    Overexpression of LACTB, a Mitochondrial Protein That Inhibits Proliferation and Invasion in Glioma Cells

    Hai-Tao Li, Dao-Yong Dong, Qiang Liu, Yi-Qin Xu, Langbo Chen

    Oncology Research, Vol.27, No.4, pp. 423-429, 2019, DOI:10.3727/096504017X15030178624579

    Abstract LACTB, a mitochondrial protein, was ubiquitously expressed in different mammalian tissues, such as liver, heart, and skeletal muscle. It has been shown that LACTB is downexpressed in breast cancers, and it suppresses the proliferation and promotes the apoptosis of breast cancers. However, its role in the progression and prognosis of glioma remains unknown. In this study, we analyzed the clinicopathological features and outcomes of LACTB expression in 98 glioma patients and investigated the effects of LACTB overexpression on the proliferation, invasion, and angiogenesis of glioma cells in vitro. We observed a significant decrease in LACTB expression in glioma, and downexpression… More >

    Jihong Sun*†1, Jingjing Li†1, Zhixian Guo, Lu Sun†‡, Chenghui Juan§, Yubing Zhou, Hongli Gu, Yan Yu, Qiuyue Hu, Quancheng’ Kan, Zujiang Yu

    Oncology Research, Vol.27, No.4, pp. 407-417, 2019, DOI:10.3727/096504018X15180451872087

    Abstract Most cancers rely disproportionately on glycolysis for energy even in the presence of an adequate oxygen supply, a condition known as “aerobic glycolysis,” or the “Warburg effect.” Pyruvate dehydrogenase E1 subunit (PDHA1) is one of the main factors for the metabolic switch from oxidative phosphorylation (OXPHOS) to aerobic glycolysis and has been suggested to be closely associated with tumorigenesis. Here we observed that the PDHA1 protein was reduced in hepatocellular carcinoma (HCC) specimens by immunohistochemistry and Western blot, which was significantly associated with poor overall survival. To further analyze the function of PDHA1 in cancer cells, PDHA1 was upregulated in… More >

    CMC-Computers, Materials & Continua, Vol.73, No.1, pp. 953-963, 2022, DOI:10.32604/cmc.2022.028958

    Abstract One of the most difficult jobs in the post-genomic age is identifying a genetic disease from a massive amount of genetic data. Furthermore, the complicated genetic disease has a very diverse genotype, making it challenging to find genetic markers. This is a challenging process since it must be completed effectively and efficiently. This research article focuses largely on which patients are more likely to have a genetic disorder based on numerous medical parameters. Using the patient’s medical history, we used a genetic disease prediction algorithm that predicts if the patient is likely to be diagnosed with a genetic disorder. To… More >

    BIOCELL, Vol.46, No.7, pp. 1733-1746, 2022, DOI:10.32604/biocell.2022.015784

    Abstract Darwin’s finches are the most classic case of evolution. Early studies on the evolution of this species were mainly based on morphology. Until now, the mitochondrial genome of Geospiza magnirostris has been sequenced and the study explored the characteristics of the complete genome of G. magnirostris and verified the evolutionary position of it. The 13 PCGs initiated by ATN codons. The stop codons of three PCGs (ND2, COX3 and ND4) were incomplete, with only T- or TA- replacing complete form TAA or TAG. All the tRNA genes expressed a typical cloverleaf secondary structure, except for tRNASer1(AGY), whose dihydrouridine (DHU) arm… 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 >

    Nitric Oxide Regulates Mitochondrial Fatty Acids and Promotes CBF Expression of Peach Fruit during Cold Storage

    Xiaoshan Guo1,2, Dandan Huang2, Siyu Wen2, Yang Bai2, Shuhua Zhu2,*, Jianrong Feng1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.2, pp. 409-427, 2022, DOI:10.32604/phyton.2022.018022

    Abstract Low-temperature storage is convenient for postharvest preservation of peach fruit, but peach fruit is sensitive to cold damage, which lowers its quality. Nitric oxide (NO) has the potential to improve the bitter resistance of peach fruit. In this work, peach fruit was treated with 15 μmol L−1 NO and 5 μmol L−1 c-PTIO [2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxo-3-oxide], to study changes in mitochondrial fatty acids and expression of the C-repeat binding factor (CBF). The results showed that 15 μmol L−1 exogenous NO significantly maintained fruit quality, reduced peroxidation of mitochondrial fatty acids, increased the activities of the antioxidants superoxide dismutase (SOD), peroxidase (POD), catalase… More >

    BIOCELL, Vol.45, No.4, pp. 1059-1067, 2021, DOI:10.32604/biocell.2021.015261

    Abstract Nicotine and menthol, agonists of nicotinic acetylcholine receptor (nAChR) and transient receptor potential melastatin type 8 (TRPM8), serve important roles in the prevention of cell death-involved neurodegenerative diseases. However, the potential synergistic effects of nicotine and menthol on anti-apoptotic ability are still uncertain. In the present study, the potential synergistic effects of nicotine and menthol on cisplatin or amyloid β1-42 induced cell model of the neurodegenerative diseases were explored by assessing cell viability, TNF-α expression, caspase-3 activation, and the collapse of mitochondrial membrane potential in human SH-SY5Y neuroblastoma cells. Statistical significance was tested using Student’s t-test or one-way ANOVA with… More >

    Abstract Amyotrophic lateral syndrome (ALS) is a progressive degenerative disorder characterized by motor neuron death and axon degeneration. Mitochondrial dysfunction plays a key role in the pathogenesis of ALS, the mechanism of which remains poorly understood. The B-cell lymphoma-2 (Bcl-2) family of proteins that control and mediate mitochondrial function and apoptosis, including the pro-apoptotic members Bcl2-Associated X (Bax), are involved in ALS development. The death receptor 6 (DR6) regulates motor neuron death in ALS, and DR6 antibodies can prevent axon degeneration and motor neuron damage by blocking DR6. Previous studies demonstrated that PSAP localized to mitochondria and was required for DR6-induced… More >

    BIOCELL, Vol.45, No.3, pp. 761-772, 2021, DOI:10.32604/biocell.2021.014602

    Abstract Various factors can induce cell degeneration by altering the phenotype and metabolism of cells. Mitochondria play an essential role in cellular homeostasis and function, rendering aging processes highly associated with mitochondrial function and status. Herein, we describe an aging-prone phenotype of murine skin cells caused by depletion of Rad6B (Ube2b), an E2 ubiquitin-conjugating enzyme. In this study, using Masson’s trichrome, we showed that loss of Rad6B causes physiological structure changes in mouse skin with age. In addition, a combination of western blotting experiments, transmission electron microscopy and employment of immunofluorescence staining revealed that depletion of Rad6B was characterized by an… More >
