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).

Aging brains lose key proteins despite intact genetic blueprints

An international research team involving the Leibniz Institute on Aging - Fritz Lipmann Institute (FLI) in Jena, the Scuola Normale Superiore Pisa, and Stanford University has discovered that in the aging brain, certain proteins are lost even though their mRNA blueprints remain intact.

New insights into how SETD2 shapes immunity and disease

The emerging role of SETD2 in regulating immune cell function is shedding light on potential therapeutic strategies for a range of immune-related diseases.

CRISPR screening uncovers microproteins involved in fat storage

The obesity rate has more than doubled in the last 30 years, affecting more than one billion people worldwide.

Researchers uncover dozens of traits driven by maternal versus paternal genes

Researchers developed a high-accuracy method to infer whether genetic variants come from the mother or father without needing parental genomes, analysing 286,666 UK Biobank participants. They uncovered over 30 parent-of-origin effects on traits from growth and metabolism to diabetes, many showing opposite effects depending on parental source.

Study links epigenetic markers to cardiovascular risk in type 2 diabetes

People with type 2 diabetes are up to four times more likely to have heart attacks, strokes, anginas and other coronary heart diseases than healthy people.

Scientists map the genes behind diet and dementia risk

Researchers established a high-quality genetic dataset from the MIND diet trial, enabling new studies of gene–diet interactions in cognitive health. This resource allows deeper investigation into why individuals respond differently to dietary interventions targeting dementia risk.

Prime editing reverses symptoms of severe childhood neurological disease

Scientists use a precise form of gene editing called prime editing to correct the most common genetic mutations that cause alternating hemiplegia of childhood, a rare and severe neurological disorder that begins in infancy.

Targeting lactate metabolism offers new avenues for cancer treatment

Lactic acid (LA) has transitioned from being perceived as a mere glycolytic waste product to a pivotal regulator of tumor-immune crosstalk.

Researchers solve longstanding mystery of protein release in cells

It's known as biology's central dogma: All living organisms' genetic information is stored in DNA, which is transcribed into RNA, which is translated into proteins that perform nearly all essential tasks in a cell.

Starfish compound overcomes drug resistance in prostate cancer models

Researchers identified that triterpene glycosides from the starfish Solaster pacificus can kill drug-resistant prostate cancer cells in vitro by bypassing common resistance pathways. CuC1 showed synergy with existing chemotherapies, though with only moderate selectivity for cancer cells.

Understanding how long non-coding RNAs control gene expression in cancer

Long non-coding RNAs (lncRNA) are a type of RNA molecule that do not carry instructions to make proteins. Instead, they influence how other genes are expressed.

AI model advances prediction of microsatellite status in cancer

One in every three people is expected to have cancer in their lifetime, making it a major health concern for mankind.

New insights into how genes influence frailty in older adults

A new study has identified genetic variants linked to brain function, immune defense and metabolism that contribute to the development of frailty in older people.

Subtle genetic shifts in brain enzyme offer clues to human evolution

The evolutionary success of our species may have hinged on minute changes to our brain biochemistry after we diverged from the lineage leading to Neanderthals and Denisovans about half a million years ago.

Cannabis use disorder triples five-year risk of oral cancer

Research shows cannabis use disorder triples the risk of oral cancer, challenging perceptions of cannabis safety and prompting calls for health screenings.

HIV trial points to semaglutide as a new anti-aging contender

Once-weekly semaglutide significantly slowed epigenetic aging in adults with HIV-associated lipohypertrophy, as measured by multiple DNA methylation clocks in a randomized controlled trial. These exploratory findings suggest GLP-1 receptor agonists could impact biological aging but require further validation in broader populations.

Programmable Chromosome Engineering systems enable precise DNA manipulations

A team of Chinese researchers led by Prof. GAO Caixia from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences has developed two new genome editing technologies, known collectively as Programmable Chromosome Engineering (PCE) systems.

New research unveils vast influence of B vitamins on health and disease

Eight essential nutrients make up the suite of B vitamins also known as the B complex. Researchers from Tufts University and elsewhere have revealed that these B vitamins influence a vast spectrum of human health and disease, including cognitive function, cardiovascular health, gastric bypass recovery, neural tube defects, and even cancer.
