    • Disclosed are a cell-permeable p53 recombinant protein in which a macromolecule transduction domain (MTD) is fused to the tumor suppressor p53, a polynucleotide encoding the same, a recombinant expression vector for producing the same, and a pharmaceutical composition of the treatment of cancer, comprising the same. Having high cell permeability, the p53 recombinant protein is effectively transduced into cells so that the tumor suppressor p53 can be translocated into cell nuclei. Within nuclei, p53 inhibits the formation of cyclin-CDK complexes to halt the cell cycle, thus suppressing excessive cell proliferation and inducing apoptosis of tumor cells. Therefore, the p53 recombinant protein can be useful as an anticancer agent in the treatment of various cancers.
    • 公开了一种细胞可渗透的p53重组蛋白,其中大分子转导结构域(MTD)与肿瘤抑制基因p53融合,编码该多核苷酸的多核苷酸,用于制备该多核苷酸的重组表达载体,以及治疗癌症的药物组合物 ,包括它们。 具有高细胞通透性,p53重组蛋白有效转导入细胞,使肿瘤抑制基因p53能够转位入细胞核。 在核内,p53抑制细胞周期蛋白CDK复合物的形成,以阻止细胞周期,从而抑制过量的细胞增殖并诱导肿瘤细胞凋亡。 因此,p53重组蛋白可用作治疗各种癌症的抗癌剂。

    • The present invention discloses cell permeable p18 recombinant proteins where a macromolecule transduction domain (MTD) is fused to a tumor suppressor p18. Also disclosed are polynucleotides encoding the cell permeable p18 recombinant proteins, an expression vector containing the cell permeable p18 recombinant protein, and a pharmaceutical composition for treating p18 deficiency or failure which contains the cell permeable p18 recombinant protein as an effective ingredient. The cell permeable p18 recombinant proteins of the present invention are capable of efficiently introducing a haploinsufficient tumor suppressor p18 into a cell, and thus, can activate cell signaling mechanisms involved in the activation of ATM and p53 that induce cell cycle arrest and apoptosis in response to DNA damage or oncogenic signals. Therefore, the cell permeable p18 recombinant proteins of the present invention can be effectively used as an anticancer agent.
    • 本发明公开了一种细胞渗透性p18重组蛋白,其中大分子转导结构域(MTD)与肿瘤抑制基因p18融合。 还公开了编码细胞可渗透性p18重组蛋白质的多核苷酸,含有细胞可渗透性p18重组蛋白质的表达载体和含有细胞可渗透性p18重组蛋白质作为有效成分的p18缺陷或失败的药物组合物。 本发明的细胞可渗透性p18重组蛋白能够有效地将不充分的单倍体肿瘤抑制基因p18引入细胞,从而可以激活参与ATM和p53激活的细胞信号传导机制,诱导细胞周期停滞和凋亡,以响应于 DNA损伤或致癌信号。 因此,本发明的细胞可渗透性p18重组蛋白质可以有效地用作抗癌剂。
