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).

Engineered CAR T cells show promise against myeloproliferative neoplasms

A new form of CAR T cell therapy has been designed to find and destroy the cancer-driving stem cells responsible for a group of blood cancers known as myeloproliferative neoplasms (MPNs), while leaving healthy blood cells unharmed, in new research led by UCL and University of Oxford researchers.

Advanced imaging technology unlocks exosome potential for disease diagnosis

Tiny particles released by most human cells may be promising targets for diagnosis and treatment of an array of diseases from cancer to Alzheimer's, but scientists have struggled to see them and study them in detail.

Study links DNA methylation to aggressive prostate cancer behavior

The prostate is the single organ most frequently afflicted by cancer in men. Prostate cancer affects approximately 4 million American men, with another 330,000 men expected to be diagnosed with the condition this year alone.

Vitamins A and D may support healthier lungs in asthma patients

Higher levels of circulating vitamin A are linked to better lung function in children and adults with asthma, while vitamin D shows similar benefits in adults, including slower biological ageing, finds the first study of its kind, published online in the respiratory journal Thorax.

SickKids study uncovers cell recovery mechanisms linked to stomach cancer

Few areas of the body face more daily stress and potential damage than the stomach, which must manage everything we swallow.

Highly-sensitive blood test detects hidden traces of pancreatic cancer

Northwestern Medicine scientists have demonstrated that a highly sensitive blood test can detect traces of pancreatic cancer missed by standard testing, potentially helping physicians identify patients whose disease is more likely to return even when scans appear reassuring.

Rare genetic condition offers new insights into human aging process

Scientists have discovered a rare genetic condition which causes people to age at a much faster rate, offering fresh insights into the aging process.

Japanese study links inherited genetic variants to multiple lung cancers

Lung cancer remains the leading cause of cancer-related deaths worldwide and is generally thought to arise from mutations acquired over a lifetime through environmental exposures.

New drug candidate reduces toxic protein clumps of Huntington's disease

An experimental drug has been shown to alleviate symptoms of Huntington's disease and extend lifespan in mouse models. Further studies are required to determine whether these results may also apply to humans.

Single DNA injection provides long-lasting weight loss in mouse study

Scientists at The Wistar Institute have shown that a single injection of a small, circular piece of genetic instructions can produce weight loss and blood glucose control in murine models that lasts up to 10 times as long as incretin-mimicking drugs like Ozempic and Wegovy.

Gut microbes emerge as potential players in estrogen-driven cancers

A new review maps how the endocrine-microbiome axis expands the estrobolome concept, showing that gut microbes may alter estrogen recycling, produce hormone-like metabolites, and shape inflammation and tissue environments in hormone-driven cancers. Human evidence remains mostly associative, so the authors call for causal models, longitudinal multi-omics, multi-kingdom profiling, and sex-stratified studies before microbiome-guided cancer strategies enter routine care.
