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).

Stanford scientists discover unexpected cancer resistance in aged mice

Old laboratory mice develop substantially fewer and less-aggressive lung tumors than younger animals in a new study led by Stanford University researchers.

Researchers achieve long-term remission with novel T cell therapies for HPV-related cancers

Researchers from Rutgers Cancer Institute, New Jersey's only National Cancer Institute (NCI) - designated Comprehensive Cancer Center, and RWJBarnabas Health, along with colleagues from the National Cancer Institute, a center of the National Institutes of Health, announced findings from two HPV-related studies that highlight the potential of novel T cell therapies to achieve long-lasting remission and complete tumor regression in patients with advanced epithelial cancers.

Green-synthesized nanoparticles enhance cidofovir's anticancer efficacy

In this study, led by Nahid Shahabadi from Razi University in Kermanshah, researchers developed an environmentally friendly approach to enhance the performance of cidofovir, a drug used to treat infections caused by DNA viruses. The work responds to the growing need for therapies that are safer, more effective, and better targeted.

Micro-RNA in sperm proves vital for human embryogenesis

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to the development of the embryo several days after conception. The findings, published in the journal Nature Communications, may in the long term contribute to better diagnosis and treatment of involuntary childlessness.

New drug combination gains Fast Track Designation for metastatic colorectal cancer

The U.S. Food and Drug Administration has granted Fast Track Designation to a new drug combination for metastatic colorectal cancer, following encouraging results from a clinical trial led in part by the University of Oklahoma Health Stephenson Cancer Center.

One-time CRISPR therapy safely lowers cholesterol and triglycerides in early trial

In a 15-patient, Phase 1 one, first-in-human trial, a one-time, CRISPR-Cas9 gene-editing therapy safely reduced LDL cholesterol and triglycerides in people with difficult-to-treat lipid disorders, according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

Uppsala researchers develop Trojan horse approach for medulloblastoma treatment

The malignant pediatric brain tumor medulloblastoma is driven by proteins deep within the cancer cells, for which there are often no effective drugs available.

Maternal type 1 diabetes may protect children from developing the disease

Findings suggest maternal T1D exposure leads to protective epigenetic alterations in children, influencing immune response and type 1 diabetes susceptibility.

Condensate-based strategy protects synthetic gene circuits across cell generations

Genetic engineers can design and assemble sophisticated gene circuits to program cells with new functions, but important signaling molecules can become diluted as these cells grow and divide, causing the synthetic gene circuits to lose their new functions.

Scientists uncover mechanism driving efficient protein deacetylation by Sir2 enzyme

Sir2, an enzyme belonging to sirtuins, has been effectively involved in the deacetylation of proteins. A tandem allosteric effect of reactant and product is responsible for the efficient deacetylation cycle of the Sir2 enzyme, reveal researchers from Science Tokyo.
