Abstract

In this study, the endocytosis pathway of heparosan and its intracellular distribution were investigated in MCF-7 tumor cells and COS7 normal cells. The endocytosis inhibition and cellular probe location experiments showed that MCF-7 tumor cells took heparosan more efficiently and selectively than COS7 cells. The cellular uptake of heparosan was energy-dependent in both MCF-7 tumor cells and COS7 normal cells. Moreover, the major endocytosis pathway of heparosan into MCF-7 tumor cells was caveolin-mediated endocytosis and macropinocytosis. The internalized heparosan was mainly located in lysosomes of the cells.

[内吞途径和肝磷脂在细胞内的分布]。

本研究研究了肝磷脂聚糖在MCF-7肿瘤细胞和COS7正常细胞中的内吞途径及其在细胞内的分布。内吞抑制和细胞预定位实验表明，MCF-7肿瘤细胞比cos7细胞更有效和选择性地摄取肝磷脂糖。在MCF-7肿瘤细胞和COS7正常细胞中，肝磷脂的细胞摄取都是能量依赖性的。此外，肝素聚糖进入MCF-7肿瘤细胞的主要内吞途径是小窝蛋白介导的内吞作用和巨噬作用。内化肝磷脂主要位于细胞溶酶体中。
