DNA News and Research

RSS

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Scientists discover mechanism used by A20 protein to combat inflammation

Scientists affiliated with VIB and UGent have discovered a mechanism used by the protein A20 to combat inflammation. This could be a very important point of focus in the search for a treatment for autoimmune diseases such as Rheumatoid Arthritis, in which the patient suffers from chronic, uncontrolled inflammation.

PARP-1 plays a major role in controlling AR function in prostate cancer patients

A newly discovered function of PARP-1 could be the key to more effective therapeutics to treat advanced prostate cancer patients, a recent preclinical study published in Cancer Discovery by Jefferson's Kimmel Cancer Center researchers suggests.

Chronic kidney disease changes the composition of intestinal bacterial microbes

Chronic kidney disease changes the composition of intestinal bacterial microbes that normally play a crucial role in staving off disease-causing pathogens and maintaining micronutrient balance, according to UC Irvine researchers.

Study sheds light on fundamental cellular process

Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes-and revealing new clues as to what happens when this process goes awry.

BDNF deletion plays a critical role in psychiatric disease and obesity

McGill researchers have identified a small region in the genome that conclusively plays a role in the development of psychiatric disease and obesity. The key lies in the genomic deletion of brain-derived neurotrophic factor, or BDNF, a nervous system growth factor that plays a critical role in brain development.

New blood test can read genetic changes in prostate cancer

Scientists have designed a blood test that reads genetic changes like a barcode - and can pick out aggressive prostate cancers by their particular pattern of gene activity.

Merck receives non-exclusive license to use Delphi StabyExpress technology

Delphi Genetics SA has announced today a broad licensing agreement with a subsidiary of Merck & Co., Inc., known as MSD outside the United States and Canada, for the use of the StabyExpress technology, which allows high yield, cost effective protein expression without the use of antibiotics.

Researchers discover smallest and fastest-known RNA switches

A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs.

Progenra’s USP7 and USP47 exert non-overlapping anticancer cell effects

Researchers at Progenra, Inc. announce the advanced online publication of the article "Selective Dual Inhibitors of the Cancer-related Deubiquitylating Proteases USP7 and USP47." The new article presents evidence of a therapeutic benefit resulting from dual inhibition of USP7 and a related enzyme, USP47.

New ways of how biological clock's neurons use electrical activity to keep behavioral rhythms in order

Biologists from New York University have uncovered new ways our biological clock's neurons use electrical activity to help keep behavioral rhythms in order. The findings, which appear in the journal Current Biology, also point to fresh directions for exploring sleep disorders and related afflictions.

Translational Genomics Research Institute creates new center for rare childhood disorders

The Translational Genomics Research Institute (TGen) today announced the creation of a new center that could have life changing effects on the lives of potentially thousands of children and their families.

Gene-silencing mechanism may occur later in life and lead to cancer

There are some genes that are only activated in the very first days of an embryo's existence. Once they have accomplished their task, they are shut down forever, unlike most of our genes, which remain active throughout our lives. EPFL scientists have unveiled part of this strange mechanism. The same process, accidentally initiated later in life, could be responsible for many kinds of cancer.

Skin's outmost layer is the first line of defense against UV radiation

Reinhold Dauskardt, PhD, of Stanford's Department of Materials Science and Engineering has been studying skin for years. But when he sent his students to look for data on the mechanical properties of skin, they came back empty-handed. A lot was known about skin structure and disease, but few papers actually talked about its mechanical function - its ability to stretch and resist tension without tearing.

BUSM leads genome-wide evaluation of genetic variants associated with Parkinson's disease

Boston University School of Medicine investigators have led the first genome-wide evaluation of genetic variants associated with Parkinson's disease (PD). The study, which is published online in PLOS ONE, points to the involvement of specific genes and alterations in their expression as influencing the risk for developing PD.

Perplexing evolutionary history of malaria transmitting mosquito species

An African mosquito species with a deadly capacity to transmit malaria has a perplexing evolutionary history, according to discovery by researchers at the Fralin Life Science Institute at Virginia Tech.

Two genes linked to increased risk of diabetes-associated kidney disease

An international group of researchers has discovered two genes that increase the risk of developing diabetes-associated kidney disease.

Mouse genome consists of 10-nm chromatin fibres

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings are published in EMBO reports, reveal that the mouse genome consists of 10-nm chromatin fibres but did not find evidence for the wider 30-nm fibres that were previously thought to be important components of the DNA architecture.
