Abstract

Aging is a complex process in which the structure and function of various tissues and organs gradually decline with age, and ovarian aging affects the reproductive capacity of females and induces age-related diseases. Resveratrol, a natural polyphenol compound, extends the life span and has a protective effect on the ovaries of vertebrates. However, the effects and underlying mechanisms of resveratrol delaying ovarian aging are unclear. In this study, using an annual fish Nothobranchius guentheri, we demonstrated that senescence-associated-beta-galactosidase (SA-β-gal) activity and lipofuscin accumulation increased with age in the ovaries, and resveratrol reversed this phenomenon. Resveratrol increased proliferating cell nuclear antigen (PCNA) expression and the oocyte proportions of the primary growth stage, cortical alveolus stage and vitellogenesis stage, and decreased the number of atretic follicles in the ovaries of 6-, 9-, and 12-month-old fish. Moreover, the expression of SIRT1 and NRF2 decreased and the levels of NF-κB, pro-inflammatory cytokines IL-1β, TNF-α, and IL-8 and endoplasmic reticulum (ER) stress markers GRP78 and CHOP increased with aging, while resveratrol up-regulated SIRT1 and NRF2 expression and down-regulated NF-κB, IL-1β, TNF-α, IL-8, GRP78, and CHOP levels in the ovaries of 6- and 9-month-old fish. In HEK293T cells, knockdown SIRT1 decreased NRF2 and increased NF-κB p65, pro-inflammatory cytokines (IL-1β and TNF-α), and ER stress marker GRP78 expression markedly. Silencing SIRT1 and then treating the cells with resveratrol significantly reversed the phenomenon. Collectively, resveratrol might activate SIRT1/NRF2 to reduce inflammation and ER stress, and finally delay ovarian aging in a short-lived fish. This study highlights the protective effect and mechanism of resveratrol on ovarian aging.

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.
