G cancer cell lines have substantial amounts of integrins: Roles of lipid rafts Koichi Furukawaa, Iori Kobayashi, Yoshiki Kodamab, Yuhsuke Ohmic, Satoko Yamamotod, Yuki Ohkawa, Mariko Kambe, Keiko Furukawaa Division of Biomedical Sciences, University of Life and Overall health Sciences, Chubu University, Nagoya, Japan; CD134/OX40 Proteins Accession bDepartment of Biomedical Sciences, University of Existence and Health and fitness Sciences, Chubu University, Kasugai, Japan; c Department of Biochemical Sciences, College of Daily life and Health and fitness Sciences, Chubu University, Kasugai, Japan; dKanazawa Healthcare University, Uchinada, Japanacyclodextrin resulted in marked reduction of exosomes and TSG101 in them. Summary/Conclusion: GD3 expression in cancer cells resulted in greater amounts of integrins in ECVs, suggesting that GD3 and integrins play roles during the malignant properties of cancers by forming molecular complexes on ECVs. Lipid rafts may possibly perform roles as web-sites to the complicated formation. Funding: Grants-in-aid from the Ministry of Training, Culture, Sports, Science and Technology of JapanIntroduction: Cancer-associated glycosphingolipids happen to be utilized as tumour markers and targets of cancer therapy. We now have analysed functions of gangliosides in cancers, and reported that cancer-associated gangliosides increase malignant properties of cells by forming complexes with several membrane molecules. Within this study, we’ve examined contents of extracellular vesicles (ECVs) secreted from ganglioside GD3expressing cancer cells to investigate roles of gangliosides within the regulation of ECVs, main for the induction of cancer microenvironments and metastasis. Approaches: GD3-positive cells likewise as GD3-negative handle cells had been established by transfection of GD3 synthase (ST8SIA1) cDNA into melanoma, glioma and compact cell lung cancer (SCLC) cell lines. ECVs have been collected from culture supernatants by repeated ultracentrifugation. Contents in ECVs had been analysed by Western blotting. Roles of lipid rafts have been analysed by treating cells with 1 mM methyl -cyclodextrin. Outcomes: In ECVs from GD3-positive melanoma cells, GD3 and ST8SIA1 mRNA have been detected in TLC and by RT-qPCR, respectively. In Western blotting, greater levels of integrin households were detected in ECVs from GD3-positive melanoma cells in contrast with those from GD3-negative cells. Equivalent increase of integrins was also located in glioma and SCLC cells. This was contrastive with integrin amounts in cell lysates from GD3-positive and adverse cells, exhibiting practically equivalent levels of integrins irrespective of GD3 expression. Notably in melanoma cells, levels of integrin 2, 1 and two showed marked maximize in GD3-positive cell-derived ECVs.
