Age related macular degeneration is one of the most common causes of vision loss in the elderly. Long noncoding RNAs (lncRNAs) serve important roles in regulating gene expression by acting as competing endogenous RNAs (ceRNAs). However, the roles of specific lncRNAs and their associated ceRNA function induced by clusterin in cultured retinal pigment epithelial (RPE) cells remain to be fully elucidated. Based on high throughput sequencing data from RPE cells treated with or without clusterin, the present study identified differentially expressed mRNAs, lncRNAs and microRNAs (miRNAs)...

In recent years, accumulating evidence indicates that long noncoding RNAs (lncRNAs) have emerged as powerful influence factors in the progression of multiple malignancies. Dysregulation of lncRNA HNF1A-antisense 1 (HNF1A-AS1) has been reported in many types of human cancers, and studies on HNF1A-AS1 function in cancers revealed that HNF1A-AS1could act as either oncogene or tumor suppressor. Nevertheless, the functional involvement of HNF1A-AS1 in colon cancer remains unknown. In this study, we reported that HNF1A-AS1 was frequently upregulated in colon cancer tissues and associated with poor prognosis...

We found that Gm15290 was one of the most upregulated lncRNAs in the adipose of ob/ob mice through lncRNA microarray analysis. Then, manipulations of overexpression and silencing in mouse primary adipocytes showed that Gm15290 positively regulated adipogenesis, manifested by increasing lipid deposition and upregulating adipogenic genes including PPARγ, C/EBPα, and aP2. However, overexpression of mutant Gm15290 (at the binding site of miR-27c) did not have an promoting effect on adipogenesis. Additionally, Gm15290 was found to potentially interact with miR-27b that had been identified as a PPARγ targeting miRNA, and we verified their interaction by luciferase activity and RNA pull down assays...

Anti-Müllerian hormone (AMH) is critical to the regression of Müllerian ducts during mammalian male differentiation and targets ovarian granulosa cells and testicular Sertoli and Leydig cells of adults. Specific effects of AMH are exerted via its receptor, AMH type II receptor (Amhr2), but the mechanism by which the Amhr2 gene is specifically activated is not fully understood. To see whether a proximal promoter was sufficient to Amhr2 gene activation, we generated transgenic mice that bore the enhanced green fluorescent protein (EGFP) gene driven by a 500-bp mouse Amhr2 gene promoter...

Enhancers are key cis-acting gene regulatory elements in eukaryotes, which can effectively promote the expression of target genes. Emerging evidence showed that enhancers in activation state could be transcribed to enhancer RNAs (eRNAs), the processes of which are regulated by various signaling systems and actions of signal-dependent transcription factors. Compared with the other transcripts (e.g. lncRNA, mRNA), eRNAs have shorter sequences, lower stability, and higher tissue specificity. eRNAs play roles in the initiation or stabilization of enhancer-promoter looping, and promote the expression of target genes...

In this study, we report that long non-coding RNA (lncRNA) SNHG16 is upregulated in non-small cell lung cancer (NSCLC) tissues, and is correlated with tumor size, TNM stage and lymph node metastasis. Kaplan-Meier analysis shows that the patients with high SNHG16 expression have poorer disease-free survival (DFS) and overall survival (OS) than the patients with low SNHG16 expression. Multivariate Cox regression analysis reveals that SNHG16 expression could be regarded as an independent predictor for DFS and OS in NSCLC patients...

BACKGROUND: The interleukin 28 receptor alpha (IL28RA) gene was indicated to be associated with apoptosis. However, it was not clear whether long non-coding RNA 260 (lncRNA 260)-specific siRNA targeting IL28RA gene could inhibit hypoxic reoxygenation (H/R) cardiomyocytes injury or not. To explore the mechanisms underlying the protective effects of lncRNA260-specific siRNA-mediated inhibition of IL28RA from H/R injury in cardiomyocytes, the current research was performed. METHODS: The primary neonatal rat cardiomyocytes were transfected with three different pairs of siRNA specific to lncRNA260 targeting IL28RA gene and then were undergone with the conditions simulating H/R injury...
