The crosslink between autophagy and ferroptosis in polycystic ovary syndrome: from synergistic pathogenesis to targeted therapy.
Review in Journal of ovarian research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Polycystic ovary syndrome (PCOS) is a highly heterogeneous endocrine-metabolic disorder whose core pathological features-follicular atresia and ovulatory dysfunction-are attributed to functional failure of ovarian granulosa cells (GCs). Although autophagy (a cellular quality-control mechanism) and ferroptosis (iron-dependent lipid peroxidation-driven cell death) have been shown to independently contribute to the pathophysiology of PCOS, their interactive networks and regulatory mechanisms within specific pathological microenvironments remain to be systematically elucidated. This review aims to systematically unravel this overlooked micro-pathogenic network. The dysfunction of GCs in PCOS is not an isolated event involving a single mode of cell death, but rather a pathological crosstalk arising from the disruption of the dynamic equilibrium between autophagy and ferroptosis. This paper elucidates the pathological mechanisms driving this cascade of disturbances through four distinct pathways: the intracellular stress hub formed by the synergistic action of oxidative stress (OS) and endoplasmic reticulum stress (ERS) serves as the initiating factor. This is compounded by the gut-ovarian axis's long-range amplification effect, mediated by gut microbiome (GM) dysregulation and low-grade chronic inflammation (LGI), collectively disrupting cellular homeostasis. while circadian rhythm disruption and epigenetic reprogramming, respectively, cement this imbalance at the temporal and molecular memory levels. Moreover, we have elucidated the specific execution pathways of autophagy-dependent ferroptosis, namely how selective autophagy (e.g., ferritinophagy and mitophagy) acts as a key amplifier of ferroptosis by exacerbating iron overload and energy collapse. On this basis, this paper explores therapeutic strategies ranging from upstream restoration of signal homeostasis to downstream precise inhibition of autophagy-ferroptosis interaction nodes. This review aims to provide novel theoretical perspectives for fundamentally reversing follicular atresia in PCOS and improving patients' reproductive outcomes by re-examining these lethal interactions at the microscopic level.
