Can dying cells from a patient's tumor serve as an anticancer vaccine? To explore this
possibility, Pierrefite-Carle et al. (p. 2014) created "suicide"
tumor cells by introducing the Escherichia coli cytosine deaminase gene into cells of a rat
colon carcinoma cell line. Exposure of the modified cells to the nontoxic compound
5-fluorocytosine causes them to die because the bacterial gene product converts it into the
cytotoxic agent 5-fluorouracil. When the modified cells are injected into the livers of syngeneic
animals, they form single experimental "suicide tumors." As expected, when
animals bearing suicide tumors were treated with
