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).

Australian-first twin study aims to to unlock new insights into immune health

An Australian-first study of twins will seek to find out why two genetically similar people respond differently to infections, diseases and treatments.

New genomic approach links rare immune cells to autoimmune disease risk

Much of how genetic risk leads to disease has remained hidden. In many cases, genetic variants linked to disease do not act on nearby genes along the chromosome.

Complete medaka genome sequence reveals repetitive DNA with biological significance

Researchers sequenced the genomes of three medakas, or Japanese rice fish, which are a common model organism used for biological research, nearly 10 and 20 years ago.

Cell village approach reveals genetic differences in cell fitness

How readily a cell divides and how well it survives is fundamental to life, shaping everything from organ size to the body's ability to withstand disease.

Penn State study identifies genetic regions linked to avian herpesvirus virulence

A highly contagious herpes virus causes Marek's disease, a deadly illness that mainly infects chickens. While it does not make people sick, the virus causes tumors and paralysis in chickens and, if unchecked, can spread rapidly through entire flocks.

UCLA researchers find strategy to improve prostate cancer therapies

UCLA researchers have identified a promising strategy to make a new class of targeted cancer therapies more effective against one of the deadliest forms of prostate cancer, potentially overcoming treatment resistance that has limited their success.

Study links ancient evolutionary pressures to severe COVID-19 risk

Every time a virus invades a person, it collides with thousands of years of human history. A study led by researchers at the USC Dornsife College of Letters, Arts and Sciences and Howard University suggests that some of the genes involved in the body's immune response today bear the marks of ancient battles with infectious diseases.

Using DNA sequencing for accurate identification of microbial infections in cystic fibrosis patients

Lung infections are a constant risk for people living with cystic fibrosis (CF), a life-threatening genetic disorder which impairs lung function, predisposes people to persistent airway infections and exposes them to acquiring multidrug resistant infections.

New analytical strategies can measure thousands of gut microbial proteins

The trillions of microorganisms living in our intestine influence our health, from digestion and metabolism to immunity.

Cells share universal on switches but evolve unique strategy to silence genes

The signals that cells use to switch genes on have remained almost unchanged across two billion years of evolution, but the ones used to switch genes off vary dramatically from one branch of life to another, according to a new study from the Centre for Genomic Regulation (CRG) in Barcelona.

AI-powered blood test detects liver cancer across distinct populations

Researchers at the Johns Hopkins Kimmel Cancer Center validated an artificial intelligence (AI)-powered blood test that accurately detected liver cancer in people from two geographically and biologically distinct populations and also uncovered the underlying biological signals that make the test effective.

Arginine boosts immune defenses against cancer and viral infections

The amino acid arginine helps to keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes.

TRF2 protein preserves muscle stem cell identity and regeneration

A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.

Genetic variants interact to increase early-onset atrial fibrillation risk

An estimated 10 million Americans have atrial fibrillation (AFib), according to the National Institutes of Health's National Heart, Lung, and Blood Institute.

ESCRT-III proteins play an unexpected role in protecting DNA bridges during cell division

Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect the two newly formed cells.

Accumulation of somatic mutations drives vascular damage in people with progeria

Hutchinson-Gilford progeria syndrome (HGPS) is a genetic disorder that causes remarkable premature aging.

Microbial metabolites could help improve functional cure rates for hepatitis B

Chronic hepatitis B (CHB) remains a major global challenge. Current therapies suppress HBV but rarely achieve functional cure (sustained HBsAg loss).

New computational technique traces ghost ancestry in modern human genomes

UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.

New OpenABE gene editor improves editing efficiency by up to 36 times

A joint research team led by Professor Daesik Kim (Department of Medicine, Sungkyunkwan University), along with Professor Yong-Sub Kim (University of Ulsan College of Medicine) and Professor Jae-Hyun Park (Sungkyunkwan University School of Medicine), has announced the development of 'OpenABE' (Open Adenine Base Editor).
