background: for xenograft models of triple-negative breast cancer (tnbc) to be valuable in development of molecularly-targeted drugs, careful characterization is essential to their validation. the present study aimed to validate the tnbc xenograft model with a specific focus on angiogenesis. methods : twelve tnbc xenograft tumors and 12 human breast cancer tumors (htnbc) were included in this s...

Background: Deltamethrin (DTM) is a pyrethroid derivative, which is the most potent products of Type 2 insecticides and acts by delaying the closure of sodium channels. Estrogen as a vascular growth factor on ovarian tissue plays an essential impact further to its involvement in follicular growth. On the other hand, the role of angiogenesis on ovarian tissue in inhibiting the apoptotic provoker...

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...

conclusions the obtained results indicate that rsm is an effective method for the optimization of culture conditions for hes gene expression in e. coli. results a maximum rhes mrna level of 376.16% was obtained under the following conditions: 0.6 mm iptg, 7 hours post-induction time, and 0.9 cell density before induction. the level of rhes mrna was significantly correlated with post-induction t...

oral lichen planus is a chronic inflammatory immune-mediated disease. icam-1 and vcam-1 are vascular adhesion molecules that their receptors are located on endothelial cells and leukocytes. the aim of this study is the immunohistochemical evaluation of vcam1 and icam1 in oral lichen planus and to compare these two markers with normal mucosa for evaluation of angiogenesis. this descriptive-analy...

Background: Peripheral arterial disease (PAD) can severely compromise limb vitality and function. Angiogenesis plays an important role in healing of ischemic lesions. Radiolabeled RGD (Arg-Gly-Asp) peptides specifically targeting αvβ3 integrin are promising tracers for imaging angiogenesis. In this study, we investigated the application a one-step labeled evaluation angiogenesis therapy respons...

Introduction Over the last decades, considerable levels of electromagnetic fields (EMFs) have been characterized in the living environment. Recent epidemiological studies on occupational and residential exposure to EMF have shown that 50/60 Hz fields, known as extremely low frequencies (ELF), have various biological effects, such as angiogenesis. This study aimed to investigate the effect of en...
