Artesunate reduces chicken chorioallantoic membrane neovascularisation and exhibits antiangiogenic and apoptotic activity on human microvascular dermal endothelial cell.

abstract：:Malignant tumors remain a major health burden throughout the world, and effective therapeutic strategies are urgently needed. Combining gene therapy with chemotherapeutics in a single delivery system is more effective than co-treatment of cancer with individual delivery systems carrying either gene or drug. In this st...
