The oocyte-to-embryo transition (OET) transforms a differentiated gamete into pluripotent blastomeres. The accompanying maternal-zygotic RNA exchange involves remodeling of the long non-coding RNA (lncRNA) pool. Here, we used next generation sequencing and de novo transcript assembly to define the core population of 1,600 lncRNAs expressed during the OET (lncRNAs). Relative to mRNAs, OET lncRNAs were less expressed and had shorter transcripts, mainly due to fewer exons and shorter 5' terminal exons. Approximately half of OET lncRNA promoters originated in retrotransposons suggesting their recent emergence...

The majority of patients with epithelial ovarian cancer are diagnosed at a late stage when peritoneal metastases exist, however, there is little knowledge of the metastatic process in this disease setting. In this study, we report the identification of the long non-coding RNA LINC00092 as a nodal driver of metastatic progression mediated by cancer-associated fibroblasts (CAF). Pro-metastatic properties of CAF in vitro and in vivo were found to associate with elevated expression of the chemokine CXCL14. In clinical specimens, elevated levels of CXCL14 in CAF also correlated with poor prognosis...

Survival of patients with glioma remains poor, which is largely attributed to active carcinogenesis. Accumulating evidence indicates that long non-coding RNAs (lncRNAs) play key roles in tumor initiation and progression. However, the function of lncRNA ZFAS1 in glioma is still unclear. In the current study, we found that ZFAS1 was upregulated in glioma tissues and cell lines. High ZFAS1 expression in glioma tissues was significantly correlated with advanced tumor stage and poor overall survival. Furthermore, in vitro assays demonstrated that ZFAS1 inhibition significantly suppressed glioma cell proliferation, migration and invasion...

We aimed to explore the cellular action of micro-RNAs that are non-coding-RNAs modulating gene expression, whose expression is dysregulated in myotonic dystrophy (DM1). Basic procedure was to measure the levels of muscle-specific myo-miRNAs (miR-1, miR-133a/b, miR-206) in muscle of 12 DM1 patients. Muscle fiber morphometry and a new grading of histopathological severity score were used to compare specific myo-miRNA level and fiber atrophy. We found that the levels of miR-1 and miR-133a/b were significantly decreased, while miR-206 was significantly increased as compared to controls...

Lung cancer is the most common human cancer, and the majority of lung cancer cases are categorized as non-small cell lung cancer (NSCLC). Long non-coding RNAs (lncRNAs) play key roles in the development and progression of human cancers. LncRNA breast cancer anti-estrogen resistance 4 (BCAR4) has been identified as an oncogenic lncRNA involved in the progression of breast cancer and osteosarcoma. However, the clinical significance of the lncRNA BCAR4 in NSCLC remains largely unclear. In the present study, real-time quantitative reverse transcriptase-polymerase chain reaction was used to examine the relative level of lncRNA BCAR4 in 68 cases of NSCLC tissues and their adjacent non-tumor tissues...

Long non-coding RNA LINC00152 had been reported as an oncogene in gastric and hepatocellular cancer. In this study, we show that LINC00152 is overexpressed in gallbladder cancer (GBC) tissue samples and cell lines. The high LINC00152 levels correlated negatively with the overall survival time in GBC patients. Functionally, LINC00152 dramatically promoted cell migration, invasion and epithelial-mesenchymal transition (EMT) progression in vitro. In vivo, LINC00152 overexpression significantly promoted tumour peritoneal spreading and metastasis...

Keratoconus (KTCN, OMIM 148300) is a degenerative eye disorder characterized by progressive stromal thinning that leads to a conical shape of the cornea, resulting in optical aberrations and even loss of visual function. The biochemical background of the disease is poorly understood, which motivated us to perform RNA-Seq experiment, aimed at better characterizing the KTCN transcriptome and identification of long non-coding RNAs (lncRNAs) that might be involved in KTCN etiology. The in silico functional studies based on predicted lncRNA:RNA base-pairings led us to recognition of a number of lncRNAs possibly regulating genes with known or plausible links to KTCN...

Exploring the biological functions of long non-coding RNAs (lncRNAs) has come to the foreground in recent years. Studies have indicated that the lncRNA metastasis‑associated lung adenocarcinoma transcript 1 (MALAT1) not only regulates tumorigenesis in hepatocellular carcinoma, but also controls cell cycle progression in hematopoietic cells. The present study was designed to investigate the biological role of lncRNA MALAT1 in liver regeneration. We carried out a series of assays during liver regeneration following 2/3 partial hepatectomy in mice...

BACKGROUND: Hepatocellular carcinoma (HCC) is third leading cause of cancer-related death globally. Evidence suggest that long non-coding RNAs (lncRNAs) have emerged as key regulators of tumorigenesis and metastasis in HCC. In this study, we investigated the functional significance of SNHG12 and explored whether SNHG12 can directly interact with miR-199a/b-5p in the progression of HCC. METHODS: We determined the expression level of SNHG12 in HCC tissues with quantitative real-time PCR and then studied its clinical significance...

: 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...

A major reason for oxaliplatin chemoresistance in colorectal cancer (CRC) is the acquisition of epithelial-mesenchymal transition (EMT) in cancer cells. The long non-coding RNA, MALAT1, is a highly conserved nuclear ncRNA and a key regulator of metastasis development in several cancers. However, its role in oxaliplatin-induced metastasis and chemo-resistance is not well known. In this study, we aim to investigate the prognostic and therapeutic role of MALAT1 in CRC patients receiving oxaliplatin-based therapy, and further explore the potential transcriptional regulation through interaction with EZH2 based on the established HT29 oxaliplatin-resistant cells...

HOTAIR is a long non-coding RNA highly expressed in cancer tissues and is a negative prognostic factor, whereas the mechanism by which HOTAIR expression is upregulated in cancers remains elusive. In the present study, the regulation of HOTAIR transcription was investigated in breast cancer cells MCF7 and T47D. We found that, when the RhoC-ROCK signaling was disturbed by specific siRNAs or chemical inhibitors, the expression of HOTAIR would be down-regulated. Further, MRTF-A and SRF were found to affect HOTAIR expression...

Hypertrophic scarring (HS), a fibroproliferative disorder caused by abnormal wound healing after skin injury, is characterized by excessive deposition of extracellular matrix and invasive growth of fibroblasts. Numerous studies have reported that non-coding RNAs (ncRNAs) including microRNAs (miRNAs, miRs) and long non-coding RNAs (lncRNAs) play important roles in HS formation. Exploring non-coding RNA-based methods to treat scar would be instrumental for devising new effective therapies against scar. This article is protected by copyright...

Post-transcriptional methylation of RNA cytosine residues to 5-methylcytosine (m5C) is an important modification with diverse roles, such as regulating stress responses, stem cell proliferation, and RNA metabolism. Here, we used RNA bisulfite sequencing (bsRNA-seq) for transcriptome-wide quantitative mapping of m5C in the model plant, Arabidopsis thaliana. We discovered more than a thousand m5C sites in Arabidopsis mRNAs, long non-coding RNAs, and other non-coding RNAs across three tissue types (siliques, seedling shoots, and roots) and validated a number of these sites...

Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is involved in the development and progression of many types of tumors. An aberrant expression of MALAT1 was observed in many kinds of cancers. However, the exact effects and molecular mechanisms of MALAT1 in human hilar cholangiocarcinoma (HCCA) progression are still unknown. Here, we investigated the role of MALAT1 in human HCCA cell lines and clinical tumor samples in order to determine the function of this lncRNA. In our research, lncRNA-MALAT1 was specifically upregulated in HCCA tissues and cell lines, and was associated with pathological T stage, a larger tumor size and perineural invasion...
