    SBL-JP-0004: A promising dual inhibitor of JAK2 and PI3KCD against gastric cancer

    HASSAN M. OTIFI*

    Oncology Research, Vol.33, No.1, pp. 235-243, 2025, DOI:10.32604/or.2024.055677 - 20 December 2024

    Abstract Background: Gastric cancer (GC) remains a global health burden and is often characterized by heterogeneous molecular profiles and resistance to conventional therapies. The phosphoinositide 3-kinase and PI3K and Janus kinase (JAK) signal transducer and activator of transcription (JAK-STAT) pathways play pivotal roles in GC progression, making them attractive targets for therapeutic interventions. Methods: This study applied a computational and molecular dynamics simulation approach to identify and characterize SBL-JP-0004 as a potential dual inhibitor of JAK2 and PI3KCD kinases. KATOIII and SNU-5 GC cells were used for in vitro evaluation. Results: SBL-JP-0004 exhibited a robust binding affinity for… More >

    Abstract Oral ulcers, a common mucosal affliction, severely diminish patients’ quality of life due to pain and discomfort. Despite existing treatments, the frequent recurrence of oral ulcers underscores the need for more effective therapeutic options. This study aimed to investigate the inhibitory effects of Ponkan (Citrus reticulata ‘Ponkan’) extracts and their flavonoid components on oral ulcers, exploring their potential as a natural therapy. Twenty different Ponkan cultivars were selected for flavonoid extraction and analysis. Ultra-performance liquid chromatography (UPLC) and high-resolution mass spectrometry (HRMS) were utilized for substance identification, leading to the discovery of 16 flavonoid compounds.

    Oleanolic acid inhibits colon cancer cell stemness and reverses chemoresistance by suppressing JAK2/STAT3 signaling pathway

    RUOYU CHEN1, YIMAN WU1, FENG WANG1, JUNTAO ZHOU1, HUAZHANG ZHUANG1, WEI LI2,*

    BIOCELL, Vol.48, No.7, pp. 1037-1046, 2024, DOI:10.32604/biocell.2024.051074 - 03 July 2024

    Abstract Background: Oleanolic acid (OA), a pentacyclic triterpenoid exhibiting specific anti-cancer properties and highly effective antioxidant activity, was isolated from traditional Chinese medicinal herbs. Conversely, the OA that impacts colon cancer (CC) cells and its underlying mechanisms remain poorly understood. Methods: The cytotoxic effect of OA alone or OA-5-Fluorouracil (5-FU) combination on normal and CC cells was analyzed by methyl thiazolyl diphenyl-tetrazolium bromide (MTT). Then, the impact of OA on CC cell lines (LoVo and HT-29) proliferation and stemness were measured using colon formation and tumorsphere formation assays. Octamer-binding transcription factor 4 (Oct4), Prominin-1 (CD133), Nanog,… More >

    Galectin 2 regulates JAK/STAT3 signaling activity to modulate oral squamous cell carcinoma proliferation and migration in vitro

    XINRU FENG1, LI XIAO2,*

    BIOCELL, Vol.48, No.5, pp. 793-801, 2024, DOI:10.32604/biocell.2024.048395 - 06 May 2024

    Abstract Background: Galectin 2 (LGALS2) is a protein previously reported to serve as a mediator of disease progression in a range of cancers. The function of LGALS2 in oral squamous cell carcinoma (OSCC), however, has yet to be explored, prompting the present study to address this literature gap. Methods: Overall, 144 paired malignant tumor tissues and paracancerous OSCC patient samples were harvested and the LGALS2 expression levels were examined through qPCR and western immunoblotting. The LGALS2 coding sequence was introduced into the pcDNA3.0 vector, to enable the overexpression of this gene, while an LGALS2-specific shRNA and… More >

    JIANBO ZHOU1,2,3, FENG WAN2,4, BIN XIAO5, XIN LI1, CHENG PENG2,*, FU PENG1,3,*

    Oncology Research, Vol.32, No.5, pp. 943-953, 2024, DOI:10.32604/or.2023.044775 - 23 April 2024

    Abstract Breast and lung cancers are the leading causes of mortality and most frequently diagnosed cancers in women and men, respectively, worldwide. Although the antitumor activity of chalcones has been extensively studied, the molecular mechanisms of isoliquiritigenin analog 2', 4', 4-trihydroxychalcone (metochalcone; TEC) against carcinomas remain less well understood. In this study, we found that TEC inhibited cell proliferation of breast cancer BT549 cells and lung cancer A549 cells in a concentration-dependent manner. TEC induced cell cycle arrest in the S-phase, cell migration inhibition in vitro, and reduced tumor growth in vivo. Moreover, transcriptomic analysis revealed that TEC More > Graphic Abstract

    Abstract Background: The development and prognosis of breast cancer are intricately linked to psychological stress. In addition, depression is the most common psychological comorbidity among breast cancer survivors, and reportedly, Fang-Xia-Dihuang decoction (FXDH) can effectively manage depression in such patients. However, its pharmacological and molecular mechanisms remain obscure. Methods: Public databases were used for obtaining active components and related targets. Main active components were further verified by ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS). Protein–protein interaction and enrichment analyses were taken to predict potential hub targets and related pathways. Molecule docking was used to understand the interactions… More >

    Abstract Background: Nano-selenium has been widely used in antiviral and anticancer therapy, and has the advantages of good targeting and low toxicity. For the first time, we combined male reproduction with nano-selenium to investigate its antioxidant effect. This study investigated the protective effect of lentinan functionalized selenium nanoparticles on oxidative stress injury of the hydrogen peroxide (H2O2)-induced Leydig cell line, TM3. Methods: The suitable concentration of nano-selenium treatment to promote cell proliferation was also discussed. The concentration of 4 μM could significantly promote the growth of TM3 cells. Oxidative stress damage was caused using an 800 μM concentration… More >

    miRNA-148b-3p targeting SOCS3 inhibits macrophage M2 polarization by JAK2/STAT3 pathway in immune thrombocytopenia

    YANG YANG, LIJUAN FU, CHUNMEI CHEN, MEIWEI HU

    BIOCELL, Vol.46, No.5, pp. 1319-1328, 2022, DOI:10.32604/biocell.2022.015760 - 06 January 2022

    Abstract Aberrant expression of miRNAs is significantly correlated with the occurrence of immune thrombocytopenic purpura (ITP). The immune imbalance of M1/M2 macrophage contributes to the development of ITP. However, the role of miR-148b-3p in macrophage phenotype imbalance remains unknown in ITP. In this study, we aimed to explore whether miR-148b-3p inhibits M2 macrophage polarization in ITP and to investigate the underlying mechanism. Peripheral blood from 22 ITP patients were collected, and real-time PCR confirmed that miR-148b-3p was up-regulated and Western blot analyses detected the expression of SOCS3 was down-regulated. Subsequent dual-luciferase reporter gene assay indicated that More >

    YUE WANG1,#, YINPING DUAN1,#, KUNLIN CHEN3, HUIXIA LI1,2,*, YAN QUAN4,*

    BIOCELL, Vol.45, No.2, pp. 307-316, 2021, DOI:10.32604/biocell.2021.014305 - 19 February 2021

    Abstract Non-alcoholic fatty liver disease is the most common cause of hepatic dysfunction. In the present study, human normal hepatocyte L02 cells were treated with 50% fetal bovine serum to induce the formation of hepatic steatosis in vitro, and then the cells were treated with docosahexaenoic acid to investigate its protective effect on Non-alcoholic fatty liver disease. Our results showed that 50% of fetal bovine serum significantly induced intracellular lipid accumulation and hepatocyte fatty degeneration within 48 h. The expression level of adipose formation-related genes was significantly up-regulated, such as PPARγ, C/EBPα and SREBP-1; meanwhile, the content… More >

    Basic Transcription Factor 3 Is Required for Proliferation and Epithelial–Mesenchymal Transition via Regulation of FOXM1 and JAK2/STAT3 Signaling in Gastric Cancer

    De-Zhong Zhang*, Bing-He Chen*, Lan-Fang Zhang, Ming-Kun Cheng, Xiang-Jie Fang*, Xin-Jun Wu*

    Oncology Research, Vol.25, No.9, pp. 1453-1462, 2017, DOI:10.3727/096504017X14886494526344

    Abstract Gastric cancer (GC) is the most common epithelial malignancy worldwide. Basic transcription factor 3 (BTF3) plays a crucial role in the regulation of various biological processes. We designed experiments to investigate the molecular mechanism underlying the role of BTF3 in GC cell proliferation and metastasis. We confirmed that BTF3 expression was decreased in GC tissues and several GC cell lines. Lentivirus-mediated downregulation of BTF3 reduced cell proliferation, induced S and G2/M cell cycle arrest, and increased apoptosis. Knockdown of BTF3 significantly reduced the expression of Forkhead box M1 (FOXM1). Upregulation of FOXM1 significantly inhibited the decrease… More >
