Ionizing radiation-induced disruption of Rela-Bclaf1-spliceosome regulatory axis in primary spermatocytes causing spermatogenesis dysfunction.

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
introductionIonizing radiation (IR) poses a significant threat to male fertility by inducing substantial changes in the testis, yet the mechanisms underlying IR-induced spermatogenesis disorders remain poorly understood, necessitating the development of more effective radioprotective agents.
methodsWe employed Bulk RNA-seq and single-cell RNA-seq (scRNA-seq) on Balb/c mice testes models following IR exposure to assess cellular and transcriptional alterations. Histological examination, sperm concentration and motility analysis, Western blotting (WB), and reverse transcription quantitative PCR (RT-qPCR) were used to evaluate testicular injury. The therapeutic potential of NF-κB agonists was investigated in an IR-induced spermatogenesis disorder model.
resultsA 6 Gy IR dose induced spermatogenesis disorder and suppressed the spliceosome pathway, predominantly affecting the cell abundance of spermatogonia and primary spermatocytes. Bioinformatics analysis revealed that IR induced splicing disorders in differentiation-related genes, thereby impairing the differentiation ability of primary spermatocytes. Mechanistically, This IR-induced disruption was linked to IR-induced inhibition of NF-κB/Rela and Bclaf1 activity. Notably, NF-κB agonists were found to ameliorate this damage via upregulating Bclaf1 and spliceosome-related genes expression, thereby normalizing splicing patterns and rescuing IR-induced spermatogenesis disorders.
conclusionThis study reveals a novel IR-mediated Rela-Bclaf1-spliceosome regulatory axis in primary spermatocytes and propose Rela as a potential drug target for mitigating IR-induced spermatogenesis disorders. This study not only provides new insights for further research into IR-induced damage and spermatogenic disorders caused by other factors, but also offers potential therapeutic strategies for developing radioprotective agents in cancer radiotherapy.
