Angiogenesis is required in cancer, including gynecological cancers, for the growth of primary tumors and secondary metastases. Development anti-angiogenesis therapy cancers improvement its efficacy have been a major focus fundamental clinical research. However, survival benefits current anti-angiogenic agents, such as bevacizumab, patients with are modest. Therefore, better understanding angio...

introduction: exercise training increases skeletal muscle capillary density, but the molecular mechanisms of this process are not yet clear. the aim of the present study was to investigate the effect of acute long- term submaximal exercise on serum vascular endothelial growth factor (vegf) as the main angiogenic factor, and matrix metalloproteinases 2 and 9 ( mmp-2 and mmp-9), as the degrading ...

It is well known that the metabolic factors play an important role in the regulation of angiogenesis. Increased metabolic activity leads to decreased oxygen levels and causes tissue hypoxia. Hypoxia starts different signals to stimulate angiogenesis and promotes oxygen delivery to tissues. It has been suggested that released adenosine from hypoxic tissues plays a vital role in angiogenesis. ...

Angiogenesis, as the process of new vessel formation from pre-existing vessels is dependent on a delicate equilibrium between endogenous angiogenic and antiangiogenic factors. However, under pathological conditions, this tight regulation becomes lost which can result in the formation of the different diseases such as cancer. Angiogenesis is a complex process that includes many gene products tha...

Abstract Background Tumor angiogenesis, immunosuppression, and progression are all closely correlated with the tumor microenvironment (TME). Immune evasion is supported by both M2 phenotype tumor-associated macrophages (TAMs) vascular aberrations in TME. TME reprogramming a promising therapeutic approach for treating tumors. Anti-angiogenesis has power to control polarization of macrophages, pr...

This paper concerns a free boundary problem modeling tumor growth with angiogenesis and two time delays. The delays represent the taken for cells to undergo mitosis modify rate of cell loss because apoptosis, respectively. We study stability stationary solutions find that Hopf bifurcation occurs under some conditions, which extends results Xu. Furthermore, numerical simulations are performed in...

Background: Tumor cells need food and oxygen supply for growth and division. Therefore one of the most promising areas of cancer therapy focuses on using agents that inhibit tumor angiogenesis. Inhibition of angiogenesis prevents cell growth, division and metastasis. Previous studies showed that plasminogen related Protein-B has an anti-tumor activity in mice. This protein has a high level of h...
