The short ASCC3 RNA isoform functions as a long non-coding RNA

Researchers from the Francis Crick Institute analyzed the transcription-related DNA damage response on a genome-wide scale with great spatial and temporal resolution. Upon UV irradiation, a slowdown of transcript elongation and restriction of gene activity to the promoter-proximal ∼25 kb is observed. This is associated with a shift from expression of long mRNAs to shorter isoforms, incorporating alternative last exons ...

Three-lncRNA signature – a novel biomarker for the accurate prognosis prediction HNSCC

lncRNA

Long non-coding RNAs (lncRNAs) have important biological functions and can be used as prognostic biomarkers in cancer. To identify a lncRNA prognostic signature for head and neck squamous cell carcinoma (HNSCC). Researchers at the Shanghai Jiao Tong University School of Medicine analysed RNA-seq data derived from the TANRIC database to identify a lncRNA prognostic signature model using the orthogonal partial ...

LncRNAs and miRNAs – potential biomarkers and therapeutic targets for prostate cancer

Prostate cancer (PCa) is the second lethal disease for men in western countries. Although androgen receptor (AR) signaling has been widely investigated, noncoding RNAs (ncRNAs), deficient of open reading frame, have also received considerable attention. Growing studies showed that the aberrant ncRNAs expression contributed to cell proliferation, metastasis and drug resistance in PCa. Therefore, therapeutically targeting ncRNAs may synergize androgen ...

Visualizing the secondary and tertiary architectural domains of lncRNA RepA

lncRNA

Long noncoding RNAs (lncRNAs) are important for gene expression, but little is known about their structures. RepA is a 1.6-kb mouse lncRNA comprising the same sequence as the 5′ region of Xist, including A and F repeats. It has been proposed to facilitate the initiation and spread of X-chromosome inactivation, although its exact role is poorly understood. To gain insight ...

Logic programming to infer complex RNA expression patterns from RNA-seq data

lncRNA

To meet the increasing demand in the field, numerous long noncoding RNA (lncRNA) databases are available. Given many lncRNAs are specifically expressed in certain cell types and/or time-dependent manners, most lncRNA databases fall short of providing such profiles. Researchers at the University of Louisville have developed a strategy using logic programming to handle the complex organization of organs, their tissues ...

UCSF CRISPR Study Reveals Unexpected Roles of Long Non-Coding RNAs

lncRNA

High-Throughput Screening Platform Finds that Distinct Non-Coding RNAs are Essential to the Growth of Different Cancer Cell Types UC San Francisco researchers have taken a major step toward understanding the function of the tens of thousands of human genes that do not code for proteins, a phenomenon considered one of the key remaining mysteries of the human genome. New findings ...

Identification of a serum circulating lncRNA panel for the diagnosis and recurrence prediction of bladder cancer

Accumulating evidence indicates that long non-coding RNAs (lncRNAs) play important roles in tumorigenesis and progression. Researchers from Shandong University aimed to identify a panel of lncRNAs for the diagnosis and recurrence prediction in bladder cancer (BC). The expression of 13 candidate lncRNAs was investigated in 80 BC and matched adjacent normal tissues via quantitative real-time PCR. The differentially expressed lncRNAs ...

Long intergenic non-coding RNA expression signature in human breast cancer

lncrna

Breast cancer is a complex disease, characterized by gene deregulation. There is less systematic investigation of the capacity of long intergenic non-coding RNAs (lincRNAs) as biomarkers associated with breast cancer pathogenesis or several clinicopathological variables including receptor status and patient survival. Researchers at the Vanderbilt University Medical Center designed a two-stage study, including 1,000 breast tumor RNA-seq data from The ...

Structural and Functional Annotation of Long Noncoding RNAs

lncrna

Protein-coding RNAs represent only a small fraction of the transcriptional output in higher eukaryotes. The remaining RNA species encompass a broad range of molecular functions and regulatory roles, a consequence of the structural polyvalence of RNA polymers. Albeit several classes of small noncoding RNAs are relatively well characterized, the accessibility of affordable high-throughput sequencing is generating a wealth of novel, ...

Stellaris® RNA Fluorescence In Situ Hybridization for the Simultaneous Detection of Immature and Mature Long Noncoding RNAs in Adherent Cells

lncRNA

RNA fluorescence in situ hybridization (FISH), long an indispensable tool for the detection and localization of RNA, is becoming an increasingly important complement to other gene expression analysis methods. Especially important for long noncoding RNAs (lncRNAs), RNA FISH adds the ability to distinguish between primary and mature lncRNA transcripts and thus to segregate the site of synthesis from the site ...
