| 1 | Ascorbic acid accelerates Wallerian degeneration after peripheral nerve injury显示文摘Wallerian degeneration occurs after peripheral nerve injury and provides a beneficial microenvironment for nerve regeneration.Our previous study demonstrated that ascorbic acid promotes peripheral nerve regeneration,possibly through promoting Schwann cell proliferation and phagocytosis and enhancing macrophage proliferation,migration,and phagocytosis.Because Schwann cells and macrophages are the main cells involved in Wallerian degeneration,we speculated that ascorbic acid may accelerate this degenerative process.To test this hypothesis,400 mg/kg ascorbic acid was administered intragastrically immediately after sciatic nerve transection,and 200 mg/kg ascorbic acid was then administered intragastrically every day.In addition,rat sciatic nerve explants were treated with 200μM ascorbic acid.Ascorbic acid significantly accelerated the degradation of myelin basic protein-positive myelin and neurofilament 200-positive axons in both the transected nerves and nerve explants.Furthermore,ascorbic acid inhibited myelin-associated glycoprotein expression,increased c-Jun expression in Schwann cells,and increased both the number of macrophages and the amount of myelin fragments in the macrophages.These findings suggest that ascorbic acid accelerates Wallerian degeneration by accelerating the degeneration of axons and myelin in the injured nerve,promoting the dedifferentiation of Schwann cells,and enhancing macrophage recruitment and phagocytosis.The study was approved by the Southern Medical University Animal Care and Use Committee(approval No.SMU-L2015081)on October 15,2015. | Lixia Li Yizhou Xu Xianghai Wang Jingmin Liu Xiaofang Hu Dandan Tan Zhenlin Li Jiasong Guo | 2021 | Neural Regeneration Research2021，16，6： | 6 |
| 2 | 基因组和转录组测序整合分析揭示混合型肝癌的不同分子亚型显示文摘文章简介原发性肝癌每年造成全球约70万病人死亡且过半死亡病例来自中国,其致死率在所有癌种中高居第二。肝癌主要分为3种类型:肝细胞癌(约80%)、肝内胆管癌(约15%)和混合型肝癌(约5%)。混合型肝癌兼具肝细胞癌和胆管细胞癌两种成分,是预后最差的一种肝癌。 | 薛瑞栋 陈璐 张冲 藤田征志 Ruoyan Li Shu-Mei Yan Choon Kiat Ong Xiwen Liao Qiang Gao Shota Sasagawa Yanmeng Li Jincheng Wang Hua Guo Qi-Tao Huang Qian Zhong Jing Tan Lisha Qi Wenchen Gong Zhixian Hong Meng Li Jingmin Zhao Tao Peng Yinying Lu Kiat Hon Tony Lim Arnoud Boot Atushi Ono Kazuaki Chayama Zemin Zhang Steve George Rozen Bin Tean Teh Xin Wei Wang Hidewaki Nakagawa 曾木圣 白凡 张宁 | 2020 | 科学新闻2020，，2： | 0 |
| 3 | Vitamin D receptor (VDR) mediates the quiescence of activated hepatic stellate cells (aHSCs) by regulating M2 macrophage exosomal smooth muscle cell-associated protein 5 (SMAP-5)显示文摘An effective therapeutic regimen for hepatic fibrosis requires a deep understanding of the pathogenesis mechanism.Hepatic fibrosis is characterized by activated hepatic stellate cells(aHSCs)with an excessive production of extracellular matrix.Although promoted activation of HSCs by M2 macrophages has been demonstrated,the molecular mechanism involved remains ambiguous.Herein,we propose that the vitamin D receptor(VDR)involved in macrophage polarization may regulate the communication between macrophages and HSCs by changing the functions of exosomes.We confirm that activating the VDR can inhibit the effect of M2 macrophages on HSC activation.The exosomes derived from M2 macrophages can promote HSC activation,while stimulating VDR alters the protein profiles and reverses their roles in M2 macrophage exosomes.Smooth muscle cell-associated protein 5(SMAP-5)was found to be the key effector protein in promoting HSC activation by regulating autophagy flux.Building on these results,we show that a combined treatment of a VDR agonist and a macrophage-targeted exosomal secretion inhibitor achieves an excellent anti-hepatic fibrosis effect.In this study,we aim to elucidate the association between VDR and macrophages in HSC activation.The results contribute to our understanding of the pathogenesis mechanism of hepatic fibrosis,and provide potential therapeutic targets for its treatment. | Xuwentai LIU Yue WU Yanyi LI Kaiming LI Siyuan HOU Ming DING Jingmin TAN Zijing ZHU Yingqi TANG Yuming LIU Qianhui SUN Cong WANG Can ZHANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，3： | 0 |
