| 1 | Computer Simulation of Thermal-Mechanical Processing显示文摘Supported by the high-speed SGI engineering workstation and the general MARCTM software, a system is developed to simulate the hot deformation process and the cooling process after deformation in the forging of Cr12 steel on the basis of elastic-plastic FEM techniques with coupled thermal-mechanical-microstructural alteration. In this system, a mathematical model, obtained by plentiful physical simulation experiments on Gleeble 1500 thermomechanical simulator, is introduced to describe the changes in microstructure and properties of steels. This system is proved to be reliable to simulate the thermal field and stress field as well as the microstructure of Cr12 steel during the forging process. It can also be used to optimize and control the forging process. | Ruiheng Wu, Zigang Li, Hongbing Chang, T. Y.

| 3 | Overexpression of Sirt6 ameliorates sleep deprivation induced-cognitive impairment by modulating glutamatergic neuron function显示文摘Sleep benefits the restoration of energy metabolism and thereby suppo rts neuronal plasticity and cognitive behaviors.Sirt6 is a NAD+-dependent protein deacetylase that has been recognized as an essential regulator of energy metabolism because it modulates various transcriptional regulators and metabolic enzymes.The aim of this study was to investigate the influence of Sirt6 on cerebral function after chronic sleep deprivation(CSD).We assigned C57BL/6J mice to control or two CSD groups and subjected them to AAV2/9-CMV-EGFP or AAV2/9-CMV-Sirt6-EGFP infection in the prelimbic cortex(PrL).We then assessed cerebral functional connectivity(FC) using resting-state functional MRI,neuron/astrocyte metabolism using a metabolic kinetics analysis;dendritic spine densities using sparse-labeling;and miniature excitato ry postsynaptic currents(mEPSCs) and action potential(AP) firing rates using whole-cell patchclamp recordings.In addition,we evaluated cognition via a comprehensive set of behavioral tests.Compared with controls,Sirt6 was significantly decreased(P<0.05) in the PrL after CSD,accompanied by cognitive deficits and decreased FC between the PrL and accumbens nucleus,piriform cortex,motor co rtex,somatosensory co rtex,olfactory tubercle,insular cortex,and cerebellum.Sirt6 ove rexpression reve rsed CSD-induced cognitive impairment and reduced FC.Our analysis of metabolic kinetics using [1-13C] glucose and [2-13C] acetate showed that CSD reduced neuronal Glu4and GABA2synthesis,which could be fully restored via forced Sirt6 expression.Furthermore,Sirt6 ove rexpression reversed CSD-induced decreases in AP firing rates as well as the frequency and amplitude of mEPSCs in PrL pyramidal neurons.These data indicate that Sirt6 can improve cognitive impairment after CSD by regulating the PrL-associated FC network,neuronal glucose metabolism,and glutamatergic neurotransmission.Thus,Sirt6 activation may have potential as a novel strategy for treating sleep disorder-related diseases. | Jinpiao Zhu Chang Chen Zhen Li Xiaodong Liu Jingang He Ziyue Zhao Mengying He Binbin Nie Zili Liu Yingying Chen Kuanpin Su Xiang Li Juxiang Chen Hongbing Xiang Fuqiang Xu Kangguang Lin Zongze Zhang Jie Wang | 2023 | Neural Regeneration Research2023，18，11： | 1 |

| 14 | Gene amplification-driven RNA methyltransferase KIAA1429 promotes tumorigenesis by regulating BTG2 via m6A-YTHDF2-dependent in lung adenocarcinoma显示文摘Background:Epigenetic alterations have been shown to contribute immensely to human carcinogenesis.Dynamic and reversible N6-methyladenosine(m6A)RNA modification regulates gene expression and cell fate.However,the reasons for activation of KIAA1429(also known as VIRMA,an RNA methyltransferase)and its underlying mechanism in lung adenocarcinoma(LUAD)remain largely unexplored.In this study,we aimed to clarify the oncogenic role of KIAA1429 in the tumorigenesis of LUAD.Methods:Whole-genome sequencing and transcriptome sequencing of LUAD data were used to analyze the gene amplification of RNA methyltransferase.The in vitro and in vivo functions of KIAA1429 were investigated.Transcriptome sequencing,methylated RNA immunoprecipitation sequencing(MeRIP-seq),m6A dot blot assays and RNA immunoprecipitation(RIP)were performed to confirm the modified gene mediated by KIAA1429.RNA stability assays were used to detect the half-life of the target gene.Results:Copy number amplification drove higher expression of KIAA1429 in LUAD,whichwas correlatedwith poor overall survival.Manipulating the expression of KIAA1429 could regulate the proliferation and metastasis of LUAD.Mechanistically,the target genes of KIAA1429-mediated m6A modification were confirmed by transcriptome sequencing and MeRIP-seq assays.We also revealed that KIAA1429 could regulate BTG2 expression in an m6A-dependent manner.Knockdown of KIAA1429 significantly decreased the m6A levels of BTG2 mRNA,leading to enhanced YTH m6A RNA binding protein 2(YTHDF2,the m6A“reader”)-dependent BTG2 mRNA stability and promoted the expression of BTG2;thus,participating in the tumorigenesis of LUAD.Conclusions:Our data revealed the activation mechanism and important role of KIAA1429 in LUAD tumorigenesis,which may provide a novel view on the targeted molecular therapy of LUAD. | Chang Zhang Qi Sun Xu Zhang Na Qin Zhening Pu Yayun Gu Caiwang Yan Meng Zhu Juncheng Dai ChengWang Ni Li Guangfu Jin Hongxia Ma Zhibin Hu Erbao Zhang Fengwei Tan Hongbing Shen | 2022 | Cancer Communications2022，42，7： | 1 |

| 16 | Influence of meteorological factors on open biomass burning at a background site in Northeast China显示文摘Biomass burning(BB)is a very important emission source that significantly adversely impacts regional air quality.BB produces a large number of primary organic aerosol(POA)and black carbon(BC).Besides,BB also provides many precursors for secondary organic aerosol(SOA)generation.In this work,the ratio of levoglucosan(LG)to organic carbon(OC)and the fire hotspots map was used to identify the open biomass burning(OBB)events,which occurred in two representative episodes,October 13 to November 30,2020,and April1 to April 30,2021.The ratio of organic aerosol(OA)to reconstructed PM_(2.5)concentration(PM_(2.5)^(*))increased with the increase of LG/OC.When LG/OC ratio is higher than 0.03,the highest OA/PM_(2.5)^(*)ratio can reach 80%,which means the contribution of OBB to OA is crucial.According to the ratio of LG to K^(+),LG to mannosan(MN)and the regional characteristics of Longfengshan,it can be determined that the crop residuals are the main fuel.The occurrence of OBB coincides with farmers’preferred choices,i.e.,burning biomass in“bright weather”.The“bright weather”refers to the meteorological conditions with high temperature,low humidity,and without rain.Meteorological factors indirectly affect regional biomass combustion pollution by influencing farmers’active choices. | Yulong Wang Linlin Liang Wanyun Xu Chang Liu Hongbing Cheng Yusi Liu Gen Zhang Xiaobin Xu Dajiang Yu Peng Wang Qingli Song Jiumeng Liu Yuan Cheng | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
| 17 | A causal variant rs3769823 in 2q33.1 involved in apoptosis pathway leading to a decreased risk of non-small cell lung cancer显示文摘Objective:Although our previous genome-wide association study(GWAS)has identified chromosome 2q33.1 as a susceptibility locus for non-small cell lung cancer(NSCLC),the causal variants remain unclear.The aims of this study were to identify the causal variants in 2q33.1 and to explore their biological functions in NSCLC.Methods:CCK-8,colony formation,EdU incorporation,Transwell,and quantitative real-time polymerase chain reaction assays were applied to examine variant function.The tumor xenograft model was used to examine variant function in vivo.Caspase-8 activity assays,flow cytometry analysis,and co-immunoprecipitation assays were used to explore the molecular mechanism.Results:The missense variant rs3769823(A>G),which caused the substitution of lysine with arginine at amino acid 14 in caspase-8(caspase-8K14R),was identified as a potential causal candidate in 2q33.1.Compared with the wild type caspase-8(caspase8WT)group,the caspase-8K14R group had higher expression of caspase-8 and cleaved caspase-8.Caspase-8K14R inhibited the proliferation and metastasis of human lung cancer cell lines in vitro.Moreover,caspase-8K14R repressed lung cancer cell growth in vivo.Mechanistically,caspase-8K14R was more sensitive than caspase-8WT to tumor necrosis factor-related apoptosis-inducing ligand(TRAIL)-mediated apoptosis and showed higher binding of caspase-8 and FADD.Conclusions:These results suggested that rs3769823 is the causal variant in chromosome 2q33.1 and is involved in an apoptosis pathway,leading to a decreased risk of NSCLC. | Xu Zhang Na Qin Jingyi Fan Chang Zhang Qi Sun Yayun Gu Meng Zhu Erbao Zhang Juncheng Dai Guangfu Jin Hongxia Ma Zhibin Hu Hongbing Shen | 2022 | Cancer Biology & Medicine2022，19，9： | 0 |
