Modulating IL-11-dependent matrix stiffness to delay ovarian aging.

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
Recent studies have highlighted the crucial role of mechanical properties in the ovarian microenvironment for ovarian function. However, the mechanisms that cause ovarian matrix stiffening during aging remain incompletely understood. Here we utilized atomic force microscopy (AFM) to demonstrate that human ovarian matrix stiffness increases with aging and in pathophysiological conditions, such as chemotherapy-induced premature ovarian insufficiency (POI), polycystic ovary syndrome (PCOS) and ovarian endometriosis. By integrating proteomic analysis of human ovarian tissue with transcriptomic profiling of human ovarian fibroblasts, we identified that IL-11, which is elevated in aging ovaries of mice, rats and humans, activates fibroblasts to secrete extracellular matrix (ECM), thereby increasing ovarian matrix stiffness. Genetic deletion of Il11ra1 in mice mitigated the increase in ovarian matrix stiffness and the decline in ovarian function associated with aging, chemotherapy-induced POI and PCOS. Single-nuclei RNA sequencing (snRNA-seq) revealed that blocking Il11ra1 reduces the proportion of activated fibroblasts. Furthermore, administration of siIl11 nanoparticles to aged mice and rats enhanced fertility and reduced ovarian matrix stiffness. Together, these findings highlight the pro-inflammatory factor IL-11 in regulating ovarian matrix stiffness. We propose that anti-IL-11 therapy represents a promising translational strategy for delaying ovarian aging.
