Microarray expression profiling of long non-coding RNAs in epithelial ovarian cancer

lncRNA

Although numerous long non-coding RNAs (lncRNAs) have been identified to be important in human cancer, their potential regulatory roles in epithelial tumorigenesis and tumor progression in ovarian cancer remain unclear. Researchers from Nanjing Medical University set out to investigate lncRNAs that were differentially expressed (DE) in epithelial ovarian cancer and to explore their potential functions. The lncRNA profiles in five pairs ...

Identification and prioritization of long non-coding RNAs associated with autism

Genetic studies have identified many risk loci for autism spectrum disorder (ASD) although causal factors in the majority of cases are still unknown. Currently, known ASD risk genes are all protein-coding genes; however, the vast majority of transcripts in humans are non-coding RNAs (ncRNAs) which do not encode proteins. Recently, long non-coding RNAs (lncRNAs) were shown to be highly expressed ...

RNA-Seq analysis of lncRNAs

RNA-Seq is an approach to transcriptome profiling that uses deep-sequencing technologies to detect and accurately quantify RNA molecules originating from a genome at a given moment in time. In recent years, the advent of RNA-Seq has facilitated genome-wide expression profiling, including the identification of novel and rare transcripts like noncoding RNAs and novel alternative splicing isoforms. Advances in transcriptome reconstruction ...

A practical qPCR approach to detect TERRA, the elusive telomeric repeat-containing lncRNA

lncRNA

Telomeres, the heterochromatic structures that protect the ends of the chromosomes, are transcribed into a class of long non-coding RNAs, telomeric repeat-containing RNAs (TERRA), whose transcriptional regulation and functions are not well understood. The identification of TERRA adds a novel level of structural and functional complexity at telomeres, opening up a new field of research. TERRA molecules are expressed at ...

RACE-Seq – extension of human lncRNA transcripts by RACE coupled with long-read high-throughput sequencing

rna-seq

Long non-coding RNAs (lncRNAs) constitute a large, yet mostly uncharacterized fraction of the mammalian transcriptome. Such characterization requires a comprehensive, high-quality annotation of their gene structure and boundaries, which is currently lacking. Here researchers from the Barcelona Institute of Science and Technology describe RACE-Seq, an experimental workflow designed to address this based on RACE (rapid amplification of cDNA ends) and ...

Systematically profiling and annotating long intergenic non-coding RNAs

While more and more long intergenic non-coding RNAs (lincRNAs) were identified to take important roles in both maintaining pluripotency and regulating differentiation, how these lincRNAs may define and drive cell fate decisions on a global scale are still mostly elusive. Systematical profiling and comprehensive annotation of embryonic stem cells lincRNAs may not only bring a clearer big picture of these ...

Genome-wide profiling of long noncoding ribonucleic acid expression patterns by microarray

Ectopic and eutopic endometrial lncRNA and messenger RNA (mRNA) expression levels were determined by microarray in four patients; quantitative reverse transcription-polymerase chain reaction validation of 10 differentially expressed lncRNAs was conducted in another 21 patients. The lncRNAs’ functions were predicted through coexpressed mRNA annotations. A total of 948 lncRNA transcripts and 4,088 mRNA transcripts were dysregulated in ectopic endometrial tissue, ...
