| 1 | Correction of a genetic disease by CRISPR-Cas9-mediated gene editing in mouse spermatogonial stem cells显示文摘Spermatogonial 干细胞(SSC ) 能在移植以后生产众多的男配偶子进接受者睾丸,介绍为基因治疗和修改基因的动物的连续生产的一条珍贵途径。然而, SSC 的成功的基因操作被限制了,部分由于复杂性和当前可得到的基因编辑技术的低效率。这里,我们证明有效基因修正能用 CRISPR-Cas9 系统被介绍进 SSC。我们使用了 CRISPR-Cas9 系统变异在 SCC 的 EGFP transgene 或内长的 Crygc 基因。变异的 SSC 在移植以后经历了精子发生进不肥沃的老鼠睾丸的生精的小管。圆 spermatids 被产生并且在进成熟卵母细胞的注射以后,支持了显示相应变异的显型的异质接合的后代的生产。而且,在 Crygc 的一个引起疾病的变化(在 SSC 先存在的 Crygc −/−) 能乐意地到加入的 CRISPR-Cas9-induced nonhomologous 结束(NHEJ ) 或指导相同的修理(HDR ) 被修理,导致没有是的离开目标修正的证据带改正的基因的 SSC 线由整个染色体的定序出现。用从这些线产生的圆 spermatids 的授精在 100% 的效率与改正的显型产生了后代。我们的结果表明有效基因由 CRISPR-Cas9 系统在老鼠 SSC 编辑,并且提供在 SSC 经由基因修正治好基因疾病的原则的证明。 | Yuxuan Wu Hai Zhou Xiaoying Fan Ying Zhang Man Zhang Yinghua Wang Zhenfei Xie Meizhu Bai Qi Yin Dan Liang Wei Tang Jiaoyang Liao Chikai Zhou Wujuan Liu Ping Zhu Hongshan Guo Hong Pan Chunlian Wu Huijuan Shi Ligang Wu Fuchou Tang Jinsong Li | 2015 | Cell Research2015，25，1： | 37 |

| 4 | Polyvalent mRNA vaccination elicited potent immune response to monkeypox virus surface antigens显示文摘Dear Editor,The global monkeypox(Mpox)outbreak leads to a surge in demand for vaccine.The Mpox vaccine in short supply is JYNNEOS(modified vaccinia ankara,MVA)due to less side effects,while ACAM2000 supply is abundant because of the strategic stockpile in U.s.1 The ACAM2000 replaced the first-generation smallpox vaccine Dryvax that has a questionable safety profile.However,the ACAM2000 is associated with high rate of myocarditis and pericarditis,and can cause severe illness in immunocompromised patients,foreshadowing the need to update the strategic stockpile. | Zhenhao Fang Valter S.Monteiro Paul A.Renauer Xingbo Shang Kazushi Suzuki Xinyu Ling Meizhu Bai Yan Xiang Andre Levchenko Carmen J.Booth Carolina Lucas Sidi Chen | 2023 | Cell Research2023，33，5： | 1 |
| 5 | Spermatogenic Cell-Specific Gene Mutation in Mice via CRISPR-Cas9显示文摘Tissue-specific knockout technology enables the analysis of the gene function in specific tissues in adult mammals.However,conventional strategy for producing tissue-specific knockout mice is a time- and labor-consuming process,restricting rapid study of the gene function in vivo.CRISPR-Cas9 system from bacteria is a simple and efficient gene-editing technique,which has enabled rapid generation of gene knockout lines in mouse by direct injection of CRISPR-Cas9 into zygotes.Here,we demonstrate CRISPR-Cas9-mediated spermatogenic cell-specific disruption of Scp3 gene in testes in one step.We first generated transgenic mice by pronuclear injection of a plasmid containing Hspa2 promoter driving Cas9 expression and showed Cas9 specific expression in spermatogenic cells.We then produced transgenic mice carrying Hspa2 promoter driven Cas9 and constitutive expressed sgRNA targeting Scp3 gene.Male founders were infertile due to developmental arrest of spermatogenic cells while female founders could produce progeny normally.Consistently,male progeny from female founders were infertile and females could transmit the transgenes to the next generation.Our study establishes a CRISPR-Cas9-based one-step strategy to analyze the gene function in adult tissues by a temporal-spatial pattern. | Meizhu Bai Dan Liang Yinghua Wang Qing Li Yuxuan Wu Jinsong Li | 2016 | Journal of Genetics and Genomics2016，43，5： | 1 |
| 6 | Function and Cryo-EM structures of broadly potent bispecific antibodies against multiple SARS-CoV-2 Omicron sublineages显示文摘Dear Editor,SARS-CoV-2 rapidly evolves during the pandemic1 with many variants of concern(VoCs)lineages(Supplementary Fig.S1a).Omicron(B.1.1.529)and its sub-lineages led to multiple infection waves globally.2 Omicron subvariants harbored a high number of mutations,especially in the spike(S)glycoprotein,and clustered in the receptor-binding domain(RBD)(Supplementary Fig.S1b,c;Supplemental Discussion).These subvariants drastically decrease the efficacy of current vaccinations and monoclonal antibody therapies. | Ping Ren Yingxia Hu Lei Peng Luojia Yang Kazushi Suzuki Zhenhao Fang Meizhu Bai Liqun Zhou Yanzhi Feng Yongji Zou Yong Xiong Sidi Chen | 2023 | Signal Transduction and Targeted Therapy2023，8，8： | 0 |
| 7 | Gonadal mosaicism mediated female-biased gender control in mice显示文摘Dear Editor, In nature or during artificial breeding,evolutionary interven-tion or desirable trait selection could be achieved by means of gender control in an organism.Previously reported approaches including sex-sorted semen and genetic manipulation of a certain gene(Holden and Butler,2018;Yosef et al.,2019).In mice,a recent study demonstrated a genetic system for biasing sex ratio through crossing two genetically engineered mouse lines(Yosef et al.,2019).The maternal line encodes functional Cas9 protein on an auto-somal chromosome,whereas the paternal encodes guide RNAs on Y chromosome targeting vital genes.After fertil-ization,males carrying both Cas9 and guide RNAs were self-destructed,resulting in a female biased sex ratio.However,the litter size is proximate half of normal size since half of the progeny are eliminated.Moreover,a reproductive reservoir of males and females must be maintained for crossing.Here,we established a mouse line carrying Hspa2 promoted Cas9 and constitutively expressed sgRNA targeting repetitive sequences on Y chromosome.In those mice,spermatogenic cells carrying Y chromosome were eliminated during sper-matogenesis,resulting in female biased sex ratio in proge-nies whereas the total number was unaffected. | Meizhu Bai Dan Liang Yan Cheng Guolong Liu Qiudao Wang Jinsong Li Yuxuan Wu | 2022 | Protein & Cell2022，13，11： | 0 |
