The pathogenetic mechanism of the mitochondrial tRNA(LeuUUR) gene mutation responsible for the MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) syndrome was investigated in transformants obtained by transfer of mitochondria from three genetically unrelated MELAS patients into human mitochondrial DNA (mtDNA)-less (rho(More)
In the present work, we demonstrate the possibility of using human blood platelets as mitochondrial donors for the repopulation of mtDNA-less (rho 0) cells. The noninvasive nature of platelet isolation, combined with the prolonged viability of platelet mitochondria and the simplicity and efficiency of the mitochondria-transfer procedure, has substantially(More)
BACKGROUND/AIMS Angiotensin II (Ang II) plays a critical role in the cardiac remodeling contributing to heart failure. However, the gene expression profiles induced by Ang II in the early stage of cardiac remodeling remain unknown. METHODS Wild-type male mice (C57BL/6 background, 10-weeek-old) were infused with Ang II (1500 ng/kg/min) for 7 days. Blood(More)
We have identified a novel Xenopus gene (xVAP019) encoding a DUF1208 domain containing protein. Using whole-mount in situ hybridization and RT-PCR, we found abundant xVAP019 maternal transcripts in the animal hemisphere during the cleavage stages and blastula stages. During gastrulation xVAP019 is differentially expressed with higher levels in the animal(More)
A severe mitochondrial protein synthesis defect in myoblasts from a patient with mitochondrial myopathy was transferred with myoblast mitochondria into two genetically unrelated mitochondrial DNA (mtDNA)-less human cell lines, pointing to an mtDNA alteration as being responsible and sufficient for causing the disease. The transfer of the defect correlated(More)
