| 2 | Generation and characterization of stable pig pregastrulation epiblast stem cell lines显示文摘Pig epiblast-derived pluripotent stem cells are considered to have great potential and broad prospects for human therapeutic model developme nt and livestock breeding.Despite on going attempts since the 1990s,no stably defined pig epiblast-derived stem cell line has bee n established.Here,guided by in sights from a large-scale sin gle-cell tran scriptome an alysis of pig embryos from embryonic day(E)0 to E14,specifically,the tracing of pluripotency changes during epiblast development,we developed an in vitro culture medium for establishing and maintaining stable pluripotent stem cell lines from pig E10 pregastrulation epiblasts(pgEpiSCs).Enabled by chemical inhibition of WNT-related signaling in combination with growth factors in the FGF/ERK,JAK/STAT3,and Activin/Nodal pathways,pgEpiSCs maintain their pluripotency transcriptome features,similar to those of E10 epiblast cells,and normal karyotypes after more than 240 passages and have the potential to differentiate into three germ layers.Strikingly,ultradeep in situ Hi-C analysis revealed functional impacts of chromatin 3D-spatial associations on the transcriptional regulation of pluripote ncy marker genes in pgEpiSCs.I n practice,we con firmed that pgEpiSCs readily tolerate at least three rounds of successive gene editi ng and gene rated cloned gen e-edited live piglets.Our findings deliver on the long-a nticipated promise of pig pluripote nt stem cells and open new avenues for biological research,animal husbandry,and regenerative biomedicine. | Minglei Zhi Jinying Zhang Qianzi Tang Dawei Yu Shuai Gao Dengfeng Gao Pengliang Liu Jianxiong Guo Tang Hai Jie Gao Suying Cao Zimo Zhao Chongyang Li Xiaogang Weng Mengnan He Tianzhi Chen Yingjie Wang Keren Long Deling Jiao Guanglei Li Jiaman Zhang Yan Liu Yu Lin Daxin Pang Qianqian Zhu Naixin Chen Jingjing Huang Xinze Chen Yixuan Yao Jingcang Yang Zicong Xie Xianya Huang Mengxin Liu Ran Zhang Qiuyan Li Yiliang Miao Jianhui Tian Xingxu Huang Hongsheng Ouyang Bofeng Liu Wei Xie Qi Zhou Zhonghua Liu Caihong Zheng Mingzhou Li Jianyong Han | 2022 | Cell Research2022，32，4： | 3 |

| 4 | Analysis of molecular variation in porcine reproductive and respiratory syndrome virus in China between 2007 and 2012显示文摘In the present study, 89 porcine reproductive and respiratory syndrome virus(PRRSV) isolates in China during 2007 to 2012 were randomly selected from the GenBank genetic sequence database. Evolutionary characteristics of these isolates were analyzed based on the sequences of non-struc-tural protein 2(Nsp2) and glycoprotein 5(GP5). The genetic variations of the isolates were also compared with six representative strains. The results showed that a high degree of genetic diversity exists among the PRRSV population in China. Highly pathogenic PRRSV isolates, with a discon-tinuous deletion of a 30 amino acid residue in the Nsp2 region, remained the most dominant virus throughout 2007–2012 in China. Owing to the extensive use of representative vaccine strains, natu-ral recombination events occurred between strains. Three isolates – HH08, DY, and YN-2011 – were more closely related to vaccine strains than the other isolates. Both YN-2011 and DY were the evolu-tionary products of recombination events between strains SP and CH-1R. The results of the present study provide useful information for the epidemiology of PRRSV as well as for vaccine development. | Yuhang Cao Hongsheng Ouyang Mingjun Zhang Fuwang Chen Xin Yang Daxing Pang Linzhu Ren | 2014 | Virologica Sinica2014，29，3： | 2 |
| 5 | Production of transgenic pigs over-expressing theantiviral gene Mx1显示文摘The myxovirus resistance gene (Mx1) has a broad spectrum of antiviral activities. It is therefore an interestingcandidate gene to improve disease resistance in farm animals. In this study, we report the use of somatic cellnuclear transfer (SCNT) to produce transgenic pigs over-expressing the Mx1 gene. These transgenic pigs expressapproximately 15–25 times more Mx1 mRNA than non-transgenic pigs, and the protein level of Mx1 was alsomarkedly enhanced. We challenged fibroblast cells isolated from the ear skin of transgenic and control pigs withinfluenza A virus and classical swine fever virus (CFSV). Indirect immunofluorescence assay (IFA) revealed a profounddecrease of influenza A proliferation in Mx1 transgenic cells. Growth kinetics showed an approximately 10-foldreduction of viral copies in the transgenic cells compared to non-transgenic controls. Additionally, we found thatthe Mx1 transgenic cells were more resistant to CSFV infection in comparison to non-transgenic cells. These resultsdemonstrate that the Mx1 transgene can protect against viral infection in cells of transgenic pigs and indicate thatthe Mx1 transgene can be harnessed to develop disease-resistant pigs. | Quanmei Yan Huaqiang Yang Dongshan Yang Bentian Zhao Zhen Ouyang Zhaoming Liu Nana Fan Hongsheng Ouyang Weiwang Gu Liangxue Lai | 2014 | Cell Regeneration2014，3，1： | 2 |

| 9 | Scriptaid affects histone acetylation and the expression of development-related genes at different stages of porcine somatic cell nuclear transfer embryo during early development显示文摘Although the somatic cell nuclear transfer(SCNT) technique has been used extensively for cloning and generating transgenic pigs,the cloning efficiency is still very low.It has been proposed that the low efficiency of this technique is the result of incomplete epigenetic reprogramming and abnormal gene expression during early embryonic development.In this study,we investigate the effect of Scriptaid,a low-toxicity histone deacetylase inhibitor,on the developmental competence of porcine SCNT embryos.We found that treating SCNT embryos with 500 nmol/L Scriptaid for 15 h after activation significantly enhanced the blastocyst formation rate(27.7%) compared with the untreated group(control)(12.2%,P<0.05).Using an immunofluorescence technique to measure the average fluorescence intensity,we also found that treating SCNT embryos with Scriptaid increased the level of histone acetylation on histone H3 at lysine 14(acH3K14).Furthermore,treating embryos with Scriptaid increased the expression level of three genes that play important roles during embryonic development(Oct4,Klf4 at the blastocyst stage and Nanog at the 4-cell stage).Moreover,the expression level of the apoptosis-related gene Caspase-3 was significantly lower in the Scriptaid-treated SCNT embryos compared with the control SCNT embryos at the 4-cell and blastocyst stages.In conclusion,these results indicate that Scriptaid treatment improves the development and nuclear reprogramming of porcine SCNT embryos. | ZHOU Yan HUANG YongYe XIE WanHua SONG Qi JI Yuan ZHANG YanPing OUYANG HongSheng LAI LiangXue PANG DaXin TANG XiaoChun | 2013 | Chinese Science Bulletin2013，58，18： | 1 |

| 13 | Comparison of Five Endogenous Reference Genes for Specific PCR Detection and Quantification of Rice显示文摘Endogenous reference genes (ERGs) provide vital information regarding genetically modified organisms (GMOs). The successful detection of ERGs can identity GMOs and the source of genes, verify stability and reliability of the detection system, and calculate the level of genetically modified (GM) ingredients in mixtures. The reported ERGs in rice include sucrose-phosphate synthase (SPS), phospholipase D (PLD), RBE4 and rice root-specific GOS9 genes. Based on the characteristics of ERGs, a new ERG gene, phosphoenolpyruvate carboxylase (PEPC), was selected, and further compared with the four existing genes. A total of 18 rice varieties and 29 non-rice crops were used to verify the interspecies specificity, intraspecies consistency, sensitivity, stability and reliability of these five ERGs using qualitative and quantitative PCR. Qualitative detection indicated that SPS and PEPC displayed sufficient specificity, and the detection sensitivity was 0.05% and 0.005%, respectively. Although the specificity of both RBE4 and GOS9 were adequate, the amplicons were small and easily confused with primer dimers. Non-specific amplification of the PLD gene was present in maize and potato. Real-time quantitative PCR detection indicated that PLD, SPS and PEPC displayed good specificity, with R2 of the standard curve greater than 0.98, while the amplification efficiency ranged between 90% and 110%. Both the detection sensitivities of PLD and PEPC were five copies and that of SPS was ten copies. RBE4 showed typical amplification in maize, beet and Arabidopsis, while GOS9 was found in maize, tobacco and oats. PEPC exhibited excellent detection sensitivity and species specificity, which made it a potentially useful application in GM-rice supervision and administration. Additionally, SPS and PLD are also suitable for GM-rice detection. This study effectively established a foundation for GMO detection, which not only provides vital technical support for GMO identification, but also is of great significance for enhancing the comparability of detection results, and the standardization of ERG testing in GM-rice. | ZHANG Xiujie JIN Wujun XU Wentao LI Xiaying SHANG Ying LI Sha OUYANG Hongsheng | 2019 | Rice science2019，26，4： | 0 |
