Roles of DNA packaging protein revealed by Einstein scientists
Scientists at Albert Einstein College of Medicine of Yeshiva University have found that a class of chromatin proteins is crucial for maintaining the structure and function of chromosomes and the normal development of eukaryotic organisms. view more (2009-02-13)
Study validates means to measure possible leukemia marker
A study led by cancer researchers at The Ohio State University has validated a method for reliably measuring variations in certain proteins that may make good biomarkers in chronic leukemia patients. view more (2009-05-01)
Researcher Solves Mystery about Proteins that Package the Genome
A Florida State University College of Medicine researcher has solved a century-old mystery about proteins that play a vital role in the transfer of the human genetic code from one cell to another. The discovery could lead to finding new ways to help the body fight a variety of diseases, including cancer. view more (2009-10-08)
Brain DNA 'remodeled' in alcoholism
Reshaping of the DNA scaffolding that supports and controls the expression of genes in the brain may play a major role in the alcohol withdrawal symptoms, particularly anxiety, that make it so difficult for alcoholics to stop using alcohol. view more (2008-04-02)
Novel enzyme offers new look at gene regulation
Scientists at the University of North Carolina at Chapel Hill have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent. view more (2005-12-21)
Gene-regulating enzyme is also a target for anti-depressive drugs
In 2005, professor Ramin Shiekhattar, Ph.D., at The Wistar Institute and his colleagues reported details about an enzyme involved in appropriately repressing sets of neuronal genes in non-neuronal cells. view more (2006-06-26)
Tolerance to inhalants may be caused by changes in gene expression
Changes in the expression of genes may be the reason why people who abuse inhalants, such as spray paint or glue, quickly develop a tolerance, biologists at The University of Texas at Austin have discovered. view more (2007-10-18)
Linking DNA and histone methylation
In the May 15th issue of G&D, Dr. Michael Carey (UCLA's Jonsson Comprehensive Cancer Center) and colleagues lend new insight into the mechanism of epigenetic silencing of euchromatic genes. view more (2007-04-30)
Epigenetic research uncovers new targets for modification enzymes
Enzymes regulating genetic expression can be just as important as the genome itself, increasing evidence shows. The expanding field of epigenetics focuses on the multiple influences on DNA and surrounding molecules that determine whether genes are turned on or off during development and disease processes. view more (2008-04-28)
ISU researcher identifies key function in protein, cell transcription
When cells decide to make proteins, key building blocks of all organisms, they need to know where to start reading the instructions for assembling them. view more (2009-05-04)
Molecular partners required for appropriate neuronal gene repression
In their efforts to understand the complex biology of life, scientists often seek to isolate individual elements of the puzzle for study, to break the problem down to a more manageable size. Single genes and molecules are closely analyzed to better understand their specific interactions with other single entities within larger systems. view more (2005-08-04)
Gene-transcription machinery seen poised for action, held in check until needed
For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes. view more (2007-07-26)
University of Minnesota researchers take new look at cellular suicide
Like a bodyguard turned traitor, a protein whose regular job is to help repair severed DNA molecules will, in some cases, join forces with another protein to do the opposite and chop the DNA to bits. view more (2006-07-07)
UT Southwestern researchers find alterations in brain's circuitry caused by cocaine
Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction. view more (2005-10-24)
OMRF scientists discover promising new path for treating traumas
A discovery by scientists at the Oklahoma Medical Research Foundation could help save lives threatened by traumatic injuries like those sustained in car crashes or on the battlefield. The work also holds potential for treating severe infectious diseases and diabetes. view more (2009-10-26)
Scientists Clarify a Mechanism of Epigenetic Inheritance
Although letters representing the three billion pairs of molecules that form the "rungs" of the helical DNA "ladder" are routinely called the human "genetic code," the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code. view more (2008-04-23)
Revealing the machinery underlying the 'plastic' juvenile brain
Among the central mysteries of neurobiology is what properties of the young brain enable it to so adeptly wire itself to adapt to experience—a quality known as plasticity. view more (2007-03-01)
Large DNA stretches, not single genes, shut off as cells mature
Experiments at Johns Hopkins have found that the gradual maturing of embryonic cells into cells as varied as brain, liver and immune system cells is apparently due to the shut off of several genes at once rather than in individual smatterings as previous studies have implied. view more (2009-01-20)
Enzyme complex thought to promote cancer development can also help prevent it
In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker" and, in the process, may have discovered an agent that can suppress cancer development. view more (2005-10-14)
Researchers find protein that silences genes
A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off - in this case, the turning off of thousands of nearly identical genes in a hybrid plant. view more (2006-05-08)
