Here we report that human leukaemia cells carrying the translocation t(17;19) rapidly died by apoptosis when programmed to express a dominant-negative suppressor of the fusion protein E2A-HLF , indicating that the chimaeric oncoprotein probably affects cell survival rather than cell growth .
 ( DNA: t(17;19), None) , ( protein: E2A-HLF, None) , ( protein: chimaeric oncoprotein, None) , ( cell type: human leukaemia cells, None)
