Abstract

The ovarian hormones progesterone and estrogen have well-established neurotrophic and neuroprotective effects supporting both reproductive function and cognitive health. More recently, it has been recognized that these steroids also regulate metabolic functions sustaining the energetic demands of this neuronal activation. Underlying this metabolic control is an interpretation of signals from diverse environmental sources integrated by receptor-mediated responses converging upon mitochondrial function. In this study, to determine the effects of progesterone (P4) and 17β-estradiol (E2) on metabolic control via mitochondrial function, ovariectomized rats were treated with P4, E2, or E2 plus P4, and whole-brain mitochondria were isolated for functional assessment. Brain mitochondria from hormone-treated rats displayed enhanced functional efficiency and increased metabolic rates. The hormone-treated mitochondria exhibited increased respiratory function coupled to increased expression and activity of the electron transport chain complex IV (cytochrome c oxidase). This increased respiratory activity was coupled with a decreased rate of reactive oxygen leak and reduced lipid peroxidation representing a systematic enhancement of brain mitochondrial efficiency. As such, ovarian hormone replacement induces mitochondrial alterations in the central nervous system supporting efficient and balanced bioenergetics reducing oxidative stress and attenuating endogenous oxidative damage.

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.
