Research Abstract

The system coordinating expressions of nuclear coded mitochondrial proteins was investigated by examination of the 5'-flanking region of the human mitochondrial ATP synthase beta-subunit gene.
At least two regions enhanced this promoter activity and at least one region repressed it. In one of the enhancing regions, a consensus sequence was found for the genes of other mitochondrial proteins such as those for cytochrome c1 and the pyruvate dehydrogenase alpha-subunit. This enhancing activity was independent of the orientation or location of the insert. Therefore, this is an enhancer that may be common to the nuclear genes of some mitochondrial proteins involved in energy transduction.
MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes) is a major heterogeneous mitochondrial diseases. For identifying a mutation in the mitochondrial gene, we isolated myogenic cell lines with distinctly different phenotypes from the same muscle tissue from a patient with MELAS : one was respiratory-deficient and the other was apparently normal.
Only one A to G nucleotide transition at nucleotide number 3.243 in the tRNA-Leu (UUR) gene was found in whole mitochondrial DNA of the respiratory-deficient cells compared with that of the normal cells. This mutation was also found in 8 patients from unrelated families with MELAS in a heteroplasmic manner, but not in control individuals. Therefore, the single point mutation causes the functional abnormality in respiratory chain of mitochondria.
