Early-stage gene transcription creates access to DNA
A gene contained in laboratory yeast has helped an international team of researchers uncover new findings about the process by which protein molecules bind to control sequences in genes in order to initiate gene expression, according to findings reported in the journal Nature.   view more (2008-10-07)

Non-coding RNAs help silence the mammalian transcription
Dr. Shirley Tilghman and colleagues (Princeton University) lend new insight into the mechanism of genomic imprinting, demonstrating a necessary role for a non-coding RNA transcript in the silencing of an imprinted gene cluster in mice.   view more (2006-05-15)

New gene regulation mechanism discovered
Researchers at Cold Spring Harbor Laboratory have discovered a new kind of messenger RNA molecule that is converted from non-protein coding status to protein coding status in response to cellular stress such as viral infection.   view more (2005-10-21)

Protein splicing upsets the DNA colinearity paradigm
Understanding medical research problems often relies on the direct, linear relationship between the sequence of a protein and the DNA encoding that protein.   view more (2006-09-08)

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)

'Pregnant' protein-coding genes carry RNA 'babies'
Scientists from the Chinese Academy of Sciences have performed a comprehensive analysis of small, non-protein-coding RNAs in the model nematode, C. elegans.   view more (2006-01-10)

Protein binds whenever it can
Dutch cancer researcher Joost Martens has discovered that the protein p300, which plays an important role in the correct transcription of DNA to RNA, can bind to DNA at several sites. The protein can also occupy a position in various complexes, each with its own protein composition. This knowledge... view more (2003-06-24)

Coding for arthropods-what's so special about insects and spiders?
The central dogma of molecular biology is that DNA makes RNA makes protein. This relies on a specific underlying code which relates given triplets of RNA nucleotides into specific amino acids.   view more (2006-04-25)

Evolutionary scrap-heap challenge: Antifreeze fish make sense out of junk DNA
Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA.   view more (2006-04-04)

Scientists discover role for dueling RNAs
Researchers have found that a class of RNA molecules, previously thought to have no function, may in fact protect sex cells from self-destructing.   view more (2006-11-17)

Chicken genome gives insights into human genome
The draft sequence of the wild chicken, Gallus gallus, will be published in the Dec 9th issue of Nature (cover story). The analysis of this genome is not about getting bigger eggs and tastier chicken - it's giving scientists surprising insights into the human genome. Researchers can use these new... view more (2004-12-06)

Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.   view more (2005-09-30)

Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription
The distribution of the four nucleotides along the DNA sequence encodes the genetic information in living systems. However, do nucleic acids possess other attributes that contribute to their biological functions?   view more (2007-03-14)

Identification of Functional SNPs - Advances in Determining Genetic Susceptibility to Disease
Researchers at Oxford University's Wellcome Trust Centre for Human Genetics have developed a methodology to evaluate concurrently the functional significance of the millions of non-coding polymorphisms that exist in the human genome. Ultimately, this method will aid the progress in determining... view more (2003-04-07)

Remote control for human growth hormone gene expression
Researchers at the University of Pennsylvania School of Medicine recently discovered a novel mechanism that works over an extensive genomic distance and controls the expression of human growth hormone (hGH) in the pituitary gland.   view more (2006-08-14)

Brain gene shows dramatic difference from chimp to human
One of the fastest-evolving pieces of DNA in the human genome is a gene linked to brain development.   view more (2006-08-17)

UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD.   view more (2005-10-20)

New plant study reveals a 'deeply hidden' layer of the transcriptome
Cells keep a close watch over the transcriptome - the totality of all parts of the genome that are expressed in any given cell at any given time.   view more (2007-12-28)

A real time look at interactions between RNA and proteins
For the first time, researchers can now peer inside intact cells to not only identify RNA-binding proteins, but also observe-in real-time-the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions.   view more (2006-01-30)

Rehydrate - your RNA needs it
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent.   view more (2006-08-23)

Study finds protein is required for human chromosome production
Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified an elusive protein that performs a necessary step in the production of human chromosomes.   view more (2005-10-13)

Oregon team zeroes in on RNA-binding in myotonic dystrophy
University of Oregon researchers have shed new light on the function of an RNA-regulating protein known as muscleblind, which when it misbehaves and binds to rogue RNA can lead to disease affecting roughly one in 8,000 people.   view more (2007-11-08)

Facial models allow "band-efficient" video communication
Is it possible to combine a three-dimensional wire model of a face with real pictures of the same face? And is it possible to get the computer that is forming the new image to follow the face even when the person in question makes sudden movements or partially covers her face with her hand? These... view more (2002-02-11)

New insights into how the oncogenic protein c-Myc regulates cell growth

Researchers find 'secret weapon' used by SARS virus
In 2003, the highly contagious and often-deadly mystery disease now called SARS emerged explosively out of Southern China. It eventually killed an estimated 916 people in Asia, Europe, and North and South America-nearly one in ten of those it infected.   view more (2006-08-08)
