| 1 | Biallelic mutations in CDC20 cause female infertility characterized by abnormalities in oocyte maturation and early embryonic development显示文摘Dear Editor,Previously,the Mendelian phe no types in huma n oocyte maturation arrest,fertilization failure and early embryonic arrest,are largely underestimated.In recent years,'missing'Men delian phe no types and genes in these processes are beginning to be uncovered by us and others(Huang et al.,2014;Alazami et al..2015;Feng et al.,2016;Xu et al.,2016;Chen et al.,2017;Sang et al.,2019).However,the genetic basis for majority of patients resulting from abnormalities in these phe no types remains to be elucidated. | Lin Zhao Songguo Xue Zhongyuan Yao Juanzi Shi Biaobang Chen Ling Wu Lihua Sun Yao Xu Zheng Yan Bin Li Xiaoyan Mao Jing Fu Zhihua Zhang Jian Mu Wenjing Wang Jing Du Shuai Liu Jie Dong Weijie Wang Qiaoli Li Lin He Li Jin Xiaozhen Liang Yanping Kuang Xiaoxi Sun Lei Wang Qing Sang | 2020 | Protein & Cell2020，11，12： | 10 |
| 2 | Curcumin’s prevention of inflammation-driven early gastric cancer and its molecular mechanism显示文摘Worldwide,gastric cancer is the second leading cause of cancer deaths and the fifth most common malignant tumor.Gastric cancer is believed to be caused by a variety of factors,such as genetics,epigenetics,and environmental influences.Among the pathogenic factors,inflammation has been considered as one of the main risk factors for gastric cancer.There are currently limited ways to prevent gastric cancer.Although the combined application of aspirin and non-steroidal anti-inflammatory drugs can reduce the risk,it has great side effects and can easily cause gastric perforation or gastric bleeding.Therefore,an alternative plan is urgently needed.Curcumin is the yellow pigment in the rhizome of the plant turmeric.Current studies have found that curcumin has a protective effect on gastric mucosal damage caused by non-steroidal anti-inflammatory drugs,gastric mucosal damage in rats,and gastric mucosal damage caused by stress bleeding and Helicobacter pylori infection.Curcumin shows significant antiinflammatory and anti-cancer activities by regulating DNA methylation,histone modification,nuclear factor erythrocyte 2 related factor 2 and other related signal pathways.In this article,the latest evidence of curcumin for epigenetic changes in gastric cancer and its potential contribution to gastric cancer were discussed. | Wensen Zhang Na Cui Jin Ye Bingyou Yang Yanping Sun Haixue Kuang | 2022 | Chinese Herbal Medicines2022，14，2： | 3 |
| 3 | YTHDF2 is essential for spermatogenesis and fertility by mediating a wave of transcriptional transition in spermatogenic cells显示文摘The dynamic and reversible regulation roles of m^(6)A modification and the characterization of m^(6)A readers have provided new insights into spermatogenesis at the post-transcriptional level.YTHDF2,as an m^(6)A reader,has been reported to mediate the m^(6)A-containing transcript decay during the mouse oocyte maturation,embryonic stem cell differentiation,neural development,and zebrafish maternal-to-zygotic transition.However,the roles of YTHDF2 in mammalian spermatogenesis are uncertain.Here,we generated germ cell-specific Ythdf2 mutants(Ythdf2-vKO)at a C57BL/6J background and demonstrated that YTHDF2 is essential for mouse spermatogenesis and fertility.Ythdf2-vKO provides oligoasthenoteratozoospermia phenotype with increased apoptosis in germ cells.High-throughput RNA-seq analysis showed that a group of mRNAs is upregulated in Ythdf2-vKO mouse testis;further analysis and MeRIP-qPCR data showed that most of the upregulated genes in Ythdf2-vKO mouse testis are modified with m^(6)A and are YTHDF2 candidate binding genes.Interestingly,RNA-seq analysis combined with our previous single-cell transcriptomics data of mouse spermatogenesis pointed out the failure of a wave of transcript transition during the spermatogenesis of Ythdf2-vKO mice,which was confirmed by gene expression analysis using qPCR of diplotene spermatocytes and round spermatids obtained through fluorescence-activated cell sorting.Our study demonstrates the fundamental role of YTHDF2 during mouse spermatogenesis and provides a potential candidate for the diagnosis of male infertility with the oligoasthenoteratozoospermia syndrome. | Xinxi Zhao Zhen Lin Yong Fan Wenzhi Li Yujie Zhang Fei Li Tong Hong Hua Feng Minghan Tong Ningling Wang Yanping Kuang Qifeng Lyu | 2021 | Acta Biochimica et Biophysica Sinica2021，53，12： | 2 |
| 4 | Angiotensin Ⅱ type Ⅰ receptor agonistic autoantibody-induced apoptosis in neonatal rat cardiomyocytes is dependent on the generation of tumor necrosis factor-α显示文摘血管收缩素 II 类型我受体论战的自身抗体(AT1-AA ) 与子间前和高血压有关并且有在胎盘刺激肿瘤坏死 factor-alpha (TNF-) 的生产的直接效果。TNF- 是 apoptosis 的一个已知的调停人。然而,很少研究在 cardiomyocytes 的 AT1-AA-induced apoptosis 以内报导了 TNF- 和它的关系的角色。在这研究,新生的老鼠 cardiomyocytes 与 AT1-AA 的各种各样的集中被对待。新生的老鼠 cardiomyocytes 的 apoptosis 是坚定的使用 TUNEL 试金和流动 cytometry。分泌 TNF- 的水平被连接酶的 immunosorbent 试金测量,并且 caspase-3 活动被一个 fluorogenic 朊酶试金工具包测量。AT1 受体封锁和 TNF 禁止者被增加决定他们是否能禁止 AT1-AA 的 apoptotic 效果。结果证明 AT1-AA 在一个剂量依赖者和时间依赖者举止导致了新生的老鼠 cardiomyocytes 的 apoptosis。AT1-AA 增加了 TNF 分泌物和 caspase-3 活动。AT1 受体封锁完全废除了 AT1-AA-induced TNF- 分泌物, caspase-3 激活,和 cardiomyocyte apoptosis。TNF- 受体禁止者显著地稀释的 AT1-AA-induced 新生的老鼠 cardiomyocyte apoptosis。在 pre 惊厥的病人的血浆的 AT1-AA 通过表明小径的 TNF-caspase 支持了新生的老鼠 cardiomyocyte apoptosis。 | Weiran Chai Wenhui Zhang Zhu Jin Yiping Feng Yanping Kuang Jianming Zhi | 2012 | Acta Biochimica et Biophysica Sinica2012，44，12： | 1 |

| 6 | A new panel containing specific spermatogenesis markers to identify spermatogenic cells in nonobstructive azoospermia patients显示文摘Infertility is a severe problem that affects 10%-15% of couples worldwide, among which male infertility is a factor in ~50% of the cases [1]. Azoospermia, which is defined as the absence of sperm in at least two ejaculates, can be divided into two types: obstructive azoospermia (OA) and non-OA (NOA)[1]. OA patients have normal spermatogenesis and mature sperm in testes and can father a biological child through testicular sperm retrieval and intracytoplasmic sperm injection (ICSI)[2]. By contrast, NOA patients usually have various degrees of spermatogenesis impairment and can be faced with complicated assisted reproductive technology (ART) strategies to father a biological child [2]. The precise diagnosis of spermatogenesis in NOA patients is crucial for clinical decision making regarding ART. | Xinxi Zhao Yiqin Wang Meng Ma Wei Zhang Jiqiang Si Wei Wang Zhen Lin Gang Han Charlie Degui Chen Minghan Tong Yanping Kuang Qifeng Lyu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，6： | 1 |

| 8 | Morphine Re-arranges Chromatin Spatial Architecture of Primate Cortical Neurons显示文摘The expression of linear DNA sequence is precisely regulated by the three-dimensional(3D)architecture of chromatin.Morphine-induced aberrant gene networks of neurons have been extensively investigated;however,how morphine impacts the 3D genomic architecture of neurons is still unknown.Here,we applied digestion-ligation-only high-throughput chromosome conformation capture(DLO Hi-C)technology to investigate the effects of morphine on the 3D chromatin architecture of primate cortical neurons.After receiving continuous morphine administration for 90 days on rhesus monkeys,we discovered that morphine re-arranged chromosome territories,with a total of 391 segmented compartments being switched.Morphine altered over half of the detected topologically associated domains(TADs),most of which exhibited a variety of shifts,followed by separating and fusing types.Analysis of the looping events at kilobase-scale resolution revealed that morphine increased not only the number but also the length of differential loops.Moreover,all identified differentially expressed genes from the RNA sequencing data were mapped to the specific TAD boundaries or differential loops,and were further validated for changed expression.Collectively,an altered 3D genomic architecture of cortical neurons may regulate the gene networks associated with morphine effects.Our finding provides critical hubs connecting chromosome spatial organization and gene networks associated with the morphine effects in humans. | Liang Wang Xiaojie Wang Chunqi Liu Wei Xu Weihong Kuang Qian Bu Hongchun Li Ying Zhao Linhong Jiang Yaxing Chen Feng Qin Shu Li Qinfan Wei Xiaocong Liu Bin Liu Yuanyuan Chen Yanping Dai Hongbo Wang Jingwei Tian Gang Cao Yinglan Zhao Xiaobo Cen | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
| 9 | Pyk2 suppresses contextual fear memory in an autophosphorylation-independent manner显示文摘Clustered protocadherins(Pcdhs)are a large family of cadherin-like cell adhesion proteins that are central for neurite selfavoidance and neuronal connectivity in the brain.Their downstream nonreceptor tyrosine kinase Pyk2(proline-rich tyrosine kinase 2,also known as Ptk2b,Cakb,Raftk,Fak2,and Cadtk)is predominantly expressed in the hippocampus.We constructed Pyk2-null mouse lines and found that these mutant mice showed enhancement in contextual fear memory,without significant change in auditory-cued and spatial-referenced learning and memory.In addition,by preparing Y402F mutant mice,we observed that Pyk2 suppressed contextual fear memory in an autophosphorylation-independent manner.Moreover,using high-throughput RNA sequencing,we found that immediate early genes,such as Npas4,cFos,Zif268/Egr1,Arc,and Nr4a1,were enhanced in Pyk2-null mice.We further showed that Pyk2 disruption affected pyramidal neuronal complexity and spine dynamics.Thus,we demonstrated that Pyk2 is a novel fear memory suppressor molecule and Pyk2-null mice provide a model for understanding fearrelated disorders.These findings have interesting implications regarding dysregulation of the Pcdh–Pyk2 axis in neuropsychiatric disorders. | Jin Zheng Lun Suo Yuxiao Zhou Liling Jia Jingwei Li Yanping Kuang Donghong Cui Xuehong Zhang Qiang Wu | 2021 | Journal of Molecular Cell Biology2021，13，11： | 0 |
