MicroRNAs play a big part in gene regulation-and evolution
egulating when and where certain proteins are made is crucial to the normal functioning of living things. To make proteins, information from DNA is transcribed into RNA molecules and then translated into the amino acids building blocks of proteins.   view more (2005-06-24)

MicroRNAs as tumor suppressors
In the May 1st issue of G&D, Drs. Yong Sun Lee and Anindya Dutta (UVA) reveal that microRNAs can function as tumor suppressors in vitro.   view more (2007-04-16)

Unicellular microRNA discovery
In the May 15th 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... view more (2007-04-30)

Short RNAs show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years.   view more (2008-10-02)

Discovery suggests why stem cells run through stop signs
Everyone knows that stem cells are controversial. Many people know that stem cells can grow into virtually any cell type found in the body, from a red blood cell to a muscle cell to a brain cell. But no one really knows why stem cells continue to divide and renew themselves long after the point... view more (2005-06-13)

Study establishes new class of cancer-causing genes
Over the past few years, scientists have discovered that a new class of genetic regulators called "microRNAs" influences normal human growth and development. Now, researchers have found that microRNAs also play an important role in human cancer.   view more (2005-06-08)

Hebrew University study opening new route for combating viruses
A unique technique for analyzing the function of microRNAs developed by a Hebrew University of Jerusalem doctoral student has led to the discovery of a new mechanism by which viruses evade the human immune system.   view more (2008-06-25)

University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome.   view more (2006-11-14)

Micro-molecule plays big role in birth defects
University of Florida researchers have learned how to selectively shut down a flyweight-sized genetic molecule that packs a heavyweight punch, a discovery that may help doctors better understand cancer, birth defects and other health problems.   view more (2005-07-20)

Renegade RNA — Clues to cancer and normal growth
Researchers at Johns Hopkins have discovered that a tiny piece of genetic code apparently goes where no bit of it has gone before, and it gets there under its own internal code.   view more (2007-01-05)

MicroRNAs make for safer cancer treatments
Viruses -- long regarded solely as disease agents -- now are being used in therapies for cancer. Concerns over the safety of these so-called oncolytic viruses stem from their potential to damage healthy tissues.   view more (2008-10-27)

UC Davis researchers identify a cellular pathway that makes prostate cancer fatal
Expanding evidence that tiny strands of RNA - called microRNAs - play big roles in the progress of some cancers, UC Davis researchers have identified one that helps jump start prostate cancer cell growth midway through the disease process, eventually causing it to become fatal.   view more (2007-11-28)

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.   view more (2005-11-30)

Dartmouth researchers find the root of the evolutionary emergence of vertebrates
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.   view more (2008-02-12)

Killing the messenger RNA — But which one?
Tiny molecules called microRNAs, only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the... view more (2007-02-23)

MicroRNAs Can Be Tumor Suppressors
University of Virginia researchers have discovered that microRNAs, a form of genetic material, can function as tumor suppressors in laboratory studies.   view more (2007-04-26)

Massive microRNA scan uncovers leads to treating muscle degeneration
Researchers have discovered the first microRNAs - tiny bits of code that regulate gene activity - linked to each of 10 major degenerative muscular disorders, opening doors to new treatments and a better biological understanding of these debilitating, poorly understood, often untreatable diseases.   view more (2007-10-18)

Molecules might identify high-risk acute-leukemia patients
New research suggests that certain small molecules used by cells to control the proteins they make might also help doctors identify adult acute-leukemia patients who are likely to respond poorly to therapy.   view more (2008-01-16)

Brain tissue reveals possible genetic trigger for schizophrenia
A study led by scientists from the University of North Carolina at Chapel Hill may have identified a molecular mechanism involved in the development of schizophrenia.   view more (2007-03-29)

Scientists dig deeper into the genetics of schizophrenia by evaluating microRNAs
Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders.   view more (2008-05-12)

Evolving complexity out of 'junk DNA'
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts.   view more (2008-02-12)

Gladstone scientists identify role of tiny RNAs in controlling stem cell fate
Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) and the University of California, San Francisco have identified for the first time how tiny genetic factors called microRNAs may influence the differentiation of pluripotent embryonic stem (ES) cells into cardiac muscle.   view more (2008-03-06)

Master switches found for adult blood stem cells
Johns Hopkins Kimmel Cancer Center scientists have found a set of "master switches" that keep adult blood-forming stem cells in their primitive state.   view more (2007-02-12)

Biologists have discovered a molecular circuit breaker that controls a zebrafish's remarkable ability to regrow missing fins, according to a new study from Duke University Medical Center.   view more (2008-03-17)

Two suppressor molecules affect 70 genes in leukemia
By restoring two small molecules that are often lost in chronic leukemia, researchers were able to block tumor growth in an animal model.   view more (2008-04-25)
