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… More >

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 More >

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… More >

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 More >

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… More >

Abstract Sperm-associated antigen 9 (SPAG9) expression is increased in prostate tissues of prostate cancer patients. This experimental study aimed to investigate the role of SPAG9 in bone metastasis of prostate cancer. Immunohistochemical analysis showed that SPAG9 staining was positive in 81.67% of 240 cases of prostatic carcinoma but only in 6.67% of 120 cases of benign prostate hyperplasia. Strong PAG9 staining was positively correlated with Gleason score and bone metastasis in 240 prostate cancer patients (p < 0.05), but not with the age or serum prostatespecific antigen level (p > 0.05). PC-3 cells were transfected with shRNA… More >

Abstract Cancer cell-derived exosomes have been actively released into the tumor microenvironment with pleiotropic roles in tumor growth and metastasis, including angiogenesis and immune modulation. However, the functions and underlying mechanisms of exosomes shed by colorectal cancer (CRC) cells under hypoxic conditions remain unknown. Here we found that exosomes derived from hypoxic CRC cells promoted the proliferation and migration of endothelial cells. Suppression of exosome secretion through RAB27a knockdown in CRC cells inhibited exosomal-induced proliferation and migration of endothelial cells. Furthermore, we discovered that these exosomes enriched with Wnt4 were dependent on HIF1α. Exosomal Wnt4 increased More >

Abstract Shear stress and oxidized low-density lipoprotein (oxLDL) caused by abnormal blood is critical to angiogenesis for atherosclerosis. However, the mechanism in shear stress or ox-LDL regulated angiogenesis is still not well understood. There is the hypothesis that shear stress or oxLDL regulates angiogenesis through the vascular endothelial growth factor (VEGF) signaling pathway. It is discovered that both high shear stress and low concentration of oxLDL contribute to angiogenesis, which is inhibited once the VEGF or VEGFR expression is knocked down. The expression of p-FAK and p-paxillin is regulated by the VEGF/VEGFR signal axis. VEGFR2, p-FAK, More >

Abstract Abnormal shear stress in the blood vessel is an important stimulating factor for the formation of angiogenesis and vulnerable plaques. This paper intended to explore the role of shear stress-regulated Id1 in angiogenesis. First, we applied a carotid artery ring ligation to create local stenosis in ApoE^-/- mice. Then, 3D geometry of the vessel network was reconstructed based on MRI, and our analysis of computational fluid dynamics revealed that wall shear stress of the proximal region was much higher than that of the distal region. In addition, results from histological staining of the proximal region found More >

Abstract Extracellular signal-regulated kinase (ERK)1/2 signaling pathway plays a critical role in regulating tumor angiogenesis. Our previous studies have demonstrated that HPV-16 oncoproteins enhanced hypoxia-inducible factor-1α (HIF-1α) protein accumulation and vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) expression in non-small cell lung cancer (NSCLC) cells, thus contributing to angiogenesis. In this study, we further investigated the role of ERK1/2 signaling pathway in HPV-16 oncoprotein-induced HIF-1α, VEGF, and IL-8 expression and in vitro angiogenesis in NSCLC cells. Our results showed that HPV-16 E6 and HPV-16 E7 oncoproteins promoted the activation of ERK1/2 signaling pathway in A549 More >
