The underlying causes of NOA remain largely unidentified, leading to a dearth of effective clinical interventions. This study aimed to explore a potential biomarker for NOA, and to elucidate the underlying mechanisms involved. The RNA-sequencing of the testis tissue revealed that miR-34a-5p increased, while CDC25A mRNA decreased in NOA patients compared to obstructive azoospermia (OA) controls. RT-qPCR confirmed that miR-34a-5p was upregulated in the seminal plasma of NOA patients compared to healthy individuals, demonstrating its potential as a discriminatory marker for distinguishing between NOA and healthy individuals. The dual-luciferase assay demonstrated that miR-34a-5p directly targets CDC25A and inhibits the cell proliferation of TM4, GC-1 and GC-2 cells by arresting the cell cycle at the G1 phase. Both in vitro and in vivo experiments, the overexpression of miR-34a-5p led to a reduction in the level of CDC25A and CCNB1, accompanied by an elevation in the level of CDK1 phosphorylation. In mice overexpressing miR-34a-5p, the testicular size, testicular organ coefficient, total epididymal sperm count and motility were significantly decreased, the structure of seminiferous tubules was disrupted, and the abnormal tubules was significantly increased. In summary, miR-34a-5p causes cell cycle arrest by targeting CDC25A, inhibiting the expression of CDC25A and CCNB1, preventing the dephosphorylation of CDK1, which ultimately leads to male spermatogenic failure.

These inflammasomes play a crucial role in CAPS patients' inflammatory episodes, these being primarily driven by the production of interleukin (IL)-1b. Although treatment with IL-1 blockers is effective for CAPS, some patients develop refractory responses and adverse reactions to these therapies. Consequently, there is a need for novel treatments for CAPS patients. Promising candidates are the derivatives of itaconate, which have been shown to impair NLRP3 inflammasome activation and IL-1β release in blood mononuclear cells from CAPS patients. In this study, we provide insight into the inhibitory mechanisms by which the itaconate derivative 4-octyl itaconate (4-OI) acts on NLRP3 that has different gain-of-function mutations (p.R262W, p.D305N and p.T350M) associated with CAPS. Notably, 4-OI effectively blocks the basal auto-activation of the inflammasome formed by NLRP3 p.R262W, p.D305N and p.T350M variants, which in turn reduces caspase-1 activation, gasdermin D processing, and IL-18 release. Furthermore, after lipopolysaccharide priming of macrophages, 4-OI also decreases IL-1β gene expression and release. Overall, 4-OI impairs CAPS-associated inflammasome function at multiple levels, meaning that therapeutic agents based on itaconate could be a promising therapeutic approach to managing inflammatory episodes in CAPS patients carrying p.R262W, p.D305N or p.T350M variants.</p>","PeriodicalId":10007,"journal":{"name":"Cellular and Molecular Life Sciences","volume":"82 1","pages":"209"},"PeriodicalIF":6.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12102053/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144132132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advances in genetic engineering, neuroimaging and molecular biology have deepened our understanding of astrocytic functions. This review highlights the different mechanisms by which astrocytes regulate sleep, notably through transcriptomic and morphological changes, as well as gliotransmission, whereby intracellular calcium (Ca<sup>2+</sup>) dynamics plays a significant role in modulating the sleep-wake cycle. In vivo optogenetic stimulation of astrocytes indeed induces ATP release, which is subsequently degraded into adenosine, modulating neuronal excitability in sleep-wake regulatory brain regions. Astrocytes also participate in synaptic plasticity, potentially modulating sleep-associated downscaling, a process essential for memory consolidation and preventing synaptic saturation. Although astrocytic involvement in synaptic maintenance is well supported, the precise molecular mechanisms linking these processes to sleep regulation remain to be elucidated.

In this work, we found CASP1 transcription and the level of pyroptosis were significantly elevated in the villous tissues of URSA patients. Suppression of cell pyroptosis by Gasdermin-D (GSDMD) or Caspase-1 inhibitors can reduce embryo resorption rate of URSA mice, while Caspase-1 over-expression in normal pregnant (NP) mice can aggravate embryo resorption. Meanwhile, a pronounced decline in the expression of microRNA-126-5p (miR-126-5p) was found in URSA patients, which was inversely related to CASP1 expression. Over-expression of miR-126-5p restrained trophoblast pyroptosis via inhibiting Caspase-1/GSDMD signaling pathway by direct binding to 3'-UTR of CASP1. Moreover, experiments in vivo substantiated that up-regulation of miR-126-5p effectively suppressed Caspase-1-mediated pyroptosis in placental tissue and significantly reduced embryo resorption rate. Collectively, these results underscored that diminished miR-126-5p expression plays a crucial role in URSA by enhancing trophoblast pyroptosis through activating Caspase-1/GSDMD signaling pathway. As a result, miR-126-5p shows significant promise as a possible biomarker for diagnosis and treatment of URSA.</p>","PeriodicalId":10007,"journal":{"name":"Cellular and Molecular Life Sciences","volume":"82 1","pages":"204"},"PeriodicalIF":6.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12081782/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144076314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
