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 solve decade-old mystery that could lead to development of new treatments for TB

Scientists have solved a decade-old mystery that could eventually lead to the development of earlier treatments for one of the world's deadliest diseases, which affects up to 2 billion people.

PARP inhibitors may have efficacy in selected TNBC patients outside of germline BRCA mutation

The investigational PARP inhibitor talazoparib caused regression of patient-derived xenografts (PDXs) of triple-negative breast cancers (TNBC) that had BRCA mutations and also those that did not have BRCA mutations but had other alterations in DNA damage-repair pathways.

Scientists make breakthrough by suppressing aflatoxin-producing fungus in groundnut

Scientists at the Donald Danforth Plant Science Center, in St. Louis, MO and their collaborators at the International Crops Research Institute for the Semi-Arid Tropics in Hyderabad, India, United States Department of Agriculture and Louisiana State University have made a significant research breakthrough by suppressing the aflatoxin-producing fungus in groundnut.

Our chromosomes also wrinkle with age, research shows

Grey hair, wisdom, and wrinkles on our skin mark us as we age, but it's the more subtle changes beneath the surface that make us old. Now, researchers have discovered that our chromosomes also wrinkle with age, changing how our immune system renews itself.

GHIT Fund announces US$16.7 million to support development of new drugs, vaccines and diagnostics

The Global Health Innovative Technology Fund, a unique Japanese public-private partnership formed to battle infectious diseases around the globe, today announced US$16.7 million to support development of new compounds for fighting malaria and tuberculosis, a leishmaniasis vaccine and drug, and a treatment for a long-ignored flesh-eating infection.

Powerful toolkit uncovers rare tumor suppressor genes

A new statistical model has enabled researchers to pinpoint 27 novel genes thought to prevent cancer from forming, in an analysis of over 2000 tumors across 12 human cancer types. The findings could help create new cancer treatments that target these genes, and open up other avenues of cancer research.

SU2C and its collaborators announce four teams to intercept cancer at earliest stages

Stand Up To Cancer, joined by the Lustgarten Foundation for Pancreatic Cancer Research, LUNGevity, and the American Lung Association, announced today four teams of top researchers who will carry out an attack on cancers of the lung and pancreas using a radical new approach of “interception” of cancers at very early stages, when they can be more successfully treated.

Researchers investigate how component of soy may suppress breast cancer development

A University of Arizona Cancer Center research team is engaged in a series of studies to investigate how genistein, a component of soy foods, might suppress the development of breast cancer.

Study demonstrates beneficial effects of calorie-restricted diet in mice

Caloric restriction diets have been associated with various health benefits, but their effects on the skin have not been previously demonstrated. Research conducted at the University of São Paulo (USP) in Brazil shows that controlling calories helps mice live longer, although it reduces the reserves of fat in adipose tissue needed to keep the body warm.

New gene drive approach helps pinpoint combination therapies against fungal pathogens

Candida albicans is a notorious human fungal pathogen that causes thrush and serious systemic infections. Opportunistic C. albicans fungi, which often live inconspicuously in the normal flora of human skin and gut, can switch from their harmless stealth mode to become aggressive pathogens, especially in people whose immune systems are already compromised by pre-existing diseases or harsh drug therapies.

NASA’s “Twins Study” explores the effects space travel has on the human body

Preliminary results from NASA’s Twins Study have revealed some of the bodily changes that occurred in an astronaught, who spent almost one year in space, compared with his twin brother, who remained on earth.

Researchers isolate new molecule suitable for control of contact allergies

Researchers from the University of Bonn have isolated a molecule that is suitable for the control of contact allergies. The study illuminates a central immune mechanism, which may also play a role in other inflammatory diseases such as arthritis or arteriosclerosis.

Researchers identify important mechanism of epigenetic gene regulation

How can defective gene activity, which can ultimately lead to cancer, be avoided? Researchers at the University of Zurich have now identified a mechanism how cells pass on the regulation of genetic information through epigenetic modifications. These insights open the door to new approaches for future cancer treatments.

Genome-wide molecular tests can guide treatment in recurrent glioblastoma, study shows

Several patients with recurring glioblastoma, a deadly brain cancer, survived for more than a year in a clinical trial believed to be the first to use comprehensive DNA and RNA sequencing of a patient's tumor to inform treatment for these patients in real-time.

Novel laboratory model may shine light on development of pediatric high-grade glioma

Pediatric high-grade glioma is the primary cause of cancer death in children. Genesis of these tumors is believed to be driven by mutations in proteins that disrupt fundamental mechanisms governing the development of the human brain.

‘Precision Medicine’ may not always be so precise when applied to diverse populations, study says

Precision Medicine in oncology, where genetic testing is used to determine the best drugs to treat cancer patients, is not always so precise when applied to some of the world's more diverse populations, according to a study led by the Translational Genomics Research Institute, an affiliate of City of Hope, and the Keck School of Medicine of the University of Southern California.

Sleeper cells in cancerous tumors can be destroyed if they possess specific defects

In many metastasized types of cancer, disseminated tumors grow back despite successful chemotherapy. As a research team under the direction of the University of Bern, Switzerland, has now discovered, this is because of isolated cancer cells that survive the chemotherapy due to a phase of dormancy.
