6Regulation of superoxide flashes by transient and steady mitochondrial calcium elevations显示文摘The mitochondria play essential roles in both intracellular calcium and reactive oxygen species signaling.As a newly discovered universal and fundamental mitochondrial phenomenon,superoxide flashes reflect transient bursts of superoxide production in the matrix of single mitochondria.Whether and how the superoxide flash activity is regulated by mitochondrial calcium remain largely unknown.Here we demonstrate that elevating mitochondrial calcium either by the calcium ionophore ionomycin or by increasing the bathing calcium in permeabilized HeLa cells increases superoxide flash incidence,and inhibition of the mitochondrial calcium uniporter activity abolishes the flash response.Quantitatively,the superoxide flash incidence is correlated to the steady-state mitochondrial calcium elevation with 1.7-fold increase per 1.0?F/F0 of Rhod-2 signal.In contrast,large mitochondrial calcium transients(e.g.,peak△F/F0~2.8,duration^2 min)in the absence of steady-state elevations failed to alter the flash activity.These results indicate that physiological levels of sustained,but not transient,mitochondrial calcium elevation acts as a potent regulator of superoxide flashes,but its mechanism of action likely involves a multi-step,slow-onset process.JIAN ChongShu HOU TingTing YIN RongKang CHENG HePing WANG XianHua 2014Science China(Life Sciences)2014,57,5:5
7Noble-metal-free catalyst with enhanced hydrogen evolution reaction activity based on granulated Co-doped Ni-Mo phosphide nanorod arrays显示文摘The development of noble-metal-free electrocatalysts for water splitting is indispensable for the efficient production of hydrogen fuel.Herein,a Co-doped Ni-Mo phosphide nanorod arrays fabricated on porous Ni foam was shown to be an efficient binder-free electrocatalyst for water splitting.This catalyst featured exceptional activity,exhibiting an overpotential of 29 mV at a current density of 10 mA·cm−2 for the hydrogen evolution reaction,whereas the corresponding precatalyst exhibited an overpotential of 314 mV at a current density of 50 mA·cm^−2 for the oxygen evolution reaction.The achieved electrocatalytic performance provided access to a simple water splitting system,affording a current density of 10 mA·cm^−2 at 1.47 V in 1 M KOH electrolyte.Density functional theory results indicated that Co doping and phosphorization were responsible for the high electrocatalytic performance.Thus,this work paves the way for the development of novel noble-metal-free electrocatalysts for practical H2 production via water splitting.Heping Xie Cheng Lan Bin Chen Fuhuan Wang Tao Liu 2020Nano Research2020,13,12:4
8NDUFAB1 confers cardio-protection by enhancing mitochondrial bioenergetics through coordination of respiratory complex and supercomplex assembly显示文摘The impairment of mitochondrial bioenergetics,often coupled with exaggerated reactive oxygen species (ROS) production, is a fundamental disease mechanism in organs with a high demand for energy, including the heart. Building a more robust and safer cellular powerhouse holds the promise for protecting these organs in stressful conditions. Here, we demonstrate that NADH:ubiquinone oxidoreductase subunit AB1 (NDUFAB1), also known as mitochondrial acyl carrier protein, acts as a powerful cardio-protector by conferring greater capacity and efficiency of mitochondrial energy metabolism. In particular, NDUFAB1 not only serves as a complex I subunit, but also coordinates the assembly of respiratory complexes I, II, and III, and supercomplexes, through regulating iron-sulfur biosynthesis and complex I subunit stability. Cardiac-specific deletion of Ndufab1 in mice caused defective bioenergetics and elevated ROS levels, leading to progressive dilated cardiomyopathy and eventual heart failure and sudden death. Overexpression of Ndufab1 effectively enhanced mitochondrial bioenergetics while limiting ROS production and protected the heart against ischemia-reperfusion injury. Together, our findings identify that NDUFAB1 is a crucial regulator of mitochondrial energy and ROS metabolism through coordinating the assembly of respiratory complexes and supercomplexes, and thus provide a potential therapeutic target for the prevention and treatment of heart failure.Tingting Hou Rufeng Zhang Chongshu Jian Wanqiu Ding Yanru Wang Shukuan Ling Qi Ma Xinli Hu Heping Cheng Xianhua Wang 2019Cell Research2019,29,9:4
9Role of JAK-STAT3 signaling pathway during neuronal differentiation of rat bone marrow mesenchymal stem cells显示文摘BACKGROUND: Recent studies regarding neuronal differentiation of mesenchymal stem cells (MSCs) have primarily focused on induction methods and transplantation in vivo.However,knowledge about the intrinsic regulatory mechanisms underlying neuronal induction of MSCs remains limited and unclear.OBJECTIVE: To elucidate the role of JAK-STAT3 signaling pathway during neuronal differentiationof MSCs using a combination of the JAK-STAT3 signaling inhibitor AG490 and growth factors.DESIGN,TIME AND SETTING: Neural,molecular,biomedical,in vitro experiment was performed at the Laboratory of Pharmacology,School of Pharmacy,Nanjing Medical University between Marchand December 2008 MATERIALS: An inhibitor of the JAK-STAT3 signaling pathway was purchased from Calbiochem,USA.Antibody kit for total and phosphorylated STAT3 was purchased from Cell Signaling,USA.METHODS: MSCs from passage 3 were assigned to non-induced,growth factor,and AG490 groups.MAIN OUTCOME MEASURE: The number of cells expressing neuron-specific enolase,microtubule-associated protein,and glial fibrillary acidic protein were determined by immunocytochemistry.Total and phosphorylated (Tyr705) expression levels of STAT3 protein were measured by Western blot analysis.RESULTS: MSCs were transdifferentiated into neuronaland astrocyte-like phenotypes throughthe induction of epidermal growth factor,basic fibroblast growth factor,and brain-derived neurotrophic factor.In addition,the JAK-STAT3 signaling pathway was significantly activated during neural differentiation.Expression of phosphorylated (Tyr705) STAT3 was inhibited with AG490 (5 μmol/L) prior to neural induction with epidermal growth factor,basic fibroblast growth factor,and brain-derived neurotrophic factor;proportion of astrocyte-like cells was significantly reduced (P < 0.01),and the proportion of neuronal-like phenotypes was significantly increased (P < 0.01).CONCLUSION: JAK-STAT3 signaling pathway was shown to regulate neuronal induction of bone marrow MSCs.The proportion of MSC-induced neuronal-like cells was increased following treatment with the JAK-STAT3 signaling inhibitor AG490.Huaiyong Hao Yongguang Wang Feng Cheng Baosheng Huang Heping Tian Xueliang Dai Lixin Li 2010Neural Regeneration Research2010,5,5:2

13Electrochemical CO_(2) mineralization for red mud treatment driven by hydrogen-cycled membrane electrolysis显示文摘CO_(2)mineralization as a promising CO_(2)mitigation strategy can employ industrial alkaline solid wastes to achieve net emission reduction of atmospheric CO_(2).The red mud is a strong alkalinity waste residue produced from the aluminum industry by the Bayer process which has the potential for the industrial CO_(2)large scale treatment.However,limited by complex components of red mud and harsh operating conditions,it is challenging to directly mineralize CO_(2)using red mud to recover carbon and sodium resources and to produce mineralized products simultaneously with high economic value efficiently.Herein,we propose a novel electrochemical CO_(2)mineralization strategy for red mud treatment driven by hydrogen-cycled membrane electrolysis,realizing mineralization of CO_(2)efficiently and recovery of carbon and sodium resources with economic value.The system utilizes H_(2)as the redox-active proton carrier to drive the cathode and anode to generate OH^(-) and H^(+) at low voltage,respectively.The H^(+) plays as a neutralizer for the alkalinity of red mud and the OH^(-) is used to mineralize CO_(2)into generate highpurity NaHCO_(3)product.We verify that the system can effectively recover carbon and sodium resources in red mud treatment process,which shows that the average electrolysis efficiency is 95.3%with highpurity(99.4%)NaHCO_(3)product obtained.The low electrolysis voltage of 0.453 V is achieved at10 mA·cm^(-2) in this system indicates a potential low energy consumption industrial process.Further,we successfully demonstrate that this process has the ability of direct efficient mineralization of flue gas CO_(2)(15%volume)without extra capturing,being a novel potential strategy for carbon neutralization.Heping Xie Yunpeng Wang Tao Liu Yifan Wu Wenchuan Jiang Cheng Lan Zhiyu Zhao Liangyu Zhu Dongsheng Yang 2022Chinese Journal of Chemical Engineering2022,35,3:2
