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).

Griffith research unlocks more about cancer

A research collaboration between Griffith and the Malaghan Institute in Wellington, New Zealand has made the discovery that mitochondria are capable of passing through the healthy membrane of a host cell into defective tumour cells, possibly kicking off the rapid proliferation of tumour cells which is the hallmark of cancer.

Researchers discover inherited genetic variations associated with treatment-related hearing loss

St. Jude Children's Research Hospital investigators have discovered inherited genetic variations that are associated with rapid hearing loss in young cancer patients treated with the drug cisplatin. The research appears in the current online issue of the scientific journal Nature Genetics.

Study links previously unknown genetic anomalies to breast cancer in African American family members

The "Jewels in our Genes" study, led by University at Buffalo researcher Heather Ochs-Balcom, has uncovered previously unknown segments of DNA shared by African American family members who have breast cancer. "The discovery of these regions supports our hypothesis that there are still undiscovered breast cancer genes that may be unique to African Americans," says Ochs-Balcom, PhD, a genetic epidemiologist in the UB Department of Epidemiology and Environmental Health.

CWRU researcher receives $3.9 million grant for HIV research

A researcher at Case Western Reserve University School of Medicine has been awarded $3.9 million to determine if the combination of the human immunodeficiency virus (HIV) and drug abuse is a double kick in the gut, leading to organ damage throughout the body.

Duke University researchers devise new method to activate genes with light

Duke University researchers have devised a method to activate genes in any specific location or pattern in a lab dish with the flip of a light switch by crossing a bacterium's viral defense system with a flower's response to sunlight.

Researchers develop quality assurance tool for genome editing

A research team at Boston Children's Hospital's Program in Cellular and Molecular Medicine has developed a quality assurance tool for scientists using genome-editing technologies like the increasingly popular CRISPR. The assay, called high throughput genome translocation sequencing (HTGTS), rapidly gauges—for any given gene—these technologies' accuracy and their risk for causing potentially dangerous genomic collateral damage.

Research finding could help predict the next outbreak of plague

Biologists at the University of Oslo, Norway, are now making a giant effort to identify the relationship between climate change, rat infestations, and the many major plague epidemics throughout history. The knowledge may be used to predict the next plague outbreak.

New study sheds light on anorexia nervosa

A study led by Howard Steiger, PhD, head of the Douglas Mental Health University Institute Eating Disorders Program, in Montreal, in collaboration with Linda Booij, a researcher with Sainte-Justine Hospital and an assistant professor at Queen's University, is the first to observe effects suggesting that the longer one suffers from active anorexia nervosa (AN), the more likely they are to show disorder-relevant alterations in DNA methylation.

New AGA guideline provides guidance to prevent HBV reactivation

Long-term immunosuppressive therapy can cause the hepatitis B virus (HBV) to become active, even in patients who are not aware that they are infected with the virus. A new guideline from the American Gastroenterological Association provides guidance to physicians and patients who use immunosuppressive agents for the treatment of a variety of disorders, including gastrointestinal, dermatologic, neurologic and rheumatologic, among others.

Investigators develop microbiome map of New York City subway system

The microbes that call the New York City subway system home are mostly harmless, but include samples of disease-causing bacteria that are resistant to drugs -- and even DNA fragments associated with anthrax and Bubonic plague -- according to a citywide microbiome map published today by Weill Cornell Medical College investigators.
