Long noncoding RNAs (lncRNAs) have recently emerged as pivotal regulators in governing fundamental biological processes, as well as in tumorigenesis. The nuclear paraspeckle assembly transcript 1 (NEAT1) is one of the most highly regulated lncRNAs in recent genomic datasets, however, its biological role and regulatory mechanism in ovarian cancer (OC) development and progression are poorly defin...

Oxidized low-density lipoprotein (oxLDL) indu-ces macrophage inflammation and lipid uptake, and serves important roles in the development of atherosclerosis. The long non-coding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (neat1) has two isoforms; the longer isoform, neat1_2, mediates the formation of subnuclear structures called paraspeckles. Reverse transcription‑quantitative polym...

The transcription factor ΔNp63, a master regulator of epithelial biology, is involved in regulating stem cell function and maintaining the integrity stratified tissues such as epidermis. To this end, ΔNp63 acts transcriptional repressor or activator towards distinct subset protein-coding genes microRNAs. However, how whether regulates long non-coding RNA (lncRNAs) expression not known. Here, we...

Paraspeckles are subnuclear particles involved in the regulation of mRNA expression. They are formed by the association of DBHS family proteins and the NEAT1 long noncoding RNA. Here, we show that a recently identified structural motif, the charged single α-helix, is largely conserved in the DBHS family. Based on the available structural data and a previously suggested multimerization scheme of...

Paraspeckles are nuclear bodies form around the long non-coding RNA, Neat1, and RNA-binding proteins. While their role is not fully understood, they are believed to control gene expression at a post-transcriptional level by means of the nuclear retention of mRNA containing in their 3'-UTR inverted repeats of Alu sequences (IRAlu). In this study, we found that, in pituitary cells, all components...
