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).

Understanding how natural genetic variation contributes to adaptive responses to low oxygen

Humans are still evolving, and Tatum Simonson, PhD, founder and co-director of the Center for Physiological Genomics of Low Oxygen at University of California School of Medicine, plans to use evolution to improve healthcare for all.

Genetics of estrogen production linked to endometrial cancer risk in postmenopausal women

A study in eBioMedicine identifies genetic factors regulating blood estrone levels in postmenopausal women, linking specific genetic loci to an increased risk of endometrial cancer, highlighting the role of non-ovarian estrogen production in cancer development.

Breakthrough technique unveils secrets of "backtracking" in gene regulation

A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows.

Rucaparib and its major metabolite exhibit differential biological activity and synergy

Once they enter the body, drugs, apart from carrying out their therapeutic function, are biochemically transformed by the action of the metabolic machinery, a process that facilitates their expulsion.

Fungicide resistance: A global threat to human, animal, and plant health

Fungi can cause disease in both humans, animals, and plants. Every year, 1.5 million people die from fungal infections, and fungal attacks in food crops threaten food production.

DDT exposure found to alter sperm epigenome in humans

In a study that signals potential reproductive and health complications in humans, now and for future generations, researchers from McGill University, the University of Pretoria, Université Laval, Aarhus University, and the University of Copenhagen, have concluded that fathers exposed to environmental toxins, notably DDT, may produce sperm with health consequences for their children.

Hormonal steroids could make gonorrhea untreatable

You know that package warning that oral birth control won't prevent STIs? Well in the case of gonorrhea, the sexually transmitted bacterium that causes the disease can use those hormones to help it resist antibiotic attacks.

Higher dietary niacin intake linked to lower COPD risk, study finds

Recent research in Scientific Reports reveals a dose-response relationship between dietary niacin intake and reduced prevalence of chronic obstructive pulmonary disease (COPD), suggesting niacin's potential role in mitigating oxidative stress and inflammation in COPD patients.

Mitochondrial misfire sparks inflammation

Cells in the human body contain power-generating mitochondria, each with their own mtDNA - a unique set of genetic instructions entirely separate from the cell's nuclear DNA that mitochondria use to create life-giving energy.

Mitochondria on the move: New discovery could revolutionize treatment of brain diseases

The human brain is an organ that takes nearly from 20 to 25% of the energy the body needs. This high energy demand for neuronal functions depends on the transport and precise distribution of mitochondria — the energy-generating cell organelles — in each neuron.
