Hepatocellular carcinoma (HCC) accounts for a large proportion of cancer-associated mortality worldwide. The functional impact of long noncoding RNAs (lncRNAs) in human cancer is not fully understood. Here, we identified a novel oncogenic lncRNA termed lncPARP1, which was significantly upregulated in HCC. Increase of lncPARP1 expression was associated with age, AFP levels, tumor size, recurrence, and poor prognosis of HCC patients. Loss-of-function approaches showed that knockdown of lncPARP1 inhibited proliferation, migration and invasion, while induced apoptosis in HCC cells...

Long noncoding RNAs (lncRNAs) have been associated with hepatocellular carcinoma (HCC), but the underlying molecular mechanisms of their specific association with hepatocarcinogenesis have not been fully explored. Methods: miR503HG was identified by microarray and validated by real-time PCR. Survival analysis was evaluated using the Kaplan-Meier method and assessed using the log-rank test. In vitro and in vivo assays were preformed to explore the biological effects of miR503HG in HCC cells. The interaction of miR503HG with HNRNPA2B1 was identified by RNA pull-down and RNA immunoprecipitation...

Emerging studies have indicated the essential functions of long noncoding RNAs (lncRNAs) during cancer progression. However, whether lncRNAs contribute to the upregulation of v-ets erythroblastosis virus E26 oncogene homolog 1 (Ets-1), an established oncogenic protein facilitating tumor invasion and metastasis, in gastric cancer remains elusive. Herein, we identified Ets-1 promoter-associated noncoding RNA (pancEts-1) as a novel lncRNA associated with the gastric cancer progression via mining of publicly available datasets and rapid amplification of cDNA ends...

Accumulating evidence has indicated that long non-coding RNAs (lncRNAs) are critically involved in tumor progression. In current study, we reported a novel lncRNA signature correlated with bladder cancer development. Particularly, the lncRNA long stress-induced noncoding transcript 5 (LSINCT5) is significantly upregulated in human bladder cancer cell lines and tumor specimens. Meanwhile, high LSINCT5 expression correlates with poor prognosis, enhances tumor sphere formation and invasion in vitro. In vivo xenograft tumor growth is also elevated by LSINCT5 overexpression...

In mammals, their proper development during the early cleavage stages strongly relies on the gene products newly transcribed by zygotic genome activation (ZGA). Long noncoding RNAs (lncRNAs) have been characterized as key regulators of the ZGA process in mice and human. However, the ZGA stage has not yet been identified and epigenetic regulations of the ZGA process remain largely unknown in goats. Here, we show that ZGA occurred at the 8-cell stage in goats. During ZGA, tri-methylation of H3K9 was dynamically changed but maintained strong staining in development arrested embryos...

The transcriptome encompasses a range of species including messenger RNA, and other noncoding RNA such as rRNA, tRNA, and short and long noncoding RNAs. Due to the huge role played by mRNA in development and disease, several methods have been developed to sequence and characterize mRNA, with RNA sequencing (RNA-Seq) emerging as the current method of choice particularly for large high-throughput studies. Short-read RNA-Seq which involves sequencing of short cDNA fragments and computationally assembling them to reconstruct the transcriptome, or aligning them to a reference is the most widely used approach...

Long noncoding RNAs (lncRNAs) are RNA transcripts that are at least 200 nucleotides long and lack coding potential, and they have been demonstrated to be involved in a wide range of biological processes. Many lncRNAs, especially those enriched in nucleus, have been found to regulate gene expression at transcriptional level. Regulation of gene transcription by lncRNAs are mainly mediated by transcriptional regulators (TRs) which interact with lncRNAs. LncRNAs can either enhance or suppress TR's activity, which depends on different mechanism and cellular context...

Long noncoding RNAs (lncRNAs) are emerging as an important controller affecting metabolic tissue development, signaling, and function. However, little is known about the function and profile of lncRNAs in osteoblastic differentiation in mice. Here, we analyzed the RNA-sequencing (RNA-Seq) datasets obtained for 18 days in two-day intervals from neonatal mouse calvarial pre-osteoblast-like cells. Over the course of osteoblast differentiation, 4058 mRNAs and 3948 lncRNAs were differentially expressed, and they were grouped into 12 clusters according to the expression pattern by fuzzy c-means clustering...

Long noncoding RNAs (lncRNAs) emerged as important regulatory component of mechanisms involved in gene expression, chromatin modification and epigenetic processes, but they are rarely annotated in the bovine genome. Our study monitored the jejunum transcriptome of German Holstein calves fed two different milk diets using transcriptome sequencing (RNA-seq). To identify potential lncRNAs within the pool of unknown transcripts, four bioinformatic lncRNA prediction tools were applied. The intersection of the alignment-free lncRNA prediction tools (CNCI, PLEK and FEELnc) predicted 1,812 lncRNA transcripts concordantly comprising a catalogue of 1,042 putative lncRNA loci expressed in the calves' intestinal mucosa...

We summarize current knowledge regarding regulatory functions of long noncoding RNAs (lncRNAs) in yeast, with emphasis on lncRNAs identified recently in yeast colonies and biofilms. Potential regulatory functions of these lncRNAs in differentiated cells of domesticated colonies adapted to plentiful conditions versus yeast colony biofilms are discussed. We show that specific cell types differ in their complements of lncRNA, that this complement changes over time in differentiating upper cells, and that these lncRNAs target diverse functional categories of genes in different cell subpopulations and specific colony types...

Long noncoding RNAs (lncRNA) have been implicated in cancer but most of them remain largely unstudied. Here, we identified a novel NSUN2 methylated lncRNA (NMR), which was significantly upregulated in esophageal squamous cell carcinoma (ESCC), functioned as a key regulator of ESCC tumor metastasis and drug resistance. Upregulation of NMR correlated with tumor metastasis and indicated poor overall survival in ESCC patients. Functionally, NMR could promote tumor cell migration and invasion, inhibit cisplatin-induced apoptosis and increase drug resistance in ESCC cells...

OBJECTIVE: Long noncoding RNAs (lncRNAs) play important roles in the pathogenesis of bladder cancer. A recent study reported that lncRNA HNF1A-AS1 (HNF1A-AS1) was upregulated in urothelial carcinoma of the bladder (UCB) and served as a tumor promoter. However, the clinical significance of HNF1A-AS1 in the prognosis of patients with UCB was poorly understood. This work was designed to investigate the relationship between HNF1A-AS1 expression level and the prognosis of UCB. PATIENTS AND METHODS: Relative expression levels of HNF1A-AS1 in UCB tissues were determined by qRT-PCR...

Malignant tumor cells have several unique characteristics, and their ability to undergo epithelial-mesenchymal transition (EMT) is a molecular gateway to invasive behavior. Rapid proliferation and increased invasiveness during EMT enhance aberrant glucose metabolism in tumor cells. Meanwhile, aerobic glycolysis provides energy, biosynthesis precursors, and an appropriate microenvironment to facilitate EMT. Reciprocal crosstalk between the processes synergistically contributes to malignant cancer behaviors, but the regulatory mechanisms underlying this interaction remain unclear...

Long noncoding RNAs (lncRNAs) play important roles in diverse developmental and pathological processes through chromatin reprogramming, cis regulation and posttranscriptional modification. They have been extensively studied in both vertebrates and invertebrates. However, the information of lncRNAs in urochordate is still lacking. In this study, we used the RNA-Seq data from three developmental stages (18, 21 and 42 hours post fertilization, hpf) of embryos and larvae in Ciona savignyi to identify candidate lncRNAs and analyze their expression profiles...

Long noncoding RNAs (lncRNAs) are proposed to play essential roles in regulating gene transcription. Moreover, a subset has been implicated in modulating the expression of the nearby loci. Here we systematically evaluated the relationship between lncRNAs and their neighboring genes based on transcriptome expression profiles from 4900 samples across 12 cancer types. Our findings reveal that lncRNAs, especially those of high syntenic conservation across species, are spatially correlated with transcription factors across the genome...
