Emerging evidence indicates that lnc RNAs may play important regulatory roles in the pathogenesis and progression of human cancers, including hepatocellular carcinoma(HCC). Certain lnc RNAs may be used as diagnostic or prognostic markers for HCC, a serious malignancy with increasing morbidity and high mortality rates worldwide. Therefore, elucidating the functional roles of lnc RNAs in tumors can contribute to a better understanding of the molecular mechanisms of HCC and may help in developing novel therapeutic targets. In this review, we summarize the recent progress regarding the functional roles of lnc RNAs in HCC and explore their clinical implications as diagnostic or prognostic biomarkers and molecular therapeutic targets for HCC.展开更多

文摘The treatment of complex wounds presents a significant clinical challenge due to the limited availability of standardized therapeutic options.Adipose-derived stem cell exosomes(ADSC-Exos)are promising for their capabilities to enhance angiogenesis,mitigate oxidative stress,modulate inflammatory pathways,support skin cell regeneration,and promote epithelialization.These exosomes deliver noncoding RNAs,including microRNAs,long non-coding RNAs,and circular RNAs,which facilitate collagen remodeling,reduce scar formation,and expedite wound healing.This study reviews the mechanisms,therapeutic roles,and challenges of non-coding RNA-loaded ADSC-Exos in wound healing and identifies critical directions for future research.It aims to provide insights for researchers into the potential mechanisms and clinical applications of ADSC-Exos non-coding RNAs in wound healing.
文摘Colorectal cancer(CRC)remains a formidable global health challenge and is associated with dismal survival outcomes and high mortality among patients diagnosed at advanced stages.Despite advancements in early screening and therapeutic interventions,the outcomes of patients with advanced-stage CRC remain suboptimal,as these patients continue to exhibit a persistently low 5-year survival rate.Palliative radiotherapy(RT)is crucial for advanced CRC patients,but radioresistance remains a significant clinical challenge.This resistance is attributed to multiple mechanisms,such as genetic heterogeneity,dysregulated DNA damage repair and tumor microenvironment metabolic disorders.Recent studies have shown that noncoding RNAs(ncRNAs),mainly microRNAs,long ncRNAs(lncRNAs)and circular RNAs,play pivotal roles in regulating CRC radiosensitivity through diverse mechanisms,such as epithelial-mesenchymal transition,epigenetic reprogramming,posttranscriptional regulation and oncogenic signaling pathway activation.For example,microRNAs such as miR-141-3p and miR-630 enhance CRC radiosensitivity by targeting oncogenic pathways.In addition,lncRNAs,including the lncRNAs HOTAIR and LINC00630,influence the radiosensitivity of CRC through interactions with the DNA damage repair machinery and epigenetic modulators,respectively.In addition,circ_0124554 acts as a competitive endogenous RNA to regulate oncogenic signaling.ncRNAs also serve as potential biomarkers for predicting radiosensitivity and prognosis.This review synthesizes the current evidence on the ncRNA-mediated regulatory networks that influence CRC radiosensitivity,emphasizing their potential as therapeutic targets to overcome RT resistance and improve outcomes in advanced CRC.By bridging mechanistic insights with clinical applications,this work aims to guide future research and the implementation of precision RT strategies.

文摘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.
文摘Ischemic stroke occurs under a variety of clinical conditions and has different pathogeneses,resulting in necrosis of brain parenchyma.Stroke pathogenesis is characterized by neuroinflammation and endothelial dysfunction.Some of the main processes triggered in the early stages of ischemic damage are the rapid activation of resident inflammatory cells(microglia,astrocytes and endothelial cells),inflammatory cytokines,and translocation of intercellular nuclear factors.Inflammation in stroke includes all the processes mentioned above,and it consists of either protective or detrimental effects concerning the“polarization”of these processes.This polarization comes out from the interaction of all the molecular pathways that regulate genome expression:the epigenetic factors.In recent years,new regulation mechanisms have been cleared,and these include non-coding RNAs,adenosine receptors,and the activity of mesenchymal stem/stromal cells and microglia.We reviewed how long non-coding RNA and microRNA have emerged as an essential mediator of some neurological diseases.We also clarified that their roles in cerebral ischemic injury may provide novel targets for the treatment of ischemic stroke.To date,we do not have adequate tools to control pathophysiological processes associated with stroke.Our goal is to review the role of non-coding RNAs and innate immune cells(such as microglia and mesenchymal stem/stromal cells)and the possible therapeutic effects of their modulation in patients with acute ischemic stroke.A better understanding of the mechanisms that influence the“polarization”of the inflammatory response after the acute event seems to be the way to change the natural history of the disease.

文摘Long non-coding RNAs(lnc RNAs) are a subgroup of non-coding RNA transcripts greater than 200 nucleotides in length with little or no protein-coding potential. Emerging evidence indicates that lnc RNAs may play important regulatory roles in the pathogenesis and progression of human cancers, including hepatocellular carcinoma(HCC). Certain lnc RNAs may be used as diagnostic or prognostic markers for HCC, a serious malignancy with increasing morbidity and high mortality rates worldwide. Therefore, elucidating the functional roles of lnc RNAs in tumors can contribute to a better understanding of the molecular mechanisms of HCC and may help in developing novel therapeutic targets. In this review, we summarize the recent progress regarding the functional roles of lnc RNAs in HCC and explore their clinical implications as diagnostic or prognostic biomarkers and molecular therapeutic targets for HCC.
