BETd-246 serves as a tethering agent that links BETi-211 to thalidomide for the development of BET degraders. This compound has demonstrated superior efficacy in tumor treatment compared with traditional BET inhibitors. However, the anti-tumor effects and molecular mechanisms underlying the action of BETd-246 in T-ALL remain poorly understood. The aim of our study was to investigate the anti-tumor effects of BETd-246 and provide new insights into treatment strategies for T-ALL. In human T-ALL cell lines, BETd-246 induced degradation of BET proteins, particularly BRD4, at nanomolar concentrations. It effectively inhibited cell growth, disrupted the cell cycle, and promoted apoptosis in T-ALL cells in a concentration-dependent manner. The effects of BETd-246 were more pronounced than those of JQ1. <em>In vivo</em> experiments revealed that treatment with BETd-246 reduced proliferation and invasion of T-ALL cells and extended survival time in mouse models. RNA sequencing analysis indicated significant downregulation of T-cell receptor (TCR)-associated transmembrane adaptor 1 (TRAT1) expression in T-ALL cells treated with BETd-246. Knocking down TRAT1 resulted in increased growth inhibition and enhanced apoptosis within these cells. These findings suggest that TRAT1 plays a crucial role in mediating the effects of BETd-246 in T-ALL. Overall, our results indicate that BETd-246 is a promising therapeutic agent for treating this aggressive form of leukemia.</div></div>","PeriodicalId":12227,"journal":{"name":"Experimental cell research","volume":"453 2","pages":"Article 114791"},"PeriodicalIF":3.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145274358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a cell-based assay using primary human trophoblasts has been developed to identify compounds that inhibit sFLT1 secretion, routine application of this assay is limited owing to the complexity of isolating these cells from the placenta and their inability to be passaged.

Their high proliferative ability allows for obtaining sufficient STBs for drug screening. In the present study, we investigated whether hTSC-differentiated STBs (dSTBs) exhibit enhanced secretion of sFLT1 under hypoxic conditions, similar to primary trophoblasts.

CREPT knockdown reduced NPC cell viability, proliferation and enhanced NPC cell apoptosis and suppressed tumor growth through deactivating Wnt/β-catenin pathway, but the results of ALYREF overexpression had the inverse results of CREPT knockdown. Furthermore, the combination of CREPT knockdown and ALYREF overexpression compromised ALYREF overexpression-mediated the influences on NPC cells, tumor growth and motivating Wnt/β-catenin pathway. Furthermore, ALYREF interacted with CREPT mRNA and ALYREF promoted the stability of CREPT mRNA in m5C-dependent manner.</div></div><div><h3>Conclusion</h3><div>ALYREF stabilized CREPT mRNA through interacting with m5C-labeled CREPT mRNA to elevate CREPT expression, thus activating Wnt/β-catenin pathway and facilitating NPC progression.</div></div>","PeriodicalId":12227,"journal":{"name":"Experimental cell research","volume":"452 2","pages":"Article 114747"},"PeriodicalIF":3.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145029123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
