    Abstract: An isolated or purified nucleic acid molecule consisting essentially of a nucleotide sequence encoding a mutant human IGFBP-3, which can inhibit DNA synthesis, can induce apoptosis, binds to neither human insulin growth factor-I (IGF-I), nor human insulin growth factor-II (IGF-II), and comprises a mutation at Y57; a vector comprising the same, a cell comprising and expressing the same, optionally in the form of a vector; an isolated or purified polypeptide molecule consisting essentially of an amino acid sequence encoding a mutant human IGFBP-3, which can inhibit DNA synthesis, can induce apoptosis, binds to neither human IGF-I nor human IGF-II and comprises a mutation at Y57; a composition comprising the same; and a method of inducing apoptosis in a cell, which method comprises administering to the cell the nucleic acid molecule or polypeptide molecule, in an amount sufficient to induce apoptosis in the cell, whereupon apoptosis is induced in the cell.
