Mfn2 regulates mitochondria-associated ER membranes to affect PCOS oocyte development.
Article in Endocrine connections, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
This study aimed to investigate the role of mitochondrial-related protein Mfn2 in polycystic ovary syndrome (PCOS) and its impact on oocyte development. The pathological features of PCOS model mice were confirmed by hematoxylin-eosin staining and immunohistochemistry. The expression of Mfn2 and mitochondrial-related proteins in PCOS oocytes and granulosa cells was detected by qRT-PCR and Western blot. Mitochondrial quantity was measured by Mito-Tracker staining, and the structure of mitochondria-associated ER membranes (MAMs) was observed by transmission electron microscopy. The results showed that Mfn2 was significantly downregulated in PCOS oocytes and granulosa cells, and its expression was inhibited in oocytes at different developmental stages. Moreover, the structure of MAMs was also disrupted. Downregulation of Mfn2 expression led to a reduction in mitochondrial quantity in oocytes and granulosa cells, as well as disruption of MAM structure, while overexpression of Mfn2 had the opposite effect. In conclusion, this study indicates that Mfn2 affects the development of PCOS oocytes by regulating MAMs and may be involved in maintaining the stability of MAM structure and function, thereby affecting mitochondrial quantity and function. These findings provide new insights into the pathogenesis and treatment of PCOS.
