    Revealing the role of honokiol in human glioma cells by RNA-seq analysis


    BIOCELL, Vol.48, No.6, pp. 945-958, 2024, DOI:10.32604/biocell.2024.049748

    Abstract Background: Glioma is a kind of tumor that easily deteriorates and originates from glial cells in nerve tissue. Honokiol is a bisphenol compound that is an essential monomeric compound extracted from the roots and bark of Magnoliaceae plants. It also has anti-infection, antitumor, and immunomodulatory effects. In this study, we found that honokiol induces cell apoptosis in the human glioma cell lines U87-MG and U251-MG. However, the mechanism through which honokiol regulates glioma cell apoptosis is still unknown. Methods: We performed RNA-seq analysis of U251-MG cells treated with honokiol and control cells. Protein-protein interaction (PPI)… More > Graphic Abstract

    Influence of Ultra Fine Glass Powder on the Properties and Microstructure of Mortars

    Wei Chen*, Dingdan Liu, Yue Liang

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.5, pp. 915-938, 2024, DOI:10.32604/fdmp.2024.046335

    Abstract This study focuses on the effect of ultrafine waste glass powder on cement strength, gas permeability and pore structure. Varying contents were considered, with particle sizes ranging from 2 to 20 μm. Moreover, alkali activation was considered to ameliorate the reactivity and cementitious properties, which were assessed by using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and specific surface area pore size distribution analysis. According to the results, without the addition of alkali activators, the performance of glass powder mortar decreases as the amount of glass powder increases, affecting various aspects such as strength… More >

    A Randomized Controlled Open-Label Pilot Study of Simvastatin Addition to Whole-Brain Radiation Therapy in Patients With Brain Metastases

    Manal El-Hamamsy*, Hesham Elwakil, Amr S. Saad, May A. Shawki*

    Oncology Research, Vol.24, No.6, pp. 521-528, 2016, DOI:10.3727/096504016X14719078133528

    Abstract Statins have been reported to have a potential radiosensitizing effect that has not been evaluated in clinical trials. The aim of this study was to evaluate the efficacy and safety of simvastatin in addition to whole-brain radiation therapy (WBRT) in patients with brain metastases (BM). A prospective randomized, controlled, open-label pilot study was conducted on 50 Egyptian patients with BM who were randomly assigned to receive 30-Gy WBRT (control group: 25 patients) or 30 Gy WBRT+ simvastatin 80 mg/day for the WBRT period (simvastatin group: 25 patients). The primary outcome was radiological response at 4… More >

    Knockdown of Collagen Triple Helix Repeat Containing-1 Inhibits the Proliferation and Epithelial-to-Mesenchymal Transition in Renal Cell Carcinoma Cells

    Xue-fei Jin, Hai Li, Shi Zong, Hong-yan Li

    Oncology Research, Vol.24, No.6, pp. 477-485, 2016, DOI:10.3727/096504016X14685034103716

    Abstract Collagen triple helix repeat containing-1 (CTHRC1), a secreted glycoprotein, is frequently upregulated in human cancers. However, the functional role of CTHRC1 in renal cell carcinoma (RCC) remains unclear. Thus, the aim of this study was to explore the role of CTHRC1 in RCC. Our results demonstrated that CTHRC1 was upregulated in RCC tissues and cell lines. Knockdown of CTHRC1 significantly inhibits the proliferation in RCCs. Furthermore, knockdown of CTHRC1 significantly inhibited the epithelial-to-mesenchymal transition (EMT) process in RCCs, as well as suppressed RCC cell migration and invasion. Mechanistically, knockdown of CTHRC1 inhibited the expression of More >

    Inhibition of Proliferation, Migration, and Invasion by Knockdown of Pyruvate Kinase-M2 (PKM2) in Ovarian Cancer SKOV3 and OVCAR3 Cells

    Yi Miao1, Meng Lu1, Qin Yan, Shuangdi Li, Youji Feng

    Oncology Research, Vol.24, No.6, pp. 463-475, 2016, DOI:10.3727/096504016X14685034103671

    Abstract Pyruvate kinase (PK) is a key enzyme in the process of glycolysis, catalyzing phosphoenolpyruvate (PEP) into pyruvate. Currently, PK isozyme type M2 (PKM2), one subtype of PK, has been proposed as a new tumor marker with high expression in various tumor tissues. Here we aimed to explore the effects of siRNAPKM2 on ovarian carcinoma (OC) cell lines SKOV3 and OVCAR3, in which PKM2 was notably expressed. PKM2 gene interference lentivirus vectors were built by miRNA transfection assay. siRNA-PKM2-transfected SKOV3 and OVCAR3 cells were evaluated for cell proliferation, cell cycle distribution, cell apoptosis, cell migration, and More >

    Associations between Social Media Use and Sleep Quality in China: Exploring the Mediating Role of Social Media Addiction

    Yijie Ye1, Han Wang2, Liujiang Ye1, Hao Gao1,*

    International Journal of Mental Health Promotion, Vol.26, No.5, pp. 361-376, 2024, DOI:10.32604/ijmhp.2024.049606

    Abstract Sleep quality is closely linked to people’s health, and during the COVID-19 pandemic, the sleep patterns of residents in China were notably poor. The lockdown in China led to an increase in social media use, prompting questions about its impact on sleep. Therefore, this study investigates the association between social media use and sleep quality among Chinese residents during the COVID-19 outbreak, highlighting the potential mediating role of social media addiction. Data were collected via questionnaires through a cross-sectional survey with 779 valid responses. Variance analysis was used to test for differences in social media… More >

    Tao Liang, Xiao-Yong Hu, Yong-Hui Li, Bin-Qiang Tian, Zuo-Wei Li, Qiang Fu

    Oncology Research, Vol.24, No.5, pp. 371-380, 2016, DOI:10.3727/096504016X14685034103356

    Abstract MicroRNA-21 (miRNA-21), a kind of short, noncoding RNAs, functioned as a tumor marker and was upregulated in renal cell carcinoma (RCC). However, the underlying mechanisms of miRNA-21 in RCC were uncertain. Therefore, the effects and mechanisms of miRNA-21 on the proliferation, differentiation, and apoptosis of cultured human RCC cells were further investigated in this study. After slicing miRNA-21 in RCC cells, the viability, mRNA expression of C/EBPα and PPARγ, caspase 3 activity, and protein expression of mTOR, STAT3, and pSTAT3 were determined. It was found that knockdown of miRNA-21 downregulated the optical density (OD) value More >
