7,8-dihydroxyflavone (7,8-DHF), which is a member of the flavonoid family, is a selective tyrosine kinase receptor B (TrkB) agonist that has neurotrophic effects in various neurological diseases such as ischemic stroke and Parkinson’s disease [3]. In this study, we assessed the angiogeneic effect of 7,8-DHF in endothelial cells derived from resistance vessel of the brain. Angiogenesis by 7,8-DHF is an important factor that helps prevent and treat various ischemic diseases. In this study, we found that rat RV cells used in the experiment possess the TrkB receptor. Our data also demonstrates that 7,8-DHF is able to stimulate cell proliferation in RV cells, suggesting that 7,8-DHF is capable of inducing angiogenesis. The 7,8-DHF activates the TrkB receptor which then leads to cell proliferation. In our study we also showed the effects of 7,8-DHF in the presence of the TrkB inhibitor cyclotraxin-B. Addition of cyclotraxin-B blocked the TrkB receptor and counteracted the effects of 7,8-DHF. Cell proliferation occurs in RV cells with the addition of 7,8-DHF, but this proliferation is inhibited by cyclotraxin-B.
