DNA News and Research

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).

Fruit fly study sheds light on how new genes become functional

Most genes are ancient and shared across species. But a small subset of genes are relative newcomers, spontaneously emerging from stretches of DNA that once encoded nothing at all.

Underactive thyroid linked to increased risk of small intestinal bacterial overgrowth

People with an underactive thyroid may have an increased risk of developing small intestinal bacterial overgrowth (SIBO), a risk that may be reduced with thyroid hormone treatment, according to a study being presented Saturday at ENDO 2025, the Endocrine Society's annual meeting in San Francisco, Calif.

Uncovering the hidden architecture of the genome in three dimensions

In biology textbooks and beyond, the human genome and DNA therein typically are taught in only one dimension. While it can be helpful for learners to begin with the linear presentation of how stretches of DNA form genes, this oversimplification undersells the significance of the genome's 3D structure.

Exploring the roles of orphan nuclear receptors in MASLD pathogenesis

Metabolic dysfunction-associated steatotic liver disease (MASLD), affecting approximately 30% of the global population, represents a spectrum of liver disorders ranging from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, and cirrhosis.

New biosensor uses light and AI to detect cancer in its earliest stages

Dr. Ho Sang Jung and his research team from the Advanced Bio and Healthcare Materials Research Division at the Korea Institute of Materials Science(KIMS) have developed an optical biosensor capable of detecting trace amounts of cancer cell DNA in the bloodstream with high sensitivity, enabling early cancer diagnosis.

Understanding resistance to EGFR targeted therapies in head and neck cancers and breast cancer

A new review was published in Volume 16 of Oncotarget on June 25, 2025, titled "Challenges and resistance mechanisms to EGFR targeted therapies in head and neck cancers and breast cancer: Insights into RTK dependent and independent mechanisms."

Researchers uncover molecular switch controlling DNA packing in cell division

If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged.

Psilocybin may have potential to revolutionize anti-aging therapies

As revenues from the anti-aging market-- riddled with hope and thousands of supplements–– surged past $500 million last year, Emory University researchers identified a compound that actively delays aging in cells and organisms.

Artificial intelligence tracks aging and damaged cells through high resolution imaging

A combination of high-resolution imaging and machine learning, also known as artificial intelligence (AI), can track cells damaged from injury, aging, or disease, and that no longer grow and reproduce normally, a new study shows.

Oral lysozyme can restore healthy gut balance and reverse signs of vascular aging

A study reveals that lysozyme (LYZ) plays a pivotal role in age-related blood vessel inflammation by influencing gut bacteria.

New RNA-based liquid biopsy detects early colorectal cancer with high accuracy

Liquid biopsies are tests that detect signs of cancer through a simple blood draw. Unlike traditional biopsies, which require removing a piece of tissue, a liquid biopsy typically looks for mutations or modification changes in fragments of DNA from cancer cells circulating in the blood.
