, suppresses KRAS -mutant colorectal cancer
           growth in vitro and in vivo
    • Authors: Qizhao Ma; Ling Gu; Shiping Liao; Yanjiang Zheng; Shu Zhang; Yueyan Cao; Ji Zhang; Yufang Wang
      Abstract: KRAS mutations are one of the most prevalent genetic alterations in colorectal cancer (CRC). Although directly targeting KRAS still is a challenge in anti-cancer therapies, alternatively inhibiting KRAS related signaling pathways has been approached effectively. Here we firstly reported that MAP kinase, transforming growth factor-β-activated kinase 1 (TAK1), commonly expressed in CRC cell lines and significantly associated with KRAS mutation status. Inhibition of TAK1 by the small molecular inhibitor NG25 could inhibit CRC cells proliferation in vitro and in vivo, especially in KRAS-mutant cells. NG25 induced caspase-dependent apoptosis in KRAS-mutant cells and in orthotopic CRC mouse models by regulating the B-cell lymphoma-2 (Bcl-2) family and the inhibitor of apoptosis protein (IAP) family. Besides inhibiting molecules downstream of MAPK, including ERK, JNK and p38 phosphorylation, NG25 could block NF-κB activation in KRAS-mutant cells. As a target gene of NF-κB, down-regulated XIAP expression may be not only involved in apoptosis induced by NG25, but also reducing the formation of TAK1-XIAP complex that can activate TAK1 downstream signaling pathways, which forms a positive feedback loop to further induce apoptosis in KRAS-mutant CRC cells. Together, these findings indicated that TAK1 is an important kinase for survival of CRCs harboring KRAS mutations, and that NG25 may be a potential therapeutic strategy for KRAS-mutant CRC.

  • Correlation between microbes and colorectal cancer: tumor apoptosis is
           induced by sitosterols through promoting gut microbiota to produce
           short-chain fatty acids
    • Authors: Hang Ma; Yang Yu; Meimei Wang; Zhaoxing Li; Heshan Xu; Cheng Tian; Jian Zhang; Xiaoli Ye; Xuegang Li
      Abstract: The diversity of the bacterial community in the gut is closely related to human health. Gut microbes accomplish multiple physiological and biochemical functions. Sitosterols are a series of phytochemicals that have multiple pharmacological activities and are used as cholesterol-lowering drugs in clinical practice. In this study, we investigated the roles of bacteria and short-chain fatty acids (SCFAs) to the anti-colorectal cancer (anti-CRC) effects of sitosterols in BALB/c nude mice. Sitosterols were administered orally and gut microbiota composition and intestinal SCFAs changes were analyzed. The correlation between gut microbiota, SCFAs, and tumor apoptosis was assessed by a series of in vivo and in vitro experiments. Tumor growth in the mice was inhibited by sitosterol-treatment. Mechanistic studies revealed that sitosterol-treatment reduced the expression of PI3K/Akt, promoted the activation of Bad, decreased Bcl-xl, and enhanced cyto-c release, leading to caspase-9 and caspase-3 activation, PARP cleavage, and apoptosis. 16S rDNA analysis revealed that the diversity of microbiota, particularly phyla Bacteroidetes and Firmicutes, reduced dramatically in the gut of tumor-bearing mice, whilst treatment with sitosterols reversed these changes. The levels of SCFAs in the fecal samples of sitosterol-treated mice increased, leading to cancer cell apoptosis in vitro. Moreover, tumor apoptosis was induced after mice received a daily dose of 2 × 108 CFU/0.2 mL Lactobacillus pentosus or 20 mM/0.2 mL SCFAs. Taken together, these results demonstrate that sitosterols maintain a diverse microbial environment and enrich the content of L. pentosus in the gut, leading to the production of beneficial metabolites including SCFAs that promote tumor apoptosis.

      Abstract: Apoptosis is an important and necessary cell death program which promotes homeostasis and organismal survival. When dysregulated, however, it can lead to a myriad of pathologies from neurodegenerative diseases to cancer. Apoptosis is therefore the subject of intense study aimed at dissecting its pathways and molecular mechanisms. Although many assay methods exist for confirming whether an apoptotic response has occurred in vitro, most methods are destructive and involve laborious operator effort or specialized instrumentation. Here we describe a real-time, no-wash, microplate method which utilizes recombinant annexin V fusion proteins containing evolved binary subunits of NanoBiT™ luciferase. The fusion proteins, a time-released enzymatic substrate, a necrosis detection dye and exogenous calcium ions are delivered via an optimized and physiologically inert reagent directly to cells in culture at the time of treatment or dosing. Luminescent signals proportional to phosphatidylserine (PS) exposure and fluorescent signals generated as a result of loss of membrane integrity are then collected using a standard multimode plate reader at scheduled intervals over the exposure. The resulting luminescent and fluorescent data are then used to define the kinetics and magnitude of an apoptotic response. This study details our efforts to develop, characterize, and demonstrate the features of the assay by providing relevant examples from diverse cell models for programmed cell death.

  • Molecular mechanisms of apoptosis and autophagy elicited by combined
           treatment with oridonin and cetuximab in laryngeal squamous cell carcinoma
    • Authors: Shijie Cao; Yiyuan Huang; Qiang Zhang; Fangjin Lu; Paul Owusu Donkor; Yan Zhu; Feng Qiu; Ning Kang
      Abstract: Combined oridonin (ORI), a natural and safe kaurene diterpenoid isolated from Rabdosia rubescens, and cetuximab (Cet), an anti-EGFR monoclonal antibody, have been reported to exert synergistic anti-tumor effects against laryngeal squamous cell carcinoma (LSCC) both in vitro and in vivo by our group. In the present study, we further found that ORI/Cet treatment not only resulted in apoptosis but also induced autophagy. AMPK/mTOR signaling pathway was found to be involved in the activation of autophagy in ORI/Cet-treated LSCC cells, which is independent of p53 status. Additionally, chromatin immunoprecipitation (ChIP) assay showed that ORI/Cet significantly increased the binding NF-κB family member p65 with the promotor of BECN 1, and p65-mediated up-regulation of BECN 1 caused by ORI/Cet is coupled to increased autophagy. On the other hand, we demonstrated that either Beclin 1 SiRNA or autophagy inhibitors could increase ORI/Cet induced-apoptosis, indicating that autophagy induced by combination of the two agents plays a cytoprotective role. Interestingly, 48 h after the combined treatment, autophagy began to decrease but apoptosis was significantly elevated. Our findings suggest that autophagy might be strongly associated with the antitumor efficacy of ORI/Cet, which may be beneficial to the clinical application of ORI/Cet in LSCC treatment.

  • PPPDE1 promotes hepatocellular carcinoma development by negatively
           regulate p53 and apoptosis
    • Authors: Xingwang Xie; Xueyan Wang; Weijia Liao; Ran Fei; Nan Wu; Xu Cong; Qian Chen; Lai Wei; Yu Wang; Hongsong Chen
      Abstract: We have previously identified that PPPDE1 is a deubiquitinase (DUB) belonging to a cysteine isopeptidase family. Here we sought to explore the biological significance of PPPDE1 in hepatocellular carcinoma and its underlying molecular mechanism. In the present study, we found that amplification and overexpression of PPPDE1 were associated with poor prognosis in hepatocellular carcinoma (HCC). We also demonstrated that knocking down of PPPDE1 could significantly block the clonal growth and tumorigenicity of human HCC cells, which revealed a critical role for PPPDE1 in HCC development. Furthermore, we proved that PPPDE1 is a key modulator of p53 protein level and its down stream apoptosis pathway. Taken together, these results suggested that PPPDE1 is a putative HCC driver gene and extensive studies should be conducted in the future to investigate the role of PPPDE1 in HCC and other tumors.

  • Ready player one' Autophagy shapes resistance to photodynamic therapy
           in cancers
    • Authors: Xian Duan; Bo Chen; Yanan Cui; Lin Zhou; Chenkai Wu; Zhulin Yang; Yu Wen; Xiongying Miao; Qinglong Li; Li Xiong; Jun He
      Abstract: Photodynamic therapy (PDT) is a procedure used in cancer therapy that has been shown to be useful for certain indications. Considerable evidence suggests that PDT might be superior to conventional modalities for some indications. In this report, we examine the relationship between PDT responsiveness and autophagy, which can exert a cytoprotective effect. Autophagy is an essential physiological process that maintains cellular homeostasis by degrading dysfunctional or impaired cellular components and organelles via a lysosome-based pathway. Autophagy, which includes macroautophagy and microautophagy, can be a factor that decreases or abolishes responses to various therapeutic protocols. We systematically discuss the mechanisms underlying cell-fate decisions elicited by PDT; analyse the principles of PDT-induced autophagy, macroautophagy and microautophagy; and present evidence to support the notion that autophagy is a critical mechanism in resistance to PDT. A combined strategy involving autophagy inhibitors may be able to further enhance PDT efficacy. Finally, we provide suggestions for future studies, note where our understanding of the relevant molecular regulators is deficient, and discuss the correlations among PDT-induced resistance and autophagy, especially microautophagy.

  • Inhibition of the ubiquitination of HSF1 by FBXW7 protects the intestine
           against ischemia–reperfusion injury

      Abstract: Epithelial apoptosis is an important factor in intestinal ischemia–reperfusion (I/R) injury. Heat shock factor 1 (HSF1) is a classical stress response factor that directly regulates the transcription of heat shock proteins (HSPs) under stress conditions. Although HSPs are involved in protecting the intestine against I/R, the mechanism whereby HSF1 is regulated in I/R is poorly understood. Here, we show that the ubiquitin ligase FBXW7 targets HSF1 for ubiquitination and degradation in intestinal I/R. In this study, we found that FBXW7 expression was upregulated at the transcriptional level in intestinal mucosae subjected to I/R. In Caco-2 and IEC-6 cells subjected to hypoxia/reoxygenation (H/R), a high FBXW7 level led to excessive HSF1 ubiquitination and degradation. FBXW7 knockdown attenuated HSF1 ubiquitination and downregulation and accelerated HSPB1 and HSP70 expression. In addition, FBXW7 deletion alleviated the apoptosis of intestinal epithelial cells, as evidenced by decreased activation of caspase-3 and caspase-9. The results suggest that FBXW7 suppression protects against intestinal I/R, at least partly through the HSF1/HSP pathway. These findings indicate that FBXW7 may be a potential therapeutic target for inhibiting intestinal mucosa apoptosis during intestinal I/R.

  • Mechanisms of monocyte cell death triggered by dengue virus infection
    • Authors: Jorge Andrés Castillo; Silvio Urcuqui-Inchima
      Abstract: Arthropod-borne viral diseases caused by dengue virus (DENV) are major re-emerging public health problem worldwide. In spite of intense research, DENV pathogenesis is not fully understood and remains enigmatic; however, current evidence suggests that dengue progression is associated with an inflammatory response, mainly in patients suffering from a second DENV infection. Monocytes are one of the main target cells of DENV infection and play an important role in pathogenesis since they are known to produce several inflammatory cytokines that can lead to endothelial dysfunction and therefore vascular leak. In addition, monocytes play an important role in antibody dependent enhancement, infection with consequences in viral load and immune response. Despite the physiological functions of monocytes in immune response, their life span in the bloodstream is very short, and activation of monocytes by DENV infection can trigger different types of cell death. For example, DENV can induce apoptosis in monocytes related with the production of Tumor necrosis factor alpha (TNF-α). Additionally, recent studies have shown that DENV-infected monocytes also exhibit a cell death process mediated by caspase-1 activation together with IL-1 production, referred to as pyroptosis. Taken together, the aforementioned studies strongly depict that multiple cell death pathways may be occurring in monocytes upon DENV-2 infection. This review provides insight into mechanisms of DENV-induced death of both monocytes and other cell types for a better understanding of this process. Further knowledge in cell death induced by DENV will help in the developing novel strategies to prevent disease progression.

  • Augmenter of liver regeneration promotes mitochondrial biogenesis in renal
           ischemia–reperfusion injury
    • Authors: Li-li Huang; Rui-ting Long; Gui-ping Jiang; Xiao Jiang; Hang Sun; Hui Guo; Xiao-hui Liao
      Abstract: Mitochondria are the center of energy metabolism in the cell and the preferential target of various toxicants and ischemic injury. Renal ischemia–reperfusion (I/R) injury triggers proximal tubule injury and the mitochondria are believed to be the primary subcellular target of I/R injury. The promotion of mitochondrial biogenesis (MB) is critical for the prevention I/R injury. The results of our previous study showed that augmenter of liver regeneration (ALR) has anti-apoptotic and anti-oxidant functions. However, the modulatory mechanism of ALR remains unclear and warrants further investigation. To gain further insight into the role of ALR in MB, human kidney (HK)-2 cells were treated with lentiviruses carrying ALR short interfering RNA (siRNA) and a model of hypoxia reoxygenation (H/R) injury in vitro was created. We observed that knockdown of ALR promoted apoptosis of renal tubular cells and aggravated mitochondrial injury, as evidenced by the decrease in the mitochondrial respiratory proteins adenosine triphosphate (ATP) synthase subunit β, cytochrome c oxidase subunit 1, and nicotinamide adenine dinucleotide dehydrogenase (ubiquinone) beta subcomplex 8. Meanwhile, the production of reactive oxygen species was increased and ATP levels were decreased significantly in HK-2 cells, as compared with the siRNA/control group (p < 0.05). In addition, the mitochondrial DNA copy number and membrane potential were markedly decreased. Furthermore, critical transcriptional regulators of MB (i.e., peroxisome proliferator-activated receptor-gamma coactivator 1 alpha, mitochondrial transcription factor A, sirtuin-1, and nuclear respiratory factor-1) were depleted in the siRNA/ALR group. Taken together, these findings unveil essential roles of ALR in the inhibition of renal tubular cell apoptosis and attenuation of mitochondrial dysfunction by promoting MB in AKI.

      Abstract: The transcription factor p53 suppresses tumor growth by inducing nucleated cell apoptosis and cycle arrest. Because of its influence on primitive erythroid cell differentiation and survival, p53 is an important determinant of erythropoiesis. However, the impact of p53 on the fate of erythrocytes, cells lacking nucleus and mitochondria, during their post-maturation phase in the circulation remained elusive. Erythrocyte survival may be compromised by suicidal erythrocyte death or eryptosis, which is hallmarked by phosphatidylserine translocation and stimulated by increase of cytosolic Ca2+ concentration. Here, we comparatively examined erythrocyte homeostasis in p53-mutant mice (Trp53tm1Tyj/J) and in corresponding WT mice (C57BL/6J) by analyzing eryptosis and erythropoiesis. To this end, spontaneous cell membrane phosphatidylserine exposure and cytosolic Ca2+ concentration were higher in erythrocytes drawn from Trp53tm1Tyj/J mice than from WT mice. Eryptosis induced by glucose deprivation, a pathophysiological cell stressor, was slightly, but significantly more prominent in erythrocytes drawn from Trp53tm1Tyj/J mice as compared to WT mice. The loss of erythrocytes by eryptosis was fully compensated by enhanced erythropoiesis in Trp53tm1Tyj/J mice, as reflected by increased reticulocytosis and abundance of erythroid precursor cells in the bone marrow. Accordingly, erythrocyte number, packed cell volume and hemoglobin were similar in Trp53tm1Tyj/J and WT mice. Taken together, functional p53 deficiency enhances the turnover of circulating erythrocytes by parallel increase of eryptosis and stimulated compensatory erythropoiesis.

  • LncRNA-135528 inhibits tumor progression by up-regulating CXCL10 through
           the JAK/STAT pathway
    • Authors: Peng Wang; Xiaobin Peng; Jingjing Zhang; Zhen Wang; Jiaxue Meng; Bohong Cen; Aimin Ji; Shuai He
      Abstract: Spontaneous tumor regression can be observed in many tumors, however, studies related to the altered expression of lncRNA in spontaneous glioma regression are limited, and the potential contributions of lncRNAs to spontaneous glioma regression remain unknown. To investigate the biological roles of lncRNA-135528 in spontaneous glioma regression. The cDNA fragment of lncRNA-135528 was obtained by rapid-amplification of cDNA ends (RACE) technology and cloned into the plvx-mcmv-zsgreen-puro vector. Additionally, we stably silenced or overexpressed lncRNA-135528 in G422 cells by transfecting with siRNA against lncRNA-135528 or lncRNA-135528 overexpression plasmid. Then, we examined lncRNA-135528 overexpressing and lncRNA-135528 silencing on glioma cells and its effects on CXCL10 and JAK/STAT pathways. The main findings indicated that lncRNA-135528 promoted glioma cell apoptosis, inhibited cell proliferation and arrested cell cycle progression; the up-regulation of lncRNA135528 led to significantly increased CXCL10 levels and the differential expression of mRNA associated with JAK/STAT pathway in glioma cells. lncRNA-135528 can inhibit tumor progression by up-regulating CXCL10 through the JAK/STAT pathway.

  • Molecular targeting of breast and colon cancer cells by PAR1 mediated
           apoptosis through a novel pro-apoptotic peptide
    • Authors: Tanusree Ray; Dwiprohi Kar; Ananda Pal; Shravanti Mukherjee; Chandrima Das; Amit Pal
      Abstract: A novel activating peptide was designed and synthesized from V. cholerae hemagglutinine protease (HAP) mediated cleavage site of mouse PAR1. The peptide “PFISED” interacts with PAR1 in a new site which is different from its thrombin mediated conventional activation site and induced a series of new downstream signaling pathways. The peptide showed apoptosis in human and mouse breast (MCF-7 and EAC) and colon (HT29 and CT26) cancer cells where as in the same peptide concentration in normal human breast epithelial cells (MCF-10A), normal human fibroblast cells (MRC-5), normal mouse peritoneal macrophage cells and normal mouse breast and colon tissues did not show any effect. Treatment with this peptide enhanced the survival kinetics of EAC induced mice. The peptide mediated apoptosis was inhibited in presence of PAR1 inhibitor and was significantly reduced in si-PAR1 treated cells that indicate the activating peptide “PFISED” induced PAR1 mediated apoptosis of colon and breast cancer cells. This peptide induced over expression and activation of PAR1 and its downstream MAP kinase and NFκB signaling pathways. These signaling pathways enhanced the cellular ROS level to kill malignant cells. We report a novel pro-apoptotic peptide which can selectively kill malignant cells via its specific target receptor PAR1 which is over expressed in the malignant cells and can be used as a molecular target therapy for cancer treatment.

  • N -(3-oxo-acyl) homoserine lactone induced germ cell apoptosis and
           suppressed the over-activated RAS/MAPK tumorigenesis via
           mitochondrial-dependent ROS in C. elegans
    • Authors: Bin Chen; Xianbin Cao; Huayi Lu; Pengbo Wen; Xiaojing Qi; Shaopeng Chen; Lijun Wu; Chi Li; An Xu; Guoping Zhao
      Abstract: As a quorum-sensing molecule for bacteria–bacteria communication, N-(3-oxododecanoyl)-homoserine lactone (C12) has been found to possess pro-apoptotic activities in various cell culture models. However, the detailed mechanism of how this important signaling molecule function in the cells of live animals still remains largely unclear. In this study, we systematically investigated the mechanism for C12-mediated apoptosis and studied its anti-tumor effect in Caenorhabditis elegans (C. elegans). Our data demonstrated that C12 increased C. elegans germ cell apoptosis, by triggering mitochondrial outer membrane permeabilization (MOMP) and elevating the reactive oxygen species (ROS) level. Importantly, C12-induced ROS increased the expression of genes critical for DNA damage response (hus-1, clk-2 and cep-1) and genes involved in p38 and JNK/MAPK signaling pathway (nsy-1, sek-1, pmk-1, mkk-4 and jnk-1). Furthermore, C12 failed to induce germ cell apoptosis in animals lacking the expression of each of those genes. Finally, in a C. elegans tumor-like symptom model, C12 significantly suppressed tumor growth through inhibiting the expression of RAS/MAPK pathway genes (let-23/EGFR, let-60/RAS, lin-45/RAF, mek-2/MEK and mpk-1/MAPK). Overall, our results indicate that DNA damage response and MAPK activation triggered by mitochondrial ROS play important roles in C12-induced apoptotic signaling in C. elegans, and RAS/MAPK suppression is involved in the tumor inhibition effect of C12. This study provides in vivo evidence that C12 is a potential candidate for cancer therapeutics by exerting its pro-apoptotic and anti-tumor effects via elevating mitochondria-dependent ROS production.

  • Targeting autophagy for combating chemoresistance and radioresistance in
    • Authors: Matthew A. Taylor; Bhaskar C. Das; Swapan K. Ray
      Abstract: Autophagy is an evolutionarily conserved catabolic process that plays an essential role in maintaining cellular homeostasis by degrading unneeded cell components. When exposed to hostile environments, such as hypoxia or nutrient starvation, cells hyperactivate autophagy in an effort to maintain their longevity. In densely packed solid tumors, such as glioblastoma, autophagy has been found to run rampant due to a lack of oxygen and nutrients. In recent years, targeting autophagy as a way to strengthen current glioblastoma treatment has shown promising results. However, that protective autophagy inhibition or autophagy overactivation is more beneficial, is still being debated. Protective autophagy inhibition would lower a cell’s previously activated defense mechanism, thereby increasing its sensitivity to treatment. Autophagy overactivation would cause cell death through lysosomal overactivation, thus introducing another cell death pathway in addition to apoptosis. Both methods have been proven effective in the treatment of solid tumors. This systematic review article highlights scenarios where both autophagy inhibition and activation have proven effective in combating chemoresistance and radioresistance in glioblastoma, and how autophagy may be best utilized for glioblastoma therapy in clinical settings.

  • MiRNA-126 expression inhibits IL-23R mediated TNF-α or IFN-γ production
           in fibroblast-like synoviocytes in a mice model of collagen-induced
           rheumatoid arthritis
    • Authors: Jie Gao; Ruina Kong; Xiaoli Zhou; Lianmei Ji; Ju Zhang; Dongbao Zhao
      Abstract: Both miR-126 and IL-23R affect rheumatoid arthritis (RA) procession. This study aimed to investigate the association of miR-126 and IL-23R and the possible modulation of miR-126 to RA pathogenesis. Serum, synovial tissue and synovial fluid were collected from patients with RA, and expression of miR-126, IL-23R, TNF-α and IFN-γ were detected. Fibroblast-like synoviocytes (FLS) was established using a collagen-induced arthritis mice model. The expression of miR-126 was manual intervened using pro-miR-126 and anti-miR-126 encoding lentivirus plasmids, or miR-126 agonists and corresponding negative controls. MiR-126 expression was inhibited in RA patients when compared with controls (P < 0.05). TNF-α and IFN-γ production and IL-23R expression were significantly upregulated in RA patients when compared to controls (P < 0.05). In pro-miR-126 treated FLS cells, the administration of pro-miR-126 plasmids upregulated miR-126, but inhibited IL-23R, TNF-α and IFN-γ expression or production. Moreover, the miR-126 agonist reversed the effects of the anti-miR-126 plasmid on FLS. These results revealed that miR-126 negative regulated the expression of IL-23R, TNF-α and IFN-γ. These results suggest the key impact of miR-126 on RA procession. Moreover, pro-miR-126 might be explored to be a potential therapy for RA.
