OBJECTIVE(S): Long noncoding RNAs (lncRNAs)-activated by transforming growth factor beta (lncRNA-ATB) is known to be involved in the invasion of hepatocellular carcinoma by regulating target gene miR-200a. However, the role and molecular mechanisms of lncRNA-ATB/miR-200a in HCV-related liver fibrosis remains unclear. In this study, we examined the expression of lncRNA-ATB/miR-200a, and their target gene β-Catenin in liver tissues of HCV patients and hepatic stellate cells (HSCs) to elucidate the possible role of lncRNA-ATB/miR-200a axis in HSC activation and development of liver fibrosis...

The multi-drug resistance 2 knockout (Mdr2(-/-) ) mouse is a well-established model of cholestatic cholangiopathies. Female Mdr2(-/-) mice develop more severe hepatobiliary damage than male Mdr2(-/-) mice, which is correlated with a higher proportion of taurocholate (TCA) in bile. Although estrogen has been identified as an important player in intrahepatic cholestasis, the underlying molecular mechanisms of gender-based disparity of cholestatic injury remain unclear. The long non-coding RNA H19 is an imprinted, maternally expressed and estrogen-targeted gene, which is significantly induced in human fibrotic/cirrhotic liver and bile duct ligated mouse liver...

Multiple long non-coding RNAs (lncRNAs) have been demonstrated to be involved in liver disease. Increased cyclooxygenase-2 (COX‑2) levels have also been reported to be involved in the progression of liver cirrhosis. In the present study, the correlations between lncRNA‑COX‑2 RNA expression levels, COX‑2 mRNA expression levels and liver fibrosis were examined. Liver fibrosis was induced by intraperitoneal injection of carbon tetrachloride (CCl4) in mice for 2 months (CCl4‑2M) or 3 months (CCl4‑3M)...

A long non-coding RNA (lncRNA), named myocardial infarction associated transcript (MIAT), has been documented to confer risk of myocardial infarction (MI). The aim of this study is to elucidate the pathophysiological role of MIAT in regulation of cardiac fibrosis. In a mouse model of MI, we found that MIAT was remarkably up-regulated, which was accompanied by cardiac interstitial fibrosis. MIAT up-regulation in MI was accompanied by deregulation of some fibrosis-related regulators: down-regulation of miR-24 and up-regulation of Furin and TGF-β1...

Hepatocyte apoptosis in non-alcoholic steatohepatitis (NASH) can lead to fibrosis and cirrhosis, which permanently damage the liver. Understanding the regulation of hepatocyte apoptosis is therefore important to identify therapeutic targets that may prevent the progression of NASH to fibrosis. Recently, increasing evidence has shown that lncRNAs are involved in various biological processes and that their dysregulation underlies a number of complex human diseases. By performing gene expression profiling of 4,383 lncRNAs in 82 liver samples from individuals with NASH (n=48), simple steatosis but no NASH (n=11) and healthy controls (n=23), we discovered a liver-specific lncRNA (RP11-484N16...

Long non-coding RNAs (lncRNAs) are increasingly recognized as major players in regulating various biological processes. LncRNA HOX transcript antisense RNA (Hotair) has been extensively studied in cancer. However, the role of Hotair in liver fibrosis remains unknown. Here we observed that Hotair expression was significantly increased in CCl4-induced mouse liver fibrosis models, human fibrotic livers and activated hepatic stellate cells (HSCs) by TGF-β1 stimulation. Enforced expression of Hotair in LX-2 cells promoted cell proliferation and activation while inhibition of its expression had an opposite effect...

Long non-coding RNA (LncRNA)-activated by transforming growth factor-beta (LncRNA-ATB) is a key regulator of transforming growth factor-beta (TGF-β) signaling pathway, and is positively correlated with the development of liver cirrhosis and vascular invasion of hepatocellular carcinoma (HCC). However, the role of LncRNA-ATB in hepatitis C virus (HCV)-related liver fibrosis remains largely unknown. In the present study, we confirmed a high expression level of LncRNA-ATB in the liver tissues and plasma samples of patients with HCV-related hepatic fibrosis, and the plasma level of LncRNA-ATB was significantly correlated with liver fibrosis stages...

Cystic fibrosis (CF) is a life-shortening genetic disease. The root cause of CF is heritable recessive mutations that affect the cystic fibrosis transmembrance conductance regulator (CFTR) gene and the subsequent expression and activity of encoded ion channels at the cell surface. We show that CFTR is regulated transcriptionally by the actions of a novel long noncoding RNA (lncRNA), designated as BGas, that emanates from intron 11 of the CFTR gene and is expressed in the antisense orientation relative to the protein coding sense strand...

Although long non-coding RNAs (lncRNAs) are important players in the initiation and progression of many pathological processes, the role of lncRNAs in renal fibrosis still remains unclear. We showed that lncRNA-H19 expression was significantly up-regulated in TGF-β2-induced HK-2 cell fibrosis and unilateral ureteral obstruction (UUO)-induced renal fibrosis in vivo. H19 knockdown significantly attenuated renal fibrosis in vitro and in vivo. LncRNA-H19, miR-17, and fibronectin constituted to a regulatory network involved in renal fibrosis...

Methyl-CpG-binding protein 2 (MeCP2) plays a key role in liver fibrosis. However, the potential mechanism of MeCP2 in liver fibrosis remains unclear. Early reports suggest that LncRNA H19 is important epigenetic regulator with critical roles in cell proliferation, but its role in hepatic fibrosis remains elusive. Sprague-Dawley rats liver fibrosis was generated by 12-weeks treatment with CCl4 intraperitoneal injection. HSC-T6 cells were used in vitro study. The expression levels of MeCP2, H19, IGF1R, α-SMA, and Col1A1 were estimated by Western blotting, qRT-PCR and Immunohistochemistry...

Down-regulation of DUSP5 has been shown to increase cell proliferation. DUSP5 expression is regulated through epigenetic events involving LncRNA H19 human choriocarcinoma cell line. However, the molecular mechanisms of H19 modulating the DUSP5 expression in cardiac fibrosis remain largely unknown. Here, we identify H19 negatively regulation of DUSP5 gene expression in cardiac fibroblast and fibrosis tissues. In vivo, the expression levels of H19, DUSP5, α-SMA, p-ERK1/2, and ERK1/2 in cardiac fibrosis tissue were estimated by Western blotting, quantitative reverse transcription-polymerase chain reaction and immunohistochemistry...

Long non-coding RNAs constitute the most abundant part of the transcribed mammalian genome. lncRNAs affect all essential processes in the living cell including transcription, splicing, translation, replication, shaping of chromatin and post translational modification of proteins. Alterations in lncRNA expression have been linked to a number of diseases; thus, modulation of lncRNA expression holds a huge potential for gene-based therapy. In this review we summarize published data about lncRNAs in the context of hepatic carcinogenesis and liver fibrosis, and the corresponding potential targets for gene therapy...

Transcriptome analysis by RNA-seq technology allows novel insights into gene expression and regulatory networks in health and disease. To better understand the molecular basis of renal fibrosis, we performed RNA-seq analysis in the Unilateral Ureteric Obstruction (UUO) mouse model. We analysed sham operated, 2- and 8-day post-ligation renal tissues. Thousands of genes with statistical significant changes in their expression were identified and classified into cellular processes and molecular pathways. Many novel protein-coding genes were identified, including critical transcription factors with important regulatory roles in other tissues and diseases...
