| Outline of Final Research Achievements |
We previously reported that phospholipid scramblase 3 (PLCSR3), stably expressed in human embryonic kidney (HEK) 293 cells, is secreted from the cells extracellularly as membrane vesicles (exosomes). In the present study, we clarified that PLSCR3 is expressed in mouse preadipocytic 3T3-L1 cells and that the amount of intracellular PLSCR3 decreased during differentiation but that of extracellularly secreted protein increased. Overexpression of PLSCR3 in 3T3-L1 cells suppressed adipocytic differentiation and transcription factor induction at the late stage. PLSCR3 was suggested to act as a negative regulator of adipogenesis.
