    • 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.
    • 基本上由编码可抑制DNA合成的突变人IGFBP-3的核苷酸序列组成的分离或纯化的核酸分子可诱导细胞凋亡,既不与人胰岛素生长因子-I(IGF -I),也不是人胰岛素生长因子-II(IGF-II),并且在Y57包含突变; 包含其的载体,包含并表达其的细胞,任选地以载体的形式; 基本上由编码可抑制DNA合成的突变人IGFBP-3的氨基酸序列组成的分离或纯化的多肽分子可诱导细胞凋亡,既不与人IGF-I也不与人IGF-II结合,且在Y57包含突变; 包含该组合物的组合物; 以及诱导细胞凋亡的方法,该方法包括以足以诱导细胞凋亡的量向细胞施用核酸分子或多肽分子,随后在细胞中诱导凋亡。
