Transcriptomic analysis of mouse testes with disordered spermatogenesis induced by high-dose BPA exposure during puberty.
Article in Molecular biology reports, 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
backgroundBisphenol A (BPA) can simulate estrogen, disrupt the endocrine system, affect the development of the nervous and immune systems, and cause fertility problems, precocious puberty, and even lead to various hormone-related cancers. However, little is known about the mRNA expression profile in testes exposed to BPA. METHODS AND
resultsThis study focuses on the transcriptome of mouse testes with impaired spermatogenesis induced by BPA exposure during puberty. Twenty-one-day-old mice were treated with 30 and 300 mg/kg/d BPA by intragastric administration for a specific number of days prior to transcriptomic analysis. No significant damage to spermatogenesis was observed after intragastric administration with 30 and 300 mg/kg/d BPA for 10 and 30 days. However, significant sperm damage was observed after 50 days of treatment with both doses, showing a concentration-dependent effect. Transcriptomic analysis of testes from mice treated for 50 days revealed 126 significantly upregulated and 32 significantly downregulated genes in 30 mg/kg/d BPA-treated testes, and 775 significantly upregulated and 695 significantly downregulated genes in 300 mg/kg/d BPA-treated testes. The extracellular matrix (ECM)-receptor interaction signaling pathway was involved in regulating the spermatogenesis of BPA-treated testes. RT-qPCR confirmed that BPA (30 and 300 mg/kg/d) significantly increased testicular mRNA levels of Plekha4, Cd24a, and Fos, and decreased those of Srd5a1, Nrg3, and Abca4.
conclusionsTranscriptomic analysis of mouse testes with impaired spermatogenesis induced by high-dose BPA exposure during puberty, revealing significantly upregulated and downregulated genes.
