RNA-seq-based genome annotation and identification of long-noncoding RNAs in the winegrape Riesling

lncRNA

The technological advances of RNA-seq and de novo transcriptome assembly have enabled genome annotation and transcriptome profiling in highly heterozygous species such as grapevine (Vitis vinifera L.). This work is an attempt to utilize a de novo-assembled transcriptome of the V. vinifera cultivar ‘Riesling’ to improve annotation of the grapevine reference genome sequence. Here researchers from Missouri State University and the ...

Comprehensive discovery of non-coding RNAs in acute myeloid leukemia cell transcriptomes

lncRNA

To comprehensively detect diverse and novel RNA species, researchers from Washington University, St. Louis compared deep small RNA and RNA sequencing (RNA-seq) methods applied to a primary acute myeloid leukemia (AML) sample. They were able to discover previously unannotated small RNAs using deep sequencing of a library method employing broader insert size selection. The researchers analyzed the long non-coding RNA (lncRNA) ...

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 ...

In Silico identification and annotation of non-coding RNAs by RNA-seq and De Novo assembly of the transcriptome

The complexity of the tomato (Solanum lycopersicum) transcriptome has not yet been fully elucidated. To gain insights into the diversity and features of coding and non-coding RNA molecules of tomato fruits, researchers from the University of Naples Federico II generated strand-specific libraries from berries of two tomato cultivars grown in two open-field conditions with different soil type. Following high-throughput Illumina RNA-sequencing ...

Identification and comparison of long non-coding RNAs in the silk gland between the domestic and wild silkworms

lncRNA

Under long-term artificial selection, the domestic silkworm (Bombyx mori) has increased its silk yield tremendously in comparison with its wild progenitor, Bombyx mandarina. However, the molecular mechanism of silk yield increase is still unknown. Comparative analysis of long non-coding RNAs (lncRNAs) may provide some insights into understanding this phenotypic variation. In this study, using the RNA-seq data of silk gland ...

AnnoLnc – a web server for systematically annotating novel human lncRNAs

lncRNA

Long noncoding RNAs (lncRNAs) have been shown to play essential roles in almost every important biological process through multiple mechanisms. Although the repertoire of human lncRNAs has rapidly expanded, their biological function and regulation remain largely elusive, calling for a systematic and integrative annotation tool. Here researchers from Peking University present AnnoLnc, a one-stop portal for systematically annotating novel human ...

The emerging role of long non-coding RNAs in endometrial cancer

lncRNA

The human genome is pervasively transcribed and approximately 98% of the genome is non-coding. Long non-coding RNAs (lncRNAs) are a heterogeneous group of RNA transcripts that are >200 nucleotides in length with minimal to no protein-coding potential. Similar to proteins, lncRNAs have important biological functions in both normal cells and disease states including many types of cancer. This review summarizes ...
