Head and neck cancer is the sixth most common cancer worldwide. Dihydroartemisinin (DHA), a semi synthetic derivative of artemisinin, exhibits a wide range of biological roles including a highly efficient and specific anti-tumor activity. Here, we aimed to examine the effect of DHA on head and neck carcinoma cells and elucidate the potential mechanisms. We used five head and neck carcinoma cell lines and two non-tumorigenic normal epithelial cell lines to achieve our goals. Cells were exposed to DHA and subjected to cellular activity assays including viability, cell cycle analysis, cell death, and angiogenic phenotype. Our results show that DHA causes cell cycle arrest which is mediated through Forkhead box protein M1 (FOXM1). We also demonstrate that DHA induces ferroptosis and apoptosis in head and neck carcinoma cells. Lastly, our results show that DHA alters the angiogenic phenotype of cancer cells by reducing the expression of angiogenic factors and the ability of cancer cells to support endothelial cell tubule formation. Our study suggests that DHA specifically causes head and neck cancer cell death through contribution from both ferroptosis and apoptosis. DHA may represent an effective strategy in head and neck cancer treatment. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
