Prostate cancer-associated lncRNAs

lncRNA

Long non-coding RNA (LncRNA) is defined as an RNA transcript that does not encode any protein, with a length longer than 200 nt. Based on the recent advances in high-throughput sequencing techniques, a large number of lncRNAs have been characterized as functional transcripts that play important roles in various biological processes as well as pathologic states. In a research field of ...

Identification of transposable elements contributing to tissue-specific expression of long non-coding RNAs

lncrna

It has been recently suggested that transposable elements (TEs) are re-used as functional elements of long non-coding RNAs (lncRNAs). This is supported by some examples such as the human endogenous retrovirus subfamily H (HERVH) elements contained within lncRNAs and expressed specifically in human embryonic stem cells (hESCs), as required to maintain hESC identity. There are at least two unanswered questions ...

lncRNA HANR promotes tumorigenesis and increase of chemoresistance

lncRNA

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third leading cause of cancer-related death. Critical roles for long non-coding RNAs (lncRNAs) have recently been demonstrated for a variety of cancers, including hepatocellular carcinoma. However, the effect and mechanism of lncRNAs in HCC tumorigenesis and chemoresistance have not been extensively characterized. In the current study, ...

Epidermal long non-coding RNAs are regulated by ultraviolet irradiation

lncRNA

Ultraviolet (UV) radiation causes the harmful effects on skin by the photochemical reaction and gene expression regulation. Recent evidences have shown that long non-coding RNAs (lncRNAs) play critical roles in a diverse range of biological functions. However, research on the effects of UV irradiation on lncRNA expression in epidermal cells is limited. The aim of this study was to identify ...

Gene regulation of mammalian long non-coding RNA

lncRNA

RNA polymerase II (Pol II) transcribes two classes of RNAs, protein-coding and non-protein-coding (ncRNA) genes. ncRNAs are also synthesized by RNA polymerases I and III (Pol I and III). In humans, the number of ncRNA genes exceeds more than twice that of protein-coding genes. However, the history of studying Pol II-synthesized ncRNA is relatively short. Since early 2000s, important biological ...

The Role of Long Non Coding RNAs in the Repair of DNA Double Strand Breaks

lncRNA

DNA double strand breaks (DSBs) are abrasions caused in both strands of the DNA duplex following exposure to both exogenous and endogenous conditions. Such abrasions have deleterious effect in cells leading to genome rearrangements and cell death. A number of repair systems including homologous recombination (HR) and non-homologous end-joining (NHEJ) have been evolved to minimize the fatal effects of these ...

New Reference Text Published – Long Non Coding RNA Biology

lncRNA

In recent years, our functional understanding of the genome has changed dramatically. The discovery of pervasive transcription and the prevalence of noncoding RNAs (ncRNAs) have challenged the traditional definition of genes and what should be considered a functional region of the genome. Noncoding RNAs are defined as transcripts that do not encode proteins. Formally, this classification includes components of the ...

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 ...

Targeting long non-coding RNA DANCR inhibits triple negative breast cancer progression

lncRNA

Triple negative breast cancer (TNBC) is non-responsive to conventional anti-hormonal and Her2 targeted therapies, making it necessary to identify new molecular targets for therapy. Long non-coding RNA anti-differentiation ncRNA (lncRNA DANCR) was identified in participating carcinogenesis of hepatocellular carcinoma, but its expression and potential role in TNBC progression is still unclear. In the present study, Researchers from Peking University Health Science ...
