J Med Biochem 2024; 43:503-511. [PMID: 39139172 PMCID: PMC11318845 DOI: 10.5937/jomb0-47889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 01/23/2024] [Indexed: 08/15/2024] Open
Abstract
Background To systematically evaluate the relationship between the expression level of long noncoding RNA NEAT1 and the clinical characteristics and prognostic value of rectal cancer patients. Methods PubMed, EMBASE, Cochrane library database and case-control studies on the correlation between abnormal expression of lncRNA NEAT1 and prognosis of rectal cancer patients published by the American clinical trials registry before May 1, 2023 were searched. The search time was from the establishment of the database to May 30, 2023. Results A total of 7 case-control studies were included, including 1063 cancer patients. The results of meta-analysis showed that the high expression of lncRNA NEAT1 was significantly correlated with the degree of differentiation [or=0.45, 95%CI=0.32-0.63, P<0.01], tumor size [or=0.59, 95%CI=0.42-0.82, P<0.01], and overall survival [HR=1.34, 95%CI=1.21-1.48, P<0.001]; However, it was not associated with gender [or=1.23, 95%CI= 0.88-1.72, P=0.23] and lymph node metastasis [or=0.87, 95%CI=0.45-1.66, P=0.67]. Conclusions The high expression of lncRNA NEAT1 may be a risk factor for poor prognosis in patients with malignant tumors, and lncRNA NEAT1 can be used as a potential biomarker to evaluate its prognosis.

Abstract
Long non-coding RNAs (lncRNAs) present pivotal roles in cancer tumorigenesis and progression. Recently, nuclear paraspeckle assembly transcript 1 (NEAT1) as a lncRNA has been shown to mediate cell proliferation, migration, and EMT in tumor cells. NEAT1 by targeting several miRNAs/mRNA axes could regulate cancer cell behavior. Therefore, NEAT1 may function as a potent biomarker for the prediction and treatment of some human cancers. In this review, we summarized various NEAT1-related signaling pathways that are critical in cancer initiation and progression.

Abstract
Acute lung injury (ALI) and its severe form, acute respiratory distress syndrome (ARDS), represent an acute stage of lung inflammation where the alveolar epithelium loses its functionality. ALI has a devastating impact on the population as it not only has a high rate of incidence, but also has high rates of morbidity and mortality. Due to the involvement of multiple factors, the pathogenesis of ALI is complex and is not fully understood yet. Long noncoding RNAs (lncRNAs) are a group of non-protein-coding transcripts longer than 200 nucleotides. Growing evidence has shown that lncRNAs have a decisive role in the pathogenesis of ALI. LncRNAs can either promote or hinder the development of ALI in various cell types in the lungs. Mechanistically, current studies have found that lncRNAs play crucial roles in the pathogenesis of ALI via the regulation of small RNAs (e.g., microRNAs) or downstream proteins. Undoubtedly, lncRNAs not only have the potential to reveal the underlying mechanisms of ALI pathogenesis but also serve as diagnostic and therapeutic targets for the therapy of ALI.

Abstract
Colorectal cancer (CRC) is the third cause of cancer death in the world that arises from the glandular and epithelial cells of the large intestine, during a series of genetic or epigenetic alternations. Recently, long non-coding RNAs (lncRNAs) has opened a separate window of research in molecular and translational medicine. Emerging evidence has supported that lncRNAs can regulate cell cycle of CRC cells. LncRNA NEAT1 has been verified to participate in colon cancer development and progression. NEAT1 as a competing endogenous RNA could suppress the expression of miRNAs, and then regulate molecules downstream of these miRNAs. In this review, we summarized emerging roles of NEAT1 in CRC cells.

Abstract
Alzheimer's disease (AD), a heterogeneous neurodegenerative disorder, is the most common cause of dementia accounting for an estimated 60–80% of cases. The pathogenesis of AD remains unclear, and no curative treatment is available so far. Increasing evidence has revealed a vital role of non-coding RNAs (ncRNAs), especially long non-coding RNAs (lncRNAs), in AD. LncRNAs contribute to the pathogenesis of AD via modulating amyloid production, Tau hyperphosphorylation, mitochondrial dysfunction, oxidative stress, synaptic impairment and neuroinflammation. This review describes the biological functions and mechanisms of lncRNAs in AD, indicating that lncRNAs may provide potential therapeutic targets for the diagnosis and treatment of AD.

Abstract
INTRODUCTION Laryngeal squamous cell carcinoma (LSCC) is diverse in its natural history and responsiveness to treatments. There is an urgent need to generate candidate biomarkers for the stratification and individualization of treatment to avoid overtreatment or inadequate treatment. Long noncoding RNA nuclear paraspeckle assembly transcript 1 (NEAT1) has been identified as an oncogenic gene in multiple human tumors entitles, and dysregulation of NEAT1 was tightly linked to carcinogenesis and cancer progression. METHODS One hundred two paraffin samples of LSCC patients were collected. Furthermore, in situ hybridization (ISH), Kaplan-Meier, and MTT were used to analyze the relationship between NEAT1 and the progress of LSCC. RESULTS In this study, ISH revealed that NEAT1 was strongly expressed in the nucleus. The increased expression of NEAT1 was correlated with T grade, neck nodal metastasis, clinical stage, drinking history, or smoking history of LSCC. The Kaplan-Meier analysis indicated that patients with higher NEAT1 expression had a worse overall survival in LSCC patients. In addition, NEAT1 knockdown significantly inhibited the growth of LSCC cells. CONCLUSION Together, these results suggested that NEAT1 involved in the progress of LSCC and might act as a tumor oncogenic gene. This study provides a potential new marker and target for gene therapy in the treatment of LSCC.

Abstract
Celiac disease (CD) is an autoimmune enteropathy arising in genetically predisposed subjects exposed to gluten, which activates both innate and adaptive immunity. Although the pathogenesis is common to all patients, the clinical spectrum is quite variable, and differences could be explained by gene expression variations. Among the factors able to affect gene expression, there are lncRNAs. We evaluated the expression profile of 87 lncRNAs in CD vs. healthy control (HC) intestinal biopsies by RT-qPCR array. Nuclear enriched abundant transcript 1 (NEAT1) and taurine upregulated gene 1 (TUG1) were detected as downregulated in CD patients at diagnosis, but their expression increased in biopsies of patients on a gluten-free diet (GFD) exposed to gluten. The increase in NEAT1 expression after gluten exposure was mediated by IL-15 and STAT3 activation and binding to the NEAT1 promoter, as demonstrated by gel shift assay. NEAT1 is localized in the nucleus and can regulate gene expression by sequestering transcription factors, and it has been implicated in immune regulation and control of cell proliferation. The demonstration of its regulation by gluten thus also supports the role of lncRNAs in CD and prompts further research on these RNAs as gene expression regulators.

Abstract
Nuclear paraspeckles assembly transcript 1 (NEAT1) is a well-known long noncoding RNA (lncRNA) with various functions in different physiological and pathological processes. Notably, aberrant NEAT1 expression is implicated in the pathogenesis of various neurodegenerative diseases, including Alzheimer's disease (AD). However, the molecular mechanism of NEAT1 in AD remains poorly understood. In this study, we investigated that NEAT1 regulated microtubules (MTs) polymerization via FZD3/GSK3β/p-tau pathway. Downregulation of NEAT1 inhibited Frizzled Class Receptor 3 (FZD3) transcription activity by suppressing H3K27 acetylation (H3K27Ac) at the FZD3 promoter. Our data also demonstrated that P300, an important histone acetyltransferases (HAT), recruited by NEAT1 to bind to FZD3 promoter and mediated its transcription via regulating histone acetylation. In addition, according to immunofluorescence staining of MTs, metformin, a medicine for the treatment of diabetes mellitus, rescued the reduced length of neurites detected in NEAT1 silencing cells. We suspected that metformin may play a neuroprotective role in early AD by increasing NEAT1 expression and through FZD3/GSK3β/p-tau pathway. Collectively, NEAT1 regulates microtubule stabilization via FZD3/GSK3β/P-tau pathway and influences FZD3 transcription activity in the epigenetic way.

Abstract
With advances in genome and transcriptome research technology, the function and mechanism of lncRNAs in physiological and pathological states have been gradually revealed. Nuclear Enriched Abundant Transcript 1 (NEAT1, a long non-coding RNA), a vital component of paraspeckles, plays an indispensable role in the formation and integrity of paraspeckles. Throughout the research history, NEAT1 is mostly aberrantly upregulated in various cancers, and high expression of NEAT1 often contributes to poor prognosis of patients. Notably, the role and mechanism of NEAT1 in liver diseases have been increasingly reported. NEAT1 accelerates the progression of non-alcoholic fatty liver disease (NAFLD), liver fibrosis and hepatocellular carcinoma, while exerting a protective role in the pathogenesis of acute-on-chronic liver failure by inhibiting the inflammatory response. In this review, we will elaborate on relevant studies on the different casting of NEAT1 in liver diseases, especially focusing on its regulatory mechanisms and new opportunities for alcoholic liver disease.

Abstract
Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) are noncoding RNAs (ncRNAs) that occupy over 90% of the human genome, and their main function is to directly or indirectly regulate messenger RNA (mRNA) expression and participate in the tumorigenesis and progression of malignances. In particular, some lncRNAs can interact with miRNAs as competing endogenous RNAs (ceRNAs) to modulate mRNA expression. Accordingly, these RNA molecules are interrelated and coordinate to form a dynamic lncRNA-mediated ceRNA regulatory network. Mounting evidence has revealed that lncRNAs that act as ceRNAs are closely related to tumorigenesis. To date, numerous studies have established many different regulatory networks in hepatocellular carcinoma (HCC), and perturbations in these ceRNA interactions may result in the initiation and progression of HCC. Herein, we emphasize recent advances concerning the biological function of lncRNAs as ceRNAs in HCC, with the aim of elucidating the molecular mechanism underlying these HCC-related RNA molecules and providing novel insights into the diagnosis and treatment of HCC.

Abstract
Apoptosis of vascular smooth muscle cells (VSMCs) accelerates manifestation of plaque vulnerability in atherosclerosis. Long noncoding RNA NEAT1 participates in the proliferation and apoptosis of cells. In addition, circadian clock genes play a significant role in cell apoptosis. However, whether acrolein, an environmental pollutant, affects the apoptosis of VSMCs by regulating NEAT1 and clock genes is still elusive. We established VSMCs as an atherosclerotic cell model in vitro. Acrolein exposure reduced survival rate of VSMCs, and raised apoptosis percentage through upregulating the expression of Bax, Cytochrome c and Cleaved caspase-3 and downregulating Bcl-2. Asparagus extract (AE), as a dietary supplementation, was able to protect VSMCs against acrolein-induced apoptosis. Expression of NEAT1, Bmal1 and Clock was decreased by acrolein, while was ameliorated by AE. Knockdown of NEAT1, Bmal1 or Clock promoted VSMCs apoptosis by regulating Bax, Bcl-2, Cytochrome c and Caspase-3 levels. Correspondingly, overexpression of NEAT1 inhibited the apoptosis. We also observed that silence of NEAT1 repressed the expression of Bmal1/Clock and vice versa. In this study, we demonstrated that VSMCs apoptosis induced by acrolein was associated with downregulation of NEAT1 and Bmal1/Clock. AE alleviated the effects of proapoptotic response and circadian disorders caused by acrolein, which shed a new light on cardiovascular protection.

[PMID: 31734579 DOI: 10.1016/j.biopha.2019.109248] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Revised: 07/18/2019] [Accepted: 07/18/2019] [Indexed: 12/12/2022] Open
Abstract
LncRNA NEAT1 is reported as a crucial oncogene in multiple cancers. But, its biological role in bladder cancer is barely understood. Therefore, we concentrated on the function and role of NEAT1 in bladder cancer. Firstly, NEAT1 expression in bladder cancer cells was determined and it was displayed NEAT1 was significant elevated. NEAT1 was knockdown and overexpressed in T24 and J82 cells. Then it was indicated that NEAT1 silence greatly inhibited bladder cancer cell proliferation with an increased ratio of apoptotic cells and severe cell cycle arrest. Overexpression of NEAT1 exhibited a reversed process in bladder cancer cells. Additionally, in vivo experiments were employed using establishment of nude mice models. NEAT1 knockdown inhibited bladder cancer growth while increase of NEAT1 promoted bladder cancer development in vivo. By employing the bioinformatics analysis, we speculated that miR-410 was as a downstream target of NEAT1. Then, the targeting association between them was proved in our research and we implicated miR-410 was dramatically restrained in bladder cancer cells. Meanwhile, it was exhibited that miR-410 was negatively regulated by NEAT1. Apart from these, HMGB1 was speculated as a downstream target of miR-410. Dual-luciferase reporter assay was used to prove the correlation between miR-410 and HMGB1. Up-regulation of miR-410 restrained HMGB1 levels and NEAT1 can regulate HMGB1 level via sponging miR-410. To sum up, we implied NEAT1/miR-410/HMGB1 axis participated in bladder cancer.

Abstract
Evidence has accumulated demonstrating that long noncoding RNAs (lncRNAs) participate in the initiation and progression of cancers. In this study, we found that the lncRNA nuclear paraspeckle assembly transcript 1 (NEAT1) is significantly increased in both cervical cancer tissues and cell lines. Overexpression of NEAT1 promoted the proliferation and migration of cervical cancer cells. Molecular studies uncovered that NEAT1 functions as competitive endogenous RNA (ceRNA), binding the micro-RNA miR-9-5p and suppressing its expression. However, we consistently found that when NEAT1 was highly expressed, it attenuated the inhibitory effect of miR-9-5p on the expression of PTEN and POU2F1, which are the targets of miR-9-5p. Consistent with the negative regulation of NEAT1 on miR-9-5p, restoration of miR-9-5p inhibited the growth-promoting effects of NEAT1 on cervical cancer cells. Taken together, these results indicated that NEAT1 plays an important role in the regulation cervical cancer cell growth by targeting miR-9-5p. Our findings characterized the possible mechanism of NEAT1 in cervical cancer.

Abstract
Nuclear paraspeckle assembly transcript 1 (NEAT1) has been found to be dysregulated and associated with clinical progression in various human cancers. The clinical and prognostic value of NEAT1 in nasopharyngeal carcinoma (NPC) was still controversial. The aim of our study was to provide more sufficient evidence that NEAT1 expression is correlated with overall survival in patients with NPC. NEAT1 expression was detected in NPC tissue samples, and the relationship between NEAT1 expression and clinical parameters, including prognosis, was analyzed. The meta-analysis was performed to further assess the prognostic significance of NEAT1 expression in patients with NPC. In our study, we found that the levels of NEAT1 expression were increased in NPC clinical tissue specimens, and associated with advanced M classification and clinical stages. Moreover, the Kaplan-Meier analysis suggested that the levels of NEAT1 expression were negatively associated with the overall survival of patients with NPC. Furthermore, univariate and multivariate Cox regression analyses showed that NEAT1 high-expression was an independent unfavorable prognostic factor in patients with NPC. Finally, we conducted a meta-analysis including 297 patients with NPC from the three studies, and found the pooled HR (95% confidence interval [CI]) was 1.64 (95% CI: 0.68-3.93) for the random effects model and 2.04 (95% CI: 1.42-2.95) for the fixed effect model. In conclusion, NEAT1 is a potential prognostic biomarker for NPC, but more studies are needed to further verify the prognostic value of NEAT1 in patients with NPC.

The long non-coding RNA NEAT1 is elevated in polyglutamine repeat expansion diseases and protects from disease gene-dependent toxicities. Hum Mol Genet 2018; 27:4303-4314. [PMID: 30239724 PMCID: PMC6276831 DOI: 10.1093/hmg/ddy331] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Revised: 09/11/2018] [Accepted: 09/13/2018] [Indexed: 12/28/2022] Open
Abstract
Polyglutamine (polyQ) repeat diseases are a class of neurodegenerative disorders caused by CAG-repeat expansion. There are diverse cellular mechanisms behind the pathogenesis of polyQ disorders, including transcriptional dysregulation. Interestingly, we find that levels of the long isoform of nuclear paraspeckle assembly transcript 1 (Neat1L) are elevated in the brains of mouse models of spinocerebellar ataxia types 1, 2, 7 and Huntington's disease (HD). Neat1L was also elevated in differentiated striatal neurons derived from HD knock-in mice and in HD patient brains. The elevation was mutant Huntingtin (mHTT) dependent, as knockdown of mHTT in vitro and in vivo restored Neat1L to normal levels. In additional studies, we found that Neat1L is repressed by methyl CpG binding protein 2 (MeCP2) by RNA-protein interaction but not by occupancy of MeCP2 at its promoter. We also found that NEAT1L overexpression protects from mHTT-induced cytotoxicity, while reducing it enhanced mHTT-dependent toxicity. Gene set enrichment analysis of previously published RNA sequencing data from mouse embryonic fibroblasts and cells derived from HD patients shows that loss of NEAT1L impairs multiple cellular functions, including pathways involved in cell proliferation and development. Intriguingly, the genes dysregulated in HD human brain samples overlap with pathways affected by a reduction in NEAT1, confirming the correlation of NEAT1L and HD-induced perturbations. Cumulatively, the role of NEAT1L in polyQ disease model systems and human tissues suggests that it may play a protective role in CAG-repeat expansion diseases.

Abstract
Accumulating evidence has indicated the significant roles of long noncoding RNAs (lncRNAs) in the pathophysiology of diabetic nephropathy (DN). LncRNA nuclear enriched abundant transcript 1 (NEAT1) has been reported to exert a key role in the progression of several diseases including diabetes. However, the role of NEAT1 in the regulation of DP progression remains barely known. Therefore, our study aimed to investigate the role of NEAT1 in a streptozotocin-induced diabetes model (DM) of rats and glucose-induced mouse mesangial cell models. Currently, we found that NEAT1 was greatly upregulated in DM rats and glucose-induced mice mesangial cells, in which a high activation of Akt/mTOR signaling was also observed. Then, it was shown that knockdown of NETA1 was able to reduce renal injury in DM rats obviously. In addition, cell counting kit-8 assay and 5-ethynyl-2'-deoxyuridine assay were carried out and we observed downregulation of NEAT1 significantly inhibited mesangial cell proliferation. Meanwhile, extracellular matrix proteins and messenger RNA (transforming growth factor β1, fibronectin, and collagen IV) expression was dramatically restrained by silencing of NEAT1 in the high glucose-induced mesangial cells. Finally, knockdown of NEAT1 greatly reduced the expression of the phosphorylation of Akt and mammalian target of rapamycin (mTOR) in vitro. These findings revealed that the decrease of NEAT1 repressed the proliferation and fibrosis in DN via activating the Akt/mTOR signaling pathway, which might represent a novel pathological mechanism of DN progression.

Abstract
Altered expression levels of the long noncoding RNA (lncRNA) nuclear‐enriched abundant transcript 1 (NEAT1) have been reported in different types of cancer. More than half of the NEAT1 studies in cancer have been published within the last 2 years. In this review, we discuss very recent developments and insights into NEAT1 contribution to carcinogenesis. Summarizing the literature, it becomes obvious that NEAT1 is a lncRNA highly de‐/upregulated in a variety of cancer entities, in which it primarily acts as a competing endogenous RNA (ceRNA) which sponges tumor‐suppressive microRNA (miRNA). The sponged miRNA lose their ability to degrade, silence, or hamper translation of their downstream—mostly oncogenic—target transcripts, ultimately promoting carcinogenesis. This role of NEAT1 function in tumorigenesis suggests it may be a prognostic biomarker as well as potential therapeutic target, pending the completion of further studies into the underlying mechanisms.

Abstract
Background Liver cancer is a type of malignant tumor with high morbidity and mortality in People’s Republic of China. Its occurrence and development involve the variation and expression changes of multiple genes, and the pathogenesis and related regulatory networks are complex. Purpose In the present research, we investigate the involvement of NEAT1_2 and SFPQ in cisplatin resistance in liver cancer. The effects of LncRNA NEAT1 and SFPQ expression on the chemotherapeutic resistance of liver cancer cells were analyzed. Methods The expression level of NEAT1_2 and SFPQ mRNA in tissue specimens or cell lines were examined by RT-qPCR and western blotting. CCK-8 assay was performed to evaluate cell viability. Cell proliferation was performed using the EdU cell proliferation assay. Results Our data showed that increase NEAT1_2 and SFPQ expressions in liver cancer specimens were associated with the development of cisplatin resistance; high SFPQ expression level impaired patients’ survival from liver cancer. Gain-and loss-of function assay using NEAT1_2 knock-in and knock-out cells constructed using CRISPER/Cas9 system revealed that NEAT1_2 is essential for liver cancer cell survival and mediates cisplatin resistance in liver cancer cells at least partially through SFPQ. Artificial change in NEAT1_2 expression level didn’t significantly influence SFPQ transcription or translation level. Conclusion Our data revealed NEAT1_2—SFPQ axis as a novel cisplatin resistance mechanism in liver cancer cells in vitro.

Abstract
RNA-protein interactions are integral to the regulation of gene expression. RNAs have diverse functions and the protein interactomes of individual RNAs vary temporally, spatially, and with physiological context. These factors make the global acquisition of individual RNA-protein interactomes an essential endeavor. Although techniques have been reported for discovery of the protein interactomes of specific RNAs they are largely laborious, costly, and accomplished singly in individual experiments. We developed HyPR-MS for the discovery and analysis of the protein interactomes of multiple RNAs in a single experiment while also reducing design time and improving efficiencies. Presented here is the application of HyPR-MS to simultaneously and selectively isolate the interactomes of lncRNAs MALAT1, NEAT1, and NORAD. Our analysis features the proteins that potentially contribute to both known and previously undiscovered roles of each lncRNA. This platform provides a powerful new multiplexing tool for the efficient and cost-effective elucidation of specific RNA-protein interactomes.

Abstract
Long non‐coding RNA (lncRNA) are extensively involved in various malignant tumors, including ovarian cancer (OC). In the present study, we focused on the expression and function of nuclear enriched abundant transcript 1 (NEAT1) in OC cells’ metastasis. We demonstrated that NEAT1 was upregulated in OC tissue specimens and cell lines. In addition, we revealed that depression of NEAT1 inhibited OC cells’ metastasis and the expression of Rho associated coiled‐coil containing protein kinase 1 (ROCK1), which is a metastasis‐related gene. Using online predictive software and a series of luciferase assays, we demonstrated that both NEAT1 and ROCK1 were the targets of microRNA‐382‐3p (miR‐382‐3p) and share similar microRNA responding elements (MRE). Furthermore, we illustrated that NEAT1 and miR‐382‐3p inhibited each other in a reciprocal manner. Finally, through antisense experiments we demonstrated that NEAT1 promoted ROCK1‐mediated metastasis by functioning as a ceRNA of miR‐382‐3p. In summary, the findings of this study revealed that NEAT1 promoted OC cells’ metastasis through regulating the miR‐382‐3p/ROCK1 axial. The present study might provide a new target for treating OC.

Abstract
Cells respond to pathophysiological states by activation of stress-induced signalling. Regulatory non-coding microRNAs (miRNAs) often form stable feed-forward loops which ensure prolongation of the signal, contributing to sustained activation. Members of the annexin protein family act as sensors for Ca2+, pH, and lipid second messengers, and regulate various signalling pathways. Recently, annexins were reported to participate in feedback loops, suppressing miRNA synthesis and attenuating stress-induced dysregulation of gene expression. They can directly or indirectly associate with RNAs, and are transferred between the cells in exosomes and shed microvesicles. The ability of annexins to recruit other proteins and miRNAs into exosomes implicates them in control of cell–cell interactions, affecting the adaptive responses and remodelling processes during disease. The studies summarized in this Review point to an emerging role of annexins in influencing the synthesis, localisation, and transfer of regulatory RNAs.
