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).

New highly sensitive test for dengue virus developed using DNA star

Researchers have developed a new method for detecting and destroying the dengue virus that could be adapted for other viruses.

New targeted treatment to fight against deadly pancreatic cancer

Every day, more than 1200 people worldwide are told they have pancreatic cancer. Within 12 months, 80 per cent of them will have succumbed to the disease.

New tool uses tiny circuits made of DNA to identify cancer cells

A new cancer-detecting tool uses tiny circuits made of DNA to identify cancer cells by the molecular signatures on their surface.

DNA-modulated liquid droplets may explain how prion proteins clump

Researchers at the Federal University of Rio de Janeiro, in Brazil, have identified that the interaction between prion proteins and DNA may be behind the formation of protein amyloid aggregates and of the emergence of neurodegenerative diseases such as Creutzfeldt-Jakob disease and other spongiform encephalopathies.

Accelerating Medicines Partnership program for Parkinson’s disease launches new data portal

The Accelerating Medicines Partnership program for Parkinson's disease (PD) has launched a data portal to provide de-identified information collected from 4,298 PD patients and healthy controls to researchers working to develop effective therapies for the disease.

Extra DNA scooped up alongside cancer-causing genes helps drive tumor growth

One of the ways a cancer-causing gene works up enough power to turn a normal cell into a cancer cell is by copying itself over and over, like a Xerox machine.

Researchers turn to older treatment methods for new health challenges

The last thing anyone wants during a stay in the hospital is a hospital-acquired infection. Nosocomial infections, as they are called, are on the rise as more pathogens become resistant to drugs currently available.

Charcot-Marie-Tooth disease study unearths a new mechanism of neurodegeneration

Charcot-Marie-Tooth disease is an inherited neurodegenerative condition that affects 1 in 2500 individuals.

Researchers investigate a hospital outbreak in real time using high-resolution technique

On the European Antibiotic Awareness Day, researchers announce the results of a pilot study completed in record time. The initiative opens new perspectives for the control of bacterial infections in Portuguese hospitals.

Doughnut-shaped circles of ecDNA provide tumor cells with a malignant twist

Deoxyribonucleic acid or DNA encodes information, not only in its sequence but also in its shape.

Researchers identify a promising drug pair to attack deadly childhood brain cancers

Researchers have devised a new plan of attack against a group of deadly childhood brain cancers collectively called diffuse midline gliomas, including diffuse intrinsic pontine glioma, thalamic glioma and spinal cord glioma.

Impaired gene expression may influence aging via altered cellular metabolism

Throughout history, humans have been obsessed with finding a way to prevent aging and prolong life. Although the mechanisms have long eluded us, modern science is revealing more and more about the aging process. Now, researchers from Japan have uncovered new information about the genetic processes that may trigger age-related disorders, including low energy production and low cellular growth.

Circular DNA found in cancer cells supports their survival and resistance

A new study uncovers the role of the circular, 3D shape of extrachromosomal DNA in augmenting mutant oncogenes in cancer cells.

Rheumatoid arthritis linked to other diseases before and after diagnosis, shows study

A Mayo Clinic-led study involving 3,276 patients has found that people with inflammatory bowel disease, Type 1 diabetes or blood clots may be at increased risk of developing rheumatoid arthritis.

Subpopulations of tumor cells may exhibit diverging behaviors from bulk tumor

Subpopulations of tumor cells may exhibit diverging behaviors from the bulk tumor due to an alternate stress response that diverts tumor cells from apoptotic death.

Mayo Clinic, Hitachi to build North America's first carbon ion treatment facility

Mayo Clinic and Hitachi, Ltd. have reached an agreement in principle to build a carbon ion treatment facility as part of Mayo Clinic's recently announced integrated oncology facility which will be constructed at Mayo Clinic's campus in Jacksonville, Florida.

New database helps identify therapeutic targets to fight infectious diseases

Infectious diseases are caused by pathogenic microorganisms capable of entering, colonizing and growing within a host organism, thus producing an infection. Bacterial infections have been on the rise worldwide in recent years, but many mechanisms underlying bacterial pathogenesis are still poorly understood.

Researchers merge 3D/4D printing with a chemical process to produce 'living' materials

Repairing and reusing plastics and delivering cancer drugs more effectively are only two of many of the potential applications a new 3D/4D printing technology might have, thanks to the pioneering work of a research collaboration between UNSW Sydney and The University of Auckland.
