Identification of an lncRNA‑miRNA‑mRNA interaction mechanism in breast cancer

lncRNA

Non‑coding RNAs serve important roles in regulating the expression of certain genes and are involved in the principal biological processes of breast cancer. The majority of studies have focused on defining the regulatory functions of long non‑coding RNAs (lncRNAs) and microRNAs (miRNAs/miRs), and few studies have investigated how lncRNAs and miRNAs are transcriptionally regulated. In the present study, based on ...

Identification and characterization of a long non-coding RNA up-regulated during HIV-1 infection

lncRNA

Long non-coding RNAs (lncRNAs) are rapidly emerging as important regulators of a diverse array of cellular functions. Here, Columbia University researchers describe a meta-analysis of two independent RNA-seq studies to identify lncRNAs that are differentially expressed upon HIV-1 infection. Only three lncRNA genes exhibited altered expression of ≥ 2-fold in HIV-1-infected cells. Of these, the uncharacterized lncRNA LINC00173 was chosen ...

Two novel lncRNAs discovered in human mitochondrial DNA using PacBio full-length transcriptome data

lncrna

In this study, researchers at Nankai University introduced a general framework to use PacBio full-length transcriptome sequencing for the investigation of mitochondrial RNAs. As a result, they produced the first full-length human mitochondrial transcriptome based on the public PacBio data and characterized the human mitochondrial transcriptome with more comprehensive and accurate information. Other results included the determination of the H-strand ...

Plasma lncRNA HOTAIR could serve as a promising biomarker for diagnosing and monitoring NSCLC

lncrna

Long noncoding RNA (LncRNA) homeotic genes (HOX) transcript antisense RNA (HOTAIR) has been reported to play a vital role in various cancers. It has been found that HOTAIR was upregulated in non-small cell lung cancer (NSCLC) and involved in cell invasion and metastasis. The aberrant expression of HOTAIR is expected to serve as a potential biomarker for patients with NSCLC. ...

On the Origin of lncRNAs

lncRNA

Non-coding (nc)RNAs known as enhancer-derived RNAs (eRNAs) and as long ncRNAs (lncRNAs) have received much attention, but their true functional specialization and evolutionary origins remain obscure. The recent characterization of Bloodlinc, an eRNA derived from a super-enhancer that also functions as a lncRNA, suggests that lncRNAs can evolve from eRNAs.  Evolution of Long Non-Coding (lnc)RNAs (A) Typical enhancers are transcribed ...

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 of four prognostic lncRNAs for survival prediction of patients with hepatocellular carcinoma

lncRNA

As the fifth most common cancer worldwide, Hepatocellular carcinoma (HCC) is also the third most common cause of cancer-related death in China. Several lncRNAs have been demonstrated to be associated with occurrence and prognosis of HCC. However, identification of prognostic lncRNA signature for HCC with expression profiling data has not been conducted yet. With the reuse of public available TCGA ...

Discovery of novel long non-coding RNAs induced by subgroup J avian leukosis virus

lncRNA

Avian leukosis virus subgroup J (ALV-J) is an avian oncogenic retrovirus that has led to severe economic losses in the poultry industry in China in recent decades. Here, using high throughput transcriptome sequencing of HD11 and CEF cells infected with ALV-J, researchers from Yangzhou University identified a set of 4804 novel long non-coding transcripts and numerous differentially expressed long non-coding ...

lncRNA TERRA RNA Antagonizes ATRX and Protects Telomeres

Through an integration of genomic and proteomic approaches to advance understanding of long noncoding RNAs, researchers from Harvard Medical School investigate the function of the telomeric transcript, TERRA. By identifying thousands of TERRA target sites in the mouse genome, they demonstrate that TERRA can bind both in cis to telomeres and in trans to genic targets. They then define a ...
