The transcription factor c-Myc is an important regulator of cellular proliferation, differentiation and embryogenesis. While c-Myc can inhibit myoblast differentiation, the underlying mechanisms remain poorly understood. Here, we found that c-Myc does not only inhibits myoblast differentiation but also promotes myoblast proliferation and muscle fibre hypertrophy. By performing chromatin immunoprecipitation and high-throughput sequencing (ChIP-seq), we identified the genome-wide binding profile of c-Myc in skeletal muscle cells...

Large intergenic non-coding RNAs (lincRNAs) play widespread roles in epigenetic regulation during multiple differentiation processes, but little is known about their mode of action in cardiac differentiation. Here, we identified the key roles of a lincRNA, termed linc1405, in modulating the core network of cardiac differentiation by functionally interacting with Eomes. Chromatin- and RNA-immunoprecipitation assays showed that exon 2 of linc1405 physically mediates a complex consisting of Eomes, trithorax group (TrxG) subunit WDR5, and histone acetyltransferase GCN5 binding at the enhancer region of Mesp1 gene and activates its expression during cardiac mesoderm specification of embryonic stem cells...

Although long intergenic non-coding RNAs (lincRNA) role in various cancers is described, their significance in Multiple Myeloma (MM) remains poorly defined. Here we have studied the lincRNA profile and their clinical impact in MM. We performed RNA-seq on MM cells from 308 newly diagnosed and uniformly treated patients, 16 normal plasma cells and utilized RNA-seq data from 532 newly diagnosed patients from CoMMpass study to analyze for lincRNAs. We observed 869 differentially expressed lincRNAs in MM compared to normal plasma cells...

PURPOSE: An increasing number of long intergenic non-coding RNAs (lincRNAs) appear to play critical roles in cancer development and progression. To assess the association between SNPs that reside in regions of lincRNAs and breast cancer risk, we performed a large case-control study in China. METHODS: We carried out a two-stage case-control study including 2881 breast cancer cases and 3220 controls. In stage I, we genotyped 17 independent (r2  < 0.5) SNPs located in 6 tumor-related lincRNAs by using the TaqMan platform...

BACKGROUND: Long non-coding RNAs (lncRNAs) are involved in multiple biological processes in both mammals and plants. There is growing evidence that they are associated with development; but their expression and regulation during fruit ripening in the model plant tomato (Solanum lycopersicum) has yet to be described. RESULTS: Following integration of 134 RNA-seq data sets, we identified 79,322 putative lncRNAs, consisting of 70,635 lincRNAs, 8085 antisense non-coding RNAs (ancRNAs) and 602 sense lncRNAs (slncRNAs)...

Noncoding RNAs (ncRNAs) constitute the majority of the human transcribed genome. This largest class of RNA transcripts plays diverse roles in a multitude of cellular processes, and has been implicated in many pathological conditions, especially cancer. The different subclasses of ncRNAs include microRNAs, a class of short ncRNAs; and a variety of long ncRNAs (lncRNAs), such as lincRNAs, antisense RNAs, pseudogenes, and circular RNAs. Many studies have demonstrated the involvement of these ncRNAs in competitive regulatory interactions, known as competing endogenous RNA (ceRNA) networks, whereby lncRNAs can act as microRNA decoys to modulate gene expression...

Long intergenic noncoding RNAs (lincRNAs) have been gradually identified to be functional in a variety of different mechanisms associating with development and epigenetic regulation of cellular homeostasis. However, the study of lincRNAs in diabetic nephropathy (DN) is still in its infancy. Here, we have found dysexpressed long noncoding RNAs (lncRNAs) in renal tissues of db/db DN mice compared with db/m mice by RNA sequencing. In this study, 5 lincRNAs were confirmed to express in a consistent trend among these DN-related lncRNAs both in vivo and in vitro...

The spatiotemporal control of HOX gene expression is dependent on positional identity and often correlated to their genomic location within each loci. Maintenance of HOX expression patterns is under complex transcriptional and epigenetic regulation, which is not well understood. Here we demonstrate that HOTTIP, a lincRNA transcribed from the 5' edge of the HOXA locus, physically associates with the CCCTC-binding factor (CTCF) that serves as an insulator by organizing HOXA cluster into disjoint domains, to cooperatively maintain the chromatin modifications of HOXA genes and thus coordinate the transcriptional activation of distal HOXA genes in human foreskin fibroblasts...

Triple-negative breast cancer (TNBC) was associated with high rates of cancer recurrence and metastasis and currently no available molecularly target. Accumulating evidences have established the importance of lincRNA-ROR as a marker of cancers. In order to better understand the mechanism of lincRNA-ROR in TNBC, we provided a novel molecular target into the regulatory invasion and metastasis in present research. We found that lincRNA-ROR was upregulated in TNBC cell lines and tissue samples. The aberrant expression of lincRNA-ROR was shown to increase invasion and metastasis in MDA-MB-231 and loss of function by siRNA reverse these process...

Long non-coding RNAs (lncRNAs) have been implicated in numerous biological processes, including epigenetic regulation, cell-cycle control, and transcriptional/translational regulation of gene expression. Differential expression of lncRNAs and disruption of the regulatory processes are recognized as critical steps in cancer development. The role of lncRNAs in hepatitis B virus (HBV) infection is not well understood. Here we analyzed the expression of 135 lncRNAs in plasma samples of 82 HBV patients (classified as chronic patients, inactive carriers, or resolved patients) at diagnosis and at 12 months of treatment in relation to control group (81 healthy volunteers)...

FAM230C, a long intergenic non-coding RNA (lincRNA) gene in human chromosome 13 (chr13) is a member of lincRNA genes termed family with sequence similarity 230. An analysis using bioinformatics search tools and alignment programs was undertaken to determine properties of FAM230C and its related genes. Results reveal that the DNA translocation element, the Translocation Breakpoint Type A (TBTA) sequence, which consists of satellite DNA, Alu elements, and AT-rich sequences is embedded in the FAM230C gene. Eight lincRNA genes related to FAM230C also carry the TBTA sequences...

Inflammasome activation plays key roles in host defense, but also contributes to the pathogenesis of auto-inflammatory, and neurodegenerative diseases. As autophagy is connected with both the innate and adaptive immune systems, autophagic dysfunction is also closely related to inflammation, infection, and neurodegeneration. Here we identify that lincRNA-Cox2, previously known as a mediator of both the activation and repression of immune genes expression in innate immune cells, could bind NF-κB p65 and promote its nuclear translocation and transcription, modulating the expression of inflammasome sensor NLRP3 and adaptor ASC...

Diffuse large B-cell lymphoma (DLBCL) accounts for approximately 30% of the non-Hodgkin's lymphoma patients. The underlying molecular mechanism of its pathogenesis is not well defined and the survival rate of DLBCL patients is very low. Moreover, the annual incidence and mortality of DLBCL is still rising. Accordingly, identification and characterization of new molecular pathways of DLBCL will lead to the development of novel diagnostic markers and molecular therapeutic targets. Long non-coding RNAs (LncRNA) are non-coding RNAs with a length greater than 200 bp in eukaryotic cells, which can regulate the expression of their target genes at the transcriptional and post transcriptional levels...

Intramuscular fat (IMF) content is an important trait that can affect pork quality. Previous studies have identified many genes that can regulate IMF. Long intergenic non-coding RNAs (lincRNAs) are emerging as key regulators in various biological processes. However, lincRNAs related to IMF in pig are largely unknown, and the mechanisms by which they regulate IMF are yet to be elucidated. Here we reconstructed 105,687 transcripts and identified 1,032 lincRNAs in pig longissimus dorsi muscle (LDM) of four stages with different IMF contents based on published RNA-seq...

While gene expression dynamics have been extensively cataloged during hematopoietic differentiation in the adult, less is known about transcriptome diversity of human hematopoietic stem cells (HSCs) during development. To characterize transcriptional and post-transcriptional changes in HSCs during development, we leveraged high-throughput genomic approaches to profile miRNAs, lincRNAs, and mRNAs. Our findings indicate that HSCs manifest distinct alternative splicing patterns in key hematopoietic regulators...

Reprogramming energy metabolism is a hallmark of malignant tumors, including glioblastoma (GBM). Aerobic glycolysis is often utilized by tumor cells to maintain survival and proliferation. However, the underlying mechanisms of aerobic glycolysis in GBM remain elusive. Herein, we demonstrated that large intergenic non-coding RNA-RoR (LincRNA-RoR) functioned as a critical suppressor to inhibit the aerobic glycolysis and viability of GBM cells. We found that LincRNA-RoR was markedly reduced in GBM tissues compared with adjacent non-tumor tissues from 10 cases of GBM patients...
