background: marine natural products contain a wide range of bioactive compounds with therapeutic properties that have revealed crucial properties in the treatment of some diseases. some of these compounds have recently received considerable attention for drug discovery. in this study we examined the anti-angiogenic effect of saponin isolated from holothuria leucospilota (sea cucumber) through e...

Background and aim: Lichen planus (LP) is a chronic inflammatory disease with an uncertain pathogenicity. Recent reports have revealed that angiogenesis is effective in the pathogenesis and biologic behavior of lesions. Considering the limitations of the studies related to angiogenesis in oral LP (OLP) and the controversial results, the present study aimed to compare the expression of vascular ...

Objective(s): Previous study has indicated that triiodothyronine (T3) facilitated cartilage degeneration in osteoarthritis (OA). This study aimed to investigate the effects of T3 on angiogenesis-related factor expression in human osteoblasts of OA subchondral bone.Materials and Methods: The subchondral bone specimens were obtained from O...

Specific proteolytic cleavages turn on, modify, or off the activity of vascular endothelial growth factors (VEGFs). Proteolysis is most prominent among lymph­angiogenic VEGF-C and VEGF-D, which are synthesized as precursors that need to undergo enzymatic removal their C- N-terminal propeptides before they can activate receptors. At least five different proteases mediate activating cleavage VEGF...

Background: Several studies have shown that leukemia inhibitory factor (LIF) is one of the most important cytokinesparticipating in the process of embryo implantation and pregnancy, while, the role of this factor on vascular endothelialfactor-A (VEGF-A), as one of the most important angiogenic factor, has not been fully investigated yet. The aimof this study was to evaluate th...

tumor cells are dependent on angiogenesis to obtain oxygen and nutrients and also development of their new vascular network. vegf as an important stimulator of angiogenesis and endostatin as an inhibitor play a fundamental role in this process. this study was designed to investigate the effect of six weeks of resistance training on tumor tissue vegf andendostatin in mice with breast cancer. for...

background: the vegf is essential in the process of tissue remodeling and angiogenesis. limited data is available on the expression and regulation of vegf and its receptors in the human endometrium. the aim of this study was evaluation of expression patterns of vegf and flk-1 in human endometrium during the menstrual cycle. methods: sixty paraffin-embedded blocks of endometrial tissues from the...

Objective(s): Blocking of vascular endothelial growth factor (VEGF) plays a pivotal role in inhibition of metastasis and is a target for development of anti-angiogenic agents. In this study, a peptide-based vaccine was designed and its potential for induction of humoral immune responses, generation of neutralizing antibodies, inhibition of tumor growth and metastasis w...

human bone marrow derived mesenchymal stem cells (hbmscs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. in this study, the differentiation of hbmscs into endothelial like-cells was induced in presence of vascular endothelial growth factor (vegf) and insulin-like growth factor (igf-1). the differentiated endothelial cells were exam...
