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).

Study links antidepressant use and epigenetic aging to higher mortality risk in postmenopausal women

The impact of depressive symptoms, use of antidepressants, and epigenetic age acceleration (EAA) on mortality in postmenopausal individuals.

Stanford study finds low risk of secondary blood cancers after CAR-T cell therapy

A large study by researchers at Stanford Medicine has found that the risk of secondary blood cancers after CAR-T cell therapy -; a cell-based cancer treatment that exploded on the scene in 2017 as a treatment for intractable blood cancers -; is low, despite a Food and Drug Administration warning.

HiDEF-seq technique reveals the origins of DNA mutations in single strands

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including cancer.

Nasal microbiota composition predicts sepsis with high accuracy in ICU settings

The nasal microbiota of intensive care unit (ICU) patients effectively distinguishes sepsis from non-septic cases and outperforms analyzing the gut microbiota to predict sepsis, according to a new study published in Microbiology Spectrum, a journal of the American Society for Microbiology.

Human antibodies show promise against Black widow spider venom

There are various types of widow spiders, including black, red, and brown varieties in North and South America, the Australian redback spider, and several button spider species that inhabit South Africa.

Gut bacteria turn dietary phytate into health-boosting fatty acids, study shows

Study reveals that human gut bacteria, particularly Mitsuokella jalaludinii, efficiently degrade dietary phytate into short-chain fatty acids, enhancing health benefits through microbial synergy.

UD researchers pioneer universal, economical method for proteomics sample preparation

Proteins are workhorses that carry out most of the biological functions in our cells. While the genes we inherit from our parents, our so-called genome, are fixed and usually remain unchanged throughout our lives, proteins in our bodies are constantly changing, as we age, under different health conditions and upon stimulation, such as with medical treatment.

Understanding Crohn's disease through 'mini-gut' models

Cambridge scientists have grown 'mini-guts' in the lab to help understand Crohn's disease, showing that 'switches' that modify DNA in gut cells play an important role in the disease and how it presents in patients.

Precision-guided treatment boosts outcomes in children with high-risk cancers

Study reveals that precision-guided treatment (PGT) improves outcomes in high-risk pediatric cancer patients, but clinical adoption remains low due to physician uncertainty and lack of long-term survival data.

Efficient whole-gene insertions can be achieved with improved gene-editing technology

Scientists at the Broad Institute of MIT and Harvard have improved a gene-editing technology that is now capable of inserting or substituting entire genes in the genome in human cells efficiently enough to be potentially useful for therapeutic applications.
