摘要
瘦素作为一种多肽激素,具有广泛的生物学效应,其主要功能是与下丘脑瘦素受体(OBR)结合,调节食欲和能量代谢。近年研究发现,瘦素对肿瘤的形成和发展具有重要的调节作用。肿瘤细胞增生、黏着、侵袭及癌组织新生血管形成是肿瘤发生、发展的基本过程。瘦素通过多条途径参与对该过程中许多细胞及细胞因子调节的作用,影响癌灶微环境的免疫功能,促使肿瘤细胞增生、浸润和新生血管的形成,因而与肿瘤关系密切。就近年的相关研究进展进行综述。
Leptin as a polypeptide has a wide range of biologic effects, which can regulate appetite and energy metabolism common with leptin receptor. Recent studies found that leptin was related with tumor formation and development, which contribute to tumor progression by increasing angiogenesis, stimulates cell proliferation, adhesion and invasion through multiple channels.
