    Guang Chen1, Shiwang Dang1, Fanpeng Kong2, Lingchong Hu1, Zhiming Zhang1, Yi Guo3, Xue Pei1, Jichao Li1,4,*

    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.11, pp. 2721-2740, 2025, DOI:10.32604/fdmp.2025.068889 - 01 December 2025

    Abstract To enhance the navigation efficiency of inland new-energy ships and reduce energy consumption and emissions, this study investigates wind load coefficients under 13 conditions, combining a wind speed of 2.0 m/s with wind direction angles ranging from 0° to 180° in 15° increments. Using Computational Fluid Dynamics (CFD) simulations, the wind load is decomposed into along-course (CX) and transverse (CY) components, and their variation with wind direction is systematically analyzed. Results show that CX is maximal under headwind (0°), decreases approximately following a cosine trend, and reaches its most negative value under tailwind (180°). CY peaks at More >

    Molecular Mechanisms of Gemcitabine Resistance in Cholangiocarcinoma

    Sonexai Kidoikhammouan1, Charupong Saengboonmee2,3, Sopit Wongkham2,3, Wunchana Seubwai3,4,*

    Oncology Research, Vol.33, No.12, pp. 3679-3699, 2025, DOI:10.32604/or.2025.069027 - 27 November 2025

    Abstract Cholangiocarcinoma (CCA) is an aggressive cancer originating from bile duct epithelium. Surgical resection remains the primary curative treatment for CCA. However, most CCA patients are diagnosed at an advanced stage, which limits the applicability of surgical resection. Gemcitabine is widely used as a first-line chemotherapeutic agent for unresectable CCA. Its efficacy is often compromised by the development of drug resistance, which leads to poor clinical outcomes and low survival rates of CCA patients. At present, the mechanisms underlying gemcitabine resistance in CCA remain unclear. This review aimed to comprehensively summarize the current knowledge on the More >

    Yizhen Zhang1,2,#, Juan Li1,3,#, Huanqing Liu1,4,#, Hong Xia1, Jian Su1,5, Fang Liu1, Bo Su6,*, Qi Su1,*

    Oncology Research, Vol.33, No.12, pp. 3869-3886, 2025, DOI:10.32604/or.2025.068689 - 27 November 2025

    Abstract Objectives: Gastric cancer (GC) is often associated with high invasiveness, epithelial-mesenchymal transition (EMT), and resistance to 5-fluorouracil (5-FU), highlighting the need for novel therapeutic targets. This study explored whether diallyl disulfide (DADS) upregulates retinoic acid-related orphan receptor alpha (ROR) to weaken the protein kinase C alpha (PKC)/RORα-mediated RORα/β-catenin pathway, thereby inhibiting GC cell invasion, epithelial-mesenchymal transition (EMT), and enhancing 5-FU sensitivity. Methods: Human GC cell lines MGC-803 and SGC7901 were treated with DADS, RORα agonist SR1078/antagonist T0901317, and PKCα agonist TPA/antagonist GO6976. Cell proliferation (MTT), migration (scratch assay), invasion (Transwell), protein expression (Western blot), protein… More >

    Huan Wang1,#, Jindong Xie1,#, Na Li1, Qianwen Liu1, Wenqi Song1, Wenkuan Chen1, Cheng Peng2,*, Hailin Tang1,*

    Oncology Research, Vol.33, No.12, pp. 3789-3800, 2025, DOI:10.32604/or.2025.067592 - 27 November 2025

    Abstract Solid tumors comprise the majority of the global cancer burden, with their incidence and associated mortality posing considerable challenges to public health systems. With population growth and aging, the burden of these tumors is anticipated to increase further in the coming decades. The progression of solid tumors depends on dynamic interactions between malignantly transformed cells and the tumor microenvironment (TME). Immune checkpoint inhibitor therapy improves T cell-mediated antitumor activity by suppressing regulatory pathways, such as programmed cell death protein 1/programmed death-ligand 1. Nonetheless, its widespread application is constrained by drug resistance. In this comprehensive review, More >

    Ranran Yang1,2,3,#, Dan Yuan2,#, Chaohan Liang4,#, Siying Zhu4, Jie Huang2, Yingqi Zhang4, Weiling He5, Qinghai Li1,*, Hong Zhang2,*

    Oncology Research, Vol.33, No.12, pp. 3945-3971, 2025, DOI:10.32604/or.2025.064463 - 27 November 2025

    Abstract Background: Colorectal cancer (CRC) is a predominant contributor to global cancer-associated mortality worldwide. Oxaliplatin (OXP), a foundational chemotherapeutic agent for CRC, often exhibits limited efficacy due to the emergence of drug resistance. Although endothelin-1 (EDN1) has been implicated in tumor drug resistance, its role in oxaliplatin resistance in CRC remains poorly defined. This work aimed to define how EDN1 contributes to oxaliplatin resistance and to explore its potential as a therapeutic target. Methods: Public genomic datasets were analyzed to confirm EDN1 upregulation in colorectal cancer (CRC) and its association with poor prognosis. EDN1 expression was… More >

    Drug-Induced Insulin Sensitivity Impairments: Potential Involvement of Disturbed Mitochondrial Dynamics and Mitophagy Pathways

    Mutamba Ropafadzo Peace1, Thobeka Madide1,2, Ntethelelo Sibiya1,*

    BIOCELL, Vol.49, No.11, pp. 2069-2091, 2025, DOI:10.32604/biocell.2025.068017 - 24 November 2025

    Abstract The pathogenesis of insulin resistance is influenced by environmental factors, genetic predispositions, and several medications. Various drugs used to manage multiple ailments have been shown to induce insulin resistance, which could lead to Type II Diabetes mellitus (T2DM). Central to drug-induced insulin resistance is mitochondrial dysfunction. Amongst disturbed pathways in drug-induced mitochondrial toxicity is mitophagy, a process that removes dysfunctional mitochondria through the lysosomal pathways to maintain mitochondrial quality. A balance must always be maintained between mitochondrial dynamics and mitophagy, as any alterations may contribute to the pathogenesis of metabolic diseases such as diabetes mellitus.… More >

    Mechanistic Insights into the Role of Melatonin in Cancer Cell Chemoresistance

    Russel J. Reiter1,*, Ramaswamy Sharma2,*, Walter Manucha3, Walter Balduini4, Doris Loh5, Demetrios A. Spandidos6, Alejandro Romero7, Vasiliki E. Georgakopoulou8, Wei Zhu9

    BIOCELL, Vol.49, No.11, pp. 2033-2067, 2025, DOI:10.32604/biocell.2025.067661 - 24 November 2025

    Abstract The development of cancer cell resistance to conventional treatments continues to be a major obstacle in the successful treatment of tumors of many types. The discovery of a highly efficient direct and indirect free radical scavenger, melatonin, in the mitochondrial matrix may be a factor in determining both the occurrence of cancer cell drug insensitivity as well as radioresistance. This relates to two of the known hallmarks of cancer, i.e., exaggerated free radical generation in the mitochondria and the development of Warburg type metabolism (glycolysis). The hypothesis elaborated in this report assumes that the high… More >
