Arsenic Trioxide and Carcinoma Cell Apoptosis Wang Jianhua, Xu Xiaoying, Wang Yuanliang (Bioengineering College at Chongqing University, Key Laboratory for Biomechanics and Tissue Engineering under Ministry of Education. Chongqing 400044） Abstract Arsenic trioxide, an inorganic compound of trivalent arsenic, is highly poisonous after acute exposure and carcinogenic following chronic exposure. Although arsenicals have long been used therapeutically, they have aroused increasing interest recently by the discovery that arsenic trioxide can induce apoptosis in the APL cell and other cancer cells. The article demonstrates the relative concepts of apoptosis and summarizes the effect of arsenic trioxide to the carcinoma, its possible principle included.
