| Outline of Final Research Achievements |
In the present studies we investigated the role of S1P signal in the cargo sorting into exosomes. As for the cargo molecule, we focused Met protein, which is known to play roles in the malignancy of several cancers. We cultured human melanoma B16-F10 cells in the absence or presence of sphingosine kinase (SK) inhibitor, HACPT for 1 day and quantitated the amount of Met in the exosomes. HACPT caused a significant decrease in Met amount compared with the control. However, knockdown of SK2 by a specific siRNA showed no significant changes in the amount of Met. We are now preparing SK2-nockout cells by a CRISPR/Cas system to investigate further the role of S1P signal in the Met sorting into exosomes.
