The mutant CAG repeat triggers aberrant RNA-protein interactions and translates into toxic aggregate-prone polyglutamine protein. These aberrant RNA-protein ineractions also seed the formation of cytoplasmic liquid-like granules, such as stress granules. Emerging evidence demonstrates that granules formed via liquid-liquid phase separation can mature into gel-like inclusions that persist within the cell and may act as precursor to aggregates that occur in patients' tissue. Thus, deregulation of RNA granules is an important component of neurodegeneration. Interestingly, both the formation of intracellular membrane-less organelles like stress granules and the secretion of small extracellular vesicles (sEVs) increase upon stress and under disease conditions. sEVs are lipid membrane-bound particles that are secreted from all cell types and may participate in the spreading of misfolded proteins and aberrant RNA-protein complexes across the central nervous system in neurodegenerative diseases like HD. In this study, we performed a comparative transcriptomic analysis of sEVs and RNA granules in an HD model. RNA granules and sEVs were isolated from an inducible HD cell model. Both sEVs and RNA granules were isolated from induced (HD) and non-induced (control) cells and analyzed by RNA sequencing. Our comparative analysis between the transcriptomics data of HD RNA granules and sEVs showed that: (I) intracellular RNA granules and extracellular RNA vesicles share content, (II) several non-coding RNAs translocate to RNA granules, and (III) the composition of RNA granules and sEVs is affected in HD cells. Our data showing common transcripts in intracellular RNA granules and extracellular sEVs suggest that formation of RNA granules and sEV loading may be related. Moreover, we found a high abundance of lncRNAs in both control and HD samples, with several transcripts under REST regulation, highlighting their potential role in HD pathogenesis and selective incorporation into sEVs. The transcriptome cargo of RNA granules or sEVs may serve as a source for diagnostic strategies. For example, disease-specific RNA-signatures of sEVs can serve as biomarker of central nervous system diseases. Therefore, we compared our dataset to transcriptomic data from HD patient sEVs in blood. However, our data suggest that the cell-type specific signature of sEV-secreted RNAs as well as their high variability may make it difficult to detect these biomarkers in blood.</div></div>","PeriodicalId":49799,"journal":{"name":"Molecular and Cellular Probes","volume":"81 ","pages":"Article 102026"},"PeriodicalIF":2.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To resolve this issue, through analyzing the datasets from the online UCSC database, a novel BUB1 gene was found to be elevated in the cancerous tissues compared to their normal tissues of KIRC, and and KIRC patients with high-expressed BUB1 tended to have a worse prognosis. The subsequent experiments validated that BUB1 protein was located in both nucleus and cytoplasm of KIRC cells, and the expression levels of BUB1 gene were significantly elevated in KIRC tissues and cells, in contrast to their normal counterparts. Loss-of-function experiments verified that knockdown of BUB1 suppressed cell proliferation, mobility, epithelial-mesenchymal transition (EMT) and tumor growth, whereas induced apoptotic cell death in the KIRC cells <em>in vitro</em> and <em>in vivo</em>. In addition, bioinformatics analysis predicted that the differentially-expressed genes (DEGs) in the BUB1-deficient cohorts were enriched in the cell division-related PI3K/Akt signal pathway, and we evidenced that silencing of BUB1 was capable of inactivating the downstream PI3K/Akt signal pathway. Of note, deficiency of BUB1-induced suppressing effects on the malignant phenotypes in KIRC cells were all reversed by co-treating cells with PI3K/Akt pathway activator 740Y-P. Furthermore, it was found that the expression status of BUB1 gene were related with epigenetic modifications, immune infiltration and immunotherapy responses in KIRC. Collectively, silencing of BUB1 inhibited the progression of KIRC through inactivating the downstream PI3K/Akt signal pathway, and BUB1 gene could be potentially used as biomarkers for the diagnosis and treatment of KIRC in clinic.</div></div>","PeriodicalId":49799,"journal":{"name":"Molecular and Cellular Probes","volume":"81 ","pages":"Article 102024"},"PeriodicalIF":2.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143626545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
