Discovery suggests why stem cells run through stop signs
One of the mysteries of stem cells is why they continue to divide and renew themselves long after the point where other cells stop dividing. Now scientists at Northwestern University and the University of Washington have found that tiny bits of genetic material called microRNAs are necessary for stem cell division to take place, suggesting that microRNAs shut off the signals that stop cell division in most other cells.

(2007-05-16)

MicroRNAs in plants
Researchers at MIT and Rice University have discovered that microRNAs, an emerging class of non-protein gene regulators thus far only identified in animals, also exist in plants.

Study finds more than one-third of human genome regulated by RNA
DNA and proteins have been viewed as the movers and shakers in genomic studies, with RNA seen as just a messenger shuttling information between the two. But researchers have discovered that small RNA molecules regulate more than one third of the genome. In other words, a molecule once relegated to the sidelines may be a principal player in regulating cellular mechanisms. (2005-01-14)

First extensive description of the human secreted miRNome
In an elaborate study, biologists of the University of Luxembourg have found out that small molecules named microRNAs are, against many hopes, not yet suitable for early diagnosis of skin cancer, and supposedly for other types of cancer, in blood samples. For the first time they analyzed all microRNAs in the serum of healthy people and thus provided a first complete image of the human 'miRNome' in blood samples, in reference to the better-known 'genome.'

Size doesn't matter
The beauty of fruit flies as a scientific model system is that they are easy to manipulate and they give results fast. New research from Ulrike Gaul, Ph.D., at Rockefeller University, takes advantage of these characteristics to show that microRNAs are powerful regulators of fundamental processes including cell survival and nerve and muscle development. Certain microRNAs are conserved between flies and humans, so that these findings may shed light on how different human genes are controlled. (2005-07-01)

New insight into microRNA function can give gene therapy a boost
Scientists at the University of Eastern Finland and the University of Oxford have shown that small RNA molecules occurring naturally in cells, i.e. microRNAs, are also abundant in cell nuclei. Previously, microRNAs were mainly thought to be found in cytoplasm. The scientists also discovered that microRNA concentrations in cell nuclei change as a result of hypoxia. The findings strongly suggest that microRNAs play a role in the expression of genes in the cell nucleus. (2019-07-17)

NYU, Rockefeller researchers find complexity of regulation by microRNA genes
Collaborating researchers at New York University and Rockefeller University have discovered that microRNA genes, which have recently been shown to have key roles in gene regulation, can team up and regulate target genes in mammals. The paper, published in the latest issue of the journal Nature Genetics, found that a microRNA gene regulates, on average, 200 different human gene transcripts and that many microRNAs can coordinate their activities to regulate specific target genes.

Fingerprint of sleep habits as warning sign for heart disease
Chronic short sleep is associated with increased risk of clogged arteries, heart disease, and thus increased morbidity and mortality.

Short RNAs show a long history
Findings: MicroRNAs and piRNAs, two classes of small RNAs that regulate genes, have been discovered within diverse animal lineages, implying that they have been present since the ancestor of all animals (about a billion years ago). The early origins of microRNAs and piRNAs suggests that they have been shaping gene expression throughout the evolution of animals, contributing to the emergence of new species and perhaps even the emergence of multicellular animal life. (2008-10-01)

Advantage flu virus
Northwestern University scientists have discovered one of the ways the influenza virus disarms our natural defense system. The virus decreases the production of key immune regulating proteins in human cells that help fight the invader. The virus does this by turning on the microRNAs -- little snippets of RNA -- that regulate these proteins. The researchers are among the first to show the influenza virus can change the expression of microRNA to control immune responses in human lung cells. (2012-08-23)

MicroRNAs have shaped the evolution of the majority of mammalian genes
RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated. (2005-11-29)

Unicellular microRNA discovery
In the May 15 issue of Genes & Development, an international collaboration of researchers, led by Dr. Yijun Qi (National Institute of Biological Sciences, China), report on their discovery of microRNAs in the unicellular green alga, Chlamydomonas reinhardtii. This is the first finding of microRNAs in a unicellular organism. (2007-04-29)

Programmed cell death is an integral part of embryonic development. Exploring the regulation of the process, Ludwig-Maximilians-Universitaet in Munich researchers have shown that so-called microRNAs protect the precursors of neurons from 'precocious' elimination. (2017-02-10)

Once given 'no respect,' cells' tiny RNAS take driver's seat
Ribonucleic acid, or RNA, has long been thought to be important only to translate a gene's DNA into the proteins that are cells' workhorses. But new evidence shows that tiny bits of RNA not used to make proteins actually play central roles in normal biology and in the development of cancers. (2005-06-08)

Study shows marijuana's potential for treating autoimmune disorders
A new study from researchers at the University of South Carolina provides evidence that THC (tetrahydrocannabinol), a principal ingredient in marijuana, may be beneficial in treating those with autoimmune disorders. The study is the first to explore how tiny, yet powerful molecules called microRNAs are influenced by THC. The ability to alter microRNA expression could hold the key to successful treatments for a whole host of autoimmune diseases, including arthritis and multiple sclerosis. (2013-11-25)

Dartmouth College researchers and colleagues from the University of Bristol in the U.K. have traced the beginnings of complex life, i.e. vertebrates, to microRNA. The researchers argue that the evolution of microRNAs, which regulate gene expression, are behind the origin of early vertebrates. (2008-02-11)

MicroRNAs in the songbird brain respond to new songs
Whenever it hears an unfamiliar song from a male of the same species, a zebra finch stops chirping, hopping and grooming. Once it becomes familiar with the song, it goes back to its busy routine. In a new study, researchers found that levels of microRNAs -- short lengths of ribonucleic acid - go up or down in the songbird brain after it hears a new song. These microRNAs likely represent a new class of regulatory agents that fine-tune the brain's response to social information. (2011-06-30)
