Living in an RNA world

lncrna

The central dogma postulates that genes are first copied into messenger RNAs, which are then decoded into proteins with the help of transfer RNAs and ribosomal RNAs. It has long been known that there is more to the world of RNA...

MUSC researchers show how long non-coding RNA promotes tumor formation

A mechanism that pushes a certain gene to produce a non-coding form of RNA instead of its protein-coding alternative can promote the growth of cancer, report researchers at the Medical University of South Carolina (MUSC) in an article published online ahead of print on August 21, 2017 by Nature Cell Biology. The non-coding RNA soaks up a microRNA that prevents epithelial-to-mesenchymal ...

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 ...

Transcriptional and Post-transcriptional Gene Regulation by Long Non-coding RNA

lncRNA

Advances in genomics technology over recent years have led to the surprising discovery that the genome is far more pervasively transcribed than was previously appreciated. Much of the newly-discovered transcriptome appears to represent long non-coding RNA (lncRNA), a heterogeneous group of largely uncharacterised transcripts. Understanding the biological function of these molecules represents a major challenge and researchers from the University of ...

DES-ncRNA – A knowledgebase for exploring information about human micro and long noncoding RNAs based on literature-mining

lncRNA

Noncoding RNAs (ncRNAs), particularly microRNAs (miRNAs) and long ncRNAs (lncRNAs), are important players in diseases and emerge as novel drug targets. Thus, unraveling the relationships between ncRNAs and other biomedical entities in cells are critical for better understanding ncRNA roles that may eventually help develop their use in medicine. To support ncRNA research and facilitate retrieval of relevant information regarding ...

Impact of Dietary Interventions on Noncoding RNA Networks

lncRNA

Dietary interventions dramatically affect metabolic disease and lifespan in various aging models. Here, researchers from the Shanghai Institutes for Biological Sciences profiled liver microRNA (miRNA), coding, and long non-coding RNA (lncRNA) expression by high-throughput deep sequencing in mice across multiple energy intake and expenditure interventions. Strikingly, three dietary intervention network design patterns were uncovered: (1) lifespan-extending interventions largely repressed the ...

Long Non-coding RNAs in Gastric Cancer: A True Relationship or miR Chance?

Long non-coding RNAs (lncRNAs) are gradually drawing the attention of the cancer research community due to their pivotal involvement in tumorigenesis and tumor progression. These non-protein coding, >200 nucleotides long transcripts are aberrantly expressed in the majority of human malignancies, including gastric cancer (GC). The discovery that lncRNAs are severely deregulated across different human malignancies has prompted the pursuit of ...

Non-Coding RNAs – New Players in Skin Wound Healing

lncRNA

Significance: Wound healing is a basic physiological process that is utilized to keep the integrity of the skin. Impaired wound repair, such as chronic wounds and pathological scars, presents a major health and economic burden worldwide. To date, efficient targeted treatment for these wound disorders is still lacking, which is largely due to our limited understanding of the biological mechanisms ...

The Influence of microRNAs and Long Non-Coding RNAs in Cancer Chemoresistance

lncRNA

Innate and acquired chemoresistance exhibited by most tumours exposed to conventional chemotherapeutic agents account for the majority of relapse cases in cancer patients. Such chemoresistance phenotypes are of a multi-factorial nature from multiple key molecular players. The discovery of the RNA interference pathway in 1998 and the widespread gene regulatory influences exerted by microRNAs (miRNAs) and other non-coding RNAs have ...
