Hesperidin inhibits angiogenesis, induces apoptosis, and suppresses laryngeal cancer cell metastasis

Introduction: Laryngeal carcinoma is the most common malignant head-and-neck tumor. Due to the low survival rate and the inadequate response to chemotherapy, effective therapy remains a challenge. Objectives: Therefore, the identification of new therapeutic options that preserve the larynx is needed. Hesperidin (Hsp) is a nontoxic plant flavanone that has proven effective against cancer. Materials and methods: Hence, the current in vivo and in vitro study was conducted to determine whether Hsp might suppress metastasis of cancer larynx. Results: In an in vivo mouse metastasis model, Hsp suppressed metastasis of human Hep2 laryngeal cancer cells to the livers and lungs. In vitro assays, Hsp significantly inhibited angiopoietin 1 secretion (an angiogenic promotor) and increased annexin-V (an apoptotic indicator) in Hep2 cell culture at relatively low levels (10 μM). Conclusions: These studies suggest that Hsp deserves further investigation as a possible treatment option for laryngeal cancer.
