objective(s): we previously reported a series of quinazoline derivatives as vascular-targeting anticancer agents. in this study, we investigated the mechanism underlying the anti-angiogenic activity of the quinazoline derivative compound 11d. materials and methods: we examined the effects of quinazoline derivative 11d on vascular endothelial growth factor receptor-2 (vegfr2) activation via vegf...

The Anti-angiogenic Activity of Phoenix dactylifera seeds methanol extract in vivo study Abstract: The aim of the study was to identify the antiangiogenic activity of Phoenix dactylifera seeds methanolic extract in vivo and the probable anti-angiogenic mechanism of action. The date seeds were extracted with methanol using cold method, the crude extract was tested on chick chorioallantoic ...

vascular endothelial growth factor (vegf-a) is one of the most important regulatory factors in pathological and physiological angiogenesis. alternative splicing is a complicated molecular process in vegf-a gene expression which adds complexity to vegf-a biology. among all vegf-a exons, alternative splicing of exon 8 is the key determinant of isoform switching from pro-angiogenic vegf-xxx to ant...

angiogenesis which is the recruitment of new blood vessels is a critical process in several chronic diseases and is an essential component of tumor or cancer progression. development of therapies aimed at inhibiting the angiogenesis, in combination with classical anti-cancer therapies, is among the most intensively studied approaches to treat the cancer. in this study the effect of chlordiazepo...

Animal studies showed that male gastric tissues respond more rapidly to Helicobacter pylori (H.pylori) infection but the possible mechanisms remained unclear. There is no data about gender specific activity of Androgen receptor (AR) as an independent unfavorable prognostic factor in gastric cancer and its interactions with H.pylori and angiogenesis in both genders. To compare the pathogenesis o...

this study aimed to investigate the anti-angiogenic activity of vitex agnus castus methanol extract in vivo. eggs were incubated for three days, small whole made on the fine pinpoint, next day the egg’s sac penetrated and a small frame was made in the shell. the window was resealed and eggs were returned to the incubator until day 10 of chick embryo development, 20 µl of 500mg/ml of the methano...
