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

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

Matrix metalloproteinases(MMPs)are essential enzymes involved in extracellular matrix degradation and remodeling.Such processes are integral to normal tissue homeostasis and several pathological conditions such as cancer.Among these MMPs,MMP-13 plays a key role in cancer progression,driving tumor invasion,metastasis,and angiogenesis.Despite significant advancements in understanding its biology,therapeutic targeting of MMP-13 remains challenging owing to its complex and multifaceted regulatory mechanisms.Recent studies have underscored the pivotal role of non-coding RNAs(ncRNAs),including long ncRNAs,microRNAs,and circular RNAs,in modulating MMP-13 expression.This review provides a comprehensive analysis of MMP-13 regulation by several signaling pathways,the influence of ncRNAs on these signaling pathways,and MMP-13 expression during cancer progression and metastasis.Furthermore,we explored the clinical relevance of ncRNA-mediated regulatory networks,highlighting their potential as diagnostic biomarkers and therapeutic targets in various cancers.By unraveling these regulatory mechanisms,this review offers valuable insights into innovative strategies for cancer diagnosis and treatment and emphasizes the translational significance of ncRNA-mediated MMP-13 regulation in oncology. 展开更多

Spinal cord injury(SCI),either from trauma or degenerative changes,can res ult in severe disability and impaired quality of life.Understanding the cellular processes and molecular mechanisms that underlie SCI is imperative to identifying molecular targets for potential therapy.Recent studies have shown that non-coding RNAs,including both long non-coding RNAs(lncRNAs)and circular RNAs(circRNAs),regulate various cellular processes in SCI.In this review,we will describe the changes in lncRNA and circRNA expression that occur after SCI and how these changes may be related to SCI progression.Current evidence for the roles of lncRNAs and circRNAs in neuronal cell death and glial cell activation will also be reviewed.Finally,the possibility that lncRNAs and circRNAs are novel modulato rs of SCI pathogenesis will be discussed. 展开更多

Diabetic foot ulcer(DFU)and poor wound healing are chronic complications in patients with diabetes.The increasing incidence of DFU has resulted in huge pressure worldwide.Diagnosing and treating this condition are therefore of great importance to control morbidity and improve prognosis.Finding new markers with potential diagnostic and therapeutic utility in DFU has gathered increasing interest.Wound healing is a process divided into three stages:Inflammation,proliferation,and regeneration.Non-coding RNAs(ncRNAs),which are small protected molecules transcribed from the genome without protein translation function,have emerged as important regulators of diabetes complications.The deregulation of ncRNAs may be linked to accelerated DFU development and delayed wound healing.Moreover,ncRNAs can be used for therapeutic purposes in diabetic wound healing.Herein,we summarize the role of microRNAs,long ncRNAs,and circular RNAs in diverse stages of DFU wound healing and their potential use as novel therapeutic targets. 展开更多

Circular RNAs(circRNAs)are a type of non coding RNA that possess unique single stranded circular structures formed through reverse splicing mechanisms.Due to the lack of a free end that is typically susceptible to degradation by nucleases,circular RNAs exhibit resistance to ribonuclease R,making them highly stable in eukaryotic cells.The complex relationship between circRNA dysregulation and various pathophysiological conditions,especially cancer.Tumor microenvironment(TME)is a collective term for various components surrounding tumors and is an important factor affecting tumor development.Simultaneous infiltration of TME by different types of immune cells;These immune cells interact with the TME,collectively forming the so-called“tumor immune microenvironment”.The complex interactions between tumor cells and TME profoundly affect the behavior of malignant tumors,and circRNAs derived from tumor cells and TME cell components have become important mediators of immune response and evasion within the TME.CircRNAs can directly or indirectly regulate immune cells,thereby modulating anti-tumor immunity.This review highlights how circRNAs,especially those encapsulated in extracellular vesicles like exosomes,influence the differentiation,chemotaxis,and anti-tumor immune functions of immune cells within the TME.Metabolic reprogramming plays an important role in this process.The process of circRNAs regulating tumor immunity is affected by multiple factors,such as hypoxia and viral infection.This review emphasizes the roles of the interaction between circRNAs and the TME in tumor immune regulation and prospects the guiding significance of circRNAs in tumor immune checkpoint therapy. 展开更多

Circular RNAs(circRNAs)are formed by splicing of precursor RNAs and covalently linked at the 5′and 3′ends.Dysregulated circRNAs are closely related to the epithelial-mesenchymal transition(EMT)of gastrointestinal malignancies.CircRNAs,including circRNA_0008717,circGOT1,circ-DOCK5,circVPS33B,circPVT1,circMET,circ-OXCT1,circ_67835,circRTN4,circ_0087502,circFNDC38,circ_PTEN1,circPGPEP1,and circ-E-Cad are involved in the EMT process of gastrointestinal malignancies through a variety of mechanisms,such as regulating EMT-inducing transcription factors,signaling pathways,and tumor microenvironments.Gastrointestinal(GI)malignancies are common malignant tumors worldwide,and the heterogeneity and easy metastasis of gastrointestinal malignancies limit the effectiveness of medical treatments.Therefore,investigating the molecular mechanisms involved in the pathogenesis of gastrointestinal malignancies is essential for clinical treatment.This article summarizes the biological roles and molecular mechanism of circRNAs in EMT of gastrointestinal malignancies,providing a theoretical basis for applying EMT-related circRNAs in targeted therapy. 展开更多

This review aims to sum up how Non-coding RNAs(ncRNAs)regulate the development of periodontitis and provides a new perspective for understanding the pathogenesis of periodontitis.We explored the ncRNA's dual role in the development of periodontitis by summarizing evidence from previous in vivo and in vitro studies as well as clinical samples.In our review,the downregulation of 18 miRNAs,22 lncRNAs and 10 circRNAs demonstrates protective roles in periodontitis.In contrast,the expression of other 11 miRNAs,7 lncRNAs and 6 circRNAs are upregulated in periodontitis,which promote the progression of periodontitis.These dysregulated ncRNAs exert their protective or destructive roles by mainly influencing cell proliferation,differentiation and apoptosis via cross-talking with various molecules or signaling pathways.Our findings suggested which and how ncRNAs promote or delay the progression of periodontitis,which may greatly contribute to diagnose and therapy development of periodontitis based on ncRNAs in the future. 展开更多

Hepatic ischemia-reperfusion injury(HIRI)is the major complication of liver surgery and liver transplantation,that may increase the postoperative morbidity,mortality,tumor progression,and metastasis.The underlying mechanisms have been extensively investigated in recent years.Among these,oxidative stress,inflammatory responses,immunoreactions,and cell death are the most studied.Non-coding RNAs(ncRNAs)are defined as the RNAs that do not encode proteins,but can regulate gene expressions.In recent years,ncRNAs have emerged as research hotspots for various diseases.During the progression of HIRI,ncRNAs are differentially expressed,while these dysregulations of ncRNAs,in turn,have been verified to be related to the above pathological processes involved in HIRI.ncRNAs mainly contain microRNAs,long ncRNAs,and circular RNAs,some of which have been reported as biomarkers for early diagnosis or assessment of liver damage severity,and as therapeutic targets to attenuate HIRI.Here,we briefly summarize the common pathophysiology of HIRI,describe the current knowledge of ncRNAs involved in HIRI in animal and human studies,and discuss the potential of ncRNA-targeted therapeutic strategies.Given the scarcity of clinical trials,there is still a long way to go from pre-clinical to clinical application,and further studies are needed to uncover their potential as therapeutic targets. 展开更多

Osteosarcoma is one of the most genomically complex cancers and as result,it has been difficult to assign genomic aberrations that contribute to disease progression and patient outcome consistently across samples.One potential source for correlating osteosarcoma and genomic biomarkers is within the non-coding regions of RNA that are differentially expressed.However,it is unsurprising that a cancer classification that is fraught with genomic instability is likely to have numerous studies correlating non-coding RNA expression and function have been published on the subject.This review undertakes the formidable task of evaluating the published literature of noncoding RNAs in osteosarcoma.This is not the first review on this topic and will certainly not be the last.The review is organized with an introduction into osteosarcoma and the epigenetic control of gene expression before reviewing the molecular function and expression of long non-coding RNAs,circular RNAs,and short non-coding RNAs such as microRNAs,piwi RNAs,and short-interfering RNAs.The review concludes with a review of the literature and how the biology of non-coding RNAs can be used therapeutically to treat cancers,especially osteosarcoma.We conclude that non-coding RNA expression and function in osteosarcoma is equally complex to understanding the expression differences and function of coding RNA and proteins;however,with the added lens of both coding and non-coding genomic sequence,researchers can begin to identify the patterns that consistently associate with aggressive osteosarcoma. 展开更多

Non-coding RNAs (ncRNAs) are a large class of transcripts lacking evident protein coding potential, and play versatile roles in a diverse range of physiological and pathological processes. Mounting evidences have indicated that ncRNAs are aberrantly expressed in a wealth of diseases such as cataract. Cataract is a cloudy lens caused by radiation, age, drugs and other factors. NcRNAs, including microRNAs, long non-coding RNAs, circular RNAs, have been identified to regulate the occurrence and development of cataract. Current studies indicate that ncRNAs exert the multifaceted functions in the lens of cataract patients and have been proved as potential diagnostic biomarkers or therapeutic targets for cataracts. This review summarizes the study of relationship between the lens and ncRNAs, which can provide a novel insight into the pathogenesis of cataract. 展开更多
