1LMM5.1 and LMM5.4,two eukaryotic translation elongation factor 1Alike gene family members,negatively affect cell death and disease resistance in rice显示文摘Lesion mimic mutant(LMM) genes, stimulating lesion formation in the absence of pathogens, play significant roles in immune response. In this study, we characterized a rice lesion mimic mutant, lmm5,which displayed light-dependent spontaneous lesions. Additionally, lmm5 plants exhibited enhanced resistance to all of the tested races of Magnaporthe oryzae and Xanthomonas oryzae pv. oryzae(Xoo) by increasing the expression of defense-related genes and the accumulation of hydrogen peroxide. Genetic analysis showed that the lesion mimic phenotype of lmm5 was controlled by two genes, lmm5.1 and lmm5.4, which were isolated with a map-based cloning strategy. Remarkably, LMM5.1 and LMM5.4 share a 97.4% amino acid sequence identity, and they each encode a eukaryotic translation elongation factor 1A(e EF1A)-like protein. Besides, LMM5.1 and LMM5.4 were expressed in a tissue-specific and an indicaspecific manner, respectively. In addition, high-throughput m RNA sequencing analysis confirmed that the basal immunity was constitutively activated in the lmm5 mutant. Taken together, these results suggest that the homologous e EF1A-like genes, LMM5.1 and LMM5.4, negatively affect cell death and disease resistance in rice.Jiying Zhao Pengcheng Liu Chunrong Li Yanyan Wang Lequn Guo Guanghuai Jiang Wenxue Zhai 2017Journal of Genetics and Genomics2017,44,2:10
2Multi-omics analyses of 398 foxtail millet accessions reveal genomic regions associated with domestication,metabolite traits,and antiinflammatory effects显示文摘Foxtail millet(Setaria italica),which was domesticatedfromthewild speciesgreenfoxtail(Setaria viridis),isa richsource of phytonutrientsfor humans.To evaluate how breeding changed themetabolome offoxtail millet grains,we generated and analyzed the datasets encompassing the genomes,transcriptomes,metabolomes,and anti-inflammatory indices from 398 foxtail millet accessions.We identified hundreds of common variants that influence numerous secondary metabolites.We observed tremendous differences in natural variations of the metabolites and their underlying genetic architectures between distinct sub-groups of foxtail millet.Furthermore,we found that the selection of the gene alleles associated with yellow grains led to altered profiles of metabolites such as carotenoids and endogenous phytohormones.Using CRiSPR-mediated genome editing wevalidated the function of PHYTOENE SYNTHASE1(PSY1)gene in affecting milletgrain colorand quality.Interestingly,our in vitro cell inflammation assays showed that 83 metabolites in millet grains have anti-inflammatory effects.Taken together,ourmulti-omics study illustrates how the breeding history of foxtail millet has shaped its metabolite profile.The datasets we generated in this study also provide important resources for further understanding how millet grain quality is affected by different metabolites,laying the foundations for future millet genetic research and metabolome-assisted improvement.Xukai Li Jianhua Gao Jingyi Song Kai Guo Siyu Hou Xingchun Wang Qiang He Yanyan Zhang Yakun Zhang Yulu Yang Jiaoyan Tang Hailang Wang Staffan Persson Mingquan Huang Lishuai Xu Linlin Zhong Dongqin Li Yongming Liu Hua Wu Xianmin Diao Peng Chen Xiaowen Wang Yuanhuai Han 2022Molecular Plant2022,15,8:8
3Exosomes with low miR-34c-3p expression promote invasion and migration of non-small cell lung cancer by upregulating integrinα2β1显示文摘Exosomes play critical roles in regulating various physiological and pathological processes,including immune stimulation,immune suppression,cardiovascular diseases,and cancers.Recent studies show that exosomes that transport specific microRNAs(miRNAs)are involved in tumor development.However,the molecular mechanism by which tumor invasion and migration are regulated by exosomes from non-small cell lung cancer(NSCLC)is not well understood.Here,we show that exosomes shuttling low levels of miR-34c-3p are involved in NSCLC progression.Our results showed that exosomes derived from NSCLC cells carrying low levels of miR-34c-3p could be transported into the cytoplasm of NSCLC cells and accelerate NSCLC invasion and migration by upregulating integrinα2β1.A luciferase assay revealed that integrinα2β1 was the direct target of miR-34c-3p,and overexpression of integrinα2β1 could promote the invasion and migration of NSCLC cells.The analysis of exosomes derived from clinical serum samples indicated that the expression of miR-34c-3p was significantly downregulated in exosomes from NSCLC patients compared with that of normal controls.A549-derived exosomes promoted NSCLC cells lung metastases in vivo.Exosomes shuttling low levels of miR-34c-3p were associated with the progression of NSCLC in vitro and in vivo.Our data demonstrate that exosomes shuttling low levels of miR-34c-3p can accelerate the invasion and migration of NSCLC by upregulating integrinα2β1.MiR-34c-3p can be a diagnostic and prognostic marker for NSCLC.High expression of integrinα2β1 is positively related to the migration and metastasis of NSCLC cells.Wenjing Huang Yanyan Yan Yun Liu Minting Lin Jinxiang Ma Wei Zhang Jianwei Dai Jiajun Li Qiaoru Guo Hubiao Chen Bolat Makabel Hong Liu Chaoyue Su Hong Bi Jianye Zhang 2020Signal Transduction and Targeted Therapy2020,5,1:5
4Protective effects of curcumin against human immunodeficiency virus 1 gp120 V3 loop-induced neuronal injury in rats显示文摘Curcumin improves the learning and memory deficits in rats induced by the gp120 V3 loop. The present study cultured rat hippocampal neurons with 1 nM gp120 V3 loop and 1 μM curcumin for 24 hours. The results showed that curcumin inhibited the gp120 V3 loop-induced mitochondrial membrane potential decrease, reduced the mRNA expression of the pro-apoptotic gene caspase-3, and attenuated hippocampal neuronal injury.Zheng Gong Lijuan Yang Hongmei Tang Rui Pan Sai Xie Luyan Guo Junbin Wang Qinyin Deng Guoyin Xiong Yanyan Xing Jun Dong 2012Neural Regeneration Research2012,7,3:5
5Regulative effect of Taohong Siwu decoction(桃红四物汤) on extracellular matrix of endometrium in drug-induced abortion显示文摘OBJECTIVE: To explore the effects of Taohong Siwu decoction(桃红四物汤, THSWD) on the extracellular matrix of endometrium in rats following drug-induced abortion.METHODS: Thirty-six pregnant female rats were administered mifepristone and misoprostol to induce abortion, and amounts of uterine bleeding were recorded. Pathological damage and collagen accumulation were detected by hematoxylin-eosin staining and Masson’s trichrome staining in uterus, respectively. Myeloperoxidase was evaluated by immunohistochemistry.The expression levels of fibronectin, laminin, matrix metalloproteinase 9(MMP-9), and tissue inhibitor of metalloproteinase 1(TIMP-1) were quantified using western blotting.RESULTS: THSWD could promote endometrial protection in rats following drug-induced abortion.The contents of cellulose and myeloperoxidase were significantly decreased in uterine tissue of THSWD-treated groups. Moreover, THSWD significantly decreased the expression levels of fibronectin, laminin, and TIMP-1. THSWD also significantly increased MMP-9 expression and the MMP-9/TIMP-1 ratio.CONCLUSION: THSWD plays a critical role in endometrial protection by reducing extracellular matrix deposition and uterine fibrosis. These effects may have been achieved by increasing MMP-9, reducing TIMP-1, and/or altering the ratio of MMP-9/TIMP-1.WANG Mengmeng GUO Dongdong HAN Lan PENG Daiyin CHEN Weidong ZHANG Yanyan 2021Journal of Traditional Chinese Medicine2021,41,1:5
6Optimization of Thermoelectric Microwave Power Sensors Based on Thin-Membrane Structure显示文摘In this work, the thermal conduction property of thermoelectric microwave power sensors is researched. The fabrication of the thermoelectric microwave power sensor consists of a front side and a back side processing using Ga As Monolithic microwave integrated circuit(MMIC) process and MEMS technology. An isolation structure on the front side is designed to prevent the thermal conduction from the resistor to the Coplanar waveguide(CPW). A thin-membrane on the back side is designed to prevent the thermal conduction from the resistor to the substrate. For the microwave power sensor without an isolation structure, the sensitivity is about 0.138, 0.136,0.132, 0.115 and 0.111 m V/m W at 8, 9, 10, 11 and 12 GHz,respectively. For the microwave power sensor with an isolation structure, the sensitivity is about 0.142, 0.139, 0.135,0.117 and 0.115 m V/m W at 8, 9, 10, 11 and 12 GHz, respectively. As a result, the higher thermal conduction efficiency and the higher sensitivity are obtained for the optimized thermoelectric microwave power sensors.WANG Debo GAO Bo ZHAO Jiang ZHANG Yi GUO Yanyan 2015Chinese Journal of Electronics2015,24,4:5
7An antioxidant system through conjugating superoxide dismutase onto metal-organic framework for cardiac repair显示文摘Acute myocardial infarction(AMI)remains a dominant origin of morbidity,mortality and disability worldwide.Increases in reactive oxygen species(ROS)are key contributor to excessive cardiac injury after AMI.Here we developed an immobilized enzyme with Superoxide Dismutase(SOD)activity cross-link with Zr-based metal-organic framework(ZrMOF)(SOD-ZrMOF)for mitigate ROS-caused injury.In vitro and in vivo evidence indicates that SOD-ZrMOF exhibits excellent biocompatibility.By efficiently scavenging ROS and suppressing oxidative stress,SOD-ZrMOF can protect the function of mitochondria,reduce cell death and alleviate inflammation.More excitingly,long-term study using an animal model of AMI demonstrated that SOD-ZrMOF can reduce the infarct area,protect cardiac function,promote angiogenesis and inhibit pathological myocardial remodeling.Therefore,SOD-ZrMOF holds great potential as an efficacious and safe nanomaterial treatment for AMI.Jiacheng Guo Zhenzhen Yang Yongzheng Lu Chunyan Du Chang Cao Bo Wang Xiaoting Yue Zenglei Zhang Yanyan Xu Zhen Qin Tingting Huang Wei Wang Wei Jiang Jinying Zhang Junnan Tang 2022Bioactive Materials2022,7,4:4
8AFAP1-AS1: a rising star among oncogenic long non-coding RNAs显示文摘Long non-coding RNAs(lncRNAs)have become a hotspot in biomedical research.This interest reflects their extensive involvement in the regulation of the expression of other genes,and their influence on the occurrence and development of a variety of human diseases.Actin filament associated protein 1-Antisense RNA 1(AFAP1-AS1)is a recently discovered oncogenic lncRNA.It is highly expressed in a variety of solid tumors,and regulates the expression of downstream genes and signaling pathways through adsorption and competing microRNAs,or by the direct binding to other proteins.Ultimately,AFAP1-AS1 promotes proliferation,chemotherapy resistance,and resistance to apoptosis,maintains stemness,and enhances invasion and migration of tumor cells.This paper summarizes the research concerning AFAP1-AS1 in malignant tumors,including the clinical application prospects of AFAP1-AS1 as a potential molecular marker and therapeutic target of malignant tumors.We also discuss the limitations in the knowledge of AFAP1-AS1 and directions of further research.AFAP1-AS1 is expected to provide an example for studies of other lncRNA molecules.Fang Xiong Kunjie Zhu Su Deng Hongbin Huang Liting Yang Zhaojian Gong Lei Shi Yi He Yanyan Tang Qianjin Liao Jianjun Yu Xiaoling Li Yong Li Guiyuan Li Zhaoyang Zeng Wei Xiong Shanshan Zhang Can Guo 2021Science China(Life Sciences)2021,64,10:4
9Initial scalar lithospheric magnetic anomaly map of China and surrounding regions derived from CSES satellite data显示文摘The China Seismo-Electromagnetic Satellite(CSES),China’s first satellite to measure geophysical fields with scientific goals in both space and solid earth physics,was launched successfully in February 2018.It carries high-precision magnetometers to measure the geomagnetic field.In this study,the CSES magnetic data were used to extract the signal of the lithospheric magnetic field caused by magnetized rocks in the crust and uppermost mantle.First,an along-track analysis of the CSES magnetic data was undertaken near the Bangui magnetic anomaly in central Africa and the Tarim magnetic anomaly in China,demonstrating that the CSES magnetic data are indeed sensitive to the lithospheric magnetic anomaly field.Then a lithospheric magnetic anomaly map over China and surrounding regions was derived.This map is consistent with the lithospheric part of the CHAOS-7 model.In particular,it clearly reveals four major magnetic anomalies containing long-wavelength signals at the altitude of lowearth-orbiting satellites.Three magnetic highs are located over the Tarim,Sichuan and Songliao basin,the origins of which could be related to large-scale tectonic-magmatic activities during geological history.A prominent magnetic low is otherwise found in the southern Himalayan-Tibetan plateau,possibly caused by the shallow Curie depth in this region.To further improve the precision of the lithospheric magnetic field model,more detailed data processing and multi-source data merging are needed.WANG Jie SHEN XuHui YANG YanYan ZEREN ZhiMa HULOT Gauthier OLSEN Nils ZHOU Bin MAGNES Werner DE SANTIS Angelo HUANG JianPing GUO Feng LIU WenLong YU JingBo 2021Science China(Technological Sciences)2021,64,5:4
10Taurine Transporter dEAAT2 is Required for Auditory Transduction in Drosophila显示文摘Drosophila dEAAT2, a member of the excitatory amino-acid transporter(EAAT) family, has been described as mediating the high-affinity transport of taurine, which is a free amino-acid abundant in both insects and mammals. However, the role of taurine and its transporter in hearing is not clear. Here, we report that dEAAT2 is required for the larval startle response to sound stimuli. d EAAT2 was found to be enriched in the distal region of chordotonal neurons where sound transduction occurs. The Ca^(2+) imaging and electrophysiological results showed that disrupted dEAAT2 expression significantly reduced the response of chordotonal neurons to sound.More importantly, expressing d EAAT2 in the chordotonal neurons rescued these mutant phenotypes. Taken together,these findings indicate a critical role for Drosophila dEAAT2 in sound transduction by chordotonal neurons.Ying Sun Yanyan Jia Yifeng Guo Fangyi Chen Zhiqiang Yan 2018Neuroscience Bulletin2018,34,6:4
11Inhibiting Hv1 channel in peripheral sensory neurons attenuates chronic inflammatory pain and opioid side effects显示文摘Both opioids and nonsteroidal anti-inflammatory drugs(NSAIDS)produce deleterious side effects and fail to provide sustained relief in patients with chronic inflammatory pain.Peripheral neuroinflammation(PN)is critical for initiation and development of inflammatory pain.A better understanding of molecular mechanisms underlying PN would facilitate the discovery of new analgesic targets and the development of new therapeutics.Emerging evidence suggests that peripheral sensory neurons are not only responders to painful stimuli,but are also actively engaged in inflammation and immunity,whereas the intrinsic regulatory mechanism is poorly understood.Here we report the expression of proton-selective ion channel Hv1 in peripheral sensory neurons in rodents and humans,which was previously shown as selectively expressed in microglia in mammalian central nervous system.Neuronal Hv1 was up-regulated by PN or depolarizing stimulation,which in turn aggravates inflammation and nociception.Inhibiting neuronal Hv1 genetically or by a newly discovered selective inhibitor YHV98-4 reduced intracellular alkalization and ROS production in inflammatory pain,mitigated the imbalance in downstream SHP-1-pAKT signaling,and also diminished pro-inflammatory chemokine release to alleviate nociception and morphine-induced hyperalgesia and tolerance.Thus,our data reveal neuronal Hv1 as a novel target in analgesia strategy and managing opioids-related side effects.Qiansen Zhang Yimin Ren Yiqing Mo Peipei Guo Ping Liao Yuncheng Luo Jie Mu Zhuo Chen Yang Zhang Ya Li Linghui Yang Daqing Liao Jie Fu Juwen Shen Wei Huang Xuewen Xu Yanyan Guo Lianghe Mei Yunxia Zuo Jin Liu Huaiyu Yang Ruotian Jiang 2022Cell Research2022,32,5:3
12Detection of Huanglongbing(citrus greening) based on hyperspectral image analysis and PCR显示文摘Huanglongbing (HLB, citrus greening) is one of the most serious quarantine diseases of citrus worldwide. To monitor in real-time, recognize diseased trees, and efficiently prevent and control HLB disease in citrus, it is necessary to develop a rapid diagnostic method to detect HLB infected plants without symptoms. This study used Newhall navel orange plants as the research subject, and collected normal color leaf samples and chlorotic leaf samples from a healthy orchard and an HLB-infected orchard, respectively. First, hyperspectral data of the upper and lower leaf surfaces were obtained, and then the polymerase chain reaction (PCR) was used to detect the HLB bacterium in each leaf. The PCR test results showed that all samples from the healthy orchard were negative, and a portion of the samples from the infected orchard were positive. According to these results, the leaf samples from the orchards were divided into disease-free leaves and HLB-positive leaves, and the least squares support vector machine recognition model was established based on the leaf hyperspectral reflectance. The effect on the model of the spectra obtained from the upper and lower leaf surfaces was investigated and different pretreatment methods were compared and analyzed. It was observed that the HLB recognition rate values of the calibration and validation sets based on upper leaf surface spectra under 9-point smoothing pretreatment were 100% and 92.5%, respectively. The recognition rate values based on lower leaf surface spectra under the second-order derivative pretreatment were also 100% and 92.5%, respectively. Both upper and lower leaf surface spectra were available for recognition of HLB-infected leaves, and the HLB PCR-positive leaves could be distinguished from the healthy by the hyperspectral modeling analysis. The results of this study show that early and nondestructive detection of HLBinfected leaves without symptoms is possible, which provides a basis for the hyperspectral diagnosis of citrus with HLB.Kejian WANG Dongmei GUO Yao ZHANG Lie DENG Rangjin XIE Qiang LV Shilai YI Yongqiang ZHENG Yanyan MA Shaolan HE 2019Frontiers of Agricultural Science and Engineering2019,6,2:3
13Dual-peptide-modified alginate hydrogels for the promotion of angiogenesis显示文摘The ability to supply suitable blood vessel system is a major challenge for artificial thick tissue engineering. Angiogenesis is a key point during the process of microvascular formation. Many bioactive molecules such as extra cellular matrix(ECM) proteins and adhesion peptides derived from the ECM are applied to promote angiogenesis. In this work, two adhesion peptides, YIGSR and REDV, were selected to modify sodium alginate(ALG) to obtain YIGSR- and REDV-alginate conjugates(ALG-YIGSR, and ALG-REDV, respectively). We mixed the two peptide-conjugates together in a series of concentration ratios to prepare bioactive surfaces for in vitro studies and hydrogel scaffolds for in vivo studies. In vitro studies showed that surfaces modified with 1.09 pmol/mm2 peptide had the best affinity to human umbilical vein endothelial cells(HUVECs) than that with high or low concentrations of peptides. In addition, surfaces modified with dual peptides could significantly promote HUVECs proliferation, where ALG-YIGSR:ALG-REDV at a mole ratio of 5:1 exhibited the best enhancement ability. Furthermore, the in vivo angiogenesis results demonstrated that hydrogel scaffolds composed of mixed ALG-YIGSR and ALG-REDV at the 5:1 ratio had angiogenic induction potential by stimulating new blood vessel formation, and showed higher blood vessel density than scaffolds composed of a single peptide. These results demonstrated that a mixed combination of peptide alginate conjugates could be a potential scaffold to stimulate and induce angiogenesis in tissue engineering applications.Yanyan Yu Lei Guo Wei Wang Jina Wu Zhi Yuan 2015Science China(Information Sciences)2015,58,12:3
14A LOW-COMPLEXITY PORT SELECTION AND POWER ALLOCATION SCHEME IN DISTRIBUTION MIMO SYSTEMS显示文摘Information theoretical results have shown that Distributed Antenna Systems (DAS) can obtain higher capacity than Co-located Antenna Systems (CAS). In this paper,we investigate a downlink port selection and power allocation scheme in Distributed Multiple-Input Multiple-Output (D-MIMO) systems,where Distributed Antenna (DA) ports randomly locate in the cell. The contri-bution of this paper can be summarized as two parts. Firstly,we analyze how antenna correlation af-fects power allocation in D-MIMO systems. Secondly,based on large scale fading and antenna corre-lation,a low-complexity port selection and power allocation scheme is proposed. In the proposed scheme,we take both large scale fading and antenna correlation into consideration. Moreover,User Equipment (UE) only needs to feedback the rank of transmit antenna correlation matrix,which will not increase system complexity too much. Simulation results verify the capacity improvement based on the proposed power allocation scheme.Zhang Ningbo Kang Guixia Guo Yanyan Zhang Ping 2010Journal of Electronics(China)2010,27,2:2
15Safety and efficacy of meplazumab in healthy volunteers and COVID-19 patients: a randomized phase 1 and an exploratory phase 2 trial显示文摘Recent evidence suggests that CD147 serves as a novel receptor for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.Blocking CD147 via anti-CD147 antibody could suppress the in vitro SARS-CoV-2 replication.Meplazumab is a humanized anti-CD147 IgG_(2) monoclonal antibody,which may effectively prevent SARS-CoV-2 infection in coronavirus disease 2019(COVID-19)patients.Here,we conducted a randomized,double-blinded,placebo-controlled phase 1 trial to evaluate the safety,tolerability,and pharmacokinetics of meplazumab in healthy subjects,and an open-labeled,concurrent controlled add-on exploratory phase 2 study to determine the efficacy in COVID-19 patients.In phase 1 study,59 subjects were enrolled and assigned to eight cohorts,and no serious treatment-emergent adverse event(TEAE)or TEAE grade≥3 was observed.The serum and peripheral blood Cmax and area under the curve showed non-linear pharmacokinetic characteristics.No obvious relation between the incidence or titer of positive anti-drug antibody and dosage was observed in each cohort.The biodistribution study indicated that meplazumab reached lung tissue and maintained>14 days stable with the lung tissue/cardiac blood-pool ratio ranging from 0.41 to 0.32.In the exploratory phase 2 study,17 COVID-19 patients were enrolled,and 11 hospitalized patients were involved as concurrent control.The meplazumab treatment significantly improved the discharged(P=0.005)and case severity(P=0.021),and reduced the time to virus negative(P=0.045)in comparison to the control group.These results show a sound safety and tolerance of meplazumab in healthy volunteers and suggest that meplazumab could accelerate the recovery of patients from COVID-19 pneumonia with a favorable safety profile.Huijie Bian Zhao-Hui Zheng Ding Wei Aidong Wen Zheng Zhang Jian-Qi Lian Wen-Zhen Kang Chun-Qiu Hao Jing Wang Rong-Hua Xie Ke Dong Jie-Lai Xia Jin-Lin Miao Wen Kang Guoquan Li Di Zhang Mingru Zhang Xiu-Xuan Sun Likun Ding Kui Zhang Junfeng Jia Jin Ding Zhiqin Li Yanyan Jia Lin-Na Liu Zhe Zhang Zhao-Wei Gao Hong Du Na Yao Qing Wang Ke Wang Jie-Jie Geng Bin Wang Ting Guo Ruo Chen Yu-Meng Zhu Li-Juan Wang Qian He Rui-Rui Yao Ying Shi Xiang-Min Yang Jian-Sheng Zhou Yi-Nan Ma Ya-Tao Wang Xue Liang Fei Huo Zhe Wang Yang Zhang Xu Yang Ye Zhang Lu-Hua Gao Ling Wang Xiao-Chun Chen Hao Tang Shuang-Shuang Liu Qing-Yi Wang Zhi-Nan Chen Ping Zhu 2021Signal Transduction and Targeted Therapy2021,6,6:2
16H2 solubility and mass transfer in anthraquinone working solution: Experimental and modeling study显示文摘This work was focused on the measurement of the solubility of hydrogen(H_2) in anthraquinone working solution at temperatures of 30.0–80.0 °C and pressures of 0.2–3.0 MPa by the method of experimental and COSMO-RS model study. The influence of various factors, i.e., including pressure, temperature and solvent volume ratio, on H_2 solubility was investigated. According to the experimental results, H_2 solubility in anthraquinone working solution increases with the increase of pressure. At low pressures, the temperature had little effect on H_2 solubility while under high pressures H_2 solubility increases with increasing temperature. Henry's constant lnH has a good linear relationship with 1/T(lnH =- 1319.1/T + 9.91). The effect of volume ratio of trioctyl phosphate to trimethylbenzene on the solubility of hydrogen was studied and the results showed that increasing the amount of trimethylbenzene was conducive to the dissolution of hydrogen. In addition, there is a linear relationship between ln((P0- Pe) /(Pt- Pe)) and the time t. Gas–liquid mass transfer coefficient was obtained by calculating the slope of the line.Zhigang Lei Yaru Guo Yanyan Guo Xinxin Li Chengna Dai 2017Chinese Journal of Chemical Engineering2017,25,2:2

18BUB1B and circBUB1B_544aa aggravate multiple myeloma malignancy through evoking chromosomal instability显示文摘Multiple myeloma(MM)is an incurable plasma cell malignancy in the bone marrow characterized by chromosome instability(CIN),which contributes to the acquisition of heterogeneity,along with MM progression,drug resistance,and relapse.In this study,we elucidated that the expression of BUB1B increased strikingly in MM patients and was closely correlated with poor outcomes.Overexpression of BUB1B facilitated cellular proliferation and induced drug resistance in vitro and in vivo,while genetic targeting BUB1B abrogated this effect.Mechanistic studies unveiled that enforced expression of BUB1B evoked CIN resulting in MM poor outcomes mainly through phosphorylating CEP170.Interestingly,we discovered the existence of circBUB1B_544aa containing the kinase catalytic center of BUB1B,which was translated by a circular RNA of BUB1B.The circBUB1B_544aa elevated in MM peripheral blood samples was closely associated with MM poor outcomes and played a synergistic effect with BUB1B on evoking CIN.In addition,MM cells could secrete circBUB1B_544aa and interfere the MM microenvironmental cells in the same manner as BUB1B full-length protein.Intriguingly,BUB1B siRNA,targeting the kinase catalytic center of both BUB1B and circBUB1B_544aa,significantly inhibited MM malignancy in vitro and in vivo.Collectively,BUB1B and circBUB1B_544aa are promising prognostic and therapeutic targets of MM.Xiaozhu Tang Mengjie guo Pinggang Ding Zhendong Deng Mengying Ke Yuxia Yuan Yanyan Zhou Zigen Lin Muxi Li Chunyan Gu Xiaosong Gu Ye Yang 2021Signal Transduction and Targeted Therapy2021,6,11:2
