Progresses on antitumor effect of snake venom active components

Many snake venoms contain complex mixtures of pharmacologically important molecules, some of which show potential therapeutic value in the treatment of cancer and other human disorders. In this review, we mainly reports the effects of snake venom active components, such as disintegrins and lectins in paralyzing cancer cells, blocking on cell migration, interaction with integrins, inhibition of tumor dissemination and angiogenesis. The advanced researches on the snake venom's apoptosis-inducing components on tumors are also introduced.
