Exploring novel carcinogenic factors and therapeutic drugs for TNBC remains a focus to improve prognosis. Branched-chain amino acid transaminase 1 (BCAT1), a crucial enzyme in branched-chain amino acid (BCAA) metabolism, has been linked to various tumor developments, but its carcinogenic function and mechanism in TNBC remain unclear. Eupalinolide B (EB) is a naturally-derived small-molecule with anti-tumor activity, but its role in TNBC remains unknown.<h3>Objectives</h3>By exploring the targets and pharmacological mechanisms of EB in inhibiting TNBC, this study aimed to discover novel therapeutic targets and potential inhibitors for TNBC, and elucidate novel pathogenic mechanisms of TNBC.<h3>Methods</h3>The inhibitory effect of EB on TNBC was investigated using mouse models and cellular phenotypic experiments. Activity-based protein profiling (ABPP) technology, pull down-WB, CETSA-WB and MST were utilized to discover and validate the targets of EB. The oncogenic role of BCAT1 was determined through clinical data analysis and biochemical experiments. To elucidate the mechanism by which EB inhibited TNBC, many methods, including but not limited to HPLC and proteomic sequencing were used.<h3>Results</h3>We found that EB significantly inhibited TNBC progression. We identified BCAT1 as the direct target of EB and confirmed that BCAT1 was critical for TNBC development. EB inhibited BCAT1-involved BCAA metabolism to reduce the synthesis of BCAAs (including Leu, Ile, and Val), thereby inhibiting SHOC2 (a Leu-rich repeat protein) expression and the downstream SHOC2-participating RAS-ERK signaling pathway, ultimately leading to apoptosis of TNBC cells.<h3>Conclusion</h3>Collectively, this study not only elucidates the oncogenic role of BCAT1 and its downstream SHOC2-RAS-ERK signaling axis in TNBC progression but also opens up avenues for potential therapies targeting BCAT1 or BCAA metabolism (using EB alone or in combination with its inhibitor candesartan) for TNBC treatment.","PeriodicalId":14952,"journal":{"name":"Journal of Advanced Research","volume":"61 1","pages":""},"PeriodicalIF":10.7,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142519534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
