Although heat stress is known to affect Sertoli cell fate, it remains unclear whether it triggers mitoxyperilysis and by what mechanism. Leptin is a multifunctional hormone that regulates energy metabolism and is critical for mitochondrial integrity across various cell types. However, whether leptin safeguards Sertoli cells from heat stress‑induced mitoxyperilysis remains unclear. Results In this study, the results demonstrated that heat stress induced mitochondrial oxidative damage, leading to mitochondrial DNA (mtDNA) leakage and metabolic reprogramming. Mechanistically, heat stress compromised mitochondrial membrane integrity by promoting aberrant mPTP opening, triggering BAX/BAK oligomerization, and facilitating VDAC1 oligomerization, collectively leading to mtDNA leakage into the cytosol. The cytosolic mtDNA activated the cGAS-STING signaling, subsequently triggering TBK1-IRF3 and NF-κB signaling cascades, which drove inflammatory cytokine production and ultimately culminated in mitoxyperilysis. Importantly, leptin safeguarded mitochondrial integrity, effectively prevented mtDNA release and suppressed cGAS-STING activation, thereby attenuating mitoxyperilysis. Conclusions Collectively, these findings suggest that leptin may serve as a critical guardian of mitochondrial integrity that protects Sertoli cells from heat stress-induced mitoxyperilysis, highlighting its potential to support future therapeutic strategies for heat stress-related male reproductive dysfunction.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"13 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148894563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rather than being defined only by low ruminal pH, SARA reflects a failure of acid-load adaptation, in which acid production exceeds the capacity for buffering, epithelial absorption, microbial adaptation, and host recovery. This review examines SARA within a diet–microbiota–epithelium–host framework, linking dietary acid-load pressure with microbial dysbiosis, epithelial barrier dysfunction, host inflammatory responses, diagnostic interpretation, and nutritional management. Particular emphasis is placed on interpreting ruminal pH as an indicator of acid-load exposure, integrating host-response and organ-level signals as supportive evidence for risk assessment, and matching nutritional strategies to disrupted points in acid-load control. By connecting mechanisms with diagnosis and nutritional decision-making, this review provides a structured basis for earlier SARA risk recognition and more targeted nutritional management in high-producing dairy cows.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"361 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148715735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
