These diseases often afflict the elderly, leading to disability, paralysis, and other complications. Hydrogen sulfide (H2S) plays an important role in the occurrence and development of musculoskeletal diseases, which may have potential ther-apeutic significance for these diseases.RECENT ADVANCESRecently, it has been found that many musculoskeletal diseases, such as osteoporosis, periodontitis, muscle atrophy, muscle ischemia-reperfusion injury, mus-cle contraction under high fever, arthritis, and disc herniation, can be alleviated by sup-plementing H2S.

The role of H2S in more musculoskeletal disorders remains largely unknown. The importance of musculoskeletal diseases has not been widely con-cerned. Targeted delivery of H2S remains a challenging task.FUTURE DIRECTIONDevelop therapeutic drugs for musculoskeletal diseases based on H2S and test their safety, efficacy, and tolerance.

However, the contribution of 4-HNE to CSCs and cancer progression remains unclear. This study aimed to investigate the impact of 4-HNE on the regulation of CSC fate and tumor progression.METHODSHuman CRC cells were exposed to 4-HNE, and CSC signaling was analyzed using quantitative real-time PCR, immunofluorescent staining, fluorescence-activated cell sorting, and bioinformatic analysis. Tumor-promoting role of 4-HNE was confirmed using a xenograft model.RESULTSExposure of CRC cells to 4-HNE activated non-canonical Hedgehog (HH) signaling and homologous recombination repair (HRR) pathways in LGR5+ CSCs. Furthermore, blocking HH signaling led to a significant increase in the expression of γH2AX, indicating that 4-HNE induces double-stranded DNA breaks (DSBs) and simultaneously activates HH signaling to protect CSCs from 4-HNE-induced damage via the HRR pathway. Additionally, 4-HNE treatment increased the population of LGR5+ CSCs and promoted asymmetric division in these cells, leading to enhanced self-renewal and differentiation. Notably, 4-HNE also promoted xenograft tumor growth and activated CSC signaling in vivo.INNOVATION AND CONCLUSIONThese findings demonstrate that 4-HNE, as a signaling inducer in the TME, activates the non-canonical HH pathway to shield CSCs from oxidative damage, enhances the proliferation and asymmetric division of LGR5+ CSCs, and thereby facilitates tumor growth. These novel insights shed light on the regulation of CSC fate within the oxidative TME, offering potential implications for understanding and targeting CSCs for CRC therapy.","PeriodicalId":8011,"journal":{"name":"Antioxidants & redox signaling","volume":"8 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142255051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
