This article critically examines and discusses recent research on the roles of G protein-coupled receptors (GPCRs) in myeloma, lymphomas, and leukemias with a particular focus on pediatric acute lymphoblastic (lymphocytic) leukemia (ALL). By utilizing RNA sequencing (RNA-seq), we analyzed GPCR expression patterns in pediatric ALL samples (aged 3-12 years old), with a further focus on Class A orphan GPCRs. Our analysis revealed distinct GPCR expression profiles in pediatric ALL, identifying several candidates with aberrant upregulated expression compared with healthy counterparts. Among these GPCRs, GPR85, GPR65, and GPR183 have varying numbers of studies in the field of hematological cancers and pediatric ALL. Furthermore, we explored missense mutations of pediatric ALL in relation to the RNA gene expression findings, providing insights into the genetic underpinnings of this disease. By integrating both RNA-seq and missense mutation data, this article aims to provide an insightful and broader perspective on the potential correlations between specific GPCR and their roles in pediatric ALL.</p>","PeriodicalId":36426,"journal":{"name":"ACS Pharmacology and Translational Science","volume":"7 12","pages":"4000-4009"},"PeriodicalIF":4.9,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11651347/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142855619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main strategy of endocrine therapy for ERα+ breast cancer is to inhibit the ERα signaling pathway and downregulate ERα levels, which often results in mutations in the ligand-binding domain (LBD) of ERα, leading to significant resistance to subsequent treatment in patients. To combat drug resistance, we first proposed a novel aptamer PROTAC strategy through specifically targeted degradation of ERα via targeting the DNA-binding domain (DBD) of ERα. We proved that this strategy is capable of targeting ERα for degradation through ubiquitination, leading to the inhibition of proliferation in ERα+ breast cancer cells and tamoxifen-resistant breast cancer cells. Furthermore, we investigated the mechanisms involved in overcoming resistance. By circumventing drug resistance associated with LBD mutations in ERα, our approach provides a promising avenue for the discovery of new therapeutic agents.</p>","PeriodicalId":36426,"journal":{"name":"ACS Pharmacology and Translational Science","volume":"7 12","pages":"3945-3954"},"PeriodicalIF":4.9,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11650730/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142855790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
