Current glioma therapies allow in situ delivery of cytotoxic drugs to the tumour; however, gliomas show early recurrence due to their highly proliferative character. Long non-coding (lnc)RNAs play critical roles in tumorigenesis by controlling cell proliferation and cycling. However, the mechanism of action of lncRNAs in glioma development remains unclear. Here, we report that the lncRNA PLAC2 induces cell cycle arrest by targeting ribosomal protein (RP)L36 in glioma. RPL36 promoted cell proliferation and G1/S cell cycle progression...

The immune system is composed of diverse cell types that coordinate responses to infection and maintain tissue homeostasis. In each of these cells, extracellular cues determine highly specific epigenetic landscapes and transcriptional profiles to promote immunity while maintaining homeostasis. New evidence indicates that long non-coding RNAs (lncRNAs) play crucial roles in epigenetic and transcriptional regulation in mammals. Thus, lncRNAs have emerged as key regulatory molecules of immune cell gene expression programs in response to microbial and tissue-derived cues...

Long noncoding RNAs (lncRNAs) have been shown to play critical roles in the biology of various cancers. However, their expression patterns and biological functions in human colorectal cancer (CRC) remain largely unknown. The aim of this study was to explore lncRNA profiles in CRC and investigate key lncRNAs involved in CRC tumorigenesis and progression. The microarray data of six CRC and matched non-cancerous tissues revealed distinct lncRNA profiles, including 899 upregulated and 1,646 downregulated lncRNAs (p < 0...

Long noncoding RNA (lncRNA) has been implicated in cancer, but little is known about the role of lncRNAs as regulators of tumor metastasis. In the present study, we demonstrate that lncRNA TRERNA1 acts like an enhancer of SNAI1 to promote cell invasion and migration and to contribute to metastasis of gastric cancer (GC). TRERNA1 is significantly unregulated in GCs and GC cell lines. Increased TRERNA1 is positively correlated with lymph node metastasis of GCs. RNA immunoprecipitation (RIP) and chromatin immunoprecipitation (ChIP) assays revealed that TRERNA1 functions as a scaffold to recruit EZH2 to epigenetically silence epithelial-mesenchymal transition marker CDH1 by H3K27me3 of its promoter region...

The abnormally expressed LncRNAs played irreplaceable roles in the prognosis of prostate cancer (PCa). Therefore, we conducted this systematic review and meta-analysis to summarize the association between the expression of LncRNAs, prognosis and clinicopathology of PCa. 18 eligible studies were recruited into our analysis, including 18 on prognosis and 9 on clinicopathological features. Results indicated that aberrant expression of LncRNAs was significantly associated with biochemical recurrence-free survival (BCR-FS) (HR = 1...

Accumulating evidence suggested that long non-coding RNAs (lncRNAs) play essential roles in various biological processes, including tumorigenesis. Aberrant expression of LINC00161 has been reported in some cancer types, however, the association of LINC00161 and hepatocellular carcinoma (HCC) has not been evaluated. Here, we measured the expression of LINC00161 in HCC tissues and corresponding normal liver tissues using real-time PCR. The result showed that the expression level of LINC00161 was significantly higher in HCC tissues...

Postoperative cognitive dysfunction (POCD) is a common postoperative complication observed in elderly patients. Using microarray analyses, we comprehensively compared long non-coding RNA (lncRNA), messenger RNA (mRNA), and microRNA (miRNA) expression profiles in hippocampal tissues from a mouse model of POCD and control mice. A total of 175 lncRNAs, 117 mRNAs, and 26 miRNAs were differentially expressed between POCD and control mice. Gene ontology (GO) and KEGG pathway enrichment analyses were performed to explore the principal functions of dysregulated genes...

Pulmonary artery hypertension (PAH) is a rare and fatal disorder with extensive remodeling of pulmonary arteries mediated by hyperproliferation of pulmonary artery smooth muscle cell (PASMC). Aberrant platelet-derived growth factor (PDGF) activity can lead to hyperproliferation of PASMC, however, little is known about the role of long noncoding RNA (lncRNA) in this process. Using RNA sequencing (RNA-seq), we identified 725 lncRNAs in rat PASMC (RPASMC), 95 of which were expressed differentially in response to PDGF-BB treatment...

As non-coding RNAs, circular RNAs (cirRNAs) and long non-coding RNAs (lncRNAs) have attracted an increasing amount of attention. They have been confirmed to participate in many biological processes, including playing roles in transcriptional regulation, regulating protein-coding genes, and binding to RNA-associated proteins. Until now, the differences between these two types of non-coding RNAs have not been fully uncovered. It is still quite difficult to detect cirRNAs from other lncRNAs using simple techniques...

Renal fibrosis represents a final common outcome of many renal diseases and has attracted a great deal of attention. To better understand whether lncRNAs could be a player in this process or be a biomarker for renal fibrosis diagnosis, we compared transcriptome sequencing data on renal tissues and urine respectively between UUO (unilateral ureteral obstruction) and shamed (Sham) rat model. Numerous genes including lncRNAs with significant changes in their expression were identified. 24 lncRNAs were up-regulated and 79 lncRNAs were down-regulated in the renal tissues of the UUO rats...

It is becoming increasingly appreciated that the non-coding genome may have a great impact on the regulation of chromatin structure and gene expression. The innate immune response can be mediated upon lipopolysaccharide stimulation of macrophages which leads to immediate transcriptional activation of early responsive genes including tumor necrosis factor alpha (Tnfα). The functional role of non-coding RNAs, such as lncRNAs and microRNAs, on the transcriptional activation of proinflammatory genes and the subsequent regulation of the innate immune response is still lacking mechanistic insights...

Respiratory diseases hold several genome, epigenome, and transcriptional aberrations as a cause of the accumulated damage promoted by, among others, environmental risk factors. Such aberrations can also come about as an adaptive response when faced with therapeutic oncological drugs. In epigenetic terms, aberrations in DNA methylation patterns, histone code marks balance, and/or chromatin-remodeling complexes recruitment, among Polycomb Repressive Complex-2 (PRC2) versus Trithorax (TRX) Activator Complex, have been proposed to be affected by several previously characterized functional long non-coding RNAs (lncRNAs)...

Long noncoding RNAs (lncRNAs) have been reported to play diverse roles in biologic and pathologic processes, including myogenesis. We found that lncRNA AK017368 is highly expressed in skeletal muscle cells. Functional analyses showed that overexpression of AK017368 promoted proliferation and restrained differentiation of myoblasts; whereas inhibition of AK017368 had completely opposite effects in vitro In mice, knockdown of AK017368 promoted muscle hypertrophy in vivo RNA molecules of AK017368 acted mechanistically as competing endogenous RNAs to target micro-RNA (miR)-30c, which was supported by the results of bioinformatics analyses and dual-luciferase reporter assays...

Mesenchymal stem cell (MSC)‑based therapies have demonstrated efficacy in animal models of cardiovascular diseases. However, MSCs decrease in quantity and quality with age, which reduces their capacity for damage repair. Long noncoding (lnc) RNAs regulate gene transcription and the fate of post‑transcriptional mRNA, affecting a broad range of age‑associated physiological and pathological conditions, including cardiovascular disease and cancer cell senescence. However, the functional role of lncRNAs in stem cell senescence remains largely unknown...

It is widely reported that long non‑coding RNAs (lncRNAs) are involved in regulating cell differentiation, proliferation, apoptosis and other biological processes. Certain lncRNAs have been found to be crucial in various types of tumor. Taurine‑upregulated gene 1 (TUG1) has been shown to be expressed in a tissue‑specific pattern and exert oncogenic or tumor suppressive functions in different types of cancer in humans. According to previous studies, TUG1 is predominantly located in the nucleus and may regulate gene expression at the transcriptional level...

Long non‑coding RNAs (lncRNAs) serve a critical role in various biological processes including cell growth, transcriptional regulation and differentiation. Previous studies have demonstrated that human amnion‑derived mesenchymal stem cells (HAMSCs) possess the potential to promote proliferation and osteogenic differentiation of human bone marrow mesenchymal stem cells (HBMSCs). However, little is known about the roles of lncRNAs in these mechanisms. The present study investigated the expression of lncRNAs in HBMSCs co‑cultured with HAMSCs to study their involvement in the mechanism of osteogenic differentiation...

The immune system protects us from enormously diverse microbial pathogens but needs to be tightly regulated to avoid deleterious immune-mediated inflammation and tissue damage. A wide range of molecular determinants and cellular components work in concert to control the magnitude and duration of a given immune response. In the past decade, microRNAs (miRNAs), a major class of small non-coding RNA species, have been extensively studied as key molecular players in immune regulation. In this chapter, we will discuss how miRNAs function as negative regulators to restrict innate and adaptive immune responses...

Current studies indicate that long non-coding RNAs (lncRNAs) are frequently aberrantly expressed in cancers and implicated with prognosis in gastric cancer (GC). We intended to generate a multi-lncRNA signature to improve prognostic prediction of GC. By analyzing ten paired GC and adjacent normal mucosa tissues, 339 differentially expressed lncRNAs were identified as the candidate prognostic biomarkers in GC. Then we used LASSO Cox regression method to build a 12-lncRNA signature and validated it in another independent GEO dataset...

Despite increasing evidence to indicate that long non-coding RNAs (lncRNAs) are novel regulators of immunity, there has been no systematic attempt to identify and characterize the lncRNAs whose expression is changed following the induction of the innate immune response. To address this issue, we have employed next-generation sequencing data to determine the changes in the lncRNA profile in four human (monocytes, macrophages, epithelium, and chondrocytes) and four mouse cell types (RAW 264.7 macrophages, bone marrow-derived macrophages, peritoneal macrophages, and splenic dendritic cells) following exposure to the pro-inflammatory mediators, lipopolysaccharides (LPS), or interleukin-1β...
