Hodgkin lymphoma (HL) is a malignancy of germinal center (GC) B-cell origin. To explore the role of long noncoding RNAs (lncRNAs) in HL, we studied LncRNA expression patterns in normal B-cell subsets, HL cell lines, and tissues. Naive and memory B cells showed a highly similar lncRNA expression pattern, distinct from GC-B cells. Significant differential expression between I-IL and normal GC-B cells was observed for 475 lncRNA loci. For two ...

In recent years, technological advances in transcriptome profiling revealed that the repertoire of human RNA molecules is more diverse and extended than originally thought. This diversity and complexity mainly derive from a large ensemble of noncoding RNAs. Because of their key roles in cellular processes important for normal development and physiology, disruption of noncoding RNA expression is intrinsically linked to human disease, including ...

With the consideration of the broad involvement of microRNAs (miRNAs) in the regulation of molecular networks in the brain, it is not surprising that miRNA dysregulation causes neurodegeneration in animal models. miRNA profiling in the human brain has revealed miR-132 as one of the most severely down-regulated miRNAs at the intermediate and late Braak stages of Alzheimer's disease (AD), as well as in other neurodegenerative disorders. ...

The biogenesis of ribosomes and their coordination of protein translation consume an enormous amount of cellular energy. As such, it has been established that the inhibition of either process can extend eukaryotic lifespan. Here, we used next-generation sequencing to compare ribosome-associated RNAs from normal strains of Caenorhabditis elegans to those carrying the life-extending daf-2 mutation. We found a long noncoding RNA (lncRNA), ...

© Springer Nature Singapore Pte Ltd. 2018. Recently large-scale genomic analyses have reported that the vast majority of somatic copy number alterations found in human cancers map to transcribed regions lacking protein-coding potential. This is not surprising considering that, although most of the human genome is transcribed into various classes of RNAs, less than 2% of them encodes for proteins. Among them, long noncoding RNAs (lncRNAs) ...

NEAT1 is one of the most studied lncRNAs, in part because its silencing in mice causes defects in mammary gland development and corpus luteum formation and protects them from skin cancer development. Moreover, depleting NEAT1 in established cancer cell lines reduces growth and sensitizes cells to DNA damaging agents. However, NEAT1 produces two isoforms and because the short isoform, NEAT1_1, completely overlaps the 5' part of the long NEAT1_2 ...

The lncRNA Neat1 is an essential architectural component of paraspeckle nuclear bodies. Although cell-based studies identified Neat1-paraspeckles as key regulators of gene expression through retention of hyperdited mRNAs and/or transcription factors, it is unclear under which specific physiological conditions paraspeckles are formed in vivo and whether they have any biological relevance. Herein, we show that paraspeckles are assembled in luminal ...
