A stronger perturbation of lncRNAs expression may lead to the dysfunction of mitochondria in Down syndrome

lncrna

Trisomy 21 is the most common chromosomal disorder and underlies Down syndrome. Epigenetics, such as DNA methylation and post-translational histone modifications, plays a vital role in Down syndrome. However, the functions of epigenetics-related long noncoding RNAs (lncRNAs), found to have an impact on neural diseases such as Alzheimer’s disease, remain unknown in Down syndrome. In this study, researchers from Shanghai ...

Functional dissection of NEAT1 using genome editing

lncRNA

Large numbers of long noncoding RNAs have been discovered in recent years, but only a few have been characterized. NEAT1 (nuclear paraspeckle assembly transcript 1) is a mammalian long noncoding RNA that is important for the reproductive physiology of mice, cancer development, and the formation of subnuclear bodies termed paraspeckles. The two major isoforms of NEAT1 (3.7 kb NEAT1_1 and ...

Human Pancreatic β Cell lncRNAs Control Cell-Specific Regulatory Networks

lncRNA

Recent studies have uncovered thousands of long non-coding RNAs (lncRNAs) in human pancreatic β cells. β cell lncRNAs are often cell type specific and exhibit dynamic regulation during differentiation or upon changing glucose concentrations. Although these features hint at a role of lncRNAs in β cell gene regulation and diabetes, the function of β cell lncRNAs remains largely unknown. In ...

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 functions of long noncoding RNAs in development and stem cells

lncRNA

Eukaryotic genomes are pervasively transcribed, with tens of thousands of RNAs emanating from uni- and bi-directional promoters and from active enhancers. In vertebrates, thousands of loci in each species produce a class of transcripts called long noncoding RNAs (lncRNAs) that are typically expressed at low levels and do not appear to give rise to functional proteins. Substantial numbers of lncRNAs ...

Metastasis-associated long noncoding RNAs in gastrointestinal cancer: Implications for novel biomarkers and therapeutic targets

lncRNA

Long non-coding RNAs (lncRNAs), a newly discovered class of ncRNA molecules, have been widely accepted as crucial regulators of various diseases including cancer. Increasing numbers of studies have demonstrated that lncRNAs are involved in diverse physiological and pathophysiological processes, such as cell cycle progression, chromatin remodeling, gene transcription, and posttranscriptional processing. Aberrant expression of lncRNAs frequently occurs in gastrointestinal cancer ...

Linking Long Noncoding RNA Localization and Function

lncRNA

Recent studies have revealed the regulatory potential of many long noncoding RNAs (lncRNAs). Most lncRNAs, like mRNAs, are transcribed by RNA polymerase II and are capped, polyadenylated, and spliced. However, the subcellular fates of lncRNAs are distinct and the mechanisms of action are diverse. Investigating the mechanisms that determine the subcellular fate of lncRNAs has the potential to provide new ...
