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).

Vaccine and drug combination cuts melanoma recurrence by half

The combination of a vaccine and a drug, which both harness the immune system to attack cancer cells, has proven successful in cutting the risk of skin cancer recurrence by 49 percent, a new study shows.

New SMArT platform improves safety of CRISPR gene editing

A team of researchers led by Luigi Naldini at the San Raffaele Telethon Institute for Gene Therapy (SR-Tiget) has developed a new strategy to significantly improve the precision and safety of CRISPR-Cas9 gene editing in human blood stem cells, potentially overcoming one of the major barriers limiting broader clinical application of genome editing therapies.

Mesenchymal drift may explain how aging cells lose their identity

Mesenchymal drift may help explain how cells lose stable identity and acquire pro-fibrotic, inflammatory mesenchymal traits during aging. The review proposes MD as a unifying framework that links multiple hallmarks of aging and highlights partial reprogramming as a potential, but still preclinical, way to counteract this process.

Review explores diagnosis and management of perioperative anaphylaxis during anesthesia

Perioperative anaphylaxis is a rare, life‑threatening condition during anesthesia. The unique setting – multiple drugs, patient draping, and altered physiology – causes higher mortality than anaphylaxis elsewhere.

Grant funds research into molecular memories behind exaggerated fear

Experiencing a traumatic event sometimes produces long-lasting biological changes that can lead to an exaggerated fear response to future stressful events, such as what occurs in individuals with post-traumatic stress disorder (PTSD).

Scientists uncover shared gene signatures that reveal how mammals age

Researchers mapped more than 11,000 transcriptomes across mice, rats, macaques, and humans, revealing conserved molecular signatures of aging and mortality across tissues, species, and cell types. The study developed interpretable transcriptomic clocks that track age, mortality-related molecular change, chronic disease signals and responses to lifespan-altering interventions.

New model reveals how chromosomes reorganize during cell replication

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

Brain transposons may influence aging and neurodegenerative disease progression

Transposable elements (TEs), also called transposons, are DNA sequences capable of moving or replicating from one location to another within a genome.

Study uncovers a biological link between chronic oral inflammation and female fertility

Chronic oral inflammation may impair female fertility by triggering a systemic immune response that affects the ovaries.

New nutrient-sensing mechanism offers hope for neurodegenerative diseases

Researchers from the University of Cambridge highlight new ways that neurons and many cell types use to sense nutrients - opening potential novel therapeutic avenues for disorders such as Alzheimer's and Parkinson's disease.

New colorectal cancer screening guidelines emphasize advanced stool tests

With colorectal cancer a growing concern among younger people, the American Cancer Society has endorsed two new types of stool tests to encourage people to get screened while also recommending a limited role for new blood tests many patients find appealing.
