Native mitochondrial creatine kinase forms octameric structures. I. Isolation of two interconvertible mitochondrial creatine kinase forms, dimeric and octameric mitochondrial creatine kinase: characterization, localization, and structure-function relationships.

The mitochondrial isoform of creatine kinase (Mi-CK, EC 2.7.3.2) purified to homogeneity from chicken cardiac muscle by the mild and efficient technique described in this article was greater than or equal to 99.5% pure and consisted of greater than or equal to 95% of a distinct, octameric Mi-CK protein species, with a Mr of 364,000 +/- 30,000 and an apparent subunit Mr of 42,000. The remaining ...

Genetics of Mitochondrial Myopathies

Pearson syndrome. Clinical spectrum of mitochondrial disorders is broad, so consensus diagnostic criteria for mitochondrial disorders have been proposed for children and adults. Sequence map of human mitochondrial genome with its normal and patho­ genic variants is publicly available. In this review, we will discuss genetic features of mitochondrial myopathies as well as their key findings. Rep...

Mitochondrial myopathies: developments in treatment.

PURPOSE OF REVIEW Treatment options for mitochondrial myopathies remain limited despite rapid advances in the understanding of the molecular basis of these conditions. Existing therapies continue to be evaluated and novel treatment strategies are starting to appear on the horizon. RECENT FINDINGS Exercise training continues to show promise as a method of improving exercise tolerance and enhan...

Mitochondrial myopathies: defects in mitochondrial metabolism in human skeletal muscle.

An uncommon but increasingly diagnosed clinical situation in humans is mitochondrial myopathy, a condition in which muscle function is impaired by defective mitochondrial metabolism in the generation of energy for muscle contraction. It is also now clear that abnormalities of mitochondrial function are not limited to muscle, but may also underlie multisystem disease, in which other tissues are ...

Apoptosis in mitochondrial myopathies is linked to mitochondrial proliferation.

Increased susceptibility to apoptosis has been shown in many models of mitochondrial defects but its relevance to human diseases is still discussed. We addressed the presence of apoptosis in muscle from patients with mitochondrial DNA (mtDNA) disorders. Taking advantage of the mosaic pattern of muscle morphological anomalies associated with heteroplasmic mtDNA alterations, we have used an in si...
