| 英文摘要 | Type-I ribosome-inactivating protein-trichosanthin (TCS) exhibits selective cytotoxicity toward different types of cells. It is believed that the cytotoxicity results from the inhibition of ribosomes to decrease protein synthesis, thereby indicating that there are specific mechanisms for TCS entry into target cells to reach the ribosomes. Low-density lipoprotein (LDL) receptor-related protein 1 (LRP1) is a large scavenger receptor that is responsible for the binding and endocytosis of diverse biological ligands on the cell surface. In this study, we demonstrated that 2 choriocarcinoma cell lines can significantly bind and internalize TCS. In contrast, Hela cell line displayed no obvious TCS binding and endocytosis. Furthermore LRP1 gene silencing in JAR and BeWo cell lines blocked TCS binding: TCS could also interact with LRP1.The results of our study established that LRP1 was a major receptor for phagocytosis of TCS in JAR and BeWo cell lines and might be the molecular basis of TCS abortificient and anti-choriocarcinoma activity.
