    Effects and mechanisms of exosomes in microenvironment angiogenesis in breast cancer: An updated review

    JUNPING LIU1,2, FEIRAN GAO1, DANTING WANG2, RUIXUE ZHOU2, CHUNYAN HUANG2,*

    Oncology Research, Vol.33, No.6, pp. 1323-1334, 2025, DOI:10.32604/or.2024.059113 - 29 May 2025

    Abstract Exosomes (EXOs) play an important role in the progression of breast cancer. EXOs, with a diameter of approximately 100 nm, have a simple structure but diverse functions, and can affect the development of breast cancer through signal transduction and molecular transfer, etc. Angiogenesis provides nutrients for the growth and metastasis of breast cancer and is a crucial part of tumor progression. The mechanism of tumor angiogenesis is complex. The VEGF/VEGFR pathway promotes angiogenesis by regulating the activities of ECs. Hypoxia, a common feature in the tumor microenvironment, as a key regulator, can affect angiogenesis… More > Graphic Abstract

    Melanoma-derived extracellular vesicles transfer proangiogenic factors

    MAGDALENA WILCZAK1,2,#, MAGDALENA SURMAN1,#,*, MAłGORZATA PRZYBYłO1,*

    Oncology Research, Vol.33, No.2, pp. 245-262, 2025, DOI:10.32604/or.2024.055449 - 16 January 2025

    Abstract Angiogenesis, the expansion of pre-existing vascular networks, is crucial for normal organ growth and tissue repair, but is also involved in various pathologies, including inflammation, ischemia, diabetes, and cancer. In solid tumors, angiogenesis supports growth, nutrient delivery, waste removal, and metastasis. Tumors can induce angiogenesis through proangiogenic factors including VEGF, FGF-2, PDGF, angiopoietins, HGF, TNF, IL-6, SCF, tryptase, and chymase. This balance is disrupted in tumors, and extracellular vesicles (EVs) contribute to this by transferring proangiogenic factors and increasing their expression in endothelial cells (ECs). Malignant melanoma, a particular type of skin cancer, accounts for More >

    MINGYUE HUANG1,#, JUNFEI DAI1,#, XIANLIANG ZHONG2, JIN WANG2, JIANZHONG XU2, BO DU2,*

    BIOCELL, Vol.48, No.6, pp. 889-896, 2024, DOI:10.32604/biocell.2024.050097 - 10 June 2024

    Abstract Chronic subdural hematoma (CSDH) is a disease characterized by capsuled blood products that progressively occupy the intracranial space, causing intracranial hypertension and compression in the brain. CSDH frequently occurs in all demographics, especially in the elderly, but the pathogenesis of CSDH remains unclear. In this review, we discuss the origin, development, and current treatment strategies of CSDH. For the first time, we analyzed the cellular and molecular compositions of hematoma membranes with a focus on neomembrane formation, a complex early-stage interactive event in hematoma pathogenesis. We hypothesize that in patients with CSDH, dural border cells… More >

    VAN THI TUONG NGUYEN1,2, KHUONG DUY PHAM1,2,3, HUONG THI QUE CAO1,2, PHUC VAN PHAM1,2,*

    BIOCELL, Vol.48, No.2, pp. 173-189, 2024, DOI:10.32604/biocell.2023.043664 - 23 February 2024

    Abstract Mesenchymal stem cells (MSCs) have been proposed in regenerative medicine, especially for angiogenic purposes, due to their potential to self-renew, differentiate, and regulate the microenvironment. Peripheral vascular diseases, which are associated with reduced blood supply, have been treated but not cured. An effective therapy is to recover blood supply via vessel regeneration in the affected area, and MSCs appear to be promising for such conditions. Several studies aimed to explore the role of MSCs in performing angiogenesis and have revealed numerous potential methods to enhance MSC capacity in vessel formation. Efforts have been made to More > Graphic Abstract

    Gastric cancer secreted miR-214-3p inhibits the anti-angiogenesis effect of apatinib by suppressing ferroptosis in vascular endothelial cells

    WEIXUE WANG#, TONGTONG WANG#, YAN ZHANG, TING DENG, HAIYANG ZHANG*, YI BA*

    Oncology Research, Vol.32, No.3, pp. 489-502, 2024, DOI:10.32604/or.2023.046676 - 06 February 2024

    Abstract Different from necrosis, apoptosis, autophagy and other forms of cell death, ferroptosis is a mechanism that catalyzes lipid peroxidation of polyunsaturated fatty acids under the action of iron divalent or lipoxygenase, leading to cell death. Apatinib is currently used in the third-line standard treatment of advanced gastric cancer, targeting the anti-angiogenesis pathway. However, Apatinib-mediated ferroptosis in vascular endothelial cells has not been reported yet. Tumor-secreted exosomes can be taken up into target cells to regulate tumor development, but the mechanism related to vascular endothelial cell ferroptosis has not yet been discovered. Here, we show that More >
