With many desirable features, such as being more effective and having multiple effects, antiangiogenesis has become one of the promising cancer treatments. The aim of this study was to design and synthesize a new targeted bioresponsive nanosystem with antiangiogenesis properties. The mUPR@Ru(POP) nanosystem was constructed by the polymerization of Ulva lactuca polysaccharide and N-isopropyl acr...

Drugs that target the tumor vasculature and inhibit angiogenesis are widely used for cancer treatment. Individual tumors show large differences in vascularity, but it is uncertain how these differences affect responsiveness to antiangiogenesis. We investigated this question using two closely related prostate cancer models that differ markedly in tumor vascularity: PC3, which has very low vascul...

The transcription factors STAT1 and STAT3 appear to play opposite roles in tumorigenesis. While STAT3 promotes cell survival/proliferation, motility and immune tolerance and is considered as an oncogene, STAT1 mostly triggers anti-proliferative and pro-apoptotic responses while enhancing anti-tumor immunity. Despite being activated downstream of common cytokine and growth factor receptors, thei...

Based on the concept that solid tumors cannot grow without the generation of new blood vessels, there is growing interest in the use of antiangiogenesis agents to inhibit tumor growth. This review summarizes the concepts of using gene transfer vectors to provide high concentration of antiangiogenic proteins within an organ. While there are many challenges that must be met before antiangiogenesi...

Endostatin is a potent endogenous angiogenesis inhibitor that induces regression of tumors in mice. Neither an extracellular receptor for endostatin nor intracellular signals that result in the regression of tumor vascular beds have been identified. We demonstrate that endostatin, but not angiostatin, at comparable concentrations to those used in in vivo animal trials, rapidly down-regulates ma...

Angiogenesis, the growth of new capillary blood vessels, is a central regulator of cancer growth, and a validated target for cancer therapy. The antiangiogenic agents in clinical use target one or more cellular pathways involved in the cascade of vascular growth. In haematological malignancies, angiogenesis occurs within a bone marrow ecosystem comprised of closely apposed malignant cells, endo...

Angiogenesis is a hallmark of tumor development and metastasis and is now a validated target for cancer treatment. However, the survival benefits of antiangiogenic drugs have thus far been rather modest, stimulating interest in developing more effective ways to combine antiangiogenic drugs with established chemotherapies. This review discusses recent progress and emerging challenges in this fie...

Abstract Acute Myeloid Leukemia (AML) is the abnormal differentiation of hematopoietic stem cells in bone marrow into malignant blasts. The leukemic environment plays an important role during disease progression, by shaping immune landscape interacting with these Mounting evidence suggests neutrophils are complicit within tumors enhancing tumorigenesis and immunosuppression; however, little kno...
