Cardiolipin Remodeling in the Heart

Sparagna, Genevieve C, Lesnefsky, Edward J·2009·Journal of Cardiovascular Pharmacology

Abstract

Cardiolipin (CL) is a mitochondrial phospholipid that fundamentally contributes to the function of many proteins in the inner mitochondrial membrane, where it is actively involved in the integrity and flux of the electron transport chain. In the heart, functional CL is linoleic acid rich, and the loss of linoleic acid content is associated with cardiac disorders including ischemia and reperfusion, heart failure, and diabetes, as well as the X-linked recessive disease, Barth syndrome. To attain its high levels of linoleic acid, newly synthesized CL must initially undergo remodeling. CL modification and depletion by pathological processes may represent a failure of this remodeling pathway or activation of an alternative "pathological remodeling" pathway that causes the substitution of higher molecular weight, polyunsaturated fatty acyl side chains such as arachidonic or docosahexaenoic acid onto CL. This remodeling may occur in response to the alteration of CL by oxidative mechanisms, but the substituted side chains can also provoke further oxidation of CL. It is increasingly thought that cardiac pathology may result, at least partially, due to changes in CL resulting from the pathological remodeling process. Dietary interventions may restore CL to its linoleic acid-rich form and improve cardiac function by redirecting the remodeling process.

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.
