Outline of Final Research Achievements

Ceramides are the key intermediates involved in sphingolipid metabolism. Development of sensitive and specific methods is required to quantify the intra- and extracellular ceramide levels and to understand the physiological role of ceramides.
The combination of liquid chromatography with mass spectrometry can serve as a powerful tool for analyzing complex intact ceramides. We developed a new method using mass spectrometer coupled with ultra performance liquid chromatography (UPLC) for the rapid and simultaneous quantification of ceramides such as C16-, C18-, C20-, C22-, C24-, C24:1-, and C26-ceramide. This method was successfully applied to monitor ceramides in the subcellular fraction obtained from cultured cells. In conclusion, our new method was validated for ceramide analysis, and this can be used in a wide range of clinical applications and to perform biological studies for discerning the role(s) of sphingolipid metabolites.
