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).

Moderate exercise can influence the inflammatory responses of macrophages, research shows

Researchers have long known that moderate exercise has a beneficial impact on the body's response to inflammation, but what's been less understood is why.

Innovative method to map specific DNA markings could be used for early cancer detection

Researchers from the Perelman School of Medicine at the University of Pennsylvania have invented a new way to map specific DNA markings called 5-methylcytosine (5mC) which regulate gene expression and have key roles in health and disease.

COVID-19 susceptibility mechanism discovered using a newly created tool

Researchers have discovered a mechanism for COVID-19 susceptibility using a newly created tool. The tool, GASPACHO, captures dynamic changes in gene expression along the innate immune response, allowing researchers to identify genes and molecular pathways associated with disease risk that have previously been too complex to detect or interpret.
