Outline of Final Research Achievements |
Glucosylceramides and their sphingoid bases were purified from various food materials and the effect of these sphingolipids on the mRNA expression of the transporter of various nutrients was investigated. The levels of mRNA of transporters related to minerals, such as calcium and magnesium, were significantly increased by the treatment of glucosylceramide and sphingoid base from plants and fungi. Futhermore, These sphingolipids facilitated the dimerization of CTR1 protein, which is involved in the incorporation of copper, and increased the contents of glycosylated iron transporter DMT-1 protein.
