High-mobility group box 1 (HMGB1) plays a crucial role in regulating autophagy in CKD. Hirudin, a potent thrombin inhibitor, has demonstrated antifibrotic and anti-inflammatory properties, but its effects on autophagy and apoptosis in CKD remain unclear. In this study, a rat model of renal interstitial fibrosis (RIF) and an HK-2 cell culture model were established to assess the effects of varying doses of hirudin and HMGB1 interference. Molecular and histological analyses, including RTqPCR, Western blot, TUNEL staining, hematoxylin-eosin (H&E) staining, immunofluorescence, and immunohistochemistry (IHC), were performed to assess renal injury, fibrosis, apoptosis, and autophagy-related markers. Hirudin treatment significantly reduced the expression of LC3, ATG12, ATG5, α-SMA, COL1A1, caspase-3, and caspase-9 while increasing P62 levels (p<0.05). It also lowered the renal coefficient (p<0.001) and apoptosis levels. The optimal effective concentration of hirudin in vitro was determined to be 4.8 ATU/mL (p<0.001). HMGB1 interference suppressed autophagy and apoptosis, as indicated by decreased LC3-II/LC3-I, ATG12, ATG5, caspase-3, and caspase-9 levels, increased P62 expression (p<0.001), and reduced apoptosis. However, simultaneous HMGB1 interference in hirudin-treated cells weakened the therapeutic effects of hirudin, leading to increased autophagy and apoptosis markers, decreased P62 levels, and a higher renal coefficient. These findings indicate that hirudin exerts protective effects in CKD by modulating autophagy and apoptosis, potentially through HMGB1 regulation. These findings highlight the therapeutic potential of targeting these mechanisms in renal dysfunction and underscore the necessity for further research to support clinical applications.</p>","PeriodicalId":50487,"journal":{"name":"European Journal of Histochemistry","volume":"69 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12038336/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This capsule encloses the central A and B regions while leaving the distal C region extracapsular. Several past studies in rat have shown that muscle spindles typically contain a single bag1 fibre, a single bag2 fibre, and two smaller chain fibres. Intrafusal fibres co-express multiple myosin heavy chain (MyHC) isoforms: -slow or -1, -slow-tonic, -α, -2a, -2b, -embryonic, and -neonatal. While MyHC-2x was previously thought absent, the recently discovered MyHC-15 isoform has been identified in the C region of rat bag fibres. Using antibodies specific for nine MyHC isoforms and analyzing four different rat skeletal muscles-soleus, extensor digitorum longus, and the lateral and medial heads of gastrocnemius-we aimed to further characterize the co-expression pattern of MyHC-15 with other known isoforms and to determine whether MyHC-2x is expressed in rat intrafusal fibres. While rodents are widely used as animal models in skeletal muscle research, notable species-specific differences in MyHC isoform expression exist. Our findings revealed that MyHC-15 expression in rat intrafusal fibres is less abundant than in human fibres. MyHC-15 was primarily observed in bag fibres but was not detected in the C region, contrary to previous reports in both rat and human. We confirmed the absence of MyHC-2x in rat intrafusal fibres. Similarly, MyHC-embryonic and -neonatal were not detected in the analyzed spindles, suggesting that previously used antibodies may have cross-reacted with MyHC-2a and -2b.
