| Outline of Final Research Achievements |
By screening of Hdac inhibitory molecules, we found that Brazilian propolis extract (BPE) showed Hdac inhibitory effect. BPE also protected neuronal cells from endoplasmic reticulum stress induced cell death, which causes most of the neurodegenerative diseases.
We studied the Hdac modulating effects of branched fatty acid phytanic acid (PA), which is a metabolic intermediate of chlorophyll in beef and dairy products. Although generally fatty acids were reported to show Hdac inhibitory effects, PA showed Hadc activating effect. And PA induced neuronal cell death. During this study, we found that Hdac modulation associated with mitochondrial activity in neuronal cells. Our data suggests that the mitochondrial activations might be involved in the neuroprotective functions of Hdac inhibitory molecules.
