Outline of Final Research Achievements |
We evaluated the mechanism of skin moisture maintaining system involving sphingoid bases. Sub-micromolar doses of sphingoid bases treatment, that doses do not damage cells, were treated on human keratinocyte cells. Caspase-14 mRNA level and protein level was upregulated dose-dependently on HaCaT cells. Furthermore, sphingoid bases-induced caspase-14 was involved of MAPK, especially JNK and p38. Affecting sphingoid bases to mouse skin resulted in upregulation of caspase-14, presuming that sphingoid bases could maintain skin barrier in vivo.
