| 1 | Single-cell RNA-seq analysis of testicular somatic cell development in pigs显示文摘Spermatogenesis is the process by which diploid male germ cells propagate and differentiate into haploid flagellated spermatozoa.This highly complicated process is dependent on testicular somatic cells maturation.While the role of these somatic cells in spermatogenesis is relatively well established,knowledge about their development and maturation,particularly at the molecular level,is limited.In this study,we profiled the testicular single-cell transcriptomes of Guanzhong black pigs at the age of 7,30,60,90,and 150 days.Five types of Sertoli cells,five types of Leydig cells,and four types of peritubular myoid cells were identified.Histological analysis revealed the changes in proliferation levels and marker gene expressions,and the prion-like protein gene(PRND)was identified as a novel marker for Sertoli cells.Additionally,integrated analyses of porcine and human datasets revealed similarities between human and pig testicular somatic cells.Overall,the data obtained in this study contribute to the understanding of testicular development in pigs as a model species. | Lingkai Zhang Ming Guo Zidong Liu Ruifang Liu Yi Zheng Taiyong Yu Yinghua Lv Hongzhao Lu Wenxian Zeng Tao Zhang Chuanying Pan | 2022 | Journal of Genetics and Genomics2022，49，11： | 4 |
| 2 | Single-cell RNA-sequencing reveals the dynamic process and novel markers in porcine spermatogenesis显示文摘Background:Spermatogenesis is the process by which male gametes are formed from spermatogonial stem cells and it is essential for the reliable transmission of genetic information between generations.To date,the dynamic transcriptional changes of defined populations of male germ cells in pigs have not been reported.Results:To characterize the atlas of porcine spermatogenesis,we profiled the transcriptomes of~16,966 testicular cells from a 150-day-old pig testis through single-cell RNA-sequencing(scRNA-seq).The scRNA-seq analysis identified spermatogonia,spermatocytes,spermatids and three somatic cell types in porcine testes.The functional enrichment analysis demonstrated that these cell types played diverse roles in porcine spermatogenesis.The accuracy of the defined porcine germ cell types was further validated by comparing the data from scRNA-seq with those from bulk RNA-seq.Since we delineated four distinct spermatogonial subsets,we further identified CD99 and PODXL2 as novel cell surface markers for undifferentiated and differentiating spermatogonia,respectively.Conclusions:The present study has for the first time analyzed the transcriptome of male germ cells and somatic cells in porcine testes through scRNA-seq.Four subsets of spermatogonia were identified and two novel cell surface markers were discovered,which would be helpful for studies on spermatogonial differentiation in pigs.The datasets offer valuable information on porcine spermatogenesis,and pave the way for identification of key molecular markers involved in development of male germ cells. | Lingkai Zhang Fuyuan Li Peipei Lei Ming Guo Ruifang Liu Ling Wang Taiyong Yu Yinghua Lv Tao Zhang Wenxian Zeng Hongzhao Lu Yi Zheng | 2022 | Journal of Animal Science and Biotechnology2022，13，2： | 2 |
| 3 | Transcriptome-wide Dynamics of m^(6)A mRNA Methylation During Porcine Spermatogenesis显示文摘Spermatogenesis is a continual process that occurs in the testes,in which diploid spermatogonial stem cells(SSCs)differentiate and generate haploid spermatozoa.This highly efficient and intricate process is orchestrated at multiple levels.N^(6)-methyladenosine(m^(6)A),an epigenetic modification prevalent in mRNAs,is implicated in the transcriptional regulation during spermatogenesis.However,the dynamics of m^(6)A modification in non-rodent mammalian species remains unclear.Here,we systematically investigated the profile and role of m^(6)A during spermatogenesis in pigs.By analyzing the transcriptomic distribution of m^(6)A in spermatogonia,spermatocytes,and round spermatids,we identified a globally conserved m^(6)A pattern between porcine and murine genes with spermatogenic function.We found that m^(6)A was enriched in a group of genes that specifically encode the metabolic enzymes and regulators.In addition,transcriptomes in porcine male germ cells could be subjected to the m^(6)A modification.Our data show that m^(6)A plays the regulatory roles during spermatogenesis in pigs,which is similar to that in mice.Illustrations of this point are three genes(SETDB1,FOXO1,and FOXO3)that are crucial to the determination of the fate of SSCs.To the best of our knowledge,this study for the first time uncovers the expression profile and role of m^(6)A during spermatogenesis in large animals and provides insights into the intricate transcriptional regulation underlying the lifelong male fertility in non-rodent mammalian species. | Zidong Liu Xiaoxu Chen Pengfei Zhang Fuyuan Li Lingkai Zhang Xueliang Li Tao Huang Yi Zheng Taiyong Yu Tao Zhang Wenxian Zeng Hongzhao Lu Yinghua Lv | 2023 | Genomics, Proteomics & Bioinformatics2023，21，4： | 1 |
| 4 | 3D bioprinted hyaluronic acid‑based cell‑laden scaffold for brain microenvironment simulation显示文摘Treatments for lesions in central nervous system(CNS)are always faced with challenges due to the anatomical and physiological particularity of the CNS despite the fact that several achievements have been made in early diagnosis and precision medicine to improve the survival and quality of life of patients with brain tumors in recent years.Understanding the complexity as well as role of the microenvironment of brain tumors may suggest a better revealing of the molecular mechanism of brain tumors and new therapeutic directions,which requires an accurate recapitulation of the complex microenvironment of human brain in vitro.Here,a 3D bioprinted in vitro brain matrix-mimetic microenvironment model with hyaluronic acid(HA)and normal glial cells(HEBs)is developed which simulates both mechanical and biological properties of human brain microenvironment in vivo through the investigation of the formulation of bioinks and optimization of printing process and parameters to study the effects of different concentration of gelatin(GA)within the bioink and different printing structures of the scaffold on the performance of the brain matrix-mimetic microenvironment models.The study provides experimental models for the exploration of the multiple factors in the brain microenvironment and scaffolds for GBM invasion study. | Liang Ma Yuting Li Yutong Wu Mengfei Yu Abdellah Aazmi Lei Gao Qian Xue Yichen Luo Hongzhao Zhou Bin Zhang Huayong Yang | 2020 | Bio-Design and Manufacturing2020，3，3： | 1 |
| 5 | Functions and mechanisms of protein lysine butyrylation(Kbu):Therapeutic implications in human diseases显示文摘Post-translational modifications(PTM)are covalent modifications of proteins or peptides caused by proteolytic cleavage or the attachment of moieties to one or more amino acids.PTMs play essential roles in biological function and regulation and have been linked with several diseases.Modifications of protein acylation(Kac),a type of PTM,are known to induce epigenetic regulatory processes that promote various diseases.Thus,an increasing number of studies focusing on acylation modifications are being undertaken.Butyrylation(Kbu)is a new acylation process found in animals and plants.Kbu has been recently linked to the onset and progression of several diseases,such as cancer,cardiovascular diseases,diabetes,and vascular dementia.Moreover,the mode of action of certain drugs used in the treatment of lymphoma and colon cancer is based on the regulation of butyrylation levels,suggesting that butyrylation may play a therapeutic role in these diseases.In addition,butyrylation is also commonly involved in rice gene expression and thus plays an important role in the growth,development,and metabolism of rice.The tools and analytical methods that could be utilized for the prediction and detection of lysine butyrylation have also been investigated.This study reviews the potential role of histone Kbu,as well as the mechanisms underlying this process.It also summarizes various enzymes and analytical methods associated with Kbu,with the goal of providing new insights into the role of Kbu in gene regulation and diseases. | Qianqian Xue Yanyan Yang Hong Li Xiaoxin Li Lu Zou Tianxiang Li Huibo Ma Hongzhao Qi Jianxun Wang Tao Yu | 2023 | Genes & Diseases2023，10，6： | 0 |
| 6 | CRISPR/Cas9 therapeutics:progress and prospects显示文摘Clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)gene-editing technology is the ideal tool of the future for treating diseases by permanently correcting deleterious base mutations or disrupting disease-causing genes with great precision and efficiency.A variety of efficient Cas9 variants and derivatives have been developed to cope with the complex genomic changes that occur during diseases.However,strategies to effectively deliver the CRISPR system to diseased cells in vivo are currently lacking,and nonviral vectors with target recognition functions may be the focus of future research.Pathological and physiological changes resulting from disease onset are expected to serve as identifying factors for targeted delivery or targets for gene editing.Diseases are both varied and complex,and the choice of appropriate gene-editing methods and delivery vectors for different diseases is important.Meanwhile,there are still many potential challenges identified when targeting delivery of CRISPR/Cas9 technology for disease treatment.This paper reviews the current developments in three aspects,namely,gene-editing type,delivery vector,and disease characteristics.Additionally,this paper summarizes successful examples of clinical trials and finally describes possible problems associated with current CRISPR applications. | Tianxiang Li Yanyan Yang Hongzhao Qi Weigang Cui Lin Zhang Xiuxiu Fu Xiangqin He Meixin Liu Pei-feng Li Tao Yu | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 0 |
| 7 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 8 | Systemic delivery of microRNA for treatment of brain ischemia显示文摘Brain ischemia is the second leading cause of death and the third leading cause of disability in the world.Systemic delivery of microRNA,a class of molecules that regulate the expression of cellular proteins associated with angiogenesis,cell growth,proliferation and differentiation,holds great promise for the treatment of brain ischemia.However,their therapeutic efficacy has been hampered by poor delivery efficiency of microRNA.We report herein a platform technology based on microRNA nanocapsules,which enables their effective delivery to the disease sites in the brain.Exemplified by microRNA-21,intravenous injection of the nanocapsules into a rat model of cerebral ischemia could effectively ameliorate the infarct volume,neurological deficit and histopathological severity. | Chaoyong Liu Jing Wen Dai Li Hongzhao Qi Lina Nih Jialin Zhu Duo Xu Yu Ren Shanshan Zhang Donglin Han Huanhuan Jia Junhu Zhou Meng Qin Jialing Wu Xubo Yuan Ji Liu Jin Zhao Chunsheng Kang Yunfeng Lu | 2021 | Nano Research2021，14，9： | 0 |
| 9 | Modulation of neuronal activity of cerebellar fastigial nucleus by locus coeruleus stimulation in the rat显示文摘The effects of stimulating locus coeruleus (LC) on neuronal activity of cerebellar fastigial nucleus (FN) was investigated. Stimulation of LC elicited inhibitory, excitatory and biphasic (inhibition-excitation) responses from FN cells. The majority of responsive cells showed an inhibitory response with a latency of less than 10 ms. Injection of α adrenoreceptor antagonists phentolamine (ⅳ) could block the inhibitory response of FN cells to the LC stimulation, but propranolol (ⅳ), a β adrenoreceptor antagonist, could not. These results suggest that LC-cerebellar noradrenergic afferent fibers may be involved in the cerebellar sensorimotor integration process by exerting their modulatory action on the cerebellar nuclear cells’ activities. | Wang Tao Wang Jianjun Cheng Hong Li Hongzhao Yu Qixiang | 1998 | Chinese Science Bulletin1998，43，11： | 0 |
| 10 | Constructing biomimetic liver models through biomaterials and vasculature engineering显示文摘The occurrence of various liver diseases can lead to organ failure of the liver,which is one of the leading causes of mortality worldwide.Liver tissue engineering see the potential for replacing liver transplantation and drug toxicity studies facing donor shortages.The basic elements in liver tissue engineering are cells and biomaterials.Both mature hepatocytes and differentiated stem cells can be used as themain source of cells to construct spheroids and organoids,achieving improved cell function.To mimic the extracellular matrix(ECM)environment,biomaterials need to be biocompatible and bioactive,which also help support cell proliferation and differentiation and allow ECM deposition and vascularized structures formation.In addition,advancedmanufacturing approaches are required to construct the extracellular microenvironment,and it has been proved that the structured three-dimensional culture system can help to improve the activity of hepatocytes and the characterization of specific proteins.In summary,we review biomaterials for liver tissue engineering,including natural hydrogels and synthetic polymers,and advanced processing techniques for building vascularized microenvironments,including bioassembly,bioprinting and microfluidic methods.We then summarize the application fields including transplant and regeneration,disease models and drug cytotoxicity analysis.In the end,we put the challenges and prospects of vascularized liver tissue engineering. | Weikang Lv Hongzhao Zhou Abdellah Aazmi Mengfei Yu Xiaobin Xu Huayong Yang Yan Yan Shery Huang Liang Ma | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 11 | Engineered Vasculature for Organ-on-a-Chip Systems显示文摘Organ-on-a-chip technology,a promising three-dimensional(3D)dynamic culture method,ensures accu-rate and efficient cell culture and has great potential for replacing animal models in preclinical testing.The circulatory system,the most abundant organ in the human body,plays a crucial role in oxygen exchange and mass transfer,which is the determining factor for the survival of tissues and organs.Thus,it is essential to integrate the circulatory system into an organ-on-a-chip to recreate tissue and organ microenvironments and physiological functions.This review discusses the synergy between the vasculature and the emerging organ-on-a-chip technology,which offers even better possibilities of dupli-cating physiology and disease characteristics.In addition,we review the different steps of a vascularized organ-on-a-chip fabrication process,including structure fabrication and tissue construction using differ-ent biofabrication strategies.Finally,we outline the applicability of this technology in the fascinating and fast-developing field of organ and tumor culture. | Abdellah Aazmi Hongzhao Zhou Yuting Li Mengfei Yu Xiaobin Xu Yutong Wu Liang Ma Bin Zhang Huayong Yang | 2022 | Engineering2022，8，2： | 0 |
