    Thrombospondin 1 Triggers Osteosarcoma Cell Metastasis and Tumor Angiogenesis

    Yue Kui Jian1, Huan Ye Zhu1, Xing Lin Wu, Bo Li

    Oncology Research, Vol.27, No.2, pp. 211-218, 2019, DOI:10.3727/096504018X15208993118389

    Abstract Osteosarcomas, especially those with metastatic or unresectable disease, have limited treatment options. The antitumor effects of pharmacologic inhibitors of angiogenesis in osteosarcomas are hampered in patients by the rapid development of tumor resistance, notably through increased invasiveness and accelerated metastasis. Here we demonstrated that thrombospondin 1 (TSP-1) is a potent inhibitor of the growth and metastasis of the osteosarcoma cell line MG-63. Moreover, we demonstrate that upregulation of TSP-1 facilitated expression of vasculostatin in MG-63 cells. In angiogenesis assays, overexpression of TSP-1 inhibited MG-63 cells and induced tube formation of human umbilical vein endothelial cells (HUVECs) in a CD36-dependent fashion.… More >

    Apatinib Plus Chemotherapy Shows Clinical Activity in Advanced NSCLC: A Retrospective Study

    Jing Tang*1, Xu Yong Li†1, Jing Bo Liang, De Wu§, Li Peng, Xiaobing Li

    Oncology Research, Vol.27, No.6, pp. 635-641, 2019, DOI:10.3727/096504018X15288447760357

    Abstract Apatinib is an oral TKI with antiangiogenic properties, and it is currently approved for the treatment of advanced gastric cancer in China. This agent has also been tested in other human solid tumors, including non-small cell lung cancer (NSCLC). Since the combination of chemotherapy and an antiangiogenic agent has been shown to be a feasible strategy in NSCLC, it is conceivable that a similar approach combining apatinib with chemotherapy may yield clinical activity. With this in mind, we investigated the efficiency of apatinib in combination with pemetrexed or docetaxel in advanced NSCLC. We treated a total of 20 patients with… More >

    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 >

    Heming Lu*†1, Yuying Wu‡1, Xu Liu, Huixian Huang, Hailan Jiang, Chaohua Zhu, Yuping Man§, Zhaohong Chen, Xianfeng Long, Qiang Pang, Luxing Peng, Xianglong Li, Junzhao Gu, Shan Deng, Ligang Xing*

    Oncology Research, Vol.28, No.9, pp. 929-944, 2020, DOI:10.3727/096504021X16318716607908

    Abstract This phase II randomized clinical trial aimed to assess the efficacy and toxicity of Endostar, an antiangiogenesis inhibitor, combined with concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC). Patients with LACC were randomly assigned to either CCRT plus Endostar (CCRT+E arm) or CCRT alone (CCRT arm). All patients received pelvic intensity-modulated radiation therapy (IMRT) and brachytherapy. Weekly cisplatin was administered concurrently with IMRT. Patients in the CCRT+E arm also received concurrent Endostar every 3 weeks for two cycles. The primary endpoint was progression-free survival (PFS) and acute toxicities. The exploratory endpoint was the impact of vascular endothelial growth factor… More >

    Intrauterine high androgen promotes obesity of the offspring of rats with polycystic ovarian syndrome via activating macrophage-angiogenesis-related androgen signaling


    BIOCELL, Vol.46, No.6, pp. 1505-1519, 2022, DOI:10.32604/biocell.2022.016564

    Abstract The development of polycystic ovary syndrome (PCOS) is closely related to the chronic inflammatory and obese. Recent studies have found macrophages regulate the chronic inflammation and adipose tissue remodelling, but the underlying mechanisms have not been clarified. In this study, we established a model of PCOS in the offspring rats by high androgen exposure during late pregnancy in parental and established a female rat macrophage eliminating model by rejection of clodronate liposome. Then, the offspring rat macrophage phenotype in offspring female rat adipose tissue, and levels of testosterone, angiogenic factors (PDGF and VEGF) and inflammatory factors (TNF-α and MCP-1) were… More >

    Platelet rich plasma–complexed hydrogel glue enhances skin wound healing in a diabetic rat model


    BIOCELL, Vol.46, No.5, pp. 1329-1338, 2022, DOI:10.32604/biocell.2022.015592

    Abstract Diabetic patients often exhibit delayed or incomplete progress in the healing of acute wounds, owing to poor blood perfusion. Platelet-rich plasma (PRP) has attracted much attention as a means to improve wound healing, because it contains high growth factor concentrations. However, the burst-like release of PRP growth factors results in a short half-life of these therapeutic proteins, thus greatly limiting the therapeutic effect. In this study, we prepared PRP from human umbilical cord blood and developed an in situ photocrosslinkable PRP hydrogel glue (HNPRP) by adding a photoresponsive hyaluronic acid (HA-NB) into PRP. The HNPRP hydrogel allowed for controlled release… More >

    MicroRNA-181a is elevated by 10-hydroxycamptothecin and represses lung carcinoma progression by downregulating FOXP1


    BIOCELL, Vol.46, No.2, pp. 417-431, 2022, DOI:10.32604/biocell.2022.015522

    Abstract Tumor progression is usually characterized by proliferation, migration, and angiogenesis, which is essential for supplying both nutrients and oxygen to the tumor cells. Therefore, targeting angiogenesis has been considered a promising therapeutic strategy for cancer prevention and treatment. In the present study, we demonstrated that in addition to suppressing lung cancer cell proliferation and migration in vitro, 10-hydroxycamptothecin (10-HCPT) is also capable of inhibiting angiogenesis in vivo with a miR-181a-dependent manner. Mechanistically, by upregulating miR-181a, which in turn downregulating FOXP1, 10-HCPT can inhibit the PI3K/Akt/ERK signaling pathwaymediated angiogenesis. Furthermore, reduced levels of miR-181a have been found in both lung cancer… More >

    Basing on microRNA-mRNA analysis identifies microRNA in exosomes associated with wound repair of diabetic ulcers


    BIOCELL, Vol.45, No.1, pp. 27-39, 2021, DOI:10.32604/biocell.2021.012601

    Abstract The diabetic ulcer is one of the serious complications of diabetes. In this study, we aimed to establish an exosomal microRNA (miRNA)-targeted messenger RNA (mRNA) regulatory network for screening new biomarkers for diabetic ulcer treatment. For this purpose, exosomes were extracted from bone marrow stem cells (BMSCs) collected from diabetic ulcer patients and healthy adults. The miRNAs in exosomes was detected by high-throughput sequencing analysis. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of the differential miRNAs were performed. The miRNA-mRNA regulatory network between candidate miRNAs and their target genes were constructed by… More >

    Neovascularization and Intraplaque Hemorrhage in Atherosclerotic Plaque Destabilization-A Mathematical Model

    Muyi Guo1, Yan Cai1, Zhiyong Li1,2,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.1, pp. 49-49, 2019, DOI:10.32604/mcb.2019.05727

    Abstract Observational studies have identified angiogenesis from the adventitial vasa vasorum and intraplaque hemorrhage (IPH) as critical factors in atherosclerotic plaque progression and destabilization. Here we propose a mathematical model incorporating intraplaque neovascularization and hemodynamic calculation for the quantitative evaluation of atherosclerotic plaque hemorrhage. An angiogenic microvasculature based on histology of a patient’s carotid plaque is generated by two-dimensional nine-point model of endothelial cell migration. Three key cells (endothelial cells, smooth muscle cells and macrophages) and three key chemicals (vascular endothelial growth factors, extracellular matrix and matrix metalloproteinase) are involved in the intraplaque angiogenesis model, and described by the reaction-diffusion partial… More >

    Endothelial cells as mechanical transducers: Enzymatic activity and network formation under cyclic strain

    A. Shukla1,1, A.R. Dunn2,2, M.A. Moses3,3, K.J. Van Vliet4,4

    Molecular & Cellular Biomechanics, Vol.1, No.4, pp. 279-290, 2004, DOI:10.3970/mcb.2004.001.279

    Abstract Although it is established that endothelial cells can respond to external mechanical cues (e.g., alignment in the direction of fluid shear stress), the extent to which mechanical stress and strain applied via the endothelial cell substrate impact biomolecular and cellular processes is not well-understood. This issue is particularly important in the context of inflammation, vascular remodeling, and cancer progression, as each of these processes occurs concurrently with localized increases in strain and marked changes in molecules secreted by adjacent cells. Here, we systematically vary the level and duration of cyclic tensile strain applied to human dermal microvascular and bovine capillary… More >
