Alzheimer's disease,a progressively degenerative neurological disorder,is the most common cause of dementia in the elderly.While its precise etiology remains unclear,researchers have identified diverse pathological characteristics and molecular pathways associated with its progression.Advances in scientific research have increasingly highlighted the crucial role of non-coding RNAs in the progression of Alzheimer's disease.These non-coding RNAs regulate several biological processes critical to the advancement of the disease,offering promising potential as therapeutic targets and diagnostic biomarkers.Therefore,this review aims to investigate the underlying mechanisms of Alzheimer's disease onset,with a particular focus on microRNAs,long non-coding RNAs,and circular RNAs associated with the disease.The review elucidates the potential pathogenic processes of Alzheimer's disease and provides a detailed description of the synthesis mechanisms of the three aforementioned non-coding RNAs.It comprehensively summarizes the various non-coding RNAs that have been identified to play key regulatory roles in Alzheimer's disease,as well as how these noncoding RNAs influence the disease's progression by regulating gene expression and protein functions.For example,miR-9 targets the UBE4B gene,promoting autophagy-mediated degradation of Tau protein,thereby reducing Tau accumulation and delaying Alzheimer's disease progression.Conversely,the long non-coding RNA BACE1-AS stabilizes BACE1 mRNA,promoting the generation of amyloid-βand accelerating Alzheimer's disease development.Additionally,circular RNAs play significant roles in regulating neuroinflammatory responses.By integrating insights from these regulatory mechanisms,there is potential to discover new therapeutic targets and potential biomarkers for early detection and management of Alzheimer's disease.This review aims to enhance the understanding of the relationship between Alzheimer's disease and non-coding RNAs,potentially paving the way for early detection and novel treatment strategies. 展开更多

Genomic destabilization and defective DNA repair are the most prominent features of tumour cells and are exploited by various chemotherapy drugs for cancer therapy.Long non-coding RNA(lncR-NAs)have emerged as powerful regulators of gene expression and are thus involved in diverse biological processes.Recent studies have demonstrated that several lncRNAs play critical roles in DNA repair.Nonetheless,the relationship between DNA damage-responsive lncRNAs and chemoresistance remains poorly defined.In this study,we established four different DNA damage models triggered by cisplatin(DDP),H2O2,neocarzinostatin(NCS)or ultraviolet(UV)irradiation and identified a specific upregu-lated lncRNA(lnc-DUSP6)involved in the cisplatin-induced DNA damage response.Furthermore,loss-or gain-of-function experiments confirmed that lnc-DUSP6 enhanced DNA repair and cell survival under cisplatin treatment,thus promoting cisplatin resistance.Mechanistically,an RNA immunoprecipitation(RIP)assay revealed that lnc-DUSP6 directly interacts with DUSP6(Dual Specificity Phosphatase 6),which is closely associated with cisplatin sensitivity.Additionally,overexpression of DUSP6 significantly rescued the effects of lnc-DUSP6 silencing on DNA repair and cell survival under cisplatin treatment.O-verall,our results show the effect and underlying mechanism of lnc-DUSP6 in cisplatin resistance:lnc-DUSP6 promotes cisplatin-induced DNA damage repair and cisplatin resistance by stabilizing DUSP6,which is highly clinically important for enhancing the efficacy of cisplatin for cancers. 展开更多

Gastric cancer(GC)has high morbidity and mortality worldwide.Due to the absence of noticeable symptoms,diagnosing GC at an early stage is very difficult,which consequently leads to advanced GC and poor prognosis.Effective biomarkers are essential for prolonging patients’survival.Helicobacter pylori(H.pylori)infection represents the most significant risk factor for GC,with nearly all cases linked to this infection.Many non-coding RNAs(ncRNAs)are dysregulated in H.pylori-infected GC,indicating that ncRNAs may serve as biomarkers of early-stage GC.In this editorial,we discuss the study by Chen et al.Although previous studies have identified roles for miR-136 in gastric cancer proliferation,apoptosis,and invasion,none have specifically explored its relationship with H.pylori-associated gastric carcinogenesis. 展开更多

A large body of evidence has highlighted the role of non-coding RNAs in neurodevelopment and neuroinflammation.This evidence has led to increasing speculation that non-coding RNAs may be involved in the pathophysiological mechanisms underlying hydrocephalus,one of the most common neurological conditions worldwide.In this review,we first outline the basic concepts and incidence of hydrocephalus along with the limitations of existing treatments for this condition.Then,we outline the definition,classification,and biological role of non-coding RNAs.Subsequently,we analyze the roles of non-coding RNAs in the formation of hydrocephalus in detail.Specifically,we have focused on the potential significance of non-coding RNAs in the pathophysiology of hydrocephalus,including glymphatic pathways,neuroinflammatory processes,and neurological dysplasia,on the basis of the existing evidence.Lastly,we review the potential of non-coding RNAs as biomarkers of hydrocephalus and for the creation of innovative treatments. 展开更多

Anther is a key male reproductive organ that is essential for the plant life cycle,from the sporophyte to the gametophyte generation.To explore the isoform-level transcriptional landscape of developing anthers in maize(Zea mays L.),we analyzed Iso-Seq data from anthers collected at 10 developmental stages,together with strand-specific RNA-seq,CAGE-seq,and PAS-seq data.Of the 152,026 high-confidence full-length isoforms identified,68.8%have not been described;these include 22,365 isoforms that originate from previously unannotated loci and 82,167 novel isoforms that originate from annotated protein-coding genes.Using our newly developed strategy to detect dynamic expression patterns of isoforms,we identify 13,899 differentially variable regions(DVRs);surprisingly,1275 genes contain more than two DVRs,revealing highly efficient utilization of limited genic regions.We identify 7876 long non-coding RNAs(lncRNAs)from 4098 loci,most of which were preferentially expressed during cell differentiation and meiosis.We also detected 371 long-range interactions involving intergenic lncRNAs(lincRNAs);interestingly,243 were lincRNA-gene ones,and the interacting genes were highly expressed in anthers,suggesting that many potential lncRNA regulators of key genes are required for anther development.This study provides valuable resources and fundamental information for studying the essential transcripts of key genes during anther development. 展开更多

Flavonoids,abundant in the fruits,are pivotal to their growth,development,and storage.In addition,they have significant beneficial effects on human health.Consequently,research is increasingly concentrating on the regulatory mechanisms governing flavonoid biosynthesis in fruits.Phytohormones are involved in the regulation of flavonoid biosynthesis.The abscisic acid,ethylene,jasmonic acid,cytokinins,and brassinosteroids promote flavonoid biosynthesis,while auxin negatively regulates flavonoid biosynthesis.Subsequently,transcription factors from the MYB,bHLH,WRKY,NAC,and bZIP families are pivotal in regulating flavonoid biosynthesis.In addition,non-coding RNAs(microRNA and lncRNA)also participate in the regulation of flavonoids biosynthesis.MicroRNAs are generally believed to negatively regulate flavonoid metabolism in fruits,while lncRNAs have the opposite effect.Furthermore,the interactions between plant hormones,transcription factors,and non-coding RNAs in fruit flavonoid biosynthesis were analyzed.Ultimately,a foundational regulatory network for fruit flavonoid biosynthesis was hereby established. 展开更多

Hepatocellular carcinoma(HCC)remains one of the most prevalent and lethal malignancies worldwide.Long non-coding RNAs(lncRNAs)have emerged as crucial regulators of gene expression and cancer progression,yet the functional diversity of RP11-derived lncRNAs—originally mapped to bacterial artificial chromosome(BAC)clones from the Roswell Park Cancer Institute—has only recently begun to be appreciated.This mini-review aims to systematically synthesize current findings on RP11-derived lncRNAs in HCC,outlining their genomic origins,molecular mechanisms,and biological significance.We highlight their roles in metabolic reprogramming,microRNA network modulation,and tumor progression,as well as their diagnostic and prognostic value in tissue and serum-based analyses.Finally,we discuss therapeutic opportunities and propose future directions to translate RP11-derived lncRNAs into clinically actionable biomarkers and targets for precision liver cancer therapy. 展开更多

Alzheimer s disease is a progressive neurodegenerative disease chara cterized by memory decline and the accumulation of abnormal protein aggregates in the brain.While the precise cause of Alzheimer s disease remains under investigation,recent research suggests that dys regulation of brainspecific microRNAs(miRs)plays a significant role in Alzheimer s disease pathogenesis.Brain-specific miRs are predominantly expressed within the central nervous system and are crucial for neuronal development,and function,potentially in brain disorders.This review identifies some key brainspecific miRs in Alzheimer's disease,including miR-9,miR-26b,miR-34a,miR-107,miR-124,miR-125b,miR-128,miR-132,miR-146a,miR-155,miR-219,miR-501-3p,and miR-502-3p.The review also shed light on the brain-specific location of these miRs,their dysregulation in Alzheimer s disease,and how they are involved in disease progression.Apparently,these brain-specific miRs modulate specific genes and are therefo re crucial for various cellular processes,including autophagy,cell cycle,tau phosphorylation,amyloid-beta production,and neuroinflammation.Moreover,these miRs are potent disease-modifying factors and their expression levels co uld serve as potential biomarkers for diagnosing or monitoring Alzheimer s disease progression. 展开更多

This literature review explores the complex interaction between p53 and microRNAs(miRNAs)in the occurrence and progression of breast cancer(BC),the most common and lethal tumor type among women.BC is a multifactorial disease resulting from a combination of genetic and epigenetic alterations in cell DNA,influencing proliferation,differentiation,and migration.TP53 gene,which codifies p53 protein,is a known tumor suppressor,and it plays an important role in cell maintenance as DNA repair,cell proliferation control,and apoptosis activation.TP53 expression can be modulated by several miRNAs,as miR-30c,miR-34a,and the miR-200 family,inhibiting p53 production and silencing its tumor suppressor effects.On the other hand,p53 protein can modulate several miRNAs expression,as miR-146a,miR-192,and the miR-200 family,by acting as a transcription factor or by modulating miRNA processing,interfering with BC aggressiveness and progression.Understanding the role of p53 and miRNAs in BC may aid in identifying new biomarkers and developing new targeted therapies for patient treatment. 展开更多

Hepatocellular carcinoma(HCC)remains the third leading cause of cancer-related deaths worldwide;however,its therapeutic options are limited.Understanding the molecular mechanisms of HCC could provide insight into new therapies.Emerging studies indicate the important role of long-noncoding RNAs(lncRNAs)in the pathogenesis of HCC.The expression of the well-studied lncRNA taurine upregulated gene 1(TUG1)is upregulated in HCC tissues,but its transcriptomic effects in HCC cells remain unexplored.We established TUG1-knockdown and control HCC cells for RNA-seq experiments.KEGG analysis revealed glycolysis as the top enriched pathway upon TUG1 silencing.Accordingly,TUG1-depleted HCC cells showed impairments in glucose uptake,ATP synthesis,and lactate production.Clinical HCC tissue data revealed positive gene expression correlations between TUG1 and several glycolysis-related genes.To identify a molecular function of TUG1 in glycolysis,we explored the competing endogenous model and used bioinformatic tools to find the five microRNAs(miRNAs)that had the most binding sites for TUG1.Among these miRNAs,miR-122-5p exhibited an inverse correlation in gene expression with most TUG1-regulated glycolysis genes,including PKM,ALDOA,ENO2,and PFKM.Dual-luciferase assays demonstrated the direct interaction between TUG1 and miR-122-5p and between miR-122-5p and the 3ʹuntranslated regions of both PKM and ALDOA.We further showed that inhibition of miR-122-5p alleviated the suppression of glycolysis induced by TUG1 depletion.Together,our RNA-seq analysis of TUG1-depleted HCC cells,combined with clinical data,reveals a critical role of TUG1 in regulating glycolysis and provides new insight into its oncogenic function in HCC. 展开更多

Background:Hepatectomy and liver transplantation(LT)are the two most commonly performed surgical procedures for various hepatic lesions.micro RNA(mi RNA)and long non-coding RNA(lnc RNA)have been gradually unveiled their roles as either biomarkers for early diagnosis or potentially therapeutic tools to manipulate gene expression in many disease entities.This review aimed to discuss the effects of mi RNA or lnc RNA in the hepatectomy and LT fields.Data sources:We did a literature search from 1990 through January 2018 to summarize the currently available evidence with respect to the effects of mi RNA and lnc RNA in liver regeneration after partial hepatectomy,as well as their involvement in several key issues related to LT,including ischemia-reperfusion injury,allograft rejection,tolerance,recurrence of original hepatic malignancies,etc.Results:Certain mi RNAs and lnc RNAs are actively involved in the regulation of various aspects of liver resection and transplantation.During the process of liver regeneration after hepatectomy,the expression of mi RNAs and lnc RNAs shows dynamic changes.Conclusions:It is now clear that mi RNAs and lnc RNAs orchestrate in various aspects of the pathophysiological process of LT and hepatectomy.Better understanding of the underlying mechanism and future clinical trials may strengthen their positions as either biomarkers or potential therapeutic targets in the management of complications after liver surgery. 展开更多

Acute ischemic stroke is a clinical emergency and a condition with high morbidity,mortality,and disability.Accurate predictive,diagnostic,and prognostic biomarkers and effective therapeutic targets for acute ischemic stroke remain undetermined.With innovations in high-throughput gene sequencing analysis,many aberrantly expressed non-coding RNAs(ncRNAs)in the brain and peripheral blood after acute ischemic stroke have been found in clinical samples and experimental models.Differentially expressed ncRNAs in the post-stroke brain were demonstrated to play vital roles in pathological processes,leading to neuroprotection or deterioration,thus ncRNAs can serve as therapeutic targets in acute ischemic stroke.Moreover,distinctly expressed ncRNAs in the peripheral blood can be used as biomarkers for acute ischemic stroke prediction,diagnosis,and prognosis.In particular,ncRNAs in peripheral immune cells were recently shown to be involved in the peripheral and brain immune response after acute ischemic stroke.In this review,we consolidate the latest progress of research into the roles of ncRNAs(microRNAs,long ncRNAs,and circular RNAs)in the pathological processes of acute ischemic stroke–induced brain damage,as well as the potential of these ncRNAs to act as biomarkers for acute ischemic stroke prediction,diagnosis,and prognosis.Findings from this review will provide novel ideas for the clinical application of ncRNAs in acute ischemic stroke. 展开更多

MicroRNA(miRNA)是植物中重要的内源性非编码小RNA,对植物次生代谢产物的形成起着至关重要的作用。现阶段,人们关于miRNA如何调节茶树紫色芽叶形成机制的了解仍不充分。以常规茶树品种云抗10号、紫色芽叶茶树品种紫娟为研究对象,构建6个小RNA文库和2个混池的降解组文库。通过测序分析,共鉴定出2651个miRNA,包括403个已知miRNA和2248个新鉴定的miRNA。表达分析结果显示,在云抗10号和紫娟之间,有112个miRNA的表达水平存在显著差异,其中25个是已知miRNA,87个是新预测的miRNA。上述结果表明,研究中鉴定获得的新预测的miRNA可能参与紫娟茶树花青素的积累。通过对降解组进行测序分析,共筛选获得112个差异miRNA的441个靶基因,这些靶基因包括48个转录因子(包括21个MYB家族基因、20个SBP家族基因和2个TCP家族基因),其中有多个转录因子已被报道参与茶树类黄酮代谢。miRNA靶基因的KEGG富集结果显示,花青素合成途径、类黄酮合成途径和苯丙烷类生物合成途径被富集,这3个途径共包括7个功能基因,说明miRNA除了通过调控转录因子编码基因,还可能通过靶向这些功能基因来调控紫娟花青素的积累。研究鉴定出参与紫娟紫色芽叶形成的关键miRNA及靶基因,为揭示茶树花青素合成的转录后调控机制提供了理论依据。 展开更多

目的:采用孟德尔随机化(MR)方法探究microRNAs与肺腺癌(LUAD)致病风险之间的因果关系。方法:使用miR-eQTL数据和肺腺癌全基因组关联研究(GWAS)数据集,运用逆方差加权法(IVW)、MR Egger以及加权中位数法等3种孟德尔随机化方法,系统评估mi... 目的:采用孟德尔随机化(MR)方法探究microRNAs与肺腺癌(LUAD)致病风险之间的因果关系。方法:使用miR-eQTL数据和肺腺癌全基因组关联研究(GWAS)数据集,运用逆方差加权法(IVW)、MR Egger以及加权中位数法等3种孟德尔随机化方法,系统评估microRNAs与LUAD之间的因果关联。进行Cochran s Q检验、MR Egger截距检验、MR-PRESSO和留一法等敏感性分析,评估MR结果的稳健性。对IVW结果进行Meta分析,筛选更稳健的microRNAs,通过预测其靶基因和功能富集分析,解析致病microRNAs在肺腺癌中的潜在作用。结果:筛选出3个重要microRNAs和LUAD存在因果关系,包括hsa-miR-27b-3p(OR=1.08,95%CI 1.03~1.13)、hsa-miR-130a-3p(OR=1.11,95%CI 1.08~1.14)和hsa-miR-196b-5p(OR=1.06,95%CI 1.02~1.10)。GO功能分析显示,致病microRNAs的预测靶点在细胞代谢、细胞生长等途径中显著富集,KEGG通路分析表明其在MAPK、TGF-β信号通路中显著富集。结论:鉴定出3个关键microRNAs(hsa-miR-27b-3p、hsa-miR-130a-3p、和hsa-miR-196b-5p),其表达调控可能在LUAD发生发展中发挥因果作用,这3个microRNAs的高表达是LUAD的危险因素。本研究提出的分析框架有助于理解microRNAs在LUAD发生发展中的作用,为临床应用提供了潜在的生物标志物。 展开更多
