| 1 | Progress and mechanism of breaking glycoconjugates by glycosidases in skin for promoting unhairing and fiber opening-up in leather manufacture.A review显示文摘The glycoconjugates,herein glyco-proteins,existing in animal skins are closely related to the effectiveness of unhairing and fiber opening-up.Glycosidases have been used in leather making processes to reduce pollutants and improve leather quality.But the selection of glycosidases is still blind because the related mechanisms are not well understood yet.Hence,the animal skin structures and glycoconjugates components,the advances in the methods and mechanisms of removing glycoconjugates related to unhairing and fiber opening-up in leather manufacture,the kinds,compositions,structures and functions of typical glycoconjugates in skin are summarized.Then the approaches to destroy them,possible glycosidases suitable for leather making and their acting sites are analyzed based on the recognition of glycoconjugates in skin and the specificities of glycosidases toward substrates.It is expected to provide useful information for the optimization of glycosidases and the development of new enzymes and the cleaner technologies of unhairing and opening up fiber bundles assisted by glycosidases. | Fengxiang Luo Xiang Zhong Mengchu Gao Biyu Peng Zhongzhen Long | 2020 | Journal of Leather Science and Engineering2020，2，1： | 4 |

| 3 | Carbon and nitrogen budget in fish-polychaete integrated aquaculture system显示文摘Integrated multi-tropic aquaculture(IMTA)systems have been used in China for many years and have achieved significant economic,social,and ecological benefits.However,there is still a lack of benthic bioremediation species that can effectively utilize the aquaculture particulate organic waste in the system.Polychaete Perinereis aibuhitensis Grube is used as an environmental remediation species for large-scale aquaculture to reduce particulate organic waste,which is of great significance to environmental protection.To improve bio-elements utilization efficiency,P.aibuhitensis was applied for IMTA indoor fish(Hexagrammos otakii)farming.Results showed that in the system,production of 1 kg of the fish discharged 2141-2338 mg of carbon and 529-532 mg of nitrogen,while in the monoculture of the fish,the figures were 3033-3390 mg and 764-794 mg,or 24.84%-35.26%and 30.35%-33.32%less,respectively.This approach promoted IMTA technology that could utilize the particulate organic waste from intensive aquaculture and reduce the adverse environmental effects. | Fawen HU Ming SUN Jinghui FANG Guodong WANG Li LI Fengxiang GAO Yuxia JIAN Xue WANG Guangbin LIU Yan ZOU Wen GUO | 2021 | Journal of Oceanology and Limnology2021，39，3： | 1 |
| 4 | Effects of Environmental Cadmium on Cadmium Accumulation, Oxidative Response, and Microelements Regulation in the Liver and Kidney of Hexagrammos otakii显示文摘The effects of cadmium(Cd)on metal accumulation,microelements contents,and antioxidant responses in Hexagram-mos otakii were studied.The fish were exposed to 0.2,2.5,or 10μg L−1 Cd for 12 or 24 days.Then,the concentration of Cd and mi-croelements(Ca,Fe,Zn,and Se)were determined in the liver and kidney.Moreover,the activities of antioxidant enzymes including superoxide dismutase(SOD),catalase(CAT),and glutathione-S-transferase(GST),and the content of malondialdehyde(MDA)in the liver and kidney were also measured.A continuous accumulation of Cd was observed throughout the experimental period.Cd accumulation was higher in liver than that in the kidney,while Ca and Fe contents were lower in liver than those in the kidney.Cd exposure resulted in a decrease of Ca and Fe concentrations in the kidney,while there was no effect on the liver.Zn and Se remained unaffected with exposure to Cd.Cd exposure induced severe oxidative stress in H.otakii,as indicated by significant induction of the activities of SOD,CAT,and GST,and a simultaneous increase of MDA content.These data show that antioxidant enzymes and mi-croelements contents can be used as potential biomarkers to monitor environmental health in fish. | HU Fawen SUN Ming LI Li GAO Fengxiang JIAN Yuxia WANG Xue WANG Xiaolong GUO Wen | 2022 | Journal of Ocean University of China2022，21，2： | 0 |
| 5 | E3 ligase MG53 suppresses tumor growth by degrading cyclin D1显示文摘Due to the essential role of cyclin D1 in regulating transition from G1 to S phase in cell cycle,aberrant cyclin D1 expression is a major oncogenic event in many types of cancers.In particular,the dysregulation of ubiquitination-dependent degradation of cyclin D1 contributes to not only the pathogenesis of malignancies but also the refractory to cancer treatment regiments with CDK4/6 inhibitors.Here we show that in colorectal and gastric cancer patients,MG53 is downregulated in more than 80%of tumors compared to the normal gastrointestinal tissues from the same patient,and the reduced MG53 expression is correlated with increased cyclin D1 abundance and inferior survival.Mechanistically,MG53 catalyzes the K48-linked ubiquitination and subsequent degradation of cyclin D1.Thus,increased expression of MG53 leads to cell cycle arrest at G1,and thereby markedly suppresses cancer cell proliferation in vitro as well as tumor growth in mice with xenograft tumors or AOM/DSS induced-colorectal cancer.Consistently,MG53 deficiency results in accumulation of cyclin D1 protein and accelerates cancer cell growth both in culture and in animal models.These findings define MG53 as a tumor suppressor via facilitating cyclin D1 degradation,highlighting the therapeutic potential of targeting MG53 in treating cancers with dysregulated cyclin D1 turnover. | Meng Fang Hong-Kun Wu Yumeng Pei Yan Zhang Xiangyu Gao Yanyun He Gengjia Chen Fengxiang Lv Peng Jiang Yumei Li Wenwen Li Peng Jiang Lin Wang Jiafu Ji Xinli Hu Rui-Ping Xiao | 2023 | Signal Transduction and Targeted Therapy2023，8，8： | 0 |
