Research Abstract |
Mitochondrial encephalplathy, myopathy, lactic acidosis and strokelike episodes (MELAS) syndrome is characterized by a mitochondrial DNA (mtDNA) mutation (A3243G) and mitochondrial angiopathy in the brain. To investigate the pathogenic mechanism for mitochondrial angiopathy, we tried to construct cybrids that carry the MELAS mutation and were derived from human brain vessel endothelial cells. First, we determined the optimal concentration of ethidium bromide (EtBr) to reduce or remove mtDNA from the blood vessel endothelial cells. We then introduced the platelet mitochondria from MELAS patients into the blood vessel endothelial cells lacking mtDNA. Cybrids carrying the mtDNA mutation were hard to survive. We should further investigate the optimal media condition to get cybrids survived.
