DNA News and Research

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).

RNA switches can better equip and regulate viruses for many therapeutic applications

Numerous viruses are used in the service of science today. They serve as gene taxis to transfer therapeutic genes into body cells or as therapeutic viruses targeted to infect and destroy cancer cells. For such applications, the viruses are often equipped with additional genes, such as for immune mediators or for proteins inducing programmed cell death. However, these gene products can harm the body if they are released at the wrong moment or at excessive levels.

UC San Diego, iSAEC partner to study genetics of drug induced renal injury

The International Serious Adverse Events Consortium (iSAEC) announced today it will collaborate with the University of California, San Diego School of Medicine and UC San Diego Skaggs School of Pharmacy and Pharmaceutical Science to research the genetics of drug induced renal injury (DIRI).

Mof protein plays a key role in epigenetics of stem cells

How do stem cells preserve their ability to become any type of cell in the body? And how do they "decide" to give up that magical state and start specializing? If researchers could answer these questions, our ability to harness stem cells to treat disease could explode. Now, a University of Michigan Medical School team has published a key discovery that could help that goal become reality.

CIRT to determine whether methotrexate can reduce heart attacks, strokes and CVD deaths

An international multi-site trial has launched to determine whether a common anti-inflammatory drug can reduce heart attacks, strokes, and deaths due to cardiovascular disease in people at high risk for them. This study is being supported by the National Heart, Lung, and Blood Institute (NHLBI), a part of the National Institutes of Health.

Chemists develop new lab test to examine how DNA damage disrupts protein synthesis

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.

Gene therapy applied to peripheral arterial disease

Hepatocyte growth factor gene therapy could be used to treat patients with severe peripheral arterial disease, suggest results of a phase I clinical trial.

New silicon chips help identify patients with lupus

Researchers at the Stanford University School of Medicine and Intel Corp. have collaborated to synthesize and study a grid-like array of short pieces of a disease-associated protein on silicon chips normally used in computer microprocessors.

ACS National Meeting & Exposition focuses on DNA wires and their potential use in identifying diseases

In a discovery that defies the popular meaning of the word "wire," scientists have found that Mother Nature uses DNA as a wire to detect the constantly occurring genetic damage and mistakes that ― if left unrepaired ― can result in diseases like cancer and underpin the physical and mental decline of aging.

Computer simulations shed light on dynamic structure of major target for anti-cancer drugs

Using advanced computer simulations, University of Utah College of Pharmacy researchers have produced moving images of a protein complex that is an important target for anti-cancer drugs.

Pyruvate kinase M2 fuels tumor growth by influencing H3 histone protein

A metabolic protein that nourishes cancer cells also activates tumor-promoting genes by loosening part of the packaging that entwines DNA to make up chromosomes, a team led by scientists at The University of Texas MD Anderson Cancer Center reports in the Aug. 16 issue of Cell.

Study helps explain how large DNA viruses undergo rapid evolution

Scientists have discovered that poxviruses, which are responsible for smallpox and other diseases, can adapt to defeat different host antiviral defenses by quickly and temporarily producing multiple copies of a gene that helps the viruses to counter host immunity.

New DNA sequencing tests improve ability to analyze genetic disorders

Scientists at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School (UMDNJ-NJMS) have developed new DNA sequencing tests that hold significant promise for decreasing costs associated with diagnosing cancer and hereditary diseases, including cysticfibrosis.

Pan-fried red meat associated with increased risk of advanced prostate cancer

Research from the University of Southern California (USC) and Cancer Prevention Institute of California (CPIC) found that cooking red meats at high temperatures, especially pan-fried red meats, may increase the risk of advanced prostate cancer by as much as 40 percent.
