Abstract
RNA sequencing has revealed that a substantial portion of the human genome undergoes transcription, yet a minimal fraction of these transcripts translates into proteins. LncRNAs, RNA molecules less than 200 nt in length, once deemed as transcriptional noise, have now emerged as crucial regulators of numerous cellular processes. This review focuses on the lncRNA SNHG6, aiming to elucidate its biogenesis, the pivotal roles it plays, and its mechanisms in facilitating the hallmarks of cancer. A comprehensive literature review and analysis were undertaken to delve into the biogenesis of SNHG6, its roles in cellular processes, and the mechanisms through which it contributes to the hallmarks of cancer. SNHG6 is a notable lncRNA, observed to be overexpressed in various cancer types; its perturbation has been linked to tumor progression, emphasizing its significance in oncogenesis. This lncRNA contributes to a range of cellular aberrations, influencing transcriptional, post-transcriptional, and epigenetic processes of mRNA, ultimately driving cancerous transformations. LncRNA SNHG6 serves as a potential biomarker and therapeutic target due to its association with tumorigenesis. Understanding its mechanism and role in cancer can pave the way for novel diagnostic and therapeutic strategies.

[PMID: 36276078 PMCID: PMC9583869 DOI: 10.3389/fonc.2022.985962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 09/23/2022] [Indexed: 11/13/2022] Open
Abstract
Lung cancer is the malignant tumor with high invasion and metastasis, which seriously threatens public health. Previous study showed that NLRP3 could promote the occurrence of lung tumors in B(a)P-induced mice. MicroRNAs are closely related to the progression and metastasis of lung cancer by regulating target genes. However, which miRNAs affect the migration and invasion of lung cancer cells through regulating NLRP3 remains poorly defined. In this study, the miRNAs targeting NLRP3 were selected from TargetScan and miRDB database and finally miR-223-3p was chosen due to the consistent expression in both A549 and H520 cells. Then, the migration and invasion of lung cancer cells were detected with miR-223-3p mimic and inhibitor using Transwell assay, at the same time the expression of NLRP3, cleaved caspase-1, IL-1β and IL-18 was determined using Western Blot and immunohistochemistry assay. Our data demonstrated that miR-223-3p was upregulated in both A549 and H520 cells. Furthermore, the migration and invasion of A549 and H520 cells were promoted after inhibiting miR-223-3p. Besides, the levels of NLRP3, cleaved caspase-1, IL-1β and IL-18 were increased in the two lung cancer cells. And the corresponding results were contrary in miR-223-3p mimic group. Taken together, miR-223-3p attenuates the migration and invasion of NSCLC cells by regulating NLRP3, which provides evidence for the prevention and targeted treatment of NSCLC.

[PMID: 36072012 PMCID: PMC9398881 DOI: 10.1155/2022/3483498] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 07/07/2022] [Indexed: 11/17/2022] Open
Abstract
Objective To screen the cell differentiation trajectory-related genes and build a cell differentiation trajectory-related signature for predicting the prognosis of lung adenocarcinoma (LUAD). Methods LUAD single cell mRNA expression profile, TCGA-LUAD transcriptome data were obtained from GEO and TCGA databases. Single-cell RNA-seq data were used for cell clustering and pseudotime analysis after dimensionality reduction analysis, and the cell differentiation trajectory-related genes were acquired after differential expression analysis conducted between the main branches. Then, the consensus clustering analysis was carried out on TCGA-LUAD samples, and the GSEA analysis was performed, then the differences on the expression levels of immune checkpoint genes and immunotherapy response were compared among clusters. The prognostic model was constructed, and the GSE42127 dataset was used to validate. A nomogram evaluation model was used to predict prognosis. Results Two subsets with distinct differentiation states were found after cell differentiation trajectory analysis. TCGA-LUAD samples were divided into two cell differentiation trajectory-related gene-based clusters, GSEA found that cluster 1 was significantly related to 20 pathways, cluster 2 was significantly enriched in three pathways, and it was also shown that clusters could better predict immune checkpoint gene expression and immunotherapy response. A six cell differentiation-related genes-based prognostic signature was constructed, and the patients in the high-risk group had poorer prognosis than those in the low-risk group. Moreover, a nomogram was constructed based on the prognostic signature and clinicopathological features, and this nomogram had strong predictive performance and high accuracy. Conclusion The cell differentiation-related signature and the prognostic nomogram could accurately predict survival.

J Gastrointest Oncol 2021; 12:1811-1822. [PMID: 34532130 PMCID: PMC8421904 DOI: 10.21037/jgo-21-319] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 07/22/2021] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND microRNAs (miRNAs) have been shown to significantly contribute to the pathogenesis of various tumors, including hepatocellular carcinoma (HCC). Specifically, miR-744-5p has been shown to be associated with tumor development, but the underlying mechanism by which miR-744-5p affects HCC remains unclear. Thus, this study sought to explore the molecular mechanism governing the function of miR-744-5p in HCC. METHODS The expression of miR-744-5p in HCC tissues/cells was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Colony-formation, cell-counting kit 8 (CCK-8), Transwell, and wound-healing assays were used to assess the proliferation and metastasis of HCC cells. Additionally, the interaction between miR-744-5p and transforming growth factor-beta 1 (TGF-β1) was detected using a dual-luciferase reporter and a Western-blot analysis. RESULTS miR-744-5p expression was shown to be significantly reduced in HCC tissues and cells. The overexpression of miR-744-5p not only significantly inhibited HCC cell proliferation, but also significantly reduced epithelial-mesenchymal transition-induced invasion. A luciferase reporter assay validated the ability of miR-744-5p to directly target TGF-β1. Further, the overexpression of TGF-β1 appeared to abolish the inhibitive effect of miR-744-5p mimics on HCC development. CONCLUSIONS As per our findings, it was revealed that miR-744-5p suppresses HCC proliferation and invasion by regulating the TGF-β1 signaling pathway and epithelial-mesenchymal-transition (EMT).

Abstract
Background Non-small cell lung cancer (NSCLC) is a leading threat to human lives with high incidence and mortality. Circular RNAs were reported to play important roles in human cancers. The purpose of this study was to investigate the role of circ_0005962 and explore the underlying functional mechanisms. Methods The protein levels of Beclin 1, light chain3 (LC3-II/LC3-I), Pyruvate dehydrogenase kinase 4 (PDK4), Cleaved Caspase 3 (C-caspase 3), and proliferating cell nuclear antigen were examined using western blot analysis. Glycolysis was determined according to the levels of glucose consumption and lactate production. Xenograft model was constructed to investigate the role of circ_0005962 in vivo. Result circ_0005962 expressed with a high level in NSCLC tissues and cells. circ_0005962 knockdown inhibited proliferation, autophagy, and glycolysis but promoted apoptosis in NSCLC cells. miR-382-5p was targeted by circ_0005962, and its inhibition reversed the role of circ_0005962 knockdown. Besides, PDK4, a target of miR-382-5p, was regulated by circ_0005962 through miR-382-5p, and its overexpression abolished the effects of miR-382-5p reintroduction. circ_0005962 knockdown suppressed tumor growth in vivo. Conclusion circ_0005962 knockdown restrained cell proliferation, autophagy, and glycolysis but stimulated apoptosis through modulating the circ_0005962/miR-382-5p/PDK4 axis. Our study broadened the insights into understanding the mechanism of NSCLC progression.

Abstract
Circulating microRNAs (miRNAs) have been demonstrated as robust and promising biomarkers for non-small cell lung cancer (NSCLC). Our aim was to determine the significance of serum exosomal miR-382 in NSCLC. Circulating exosomes were collected from 126 patients with NSCLC and 60 normal controls before treatment and one month after surgery. The circulating exosomal miR-382 expression was measured with quantitative RT-PCR (qRT-PCR) in all the participants. Our findings demonstrated that circulating exosomal miR-382 was very reduced in NSCLC. In addition, it showed high accuracy for discriminating NSCLC patients from healthy subjects. Interestingly, serum exosomal miR-382 improved the diagnostic accuracy of carcinoembryonic antigen (CEA). Moreover, its level increased significantly one month following surgical resection. Reduced circulating exosomal miR-382 was positively associated with poor clinical variables. NSCLC cases with lower serum exosomal miR-382 suffered worse overall survival (OS) and serum exosomal miR-382 was independently associated with OS. Taken together, circulating exosomal miR-382 is a robust biomarker for evaluating the progression of NSCLC.

Abstract
Non-small cell lung cancer is one of the leading causes of cancer-related death worldwide. MicroRNAs have been characterized as critical regulators for cancer progression including non-small cell lung cancer. This work explored microRNA-744-5p expression in non-small cell lung cancer cell lines and normal cell line using quantitative real-time polymerase chain reaction. Connection of microRNA-744-5p and paired box 2 was analyzed with bioinformatic analysis, luciferase activity reporter assay, and Western blot. Effects of microRNA-744-5p or paired box 2 expression on non-small cell lung cancer cell behaviors were analyzed using a series of in vitro experiments. MicroRNA-744-5p was found to have decreased expression in non-small cell lung cancer cell lines compared with normal cell line. Paired box 2 was identified as a direct target for microRNA-744-5p in non-small cell lung cancer. Overexpression of microRNA-744-5p inhibits non-small cell lung cancer cell proliferation, colony formation, and cell invasion in vitro through targeting paired box 2. The present study provided novel insights into the biological functions of microRNA-744-5p in non-small cell lung cancer.

Abstract
Lung cancers and malignant pleural mesothelioma (MPM) have some of the worst 5-year survival rates of all cancer types, primarily due to a lack of effective treatment options for most patients. Targeted therapies have shown some promise in thoracic cancers, although efficacy is limited only to patients harboring specific mutations or target expression. Although a number of actionable mutations have now been identified, a large population of thoracic cancer patients have no therapeutic options outside of first-line chemotherapy. It is therefore crucial to identify alternative targets that might lead to the development of new ways of treating patients diagnosed with these diseases. The multifunctional oncoprotein Y-box binding protein-1 (YB-1) could serve as one such target. Recent studies also link this protein to many inherent behaviors of thoracic cancer cells such as proliferation, invasion, metastasis and involvement in cancer stem-like cells. Here, we review the regulation of YB-1 at the transcriptional, translational, post-translational and sub-cellular levels in thoracic cancer and discuss its potential use as a biomarker and therapeutic target.
