Abstract

Defects of the mitochondrial genome cause a wide variety of clinical disorders. Except for rare cases where surgery or transplant is indicated, there is no effective treatment for patients. Genetic-based therapies are consequently being considered. On account of the difficulties associated with mitochondrial (mt) transfection, alternative approaches whereby mitochondrial genes can be engineered and introduced into the nucleus (allotopic expression) are being attempted with some success, at least in cultured cells. Defects in the activities of multi-subunit complexes of the oxidative phosphorylation apparatus have been circumvented by the targeted expression of simple single subunit enzymes from other species (xenotopic expression). Although far from the clinic, these approaches show promise. Similarly, nuclear transfection with genes encoding restriction endonucleases or sequence-specific zinc finger-binding proteins destined for mitochondria has also proved successful in targeting mtDNA-borne pathogenic mutations. This is particularly important, as mutated mtDNA is often found in cells that also contain normal copies of the genome, a situation termed heteroplasmy. Shifting the levels of heteroplasmy towards the normal mtDNA has become the goal of a variety of invasive and non-invasive methods, which are also highlighted in this review.

  • CMCO:PNA hybrid molecules have been successfully targeted and imported into mitochondria in whole cells.

    “Molecules with greater polarity have since been designed (cell membrane crossing oligomers, CMCOs), and CMCO:PNA hybrid molecules have been successfully targeted and imported into mitochondria in whole cells [235].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
