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).

Novel DNA plasmid therapy shows high success rate in treating chronic pain in dogs

Elenagen™, a novel DNA plasmid therapy that previously demonstrated high clinical benefit and low toxicity in cancer patients, has now shown significant promise in alleviating chronic pain demonstrating a 90% success rate.

Toti-N-Seq breakthrough enables universal and scalable single-cell profiling

The rapid advancement of single-cell and single-nucleus RNA sequencing (sc/snRNA-seq) has opened unprecedented windows into cellular diversity, yet existing methods for multiplexing samples struggle with scalability and accuracy.

Blocking a single gene disrupts vitamin D metabolism and cancer pathways in new cell study

Researchers identified SDR42E1 as a key regulator of vitamin D absorption and sterol metabolism in colorectal cancer cells. Disruption of this enzyme altered cancer-related pathways and cell viability, highlighting its potential as a therapeutic target.

APOE ε4 variant reveals hidden risk factors beyond Alzheimer’s

Researchers discovered that people carrying the APOE ε4 gene variant share a unique immune-related protein signature across their blood, brain, and cerebrospinal fluid—regardless of neurodegenerative disease diagnosis. This signature reveals a fundamental, disease-independent vulnerability linked to APOE ε4, reframing our understanding of genetic risk in conditions like Alzheimer's, Parkinson’s, ALS, and FTD.

Study identifies mechanism that helps prevent cancer, neurodegeneration, and premature aging

Researchers at the University of Oxford and Nanyang Technological University, Singapore (NTU Singapore) have uncovered the mechanism by which cells identify and repair a highly toxic form of DNA damage that causes cancer, neurodegeneration, and premature aging.

Prime editing reverses symptoms of severe childhood neurological disease

Scientists use a precise form of gene editing called prime editing to correct the most common genetic mutations that cause alternating hemiplegia of childhood, a rare and severe neurological disorder that begins in infancy.

Gene editing in the brain offers hope for ultra-rare neurological disease

Scientists have corrected gene mutations in mice causing an ultra-rare disease by editing DNA directly in the brain with a single injection, a feat with profound implications for patients with neurological diseases.

New study identifies genes that shape human brain features

What makes the human brain distinctive? A new study published July 21 in Cell identifies two genes linked to human brain features and provides a road map to discover many more.

Blocking GAPDH aggregation protects brain cells and opens new path for stroke therapy

In a mouse model of acute ischemic stroke, researchers showed that inhibiting the aggregation of GAPDH, either genetically or with a novel peptide, significantly reduced brain damage and improved neurological function. The findings highlight GAPDH aggregation as a promising therapeutic target for stroke intervention.

Ancient viral DNA found to regulate human gene expression

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk", may actually play powerful roles in regulating gene expression.

Human eggs use a minimalist strategy to stay healthy for decades

Human eggs are some of the most patient cells in the body, lying dormant for decades until needed. A study published today in The EMBO Journal shows that the cells deliberately slow the activity of their internal waste disposal systems as they mature, most likely an evolutionary design which keeps metabolism low and damage at bay.
