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

objectiveThis study investigates the therapeutic potential of interleukin-22 (IL-22) in polycystic ovary syndrome (PCOS) and its mechanisms.

methodsA dehydroepiandrosterone (DHEA)-induced PCOS mouse model and testosterone-treated human KGN granulosa cells were utilized. Mice received IL-22 (50-100 µg/kg) or Diane-35 for 3 weeks.

resultsIL-22 administration restored estrous cyclicity, reduced ovarian cysts, and normalized serum testosterone and insulin levels in DHEA or letrozole-induced PCOS mice. DHEA induction led to mitochondrial damage in granulosa cells (GCs), evidenced by impaired mitochondrial membrane potential, mtDNA copy number depletion, and ROS accumulation, alongside lipid metabolic dysregulation. These detrimental effects were ameliorated by IL-22. Bioinformatics analysis of PCOS patient data revealed significant enrichment in lipid metabolism pathways. A high-fat diet abolished IL-22's PCOS-restoring effects, underscoring lipid metabolism as a key mechanism. We identified 19 lipid metabolism-related genes, with ETS1 being the most significantly regulated. IL-22 inhibited ETS1 expression induced by DHEA through the activation of STAT3 dependent on the IL-22R1, and Chromatin Immunoprecipitation (ChIP)-PCR confirmed STAT3 binding to the ETS1 promoter.

conclusionOur findings highlight IL-22 as a promising therapeutic candidate for PCOS, acting through the IL-22R1/STAT3/ETS1 pathway to ameliorate mitochondrial dysfunction and lipid metabolic reprogramming in GCs. This study bridges immune signaling with metabolic pathology in PCOS, offering novel avenues for targeted intervention.
