A possible cause of Parkinson’s disease discovered

"Nucleolus", or small nucleus, is the term coined by early biologists for the tiny structure within the nucleus which they saw under the microscope. In this structure within the nucleus, RNA molecules and proteins are assembled to form ribosomes, th...

If junk DNA is useful, why is it not shared more...

The presence of introns in genes requires cells to process "messenger RNA" molecules before synthesizing proteins, a process that is costly and often error-prone. It was long believed that this was simply part of the price organisms paid for the fl...

In scientific first, researchers visualize naturally occurring mRNA

January 16, 2011 -- (BRONX, NY) -- In a technique that could eventually shed light on how gene expression influences human disease, scientists at Albert Einstein College of Medicine of Yeshiva University have for the first time ever successfully v...

CSHL study finds that 2 non-coding RNAs trigger formation of a...

Cold Spring Harbor, N.Y. -- The nucleus of a cell, which houses the cell's DNA, is also home to many structures that are not bound by a membrane but nevertheless exist as distinct compartments. A team of Cold Spring Harbor Laboratory (CSHL) scienti...

Tiny RNA molecules control labor, may be key to blocking premature...

DALLAS -- Nov. 15, 2010 -- Tiny molecules called microRNAs act together with hormones to control the onset of labor, raising the prospect that RNA-based drugs might be able to prevent premature labor, researchers at UT Southwestern Medical Center ...

Molecular fossil

In today's world of sophisticated organisms proteins are the stars. They are the indispensible catalytic workhorses, carrying out the processes essential to life. But long, long ago ribonucleic acid (RNA) reigned supreme. Now Northwestern Universi...

NYU Courant researchers develop algebraic model to monitor cellular change

Researchers at New York University's Courant Institute of Mathematical Sciences have developed a novel algebraic model of DNA "hybridization," a process central to most biotechnology devices that monitor changes in cell's gene expression or charact...

NC State develops more precise genetic ‘off switches’

Researchers at North Carolina State University have found a way to "cage" genetic off switches in such a way that they can be activated when exposed to UV light. Their technology gives scientists a more precise way to control and study gene function...

A new player in the innate immunity game?

Scientists have demonstrated for the first time that a certain class of RNA (known as long non-protein-coding RNA [lncRNA]) are involved in the host response to viral infection. These findings, published today in the online journal mBio®, could gr...

Penn study identifies molecular guardian of cell’s RNA

PHILADELPHIA - When most genes are transcribed, the nascent RNAs they produce are not quite ready to be translated into proteins - they have to be processed first. One of those processes is called splicing, a mechanism by which non-coding gene...
