    Abstract

    Cadmium (Cd) causes oxidative stress, which leads to the oxidation of various biomolecules by the production of reactive oxygen species (ROS) to facilitate programmed cell death (PCD). The antioxidant defense system fails to detoxify ROS when it is produced in excess. Nitric oxide (NO), a gaseous free radical and a phytohormone, regulates various physiological processes of plants. Therefore, this work was undertaken to study the effects of the application of exogenous sodium nitroprusside (SNP, a NO donor) on growth parameters, oxidative stress, accumulation of secondary metabolites, and activities of antioxidant enzymes under Cd stress. Mild (50 µM) and severe (200… More >

    Zhongyuan Yin*, Lin Yang, Feng Wu, Jinshuo Fan, Juanjuan Xu, Yang Jin, Guanghai Yang§

    Oncology Research, Vol.27, No.9, pp. 1069-1077, 2019, DOI:10.3727/096504019X15566157027506

    Abstract Cysteine oxidation occurs at the active site of deubiquitinases (DUBs) during many biologic signaling cascades. Here we report that hepatocellular carcinoma cells (HCCs) generated higher levels of endogenous reactive oxygen species (ROS). This elevated ROS production was inhibited by NADPH oxidase inhibitor diphenylene iodonium (DPI) and mitochondria electron chain inhibitor rotenone in HCC cells. Moreover, we found that H2O2 could activate NF- B-dependent inflammatory effect through increased induction of matrix metalloproteinase 2 (MMP2), MMP9, and intercellular adhesion molecule 1 (ICAM1) expression levels. In addition, we found that H2O2 could prolong NF- B activation by suppressing the negative regulatory functions of… More >

    Qie Guo*, Xiao Li*, Meng-Na Cui*, Jia-Lin Sun*, Hong-Yan Ji*, Bei-Bei Ni*, Mei-Xing Yan

    Oncology Research, Vol.28, No.5, pp. 533-540, 2020, DOI:10.3727/096504020X15919605976853

    Abstract Cancer is one of the most serious diseases that are harmful to human health. Systemic chemotherapy is an optimal therapeutic strategy for the treatment of cancer, but great difficulty has been encountered in its administration in the form of multidrug resistance (MDR). As an enzyme on the outer cell surface, CD13 is documented to be involved in the MDR development of tumor cells. In this review, we will focus on the role of CD13 in MDR generation based on the current evidence. More >

    Taufika Islam Anee1,#, Md. Nur Nabi Islam1,#, Mohamed M. Hassan2, Abdul Awal Chowdhury Masud1, Md. Mahabub Alam1, Mirza Hasanuzzaman1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.9, pp. 1959-1972, 2022, DOI:10.32604/phyton.2022.021137

    Abstract Due to the unpredictable climate change, drought stress is being considered as one of the major threats to crop production. Wheat (Triticum aestivum L. cv. BARI Gom-26) being a dry season crop frequently faces scarcity of water and results in a lower yield. Therefore, this experiment aims to explore the role of different organic amendments (OAs) in mitigating drought stress-induced damage. The pot experiment consisted of different organic amendments viz. compost, vermicompost and poultry manure @0.09 kg m−2 soil, biochar @2.5% w/w soil and chitosan @1% w/w soil which was imposed on the plants grown under both well-watered and drought… More >

    Role of Reactive Oxygen Species in the Initiation of Plant Retrograde Signaling

    Eduardo-Antonio Trillo-Hernández1, Arturo Duarte Sierra2, Martín Ernesto Tiznado-Hernández1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.5, pp. 905-913, 2022, DOI:10.32604/phyton.2022.018118

    Abstract

    The interaction between the nucleus and the different organelles is important in the physiology of the plant. Reactive oxygen species (ROS) are a by-product of the oxidation of organic molecules to obtain energy by the need to carry out the electron transfer between the different enzymatic complexes. However, they also have a role in the generation of what is known as retrograde signaling. This signal comes from the different organelles in which the oxidation of molecules or the electron transference is taking place such as mitochondria and chloroplasts. Furthermore, ROS can also induce the release of signals from the apoplast.… More >

    Effects of High-Temperature Stress on Photosynthetic Characteristics and Antioxidant Enzyme System of Paeonia ostii

    Xiaoxiao Wang1, Ziwen Fang1, Daqiu Zhao1, Jun Tao1,2,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 599-615, 2022, DOI:10.32604/phyton.2022.017881

    Abstract

    Paeonia ostii is an economically important oil crop, which has been widely cultivated in the middle and lower reaches of the Yangtze River in China in recent years. Although P. ostii is highly adaptable to the environment, the prolonged high summer temperature in this region severely inhibits its growth, which adversely affects seed yield and quality. In this study, P. ostii plants were subjected to 20°C/15°C (day/night) and 40°C/35°C (day/night) temperatures for 15 days. The changes in physiological and biochemical indicators of P. ostii under high-temperature stress were initially investigated. The results showed that with the deepening of leaf etiolation,… More >

    Oxidative stress indicators in human and bottlenose dolphin leukocytes in response to a pro-inflammatory challenge

    TARYN E. SYMON1, RAMÓN GAXIOLA-ROBLES1,2, CLAUDIA J. HERNÁNDEZ-CAMACHO3, TANIA ZENTENO-SAVÍN1,*

    BIOCELL, Vol.45, No.6, pp. 1621-1630, 2021, DOI:10.32604/biocell.2021.016302

    Abstract Marine mammals undergo cycles of tissue ischemia and reperfusion during the dive response. Reperfusion injury can result in oxidative tissue damage and the activation of a pro-inflammatory immune response. The risk of oxidative damage is reduced by antioxidants. Our hypothesis is that the reported higher antioxidant defenses within marine mammal tissues provide additional protection in situations that produce oxidative stress, like inflammation, in comparison to terrestrial mammal tissues. Leukocytes were isolated from the whole blood of Pacific bottlenose dolphins (Tursiops truncatus gilli) and humans (Homo sapiens) and were exposed to lipopolysaccharides (LPS, 10 µg/mL) in vitro to simulate a pro-inflammatory… More >

    Mengyuan Dong#, Rong Sun#, Qianhui Yang, Lantian Zhang, Yangying Yong, Yunxia Fang, Xian Zhang, Xiaoqin Zhang*, Dawei Xue*

    Phyton-International Journal of Experimental Botany, Vol.90, No.6, pp. 1589-1598, 2021, DOI:10.32604/phyton.2021.017465

    Abstract In recent years, zinc oxide nanoparticles (ZnO NPs) have been widely used as zinc fertilizers and pesticides. The use of ZnO NPs in this way can provide benefits to humans, but also has potential risks. ZnO NPs inevitably enter the environment during their production and use, which affects the ecological environment and crop growth. In order to investigate the phenotype, physiology, and gene expression of barley (Hordeum vulgare L.) seedlings under ZnO NPs stress, the barely cultivars ZJU3 (P21), Golden Promise (GP) and L23 were chosen for study. Different ZnO NPs concentrations were applied to compare the physiological and biochemical… More >

    Abstract Traditional Chinese medicine (TCM) has been increasingly applied in both preventing and treating a variety of cancers in the last decades, attributing to its fewer side effects as compared with chemotherapy drugs. Hellebrigenin, a component of Chanpi from the skin of Bufo bufogargarizans Cantor or Duttaphrynus melanostictus has been reported to have an obvious anti-cancer activity on various cancers. However, the effect and mechanism of hellebrigenin on colorectal cancers were still unknown. Herein, the present study demonstrated hellebrigenin significantly reduced viability and triggered apoptosis via the intrinsic pathway in colorectal cancer cell lines HCT116 and HT29 in vitro and in… More >
