Attempts to understand the mechanisms of mitochondrial diseases: the reverse genetics of mouse models for mitochondrial disease

Ishikawa, Kaori, Nakada, Kazuto·2021·Biochimica et Biophysica Acta (BBA) - General Subjects

Abstract

Background Mitochondrial disease is a general term for a disease caused by a decline in mitochondrial function. The pathology of this disease is extremely diverse and complex, and the mechanism of its pathogenesis is still unknown. Using mouse models that develop the disease via the same processes as in humans is the easiest path to understanding the underlying mechanism. However, creating a mouse model is extremely difficult due to the lack of technologies that enable editing of mitochondrial DNA (mtDNA).Scope of review This paper outlines the complex pathogenesis of mitochondrial disease, and the difficulties in producing relevant mouse models. Then, the paper provides a detailed discussion on several mice created with mutations in mtDNA. The paper also introduces the pathology of mouse models with mutations including knockouts of nuclear genes that directly affect mitochondrial function.Major conclusions Several mice with mtDNA mutations and those with nuclear DNA mutations have been established. Although these models help elucidate the pathological mechanism of mitochondrial disease, they lack sufficient diversity to enable a complete understanding. Considering the variety of factors that affect the cause and mechanism of mitochondrial disease, it is necessary to account for this background diversity in mouse models as well.General significance Mouse models are indispensable for understanding the pathological mechanism of mitochondrial disease, as well as for searching new treatments. There is a need for the creation and examination of mouse models with more diverse mutations and altered nuclear backgrounds and breeding environments.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Mitochondrial diseases are caused by genetic mutations in mitochondrial or nuclear DNA that affect the function of the mitochondrial respiratory chain, leading to defective oxidative phosphorylation.

    “Mitochondrial diseases are caused by genetic mutations in mitochondrial or nuclear DNA that affect the function of the mitochondrial respiratory chain, thereby leading to defective oxidative phosphorylation (Ishikawa and Nakada, 2021; Parikh et al., 2015; Thorburn, 2004).”

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.
