Competitive endogenous RNAs (ceRNAs) act as molecular sponges for microRNAs (miRNAs), and are associated with tumorigenesis in various cancers, including laryngeal cancer (LC). In this work, we constructed an LC-specific inflammatory gene-related ceRNA network (IceNet). In IceNet, ceRNAs targeting inflammation-related genes tended to be network hubs. Additionally, the betweenness centralities of these hub ceRNAs were higher than those of the inflammation-related genes themselves, indicating that the hub ceRNAs in this study played critical roles in communication between IceNet molecules...

Acute myocardial infarction (AMI) is one of the most common cardiovascular diseases that leads to high mortality and morbidity globally. Various therapeutic targets for AMI have been investigated in recent years, including the non-coding RNAs (ncRNAs). NcRNAs, a class of RNA molecules that typically do not code proteins, are divided into several subgroups. Among them, microRNAs (miRNAs) are widely studied for their modulation of several pathological aspects of AMI, including cardiomyocyte apoptosis, inflammation, angiogenesis and fibrosis...

BACKGROUND: Long non-coding RNAs (lncRNAs) are known to play important roles in different cell contexts, including cancers. However, little is known about lncRNAs in cholangiocarcinoma (CCA), a cholangiocyte malignancy with poor prognosis, associated with chronic inflammation and damage to the biliary epithelium. The aim of the study is to identify if any lncRNA might associate with inflammation or oxidative stress in CCA and regulate the disease progression. METHODS: In this study, RNA-seqs datasets were used to identify aberrantly expressed lncRNAs...

Recently, long non-coding RNAs (lncRNAs) have emerged as critical players in gene regulation for multiple biological processes. However, their roles and functions in human adipose-derived stem cells (hASCs) differentiation remain unclear. In the present study, we investigated the role of lncRNA myocardial infarction-associated transcript (MIAT) in the osteogenic differentiation of hASCs. We found that the expression of MIAT was downregulated in a time-dependent manner during hASCs osteoinduction. MIAT knockdown promoted osteogenic differentiation of hASCs both in vitro and in vivo...

BACKGROUND: Psoriasis is an immune-mediated, inflammatory disorder of the skin characterized by chronic inflammation and hyperproliferation of the epidermis. Differential expression analysis of microarray or RNA-seq data have shown that thousands of coding and non-coding genes are differentially expressed between psoriatic and healthy control skin. However, differential expression analysis may fail to detect perturbations in gene coexpression networks. Sensitive detection of such networks may provide additional insight into important disease-associated pathways...

BACKGROUND/AIMS: Osteomyelitis is defined as an inflammation of the bones and bone marrow. The inflammatory microenvironment attenuates the osteogenic differentiation capacity of stem cells and inhibits osteoblast-mediated bone formation, leading to net bone loss. However, the whole expression profile, function and side effect of long non-coding RNAs (lncRNAs) on osteogenic differentiation of stem cells in an inflammatory microenvironment of osteomyelitis are not known. METHODS: In the present study, human bone mesenchymal stem cells (hBMSCs) were treated with different concentrations of Staphylococcal protein A (SpA) to trigger an inflammatory microenvironment in vitro to partly duplicate the inflammatory microenvironment of osteomyelitis, which was confirmed using ELISA for detecting the inflammatory cytokines...

Neutrophils, eosinophils and 'classical' monocytes collectively account for about 70% of human blood leukocytes and are among the shortest-lived cells in the body. Precise regulation of the lifespan of these myeloid cells is critical to maintain protective immune responses and minimize the deleterious consequences of prolonged inflammation. However, how the lifespan of these cells is strictly controlled remains largely unknown. Here we identify a long non-coding RNA that we termed Morrbid, which tightly controls the survival of neutrophils, eosinophils and classical monocytes in response to pro-survival cytokines in mice...

microRNA, a family of small non-coding RNA, plays significant roles in regulating gene expression, mainly via binding to the 3'-untranslated region of target genes. Although the role of miRNA in regulating neuroinflammation via the innate immune pathway has been studied, its role in the production of inflammatory mediators during microglial activation is poorly understood. In this study, we investigated the effect of miR-27a on lipopolysaccharide (LPS)-induced microglial inflammation. miR-27a expression was found to be rapidly decreased in microglia by real-time polymerase chain reaction (real-time PCR) after LPS stimulation...

Microvascular dysfunction is an important characteristic of diabetic retinopathy. Long non-coding RNAs (lncRNAs) play important roles in diverse biological processes. In this study, we investigated the role of lncRNA-MEG3 in diabetes-related microvascular dysfunction. We show that MEG3 expression level is significantly down-regulated in the retinas of STZ-induced diabetic mice, and endothelial cells upon high glucose and oxidative stress. MEG3 knockdown aggravates retinal vessel dysfunction in vivo, as shown by serious capillary degeneration, and increased microvascular leakage and inflammation...

Bile acid (BA) metabolism is tightly controlled by nuclear receptor signaling to coordinate regulation of BA synthetic enzymes and transporters. Here we reveal a molecular cascade consisting of the antiapoptotic protein BCL2, nuclear receptor Shp, and long non-coding RNA (lncRNA) H19 to maintain BA homeostasis. Bcl2 was overexpressed in liver of C57BL/6J mice using adenovirus mediated gene delivery for two weeks. Hepatic overexpression of Bcl2 caused drastic accumulation of serum BA and bilirubin levels and dysregulated BA synthetic enzymes and transporters...

BACKGROUND & AIMS: Emerging evidence has demonstrated the aberrant expression of long non-coding RNAs (lncRNAs) in various malignancies including HCC. However, the knowledge of cancer stem cell-related lncRNAs remains limited. METHODS: lnc-DILC (lncRNA downregulated in liver cancer stem cells (LCSCs)) was identified by microarray and validated by real-time PCR. The role of lnc-DILC in LCSCs was assessed both in vitro and in vivo. Pull down assay and oligoribonucleotides or oligodeoxynucleotides treatment were conducted to evaluate the interaction between lnc-DILC and interleukin-6 (IL-6) promoter...

Kawasaki disease (KD) is an autoimmune disease in which the medium-sized blood vessels throughout the body become inflamed. The increased evidences showed that TNF-α was association with vascular inflammation in KD patients. However the detailed mechanism was still unclear. Recent studies indicated abnormal expressed long non-coding RNAs (LncRNAs) involved in many diseases. Thus the purpose of this study is to explore the role of lncRNAs in KD and find out the new target for KD treatment. In this study, firstly we verified the overexpressed TNF-α in KD patients, and found TNF-α was able to induce HUVECs apoptosis and inhibit HUVECs proliferation...

UNLABELLED: Hepatic injury provoked by cold storage is a major problem affecting liver transplantation, as exposure to cold induces apoptosis in hepatic tissues. Long noncoding RNAs (lncRNAs) are increasingly understood to regulate apoptosis, but the contribution of lncRNAs to cold-induced liver injury remains unknown. Using RNA-seq, we determined the differential lncRNA expression profile in mouse livers after cold storage and found that expression of the lncRNA TUG1 was significantly down-regulated...

BACKGROUND: Although Helicobacter pylori (H.pylori) is the dominant gastrointestinal pathogen, the genetic and molecular mechanisms underlying H.pylori-related diseases have not been fully elucidated. Long non-coding RNAs (lncRNAs) have been identified in eukaryotic cells, many of which play important roles in regulating biological processes and pathogenesis. However, the expression changes of lncRNAs in human infected by H.pylori have been rarely reported. This study aimed to identify the dysregulated lncRNAs in human gastric epithelial cells and tissues infected with H...

BACKGROUND: Mammalian aging is a highly complex process, a full mechanistic understanding of which is still lacking. One way to help understand the molecular changes underlying aging is through a comprehensive analysis of the transcriptome, the primary determinant of age-related phenotypic diversity. Previous studies have relied on microarray analysis to examine gene expression profiles in different tissues of aging organisms. However, studies have shown microarray-based transcriptional profiling is less accurate and not fully capable of capturing certain intricacies of the global transcriptome...

Classically or alternatively activated macrophages (M1 and M2, respectively) play distinct and important roles for microbiocidal activity, regulation of inflammation and tissue homeostasis. Despite this, their transcriptional regulatory dynamics are poorly understood. Using promoter-level expression profiling by non-biased deepCAGE we have studied the transcriptional dynamics of classically and alternatively activated macrophages. Transcription factor (TF) binding motif activity analysis revealed four motifs, NFKB1_REL_RELA, IRF1,2, IRF7 and TBP that are commonly activated but have distinct activity dynamics in M1 and M2 activation...

MicroRNAs (miRNAs) are evolutionarily conserved and naturally abundant molecules of single-stranded, non-coding RNA from ∼17 to 25 nucleotides long. MiRNAs act at post-transcriptional level either to suppress gene translation or to induce mRNA degradation, according to the degree of complementarity with their target sequences. MiR-155 is a typical representative of the miRNA family that plays a crucial role in cell differentiation and organism development. A number of studies have shown that miR-155 can not only regulate cell proliferation, apoptosis and lymphoma progression, but also plays an important part in various other physiological and pathological processes...

A large part of the human genome is transcribed in non-coding RNAs, transcripts that do not code for protein, including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs). MiRNAs are short single-stranded RNA molecules that negatively regulate gene expression at the post-transcriptional level. They play an important regulatory role in many biological processes. Consequently, altered expression of these non-coding RNAs has been shown to lead to inflammation and disease. In contrast, lncRNAs, can both enhance or repress the expression of protein-coding genes...
