Long noncoding RNAs (lncRNAs) constitute a major class of the human transcriptome which play crucial roles in the key biological processes of both normal and malignant breast cells. Although the aberrant expression of lncRNAs has been well-documented in breast cancer (BC), little is currently known about the association between their expression levels in the breast tissue of healthy women and BC risk factors, especially the reproductive or demographic characteristics that are among the most well-known BC risk modifiers...

In order to study the role of long non-coding RNAs (lncRNAs) in predicting platinum-based chemoresistance in patients with high-grade serous ovarian carcinoma (HGS-OvCa), a=7-lncRNA signature was developed by analyzing 561 microarrays and 136 specimens from RNA-sequencing (RNA-seq) obtained from online databases [odds ratio (OR), 2.859; P<0.0001]. The upregulated lncRNAs (RP11-126K1.6, ZBED3-AS1, RP11-439E19.10 and RP11‑348N5.7) and downregulated lncRNAs [RNF144A-AS1, growth arrest specific 5 (GAS5) and F11-AS1] exhibited high sensitivity and specificity in predicting chemoresistance in the Gene Expression Omnibus and the Cancer Genome Atlas (area under curve >0...

Mesenchymal stem cells (MSCs) are important pluripotent stem cells and a major source of adipocytes in the body. However, the mechanism of adipogenic differentiation has not yet been completely elucidated. In this study, the long noncoding RNA GAS5 was found to be negatively correlated with MSC adipogenic differentiation. GAS5 overexpression negatively regulated adipocyte formation, whereas GAS5 knockdown had the opposite effect. Further mechanistic analyses using luciferase reporter assays revealed that GAS5 regulates the adipogenic differentiation of MSCs by acting as competing endogenous RNA (ceRNA) to sponge miR-18a, which promotes adipogenic differentiation...

The long non-coding RNA GAS5 has been reported as a tumor suppressor in many cancers. However, its functions and mechanisms remain largely unknown in esophageal squamous cell carcinoma (ESCC). In this study, we found that GAS5 was over-expressed in ESCC tissue compared with that in normal esophageal tissue in a public database. Functional studies showed that GAS5 could inhibit ESCC cell proliferation, migration and invasion in vitro. Further analysis revealed that GAS5 was regulated by interferon (IFN) responses via the JAK-STAT pathway...

One important feature of cerebral ischemia is hypoxia injury in nerve cells. Growth arrest-specific transcript 5 (GAS5) is widely reported as a tumor suppressor gene; however, the investigations about its role in cerebrovascular disease are relatively rare. This study was aimed to explore the impact of GAS5 on hypoxia response in nervous cells. PC-12 cells were incubated under anoxic condition to induce hypoxia injury. Regulatory effects of GAS5 on miR-124 and miR-124 on ICAM-1 expression were assessed by qRT-PCR and/or Western blot...

Porphyromonas gingivalis ( P. gingivalis ) is a major periodontal pathogen that can induce an immune response leading to a destructive inflammatory process. During the inflammatory process, interleukin-12 (IL-12) is secreted, correlating with bacterial clearance by macrophages. Bacterial sialidase has recently been shown to influence the synthesis and modification of the macromolecules on its surface, and is associated with the interaction between bacteria and host cells. We have previously constructed a P...

The human immunodeficiency virus (HIV) is the causative pathogen of acquired immunodeficiency syndrome (AIDS), which has generated worldwide concern. Long non-coding RNAs (lncRNAs) are a rising star in virus-host cross-talk pathways; they are differentially expressed during many viral infections and are involved in multiple biological processes. Currently, lncRNA growth arrest-specific transcript 5 (GAS5) is known to be down-regulated during HIV-1 infection. However, the functions and mechanisms of GAS5 in HIV-1 infection remain largely unknown...

BACKGROUND AND AIMS: Previous studies showed that down-regulation of GAS5 was involved in the development of gastric cancer (GC). However, the regulatory mechanism of down-expressed GAS5 in GC remains obscure. We aimed to investigate the role of rs145204276 of GAS5 in the development and metastasis process of GC. METHODS: 853 GC patients and 954 healthy controls were recruited. The variant rs145204276 was genotyped and the Chi2 test was used to compare the frequency of the genotype and the allele between the patients and the controls...

BACKGROUND: The regulatory role of long noncoding RNAs (lncRNAs) have been partially proved in embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). METHODS: In the current study, we investigated mouse ESC (mESC) self-renewal, differentiation, and proliferation in vitro by knocking down a lncRNA, growth arrest specific 5 (Gas5). A series of related indicators were examined by cell counting kit-8 (CCK-8) assay, quantitative reverse-transcription polymerase chain reaction (qRT-PCR), Western blot, alkaline phosphatase staining, propidium iodide (PI) staining, Annexin V staining, competition growth assay, immunofluorescence, and chromatin immunoprecipitation (ChIP)-qPCR...

BACKGROUND AND AIMS: Down-regulation of the growth arrest specific transcript 5 (GAS5) (long non-coding RNA) is associated with cell proliferation of gastric cancer (GC) and a poor prognosis. We aimed to investigate whether the variant rs145204276 of GAS5 is associated with the prognosis of GC in the Chinese population, and to unveil the regulatory mechanism underlying the GAS5 expression in GC tissues. METHOD: 1,253 GC patients and 1,354 healthy controls were included...

A growing body of evidence has shown bisphenol A (BPA), an estrogen-like industrial chemical, has adverse effects on the nervous system. In this study, we investigated the transcriptional behavior of long non-coding RNAs (lncRNAs) and mRNAs to provide the information to explore neurotoxic effects induced by BPA. By microarray expression profiling, we discovered 151 differentially expressed lncRNAs and 794 differentially expressed mRNAs in the BPA intervention group compared with the control group. Gene ontology analysis indicated the differentially expressed mRNAs were mainly involved in fundamental metabolic processes and physiological and pathological conditions, such as development, synaptic transmission, homeostasis, injury, and neuroinflammation responses...

Cell-free long non-coding RNAs (lncRNAs) are stably present in urine and can serve as non-invasive biomarkers for cancer. We aimed to identify signatures of lncRNAs in urine for diagnosis and prognosis of bladder cancer (BC). Screening of lncRNAs by microarray analysis was performed using urine samples of 10 BC patients and 10 controls. Expressions of candidate lncRNAs were evaluated in the training and validation set including 230 BC patients and 230 controls by quantitative reverse transcription polymerase chain reaction (qRT-PCR)...

BACKGROUND/AIMS: Osteoarthritis (OA) is the most frequently occurring joint disease and characterized by degeneration of cartilage. As the unique cell type in cartilage, chondrocytes play a crucial role during OA. Our study explored the influence of long non-coding RNA (lncRNA) growth arrest-specific transcript 5 (GAS5) on lipopolysaccharides (LPS)-induced injury in ATDC5 cells. METHODS: Cell viability, apoptosis and expression of inflammatory cytokines were all assessed to evaluate LPS-induce inflammatory injury...

Aberrant expression of long noncoding RNA GAS5 in bladder cancer (BC) cells was identified in recent studies. However, the regulatory functions and underlying molecular mechanisms of GAS5 in BC development remain unclear. Here, we confirmed that there was a negative correlation between GAS5 level and bladder tumor clinical stage. Functionally, overexpression of GAS5 reduced cell viability and induced cell apoptosis in T24 and EJ bladder cancer cells. Mechanistically, GAS5 effectively repressed EZH2 transcription by directly interacting with E2F4 and recruiting E2F4 to EZH2 promoter...
