Recent advancements in cell-based therapies for the treatment of cardiovascular disease (CVD) show continuing promise for the use of transplanted stem and cardiac progenitor cells (CPCs) to promote cardiac restitution. However, a detailed understanding of the molecular mechanisms that control the development of these cells remains incomplete and is critical for optimizing their use in such therapy. Long non-coding (lnc) RNA has recently emerged as a crucial class of regulatory molecules involved in directing a variety of critical biological processes including development, homeostasis and disease...

Long non-coding RNA (lncRNA), transcripts of >200 bp in length that do not appear to exhibit any coding capacity, are important in the occurrence and development of cancer, cardiovascular and neurological diseases. However, effects of lncRNAs on photo‑aging remain to be elucidated. To explore the potential effects of the lncRNA metastasis‑associated lung adenocarcinoma transcript 1 (MALAT1) on photo‑aging in fibroblasts, MALAT1 expression was silenced in fibroblasts using small interference RNA. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) was used to examine MALAT1 expression in normal and silenced fibroblasts following irradiation with 60 mJ/cm2 ultraviolet B (UVB) and an ELISA assay was used to identify matrix metalloproteinase‑1 (MMP‑1) content in the cellular supernatant...

Long noncoding ribonucleic acids (lncRNAs) are an important category of noncoding RNAs that play crucial roles in controlling the expression of genes in health and in a range of illnesses including cardiovascular disease. A large body of genetic, experimental, and epidemiologic evidence suggests roles for an increasing number of lncRNAs in the regulation of metabolism, lipid profile, inflammation, and glucose metabolism in type II diabetes. Importantly, it has been suggested that lncRNAs can regulate chromatin alteration, messenger RNA stability, microRNA action, and can control transcription factors...

Cardiac remodeling occurs after stress to the heart, manifested as pathological processes, including hypertrophy and apoptosis of cardiomyocytes, dysfunction of vascular endothelial cells and vascular smooth muscle cells as well as differentiation and proliferation of fibroblasts, ultimately resulting in progression of cardiovascular diseases. Emerging evidence has revealed that long non-coding RNAs (lncRNAs) acted as powerful and dynamic modifiers of cardiac remodeling. LncRNAs including Chaer, Chast, Mhrt, CHRF, ROR, H19, and MIAT have been implicated in cardiac hypertrophy while NRF, H19, APF, CARL, UCA, Mhrt and several other lncRNAs (n379599, n379519, n384640, n380433 and n410105) in cardiomyocyte loss and extracellular matrix remodeling...

This review aimed to summarize the current research contents about long noncoding RNAs (lncRNAs) and some related lncRNAs as molecular biomarkers or therapy strategies in human cancer and cardiovascular diseases. Following the development of various kinds of sequencing technologies, lncRNAs have become one of the most unknown areas that need to be explored. First, the definition and classification of lncRNAs were constantly amended and supplemented because of their complexity and diversity. Second, several methods and strategies have been developed to study the characteristic of lncRNAs, including new species identifications, subcellular localization, gain or loss of function, molecular interaction, and bioinformatics analysis...

BACKGROUND: Long non-coding RNAs (lncRNA) regulate gene transcription and diverse cellular functions. We have recently reported a core inflammatory and metabolic ileal gene signature in treatment naïve pediatric Crohn Disease (CD), but the potential role of lncRNA was not known. We hypothesized that differences in ileal lncRNA would be associated with differences in protein-coding gene expression, suggesting a role for lncRNA in regulating those gene signatures. METHODS: Poly-A selected RNA-seq and Ensembl annotation were used to define differentially expressed ileal genes with false discovery rate correction of 0...

BACKGROUND: Endothelial cells have been shown to be in response to a variety of local and systemic stimuli, and are able to transition between quiescent and activated states. Endothelial cell activation is critical for the pathogenesis of various cardiovascular diseases. However, the expression changes of long non-coding RNAs (lncRNAs) are still unknown in the process of endothelial cell activation. Thus, this study was aimed to investigate expression changes of lncRNA before and after endothelial cell activation...

Long non-coding RNAs (lncRNAs) are over 200 nucleotides in length and are transcribed from the mammalian genome in a tissue-specific and developmentally regulated pattern. There is growing recognition that lncRNAs are novel biomarkers and/or key regulators of toxicological responses in humans and animal models. Lacking protein-coding capacity, the numerous types of lncRNAs possess a myriad of transcriptional regulatory functions that include cis and trans gene expression, transcription factor activity, chromatin remodeling, imprinting, and enhancer up-regulation...

The new millennium heralds an unanticipated surge of genomic information, most notably an expansive class of long noncoding RNAs (lncRNAs). These transcripts, which now outnumber all protein-coding genes, often exhibit the same characteristics as mRNAs (RNA polymerase II-dependent, 5' methyl-capped, multiexonic, polyadenylated); yet, they do not encode for stable, well-conserved proteins. Elucidating the function of all relevant lncRNAs in heart, vasculature, lung, and blood is essential for generating a complete interactome in these tissues...

Genetic discovery in blood pressure is generally referenced in relation to protein-coding genes, despite the fact that genes less than 2% of the genome. Recent exploration of the DNA sequences between genes, once called "junk" DNA, has revealed a wealth of transcripts for RNA species that do not encode protein. These non-coding RNAs (ncRNAs) have emerged as dynamic managers of the business of the genome, able to coordinate the expression of genes in time and space to achieve the complexities of normal development and growth...

Long non-coding RNAs (lncRNAs) have recently been shown as novel promising diagnostic or prognostic biomarkers for various cancers. However, lncRNA expression patterns and their predictive value in early diagnosis of myocardial infarction (MI) have not been systematically investigated. In our study, we performed a comprehensive analysis of lncRNA expression profiles in MI and found altered lncRNA expression pattern in MI compared to healthy samples. We then constructed a lncRNA-mRNA dysregulation network (DLMCEN) by integrating aberrant lncRNAs, mRNAs and their co-dysregulation relationships, and found that some of mRNAs were previously reported to be involved in cardiovascular disease, suggesting the functional roles of dysregulated lncRNAs in the pathogenesis of MI...

Long non-coding RNAs (lncRNAs) are an emerging class of transcripts that can modulate gene expression; however, their mechanisms of action remain poorly understood. Here, we experimentally determine the secondary structure of Braveheart (Bvht) using chemical probing methods and show that this ∼590 nt transcript has a modular fold. Using CRISPR/Cas9-mediated editing of mouse embryonic stem cells, we find that deletion of 11 nt in a 5' asymmetric G-rich internal loop (AGIL) of Bvht (bvht(dAGIL)) dramatically impairs cardiomyocyte differentiation...
