| 1 | Advances in the development of molecular genetic tools for Mycobacterium tuberculosis显示文摘Mycobacterium tuberculosis, a Gram-positive bacterium of great clinical relevance, is a lethal pathogen owing to its complex physiological characteristics and development of drug resistance. Several molecular genetic tools have been developed in the past few decades to study this microorganism. These tools have been instrumental in understanding how M. tuberculosis became a successful pathogen. Advanced molecular genetic tools have played a significant role in exploring the complex pathways involved in M. tuberculosis pathogenesis. Here, we review various molecular genetic tools used in the study of M. tuberculosis. Further, we discuss the applications of clustered regularly interspaced short palindromic repeat interference(CRISPRi), a novel technology recently applied in M. tuberculosis research to study target gene functions. Finally, prospective outcomes of the applications of molecular techniques in the field of M. tuberculosis genetic research are also discussed. | Chiranjibi Chhotaray Yaoju Tan Julius Mugweru Md Mahmudul Islam H.M.Adnan Hameed Shuai Wang Zhili Lu Changwei Wang Xinjie Li Shouyong Tan Jianxiong Liu Tianyu Zhang | 2018 | Journal of Genetics and Genomics2018，45，6： | 2 |
| 2 | Effect of CO_2 on the structural variation of Na_2WO_4/Mn/SiO_2 catalyst for oxidative coupling of methane to ethylene显示文摘In this work,the influence of CO2 on the structural variation and catalytic performance of Na2WO4/Mn/Si O2 for oxidative coupling of methane to ethylene was investigated. The catalyst was prepared by impregnation method and characterized by XRD,Raman and XPS techniques. Appropriate amount of CO2 in the reactant gases enhanced the formation of surface tetrahedral Na2WO4 species and promoted the migration of O in MOx,Na,W from the catalyst bulk to surface,which were favorable for oxidative coupling of methane. When the molar ratio of CH4/O2/CO2 was 3/1/2,enriched surface tetrahedral Na2WO4 species and high surface concentration of O in MOx,Na,W were detected,and then high CH4 conversion of 33.1% and high C2H4 selectivity of 56.2% were obtained. With further increase of CO2 in the reagent gases,the content of active surface tetrahedral Na2WO4 species and surface concentration of O in MOx,Na,W decreased,while that of inactive species(Mn WO4 and Mn2O3) increased dramatically,leading to low CH4 conversion and low C2H4 selectivity. It could be speculated that Na2WO4 crystal was transformed into Mn WO4 crystal with excessive CO2 added under the reaction conditions. Pretreatment of Na2WO4/Mn/Si O2 catalyst by moderate amount of CO2 before OCM also promoted the formation of Na2WO4 species. | Jia Shi Lu Yao Changwei Hu | 2015 | Journal of Energy Chemistry2015，24，4： | 2 |

| 4 | Genome-Wide Linkage and Positional Association Analyses Identify Associations of Novel AFF3 and NTM Genes with Triglycerides:The GenSalt Study显示文摘We conducted a genome-wide linkage scan and positional association study to identify genes and variants influencing blood lipid levels among participants of the Genetic Epidemiology Network of Salt-Sensitivity(Gen Salt) study. The Gen Salt study was conducted among1906 participants from 633 Han Chinese families. Lipids were measured from overnight fasting blood samples using standard methods.Multipoint quantitative trait genome-wide linkage scans were performed on the high-density lipoprotein, low-density lipoprotein, and logtransformed triglyceride phenotypes. Using dense panels of single nucleotide polymorphisms(SNPs), single-marker and gene-based association analyses were conducted to follow-up on promising linkage signals. Additive associations between each SNP and lipid phenotypes were tested using mixed linear regression models. Gene-based analyses were performed by combining P-values from singlemarker analyses within each gene using the truncated product method(TPM). Significant associations were assessed for replication among777 Asian participants of the Multi-ethnic Study of Atherosclerosis(MESA). Bonferroni correction was used to adjust for multiple testing.In the Gen Salt study, suggestive linkage signals were identified at 2p11.2-2q12.1 [maximum multipoint LOD score(MML)=2.18 at2q11.2] and 11q24.3-11q25(MML=2.29 at 11q25) for the log-transformed triglyceride phenotype. Follow-up analyses of these two regions revealed gene-based associations of charged multivesicular body protein 3(CHMP3), ring finger protein 103(RNF103),AF4/FMR2 family, member 3(AFF3), and neurotrimin(NTM) with triglycerides(P=4 10 4, 1.00 10 5, 2.00 10 5, and1.00 10 7, respectively). Both the AFF3 and NTM triglyceride associations were replicated among MESA study participants(P=1.00 10 7and 8.00 10 5, respectively). Furthermore, NTM explained the linkage signal on chromosome 11. In conclusion, we identified novel genes associated with lipid phenotypes in linkage regions on chromosomes 2 and 11. | Changwei Li Lydia A.L.Bazzano Dabeeru C.Rao James E.Hixson Jiang He Dongfeng Gu Charles C.Gu Lawrence C.Shimmin Cashell E.Jaquish Karen Schwander De-Pei Liu Jianfeng Huang Fanghong Lu Jie Cao Shen Chong Xiangfeng Lu Tanika N.Kelly | 2015 | Journal of Genetics and Genomics2015，42，3： | 1 |

| 7 | Effect of methane co-feeding on the selectivity of ethylene produced from oxidative dehydrogenation of ethane with CO_2 over a Ni-La/SiO_2 catalyst显示文摘A Ni-La/SiO2 catalyst was prepared through the incipient wetness impregnation method and tested in the oxidative dehydrogenation of ethane (ODHE) with CO2 . The fresh and used catalysts were characterized by XRD and SEM techniques. The Ni-La/SiO2 catalyst exhibited catalytic activity for the oxidative dehydrogenation of ethane, but with low ethylene selectivity in the absence of methane. The selectivity to ethylene increased with increasing molar ratio of methane in the feed. The carbon deposited on the catalyst surface in the sole ODHE with CO2 was mainly inert carbon, while much more filamentous carbon was formed in the presence of methane. The filamentous carbon was easy to be removed by CO2 , which might play a role in improving the conversion of ethane to ethylene. The introduction of methane might affect the equilibrium of the CO2 reforming of ethane and the ODHE with CO2 . As a consequence, the synthesis gas produced from CO2 reforming of methane partly inhibited the reaction of ethane and promoted the ODHE with CO2 , thus increasing the selectivity of ethylene. | Xiaoxi Peng Jianqiang Zhu Lu Yao Changwei Hu | 2013 | Journal of Energy Chemistry2013，22，4： | 1 |
| 8 | Single-cell-resolution transcriptome map revealed novel genes involved in testicular germ cell progression and somatic cells specification in Chinese tongue sole with sex reversal显示文摘Female-to-male sex reversals(pseudomales)are common in lower vertebrates and have been found in natural populations,which is a concern under rapid changes in environmental conditions.Pseudomales can exhibit altered spermatogenesis.However,the regulatory mechanisms underlying pseudomale spermatogenesis remain unclear.Here,we characterized spermatogenesis in Chinese tongue sole(Cynoglossus semilaevis),a species with genetic and environmental sex determination,based on a highresolution single-cell RNA-seq atlas of cells derived from the testes of genotypic males and pseudomales.We identified five germ cell types and six somatic cell types and obtained a single-cell atlas of dynamic changes in gene expression during spermatogenesis in Chinese tongue sole,including alterations in pseudomales.We detected decreased levels of Ca^(2+)signaling pathway-related genes in spermatogonia,insufficient meiotic initiation in spermatocytes,and a malfunction of somatic niche cells in pseudomales.However,a cluster of CaSR genes and MAPK signaling factors were upregulated in undifferentiated spermatogonia of pseudomales.Additionally,we revealed that Z chromosome-specific genes,such as piwil2,dhx37,and ehmt1,were important for spermatogenesis.These results improve our understanding of reproduction after female-to-male sex-reversal and provide new insights into the adaptability of reproductive strategies in lower vertebrates. | Hong-Yan Wang Xiang Liu Jian-Yang Chen Yingyi Huang Yifang Lu Fujian Tan Qun Liu Mingming Yang Shuo Li Xianghui Zhang Yating Qin Wenxiu Ma Yingming Yang Liang Meng Kaiqiang Liu Qian Wang Guangyi Fan Rafael H.Nóbrega Shanshan Liu Francesc Piferrer Changwei Shao | 2023 | Science China(Life Sciences)2023，66，5： | 1 |

| 10 | Enhancement of T cell infiltration via tumor-targeted Th9 cell delivery improves the efficacy of antitumor immunotherapy of solid tumors显示文摘Insufficient infiltration of T cells severely compromises the antitumor efficacy of adoptive cell therapy(ACT)against solid tumors.Here,we present a facile immune cell surface engineering strategy aiming to substantially enhance the anti-tumor efficacy of Th9-mediated ACT by rapidly identifying tumor-specific binding ligands and improving the infiltration of infused cells into solid tumors.Non-genetic decoration of Th9 cells with tumor-targeting peptide screened from phage display not only allowed precise targeted ACT against highly heterogeneous solid tumors but also substantially enhanced infiltration of CD8+T cells,which led to improved antitumor outcomes.Mechanistically,infusion of Th9 cells modified with tumor-specific binding ligands facilitated the enhanced distribution of tumor-killing cells and remodeled the immunosuppressive microenvironment of solid tumors via IL-9 mediated immunomodulation.Overall,we presented a simple,cost-effective,and cell-friendly strategy to enhance the efficacy of ACT against solid tumors with the potential to complement the current ACT. | Tao Chen Yucheng Xue Shengdong Wang Jinwei Lu Hao Zhou Wenkan Zhang Zhiyi Zhou Binghao Li Yong Li Zenan Wang Changwei Li Yinwang Eloy Hangxiang Sun Yihang Shen Mohamed Diaty Diarra Chang Ge Xupeng Chai Haochen Mou Peng Lin Xiaohua Yu Zhaoming Ye | 2023 | Bioactive Materials2023，，5： | 0 |
