Increased tube formation and up-regulation of FGFR3 mRNA expression in microvascular endothelial cell by exosomes derived from SW480-7.
Introduction: Extracellular vesicles (exosome-like vesicles) are small membrane vesicles ranging from 20-200nm in size that are released by various cells into the extracellular space. These extracellular vesicles play a major role in cell-to-cell communication and contain materials, such as proteins, mRNAs, microRNAs (miRNAs) and long non-coding RNAs (lncRNAs). The effect of exosomes derived from an invasive colon cancer cell line on angiogenesis is unclear. Hence, the aim of this study is to investigate the effect of exosomes derived from an invasive colon cancer cell line on angiogenesis of endothelial cells.
Materials and methods: In the present study, the exosomes from the cell culture supernatants of an invasive colon cancer cell line SW480-7 were characterised. The effect on tube formation and expression of angiogenic genes in a microvascular endothelial cell, telomerase-immortalised microvascular endothelial cell (TIME) was examined after co-cultured with exosomes secreted from SW480-7.
Results: Zetasizer result showed average diameter of exosomes derived from SW480-7 was 246.2 nm and morphological analysis showed the size of majority of exosomes were less than 200 nm. Results showed that exosomes derived from SW480-7 increased tube formation and up-regulated FGFR3 mRNA expression in TIME.
Conclusion: Our findings suggest that exosomes derived from SW480-7 increased tube formation and up-regulated expression of FGFR3 mRNA in TIME.
期刊介绍：
The Malaysian Journal of Pathology is the official journal of the College of Pathologists, Academy of Medicine Malaysia. The primary purpose of The Journal is to publish the results of study and research in Pathology, especially those that have particular relevance to human disease occurring in Malaysia and other countries in this region. The term PATHOLOGY will be interpreted in its broadest sense to include Chemical Pathology, Cytology, Experimental Pathology, Forensic Pathology, Haematology, Histopathology, Immunology, Medical Microbiology and Parasitology. The Journal aims to bring under one cover publications of regional interest embracing the various sub-specialities of Pathology. It is expected that the articles published would be of value not only to pathologists, but also to medical practitioners in search of a scientific basis for the problems encountered in their practice, and to those with an interest in diseases which occur in the tropics.
