    • The present invention relates to a novel function of lysyl tRNA synthetase (KRS) which enhances tumor cell migration and affects cancer metastasis via KRS's interaction with laminin receptor (67LR) by its translocation to membrane. More particularly, the present invention relates to a method for modulating cancer metastasis or migration, which comprises regulating intracellular levels of KRS; a composition for preventing or treating cancer; use of expression vector for inhibiting the expression of KRS; a method for preventing or treating cancer; use of an agent for inhibiting an activity of KRS; a method for screening an agent which modulates cancer metastasis or migration; and a method for screening an agent which inhibits the interaction of KRS with 67LR, by said novel function. Thus, KRS can modulate cancer metastasis or migration and furthermore, can modulate intra-cellular metabolism related to 67LR. The interaction between KRS and 67LR can be used effectively in treating, preventing and/or diagnosing of various diseases or disorders related to the interaction.
    • 本发明涉及赖氨酰tRNA合成酶(KRS)的新功能,其通过Kis与层粘连蛋白受体(67LR)的相互作用通过其迁移到膜来增强肿瘤细胞迁移并影响癌症转移。 更具体地,本发明涉及一种调节癌症转移或迁移的方法,其包括调节细胞内KRS水平; 用于预防或治疗癌症的组合物; 使用表达载体抑制KRS的表达; 预防或治疗癌症的方法; 使用抑制KRS活性的药剂; 筛选调节癌症转移或迁移的药物的方法; 以及通过所述新功能筛选抑制KRS与67LR的相互作用的药剂的方法。 因此,KRS可以调节癌症转移或迁移,此外,可以调节与67LR相关的细胞内代谢。 KRS和67LR之间的相互作用可以有效地用于治疗,预防和/或诊断与相互作用相关的各种疾病或病症。
