Long non-coding RNAs (lncRNAs) lncRNAs are considered as non-protein coding transcripts >200 nt in length. The first non-coding RNA ever identified was the alanine (Ala) transfer RNA (tRNA), purified from yeast, whose structure was published in 1965. The role of long non-coding RNAs (lncRNAs) in subjects with SS is unclear. RNA-Seq is a well-established technology extensively used for transcriptome profiling, allowing the analysis of coding and non-coding RNA molecules. Long non-coding RNAs (lncRNAs) are a large class of RNA molecules exceeding 200 nucleotides in length that do not encode proteins. Nucleic Acids Research, 41: e166. Institute of Biochemistry, Genetics and Microbiology, University of Regensburg, Regensburg, Germany. To infer functional regulation by known and newly characterized ncRNAs, we exploited pre-mRNA abundance estimates from total RNA sequencing, revealing 316 microRNAs and 3,310 long non-coding RNAs. These are >200 nucleotides in length and similar to mRNAs, they. Increasing evidence indicates that lncRNAs exert an irreplaceable role in tumor initiation, progression, as well as metastasis, and are novel molecular. Open Access — free for readers, with article. Advances in RNA-sequencing techniques have led to the discovery of thousands of non-coding transcripts with unknown function. 11, 1268–1271 (2009). The ENCODE project reveals human genome is actively transcribed; however, coding genes only account for only 1. LNCipedia is a public database for long non-coding RNA (lncRNA) sequence and annotation.
