    • PURPOSE: A pharmaceutical composition for cancer prevention or treatment including endocytic motif and protein introduction domain is provided to specifically inhibit endocytosis of c-Met by polypeptide in order to effectively inhibits HGF/c-Met signal transmission path and inhibit transition, infiltration, vascularization and growth of cancer. CONSTITUTION: A pharmaceutical composition for cancer prevention or treatment includes endocytic motif which is represented as amino acid sequence having the sequence number 1(SEQ ID NO:1). The motif is imported inside cells by clathrin mediated endocytosis. The motif is c-Met, phosphorylated c-Met, or c-Met combined with HGF(hepatocyte growth factor). The motif inhibits self - phosphorylation of c-Met by HGF. The Pharmaceutical composition for preventing or treating cancers includes motif as an active ingredient. A fused polypeptide is endocytotic motif-C terminal represented by equation 1: N-terminal-protein transduction domain-amino acid sequence having the sequence number 1 or endocytic motif - protein transduction domain -C terminal represented by equation 2: N- terminal-amino acid sequence having the sequence number 1. The protein transduction domain is Tat of HIV(human immunodeficiency virus); VP22 of HSP(herpes simplex virus); Antp of pomace fly; Mph-1; Sim-2; R7; Pep-1; or Pep-2.
    • 目的:提供一种用于癌症预防或治疗的药物组合物,包括内吞基序和蛋白质引入结构域,以特异性抑制多肽对c-Met的内吞作用,以有效抑制HGF / c-Met信号传递途径并抑制转化,浸润,血管化和 癌症的增长。 构成:用于癌症预防或治疗的药物组合物包括表示为具有序列号1(SEQ ID NO:1)的氨基酸序列的内吞基序。 该基序通过网格蛋白介导的内吞作用进入细胞内。 该基序是c-Met,磷酸化c-Met或c-Met与HGF(肝细胞生长因子)组合。 该基序抑制HGF自身磷酸化c-Met。 用于预防或治疗癌症的药物组合物包括作为活性成分的基序。 融合多肽是由等式1表示的内吞基序-C末端:具有序列号1的N末端蛋白转导结构域 - 氨基酸序列或由等式2表示的内吞基序 - 蛋白转导结构域-C末端:N-末端氨基 具有序列号1的酸序列。蛋白转导结构域是HIV的Tat(人免疫缺陷病毒); HSP(单纯疱疹病毒)VP22; 荞麦飞 MPH-1; SIM-2; R7; PEP-1; 或Pep-2。
