Clin Breast Cancer 2023:S1526-8209(23)00092-7. [PMID: 37198028 DOI: 10.1016/j.clbc.2023.04.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 04/13/2023] [Accepted: 04/20/2023] [Indexed: 05/19/2023]
Abstract
BACKGROUND Exosome-mediated transfer of long noncoding RNAs (lncRNAs) is critical for the cell-cell crosstalk in the tumor microenvironment. Nevertheless, the role of breast cancer (BC) cell-derived exosomal lncRNA in macrophage polarization during the development of BC remains unclear. METHODS The key lncRNAs carried by BC cell-derived exosomes were identified by RNA-seq. CCK-8, flow cytometry, and transwell assay were conducted to analyze the role of LINC00657 in BC cells. In addition, immunofluorescence, qRT-PCR, western blot, and MeRIP-PCR were used to evaluate the function and underlying mechanism of exosomal LINC00657 in macrophage polarization. RESULTS LINC00657 was distinctly upregulated in BC-derived exosomes and it was associated with increased m6A methylation modification levels. In addition, the depletion of LINC00657 significantly diminished the proliferative activity, migration and invasion potential of BC cells, and it also accelerated cell apoptosis. Exosomal LINC00657 from MDA-MB-231 cells could facilitate macrophage M2 activation, thus stimulating BC development in turn. Furthermore, LINC00657 activated the TGF-β signaling pathway by sequestering miR-92b-3p in macrophages. CONCLUSION Exosomal LINC00657 secreted by BC cells could induce macrophage M2 activation, and these macrophages preferentially contributed to the malignant phenotype of BC cells. These results improve our understanding of BC and suggest a new therapeutic strategy for patients with BC.

Comprehensive analysis of exosomal circRNA, lncRNA, and mRNA profiles to identify the potential RNAs involved in the pathogenesis of venous malformation. J Oral Pathol Med 2023. [PMID: 36807323 DOI: 10.1111/jop.13416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 01/11/2023] [Accepted: 01/30/2023] [Indexed: 02/22/2023]
Abstract
BACKGROUND Venous malformation (VM) is a kind of congenital vascular anomaly with a high incidence of recurrence, detailed pathogenesis and standard treatment of VM still lack now. Increasing evidence showed exosomal RNA plays a pivotal role in various diseases. However, the underlying mechanism of VM based on the potential differentially exosomal RNAs remains unclear. METHODS Comparative high-throughput sequencing with serum exosomes from three VM patients and three healthy donors was used to explore differentially expressed (DE) circRNAs, DE lncRNAs, and DE mRNAs involving the formation of VM. We identified and verified DE circRNAs, DE lncRNAs, and DE mRNAs via qRT-PCR assay. We explored the potential functions of these exosomal DE non-coding RNAs via performing further Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis. Besides, circRNA/lncRNA-miRNA-mRNA linkages were also constructed to find their potential relationships in VM. RESULTS A total of 121 circRNAs, 53 lncRNAs, and 42 mRNAs (|log2 FC| ≥ 2.0, FDR <0.05, n = 3) were determined to be differentially expressed. QRT-PCR validated that these top-changed DE circRNAs, lncRNAs, and mRNAs had significant expression changes. Functional studies demonstrated that DE circRNAs play a pivotal role in thyroid hormone signaling pathway, DE lncRNAs function as a key regulator in MAPK signaling pathway and DE miRNAs participate in the process of hepatocellular carcinoma mostly. CONCLUSION Our study comprehensively depicted exosomal DE non-coding RNAs networks related to the pathogenesis of VM which can provide new insight into, a novel target for treating VM.

Abstract
Brain arteriovenous malformations (AVMs) are characterized by a high-pressure, low-resistance vascular nidus created by direct shunting of blood from feeding arteries into arterialized veins, bypassing intervening capillaries. AVMs pose a risk of spontaneous rupture because the vessel walls are continuously exposed to increased shear stress and abnormal flow phenomena, which lead to vessel wall inflammation and distinct morphologic changes. The annual rupture rate is estimated at 2%, and once an AVM ruptures, the risk of rerupture increases 5-fold. The ability of AVMs to grow, regress, recur, and undergo remodeling shows their dynamic nature. Identifying the underlying cellular and molecular pathways of AVMs not only helps us understand their natural physiology but also allows us to directly block vital pathways, thus preventing AVM development and progression. Management of AVMs is challenging and often necessitates a multidisciplinary approach, including neurosurgical, endovascular, and radiosurgical expertise. Because many of these procedures are invasive, carry a risk of inciting hemorrhage, or are controversial, the demand for pharmacologic treatment options is increasing. In this review, we introduce novel findings of cellular and molecular AVM physiology and highlight key signaling mediators that are potential targets for AVM treatment. Furthermore, we give an overview of syndromes associated with hereditary and nonhereditary AVM formation and discuss causative genetic alterations.

Int J Med Sci 2021; 18:3768-3779. [PMID: 34790052 PMCID: PMC8579306 DOI: 10.7150/ijms.58415] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 09/20/2021] [Indexed: 01/16/2023] Open
Abstract
Background: Neuron specific enolase (NSE) is a specific biomarker for SCLC. However, the biological roles and aberrant expression of NSE in SCLC have not been well illustrated. Methods: The expression of NSE, miR-93-5p and LINC00657 in SCLC tissues and cell lines were detected using real time quantitative PCR (qRT-PCR) or immunohistochemistry. CCK8 assay was performed to detect cell proliferation. Cell migration and invasion capabilities were investigated by transwell assay. Epithelial-mesenchymal transition (EMT) process was verified by detecting epithelial marker E-cadherin and mesenchymal marker N-cadherin. The direct interactions between miR-93-5p and NSE or LINC00657 were predicted by bioinformatics tools and verified using dual luciferase reporter assay. Results: Upregulated expression of NSE in SCLC tumor tissues were positively associated with advanced tumor stage, distant metastasis and poor overall survival. Overexpression of NSE promoted cell proliferation, migration, invasion and EMT in SCLC cells, while silence of NSE inhibited these effects. Mechanically, NSE expression was positively correlated with LINC00657, and negatively correlated with miR-93-5p. Moreover, NSE was positively regulated by LINC00657 through sponging of miR-93-5p. LINC00657 and miR-93-5p promoted SCLC cell migration, invasion and EMT by NSE-mediated manner. Conclusion: Overall, our study revealed a novel role of NSE in SCLC. NSE was positively regulated by LINC00657 through competitively interacting with miR-93-5p, which may be potential targets for SCLC patients.

Abstract
BACKGROUND Striated muscle complex (SMC) dysplasia has been confirmed to contribute to postoperative defecation dysfunction of patients with anorectal malformations (ARMs). To date, the potential molecular mechanisms of SMC dysplasia underlying the development of ARMs have not been clearly explained. This study examined the expression profiles of mRNAs and lncRNAs in the malformed SMC of ARM rats using RNA sequencing (RNA-seq). METHODS A rat model of ARMs was established by the intragastric administration of 1% ethylene thiourea (ETU) on an embryonic day 10 (E10). The rats were subjected to euthanasia and the SMC samples were collected on E19. The expression of mRNAs and lncRNAs was analyzed by RNA-seq on the Illumina HiSeq2500 platform. qRT-PCR was used to confirm the results of RNA-seq. RESULTS Compared with the levels in control rats, 1408 mRNAs and 472 lncRNAs were differentially expressed in the SMC of E19 ARM rats. GO and KEGG pathway analyses showed that the top enriched GO terms were mainly related to muscle development and the enriched pathways were associated with muscle and synaptic development. Protein-protein interaction network analysis was also performed using the STRING database. The network map revealed the interaction between the WNT3 protein and NTRK1, NTF4, MUSK, and BMP5 proteins. Finally, the qRT-PCR results further confirmed the RNA-seq data. CONCLUSION Our findings indicate the involvement of these dysregulated mRNAs and lncRNAs in the pathogenesis of SMC dysplasia in ARMs, providing a theoretical foundation for developing interventions to improve postoperative defecation function.
