Abstract excerpt
The present study examined differentiation-inducing activity by various tumor-necrosis-factor(TNF) mutants against the human leukemic cell lines HL-60 and U-937. Mutant TNF 471, from which 7 N-terminal amino acids of native TNF were deleted and Pro8, Ser9 and Asp10 were replaced by Arg, Lys and Arg, possessed the highest activity among the TNF mutants, and its activity was 120-fold that of native TNF. The various...
