1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe global trend of delayed childbearing underscores age-related fertility decline as a critical health issue, driven primarily by the loss of ovarian follicles. Mitochondrial dysfunction and oxidative stress are key pathological factors in this process. SS31, a mitochondria-targeting antioxidant peptide, holds potential for mitigating reproductive aging, though its precise mechanisms in ovarian aging require further elucidation.

methodsThis preclinical study utilized a naturally aged (10-month-old) female ICR mouse model and a D-galactose-induced senescence model in human KGN granulosa cells. We investigated the protective effects and mechanism of action of SS31 on the ovarian follicle unit.

resultsSS31 specifically localized to granulosa cell mitochondria. Treatment alleviated oxidative damage-induced apoptosis, improved mitochondrial function (including membrane potential and ATP production), and ameliorated senescence-associated impairment of the granulosa cell-oocyte unit. Mechanistically, SS31 enhanced cellular antioxidant capacity by activating the NRF2/HO-1 signaling pathway.

conclusionThis study demonstrates that SS31 preserves ovarian function by improving mitochondrial performance and redox homeostasis via the NRF2/HO-1 axis. These findings provide a solid theoretical and experimental foundation for the potential application of SS31 in delaying ovarian aging and treating related reproductive disorders, such as premature ovarian insufficiency (POI) and polycystic ovary syndrome (PCOS), highlighting its significant translational value.
