| 1 | MiR-122 in hepatic function and liver diseases显示文摘As the most abundant liver-specific microRNA,mi-croRNA-122(miR-122)is involved in various physio-logical processes in hepatic function as well as in liver pathology.There is now compelling evidence that miR-122,as a regulator of gene networks and pathways in hepatocytes,plays a central role in diverse aspects of hepatic function and in the progress of liver diseases.This liver-enriched transcription factors-regulated miRNA promotes differentiation of hepatocytes and regulates lipid metabolism.With regard to liver diseases,miR-122 was shown to stimulate hepatitis C virus(HCV)replication through a unique and unusual interaction with two binding sites in the 5′-UTR of HCV genome to mediate the stability of the viral RNA,whereas inhibit the expression and replication of hepatitis B virus(HBV)by a miR-122-cylin G1/p53-HBV enhancer regulatory pathway.In addition,miR-122 acts as a suppressor of cell prolif-eration and malignant transformation of hepatocytes with remarkable tumor inhibition activity.Notably,a clinical trial targeting miR-122 with the anti-miR-122 oli-gonucleotides miravirsen,the first miRNA targeted drug,has been initiated for treatment of HCV infection.With further understanding of the comprehensive roles of miR-122 in hepatic functions and the mechanisms in-volved in miR-122 down-regulation in chronic hepatitis or hepatocellular carcinoma,miR-122 appears to be a promising candidate for effective therapeutic ap-proaches against tumor and infectious diseases. | Jun Hu Yaxing Xu Junli Hao Saifeng Wang Changfei Li Songdong Meng | 2012 | Protein & Cell2012，3，5： | 22 |
| 2 | The histone methyltransferase EZH2 primes the early differentiation of follicular helper T cells during acute viral infection显示文摘Epigenetic modifications to histones dictate the differentiation of naïve CD4^(+) T cells into different subsets of effector T helper(TH)cells.The histone methyltransferase enhancer of zeste homolog 2(EZH2)has been implicated in the mechanism regulating the differentiation of TH1,TH2 and regulatory T(Treg)cells.However,whether and how EZH2 regulates follicular helper T(TFH)cell differentiation remain unknown.Using a mouse model of acute lymphocytic choriomeningitis virus(LCMV)infection,we observed abundant EZH2 expression and associated H3K27me3 modifications preferentially in the early committed virus-specific TFH cells compared to those in TH1 cells.Ablation of EZH2 in LCMV-specific CD4^(+) T cells leads to a selective impairment of early TFH cell fate commitment,but not late TFH differentiation or memory TFH maintenance.Mechanistically,EZH2 specifically stabilizes the chromatin accessibility of a cluster of genes that are important for TFH fate commitment,particularly B cell lymphoma 6(Bcl6),and thus directs TFH cell commitment.Therefore,we identified the chromatin-modifying enzyme EZH2 as a novel regulator of early TFH differentiation during acute viral infection. | Xiangyu Chen Guoshuai Cao Jialin Wu Xinxin Wang Zhiwei Pan Jianbao Gao Qin Tian Lifan Xu Zhirong Li Yaxing Hao Qizhao Huang Pengcheng Wang Minglu Xiao Luoyingzi Xie Shupei Tang Zhenyu Liu Li Hu Jianfang Tang Ran He Li Wang Xinyuan Zhou Yuzhang Wu Mengjie Chen Beicheng Sun Bo Zhu Jun Huang Lilin Ye | 2020 | Cellular & Molecular Immunology2020，17，3： | 4 |

| 5 | TiO_(2) nanorods based self-supported electrode of 1T/2H MoS_(2) nanosheets decorated by Ag nano-particles for efficient hydrogen evolution reaction显示文摘Molybdenum disulfide(MoS_(2))has shown significant promise as an economic hydrogen evolution reaction(HER)catalyst for hydrogen generation,but its catalytic performance is still lower than noble metalbased catalysists.Herein,a silver nanoparticles(Ag NPs)-decorated 1T/2H phase layered MoS_(2) electrocatalyst grown on titanium dioxide nanorod arrays(Ag NPs/1T(2H)MoS_(2)/TNRs)was prepared through acid-tunable ammonium ion intercalation.Taking advantage of MoS_(2) layered structure and crystal phase controllability,as-prepared Ag NPs/1T(2H)MoS_(2)/TNRs exhibited ultrahigh HER activity.As-proposed strategy combines facile hydrogen desorption(Ag NPs)with efficient hydrogen adsorption(1T/2H MoS_(2))effectively circumventes the kinetic limitation of hydrogen desorption by 1T/2H MoS_(2).The as-prepared Ag NPs/1T(2H)MoS_(2)/TNRs electrocatalyst exhibited excellent HER activity in 0.5 mol/L H2SO4 with low overpotential(118 mV vs.reversible hydrogen electrode(RHE))and small Tafel slope(38.61 mV/dec).The overpotential exhibts no obvious attenuation after 10 h of constant current flow.First-principles calculation demonstrates that as-prepared 1T/2H MoS_(2) exhibit a large capacity to store protons.These protons can be subsequently transferred to Ag NPs,which significantly increases the hydrogen coverage on the surface of Ag NPs in HER process and thus change the rate-determining step of HER on Ag NPs from water dissociation to hydrogen recombination.This study provides a unique strategy to improve the catalytic activity and stability for MoS_(2)-based electrocatalyst. | Changzheng Lin Yunpeng Liu Yaxing Sun Zhenyu Wang Hao Xu Mingtao Li Jiangtao Feng Bo Hou Wei Yan | 2023 | Chinese Chemical Letters2023，34，11： | 0 |
