Exploration and identification of novel inhibitors targeting ABCB1 and ABCG2 are necessary to overcome the related MDR. Mobocertinib is an approved EGFR/HER2 inhibitor for non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion mutations. This study demonstrates that mobocertinib can potentially reverse ABCB1- and ABCG2-mediated MDR. Our findings indicate a strong interaction between mobocertinib and these two proteins, supported by its high binding affinity with ABCB1 and ABCG2 models. Through inhibiting the drug efflux function of ABCB1 and ABCG2, mobocertinib facilitates substrate drugs accumulation, thereby re-sensitizing substrate drugs in drug-resistant cancer cells. Additionally, mobocertinib inhibited the ATPase activity of ABCB1 and ABCG2 without changing the expression levels or subcellular localization. In the tumor-bearing mouse model, mobocertinib boosted the antitumor effect of paclitaxel and topotecan, resulting in tumor regression. In summary, our study uncovers a novel potential for repurposing mobocertinib as a dual inhibitor of ABCB1 and ABCG2, and suggests the combination of mobocertinib with substrate drugs as a strategy to counteract MDR.</div></div>","PeriodicalId":9506,"journal":{"name":"Cancer letters","volume":"607 ","pages":"Article 217309"},"PeriodicalIF":9.1,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142557250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, romidepsin has noted toxicities in humans and so here we aimed to define the primary mechanisms through which HDAC1/2 mediate OS progression to identify more selective druggable targets/pathways. Microarray and proteomics analyses of romidepsin treated OS cells revealed a significant suppression of neuropilin-1 (NRP1), a known regulator of cancer cell migration and invasion.

More strikingly, <em>in vivo</em>, reduced NRP1 expression significantly mitigated the lung metastatic potential of OS in two independent models (K7M2 and SAOS-LM7). Mechanistically, our data point to NRP1 mediating this effect via the down regulation of migration machinery, namely SRC, FAK and ROCK1 expression/activity, that is in part, related to NRP1 interaction with integrin beta 1 (ITGB1). In summary, our data indicate that romidepsin down regulation of NRP1 significantly mitigates the ability of OS cells to seed the lung and establish metastases, and that targeting NRP1 or its effectors with selective inhibitors may be a viable means with which to prevent this deadly aspect of the disease.</div></div>","PeriodicalId":9506,"journal":{"name":"Cancer letters","volume":"606 ","pages":"Article 217302"},"PeriodicalIF":9.1,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142458716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study utilized bioinformatic analysis of publicly available CRPC single-cell data to develop a consensus glucocorticoid-related signature (Glu-sig) that can serve as an independent predictor for relapse-free survival.

Mechanistically, targeting GPD1 induced the production of sphingosine 1-phosphate (S1P) and enhanced histone acetylation, thereby inducing the transcription of p21 that involved in cell cycle regulation.
