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)
MicroRNA tweaks protein that controls early heart development
Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle. view more (2005-06-13)
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)
RNA snippet suppresses spread of aggressive breast cancer
A low cellular level of a tiny fragment of RNA appears to increase the spread of breast cancer in mouse models of the disease, according to researchers at Whitehead Institute for Biomedical Research. view more (2009-06-16)
MicroRNA may have fail-safe role in limb development
A tiny strand of molecules plays a role in how our arms and legs develop and grow-a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University. view more (2005-12-02)
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 cellular machinery that uses that information to create... view more...

MicroRNA helps prevent tumors
A microRNA directly regulates a gene implicated in human cancers, researchers from Whitehead Institute and Massachusetts Institute of Technology report in the February 22nd online issue of Science. view more (2007-02-23)
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)
Researchers find snippet of RNA that helps make individuals remarkably alike
"No two people are alike." Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are. view more (2009-05-06)
Throwing the micro switch: MicroRNA may link smoking risk gene to neurobiology of addiction
During the past several years, significant progress has been made in identifying susceptibility genes for nicotine dependence through genetic linkage and association analyses. view more (2009-04-23)
MIT reports new twist in microRNA biology
MIT scientists have found a new way that DNA can carry out its work that is about as surprising as discovering that a mold used to cast a metal tool can also serve as a tool itself, with two complementary shapes each showing distinct functional roles. view more (2008-01-14)
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)
Study shows microRNA-based diagnostic identifies squamous lung cancer with 96 percent sensitivity
A new study shows for the first time that a microRNA-based diagnostic test can objectively identify squamous lung cancer with 96% sensitivity, according to Harvey Pass, M.D. of the NYU Cancer Institute at NYU Langone Medical Center, one of the authors of the study published on-line ahead of print in the Journal of Clinical Oncology. view more (2009-03-10)
Stanford scientist to discuss new approach to treating hepatitis C virus
Last year Peter Sarnow, PhD, professor of microbiology and immunology at the Stanford University School of Medicine, identified a previously unknown mechanism that the hepatitis C virus uses to replicate, yielding a promising new approach to combating the disease-causing virus. view more (2006-04-06)
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)
Minuscule molecules pack a powerful punch
A role for a microRNA in the immune system has been shown by study of one of the world's first microRNA knockout mouse, reported Friday 27 April in Science. view more (2007-04-27)
Pair of microRNA molecules controls major oncogene in most common leukemia
Researchers at Ohio State University have discovered that two microRNA (miRNA) molecules help control the oncogene responsible for a dangerous form of B-cell chronic lymphocytic leukemia (B-CLL), the most common human leukemia in the world. view more (2006-12-18)
Making sense of antisense microRNAs
Three independent papers in the January 1st issue of G&D report on the discovery of a bidirectionally transcribed microRNA (miRNA) locus in Drosophila. view more (2008-01-02)
Oregon researchers discover a mechanism leading to cleft palate
By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries. view more (2008-02-12)
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)
