MicroRNA News and Research

In genetics, microRNAs (miRNA) are single-stranded RNA molecules of 21-23 nucleotides in length, which regulate gene expression. miRNAs are encoded by genes from whose DNA they are transcribed but miRNAs are not translated into protein (i.e. they are non-coding RNAs); instead each primary transcript (a pri-miRNA) is processed into a short stem-loop structure called a pre-miRNA and finally into a functional miRNA. Mature miRNA molecules are partially complementary to one or more messenger RNA (mRNA) molecules, and their main function is to down-regulate gene expression.

Researchers identify microRNA-155 as prognostic marker, treatment target in patients with AML

A study has identified microRNA-155 as a new independent prognostic marker and treatment target in patients with acute myeloid leukemia that has normal-looking chromosomes under the microscope (that is, cytogenetically normal acute myeloid leukemia, or CN-AML).

Scientists identify new way to boost gene-silencing mechanism

A team led by scientists at The Scripps Research Institute (TSRI) has found how to boost or inhibit a gene-silencing mechanism that normally serves as a major controller of cells' activities. The discovery could lead to a powerful new class of drugs against viral infections, cancers and other diseases.

Researchers discover that microRNAs link two defining characteristics of fit muscles

Researchers discovered that small pieces of genetic material called microRNAs link the two defining characteristics of fit muscles: the ability to burn sugar and fat and the ability to switch between slow- and fast-twitch muscle fibers.

Study shows turning up few microRNAs may offer much anti-breast-cancer activity

A University of Colorado Cancer Center study recently published in the journal Cell Death & Disease shows that turning up a few microRNAs a little may offer as much anti-breast-cancer activity as turning up one microRNA a lot - and without the unwanted side effects.

Findings set the stage for identifying potential new drug targets, treatment strategies for AML

nvestigators for The Cancer Genome Atlas Research Network have detailed and broadly classified the genomic alterations that frequently underlie the development of acute myeloid leukemia, a deadly cancer of the blood and bone marrow.

Wistar researchers find surprising role for RNA-editing protein in gene silencing

RNA, once considered a bit player in the grand scheme by which genes encode protein, is increasingly seen to have a major role in human genetics.

Details about genomic landscapes of AML and endometrial cancer revealed

Two studies from The Cancer Genome Atlas program reveal details about the genomic landscapes of acute myeloid leukemia and endometrial cancer.

Neurons in the nose could be the key to early diagnosis of schizophrenia, says researcher

A debilitating mental illness, schizophrenia can be difficult to diagnose. Because physiological evidence confirming the disease can only be gathered from the brain during an autopsy, mental health professionals have had to rely on a battery of psychological evaluations to diagnose their patients.

Analysis identifies 37 RNA molecules that might predict survival in breast cancer patients

A Big Data analysis that integrates three large sets of genomic data available through The Cancer Genome Atlas has identified 37 RNA molecules that might predict survival in patients with the most common form of breast cancer.

Research on miRNAs offers new therapeutic potential to fight diseases

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes - from development to physiology to stress response.

Microglia guard nerve cells and play important role in their basic function

Researcher Johan Jakobsson and his colleagues have now published their results in Nature Communications.

Researchers decode toggle switch that can stimulate fat burning

For a long time, scientists have dreamt of converting undesirable white fat cells into brown fat cells and thus simply have excess pounds melt away. Researchers at the University of Bonn have now gotten a step closer to this goal: They decoded a "toggle switch" in mice which can significantly stimulate fat burning.

Experimental drug can reduce breast-cancer aggressiveness, restore drug-sensitivity

A new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) suggests that an unusual experimental drug can reduce breast-cancer aggressiveness, reverse resistance to the drug fulvestrant and perhaps improve the effectiveness of other breast-cancer drugs.

Santaris Pharma, Bristol-Myers Squibb partner to develop novel medicines using LNA Drug Platform

Santaris Pharma A/S, a privately held biopharmaceutical company focused on developing medicines targeted to disease-related mRNAs and microRNAs, today announced a worldwide strategic alliance with Bristol-Myers Squibb to discover and develop novel medicines using Santaris Pharma's proprietary Locked Nucleic Acid Drug Platform.

Study shows hsa-miR-146a overexpressed in most metastatic tumors

In order to kill, bladder cancer must metastasize, most commonly to the lung - what are the differences between bladder cancers that do and do not make this deadly transition? Research presented by the Director of the University of Colorado Cancer Center at the AACR Annual Meeting 2013 shows that one big difference is a little molecule known as hsa-miR-146a.

Study: microRNA is designed to stop proliferation of prostate cancer cells

The most recent in a series of studies from a team at the UC Davis Comprehensive Cancer Center has shown that a single molecule is at the heart of one of the most basic survival tactics of prostate cancer cells.

Immunotherapy and epigenetics advancements presented by Ludwig at the American Association for Cancer Research

A dozen Ludwig scientists from around the world presented the latest advancements in basic and clinical cancer research at this week’s American Association for Cancer Research (AACR) Annual Meeting 2013. Progress in immunotherapy and epigenetics led the program with important diagnostic and treatment implications for emerging cancer therapy.

Relationship between obesity and PCOS may be exaggerated, say researchers

The relationship between obesity and polycystic ovary syndrome may be exaggerated, likely because the women who actively seek care for the condition tend to be heavier than those identified through screening of the general population, researchers report.
