Angiogenesis, the process by which new capillary blood vessels or lymphatic vessels grow from pre-existing vessel and elongates to form a new vessel, is essential for growth and metastasis of many solid tumors [65]. TECs differentiation, migration and proliferation account for angiogenesis. IL-8 and VEGF, Members of the angiogenic factor family, play important roles in TECs development and angiogenesis [66]. Lactic acid is an energy-rich metabolite capable of serving as a precursor for ATP
