| 1 | Dysfunction of PLA2G6 and CYP2C44-associated network signals imminent carcinogenesis from chronic inflammation to hepatocellular carcinoma显示文摘很少长期的发炎怎么贡献 hepatocellular 癌(HCC ) 的前进被知道,特别癌症的开始。揭开从长期的发炎的批评转变到在网络水平的 HCC 和分子的机制,我们用我们的动态网络 biomarker (DNB ) 分析了土拨鼠肝炎 virus/c-myc 鼠标和匹配年龄的 wt-C57BL/6 鼠标的时间系列 proteomic 数据模型。DNB 分析显示在转基因的老鼠的出生以后的第 5 月是癌症开始的批评时期,就在批评转变前,它与临床的症状一致。同时,联系 DNB 的网络在批评转变前后显示出蛋白质表示和 coexpression 层次的激烈的倒置。DNB, PLA2G6 和 CYP2C44 的二个成员,与他们的联系差别一起表示了蛋白质,被发现导致 arachidonic 酸新陈代谢的机能障碍,进一步通过短暂受体潜力隧道的煽动性的调停人规定激活煽动性的回答,并且最后导致肝 detoxification 和恶意的转变的缺陷到癌症。作为一个 c-Myc 目标, PLA2G6 断然在表示与 c-Myc 相关,显示出从减少到在 carcinogenesis 期间增加的一个趋势,与在批评转变的最小的点或付小费给的点。相应 PLA2G6 和 c-Myc 的如此的趋势也在人的 hepatocarcinogenesis 期间被观察,与在高级 dysplastic 小瘤(就在 carcinogenesis 前的一个阶段) 的最小的点。我们的学习暗示 PLA2G6 可能在 hepatocarcinogenesis 期间作为象著名 c-Myc 一样的 oncogene 工作,当 PLA2G6 和 c-Myc 的 downregulation 能是显示逼近的 carcinogenesis 的一个警告信号时。 | Meiyi Li Chen Li Wei-Xin Liu Conghui Liu Jingru Cui Qingrun Li Hong Ni Yingcheng Yang Chaochao Wu Chunlei Chen Xing Zhen Tao Zeng Mujun zhao Lei Chen Jiarui Wu Rong Zeng Luonan Chen | 2017 | Journal of Molecular Cell Biology2017，9，6： | 12 |
| 2 | Expression of reconstructive hF Ⅷ in the hrDNA by using hrDNA targeting vector显示文摘Our lab has constructed a new nonviral vec-tor—hrDNA targeting vector(pHrneo). pHrneo is a human derived vector that can target gene into human ribosomal DNA(hrDNA) locus. In this study, we inserted expression cassette of reconstructive hF Ⅷ (hFVIII-BDDAK39) to pHrneo to construct targeting vector: pHrneo-BDDAK39. Through electroporation of pHrneo-BDDAK39 into HT1080 cells, we identified the homologous recombinants by PCR and Southen blotting, and tested the expression of hFVIII- BDDAK39 in the hrDNA locus. The hFⅧ-BDDAK39 was successfully targeted into hrDNA locus of HT-1080 by pHrneo-BDDAK39, and the efficiency of site-specific inte-gration was 2.0×10?5. hFⅧ-BDDAK39 in hrDNA locus of HT-1080 is found to be able to express efficiently (32±5 ng·106 cells?1·24 h?1). Targeting vector pHrneo-BDDAK39 can find use in gene therapy for hemophilia. | LIU Xionghao LIU Mujun SHE Hua WEN Lu XUE Zhigang LIANG Desheng CAI Fang PAN Qian LONG Zhigao WU Lingqian DAI Heping XIA Kun XlA Jiahui | 2005 | Chinese Science Bulletin2005，50，19： | 5 |
| 3 | Sorl1 knockout inhibits expression of brain-derived neurotrophic factor:involvement in the development of late-onset Alzheimer's disease显示文摘Sortilin-related receptor 1(SORL1)is a critical gene associated with late-onset Alzheimer’s disease.SORL1 contributes to the development and progression of this neurodegenerative condition by affecting the transport and metabolism of intracellularβ-amyloid precursor protein.To better understand the underlying mechanisms of SORL1 in the pathogenesis of late-onset Alzheimer s disease,in this study,we established a mouse model of SorI1 gene knockout using cluste red regularly inters paced short palindro mic repeats-associated protein 9 technology.We found that Sorl1-knocko ut mice displayed deficits in learning and memory.Furthermore,the expression of brain-derived neurotrophic factor was significantly downregulated in the hippocampus and co rtex,and amyloidβ-protein deposits were observed in the brains of 5orl1-knockout mice.In vitro,hippocampal neuronal cell synapses from homozygous Sorl1-knockout mice were impaired.The expression of synaptic proteins,including Drebrin and NR2B,was significantly reduced,and also their colocalization.Additionally,by knocking out the Sorl1 gene in N2a cells,we found that expression of the N-methyl-D-aspartate receptor,NR2B,and cyclic adenosine monophosphate-response element binding protein was also inhibited.These findings suggest that SORL1 participates in the pathogenesis of late-onset Alzheimer s disease by regulating the N-methyl-D-aspartate receptor NR2B/cyclic adenosine monophosphate-response element binding protein signaling axis. | Mingri Zhao Xun Chen Jiangfeng Liu Yanjin Feng Chen Wang Ting Xu Wanxi Liu Xionghao Liu Mujun Liu Deren Hou | 2024 | Neural Regeneration Research2024，19，7： | 2 |

| 5 | IL-24 armored CAR19-T cells show enhanced antitumor activity and persistence显示文摘Dear Editor,Nowadays,two autologous CAR19-T drugs,Tisagenlecleucel(Kymriah^(TM))and axicabtagene ciloleucel(Yescarta^(TM)),have been approved for the treatment of B cell leukemia and lymphoma and achieved unprecedented successes.However,about 10-20%of B-ALL patients receiving CAR19-T drugs didn't achieve complete remission(CR),while 30~50%of patients achieved CR would relapse mainly within 1 year.Moreover,the high CR rate of CAR19-T therapy for B-ALL can't be recaptured in other B-NHLs,'such as Burkitt's lymphoma(BL).Therefore,there is an urgent need to improve the therapeutic efficacy of CAR19-T cells.3. | Qian Hu Yuxuan Zhang Peiyun Wang Miaojin Zhou Zhiqing Hu Cong Liu Mujun Liu Lingqian Wu Xionghao Liu Desheng Liang | 2021 | Signal Transduction and Targeted Therapy2021，6，2： | 0 |
| 6 | The MORC2 p.S87L mutation reduces proliferation of pluripotent stem cells derived from a patient with the spinal muscular atrophy-like phenotype by inhibiting proliferation-related signaling pathways显示文摘Mutations in the microrchidia CW-type zinc finger protein 2(MORC2)gene are the causative agent of Charcot-Marie-Tooth disease type 2Z(CMT2Z),and the hotspot mutation p.S87L is associated with a more seve re spinal muscular atrophy-like clinical phenotype.The aims of this study were to determine the mechanism of the severe phenotype caused by the MORC2 p.S87L mutation and to explore potential treatment strategies.Epithelial cells were isolated from urine samples from a spinal muscular atrophy(SMA)-like patient[MORC2 p.S87L),a CMT2Z patient[MORC2 p.Q400R),and a healthy control and induced to generate pluripotent stem cells,which were then differentiated into motor neuron precursor cells.Next-generation RNA sequencing followed by KEGG pathway enrichment analysis revealed that differentially expressed genes involved in the PI3K/Akt and MAP K/ERK signaling pathways were enriched in the p.S87L SMA-like patient group and were significantly downregulated in induced pluripotent stem cells.Reduced proliferation was observed in the induced pluripotent stem cells and motor neuron precursor cells derived from the p.S87L SMA-like patient group compared with the CMT2Z patient group and the healthy control.G0/G1 phase cell cycle arrest was observed in induced pluripotent stem cells derived from the p.S87L SMA-like patient.MORC2 p.S87Lspecific antisense oligonucleotides(p.S87L-ASO-targeting)showed significant efficacy in improving cell prolife ration and activating the PI3K/Akt and MAP K/ERK pathways in induced pluripotent stem cells.Howeve r,p.S87L-ASO-ta rgeting did not rescue prolife ration of motor neuron precursor cells.These findings suggest that downregulation of the PI3K/Akt and MAP K/ERK signaling pathways leading to reduced cell proliferation and G0/G1 phase cell cycle arrest in induced pluripotent stem cells might be the underlying mechanism of the severe p.S87L SMA-like phenotype.p.S87L-ASO-targeting treatment can alleviate disordered cell proliferation in the early stage of pluripotent stem cell induction. | Sen Zeng Honglan Yang Binghao Wang Yongzhi Xie Ke Xu Lei Liu Wanqian Cao Xionghao Liu Beisha Tang Mujun Liu Ruxu Zhang | 2024 | Neural Regeneration Research2024，19，1： | 0 |
| 7 | CTGNet: Automatic Analysis of Fetal Heart Rate from Cardiotocograph Using Artificial Intelligence显示文摘Objective:This study investigates the efficacy of analyzing fetal heart rate(FHR)signals based on Artificial Intelligence to obtain a baseline calculation and identify accelerations/decelerations in the FHR through electronic fetal monitoring during labor.Methods:A total of 43,888 cardiotocograph(CTG)records of female patients in labor from January 2012 to December 2020 were collected from the NanFang Hospital of Southern Medical University.After filtering the data,2341 FHR records were used for the study.The ObVue fetal monitoring system,manufactured by Lian-Med Technology Co.Ltd.,was used to monitor the FHR signals for these pregnant women from the beginning of the first stage of labor to the end of delivery.Two obstetric experts together annotated the FHR signals in the system to determine the baseline as well as accelerations/decelerations of the FHR.Our cardiotocograph network(CTGNet)as well as traditional methods were then used to automatically analyze the baseline and acceleration/deceleration of the FHR signals.The results of calculations were compared with the annotations provided by the obstetric experts,and ten-fold cross-validation was applied to evaluate them.The root-mean-square difference(RMSD)between the baselines,acceleration F-measure(Acc.F-measure),deceleration F-measure(Dec.F-measure),coefficient of synthetic inconsistency(SI)and the morphological analysis discordance index(MADI)were used as evaluation metrics.The data were analyzed by using a pairedt-test.Results:The proposed CTGNet was superior to the best traditional method,proposed by Mantel,in terms of the RMSD.BL(1.7935±0.8099vs.2.0293±0.9267,t=-3.55,P=0.004),Acc.F-measure(86.8562±10.9422vs.72.2367±14.2096,t=12.43,P<0.001),Dec.F-measure(72.1038±33.2592vs.58.5040±38.0276,t=4.10,P<0.001),SI(34.8277±20.9595vs.54.8049±25.0265,t=-9.39,P<0.001),and MADI(3.1741±1.9901vs.3.7289±2.7253,t=-2.74,P=0.012).The proposed CTGNet thus had significant advantages over the best traditional method on all evaluation metrics.Conclusion:The proposed Artificial Intelligence-based method CTGNet delivers good performance in terms of the automatic analysis of FHR based on cardiotocograph data.It promises to be a key component of smart obstetrics systems of the future. | Mei Zhong Hao Yi Fan Lai Mujun Liu Rongdan Zeng Xue Kang Yahui Xiao Jingbo Rong Huijin Wang Jieyun Bai Yaosheng Lu | 2022 | Maternal-Fetal Medicine2022，4，2： | 0 |
