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).

Combination therapy improves progression-free survival in dMMR/MSI-H metastatic colorectal cancer

Patients with deficient DNA mismatch repair (dMMR) or microsatellite instability-high (MSI-H) metastatic colorectal cancer experienced a 58% reduction in the risk of disease progression or death when treated with atezolizumab plus modified FOLFOX6 and bevacizumab compared with atezolizumab alone, according to results from the NRG-GI004/SWOG S1610 COMMIT trial published recently in the Journal of Clinical Oncology.

Overactive brain immune response linked to rare, severe genetic epilepsy

An overactive immune response in the brain may play a role in Dravet Syndrome, a rare and severe genetic epilepsy that typically begins in infancy, according to Weill Cornell Medicine researchers.

New gene editing tool reduces Huntington's symptoms in mice

A gene editing tool designed to precisely rewrite the gene that causes Huntington's disease reduced toxic protein fragments and symptoms associated with the disease in mice, researchers at the University of Illinois Urbana-Champaign report.

A closer look at Parkinson’s brains finds tau where standard tests saw little

Researchers used single-molecule and super-resolution imaging to profile protein aggregates across six brain regions from 29 post-mortem donors, detecting high-intensity phosphorylated tau aggregates in the Parkinson’s disease putamen despite negligible conventional tau staining. PD cases with dementia showed greater tau burden than those without dementia, while the assay did not detect a PD-specific population of nanoscopic alpha-synuclein aggregates.

Researchers identify key barrier preventing self repair of heart cells

Specialized cells in our body make biological tradeoffs to do certain jobs. To support large and hardworking hearts that power our other organs, our heart cells evolved to be extremely efficient and resilient.

Landmark study identifies new genetic risk factors linked to fibromyalgia syndrome

In a landmark study published in Nature Medicine, an international team of researchers has identified new genetic risk factors associated with fibromyalgia syndrome.

Too little or too much iodine may push immunity off balance

This narrative review finds that adequate iodine supports thyroid hormone signaling, leukocyte metabolism, antioxidant defenses, and antimicrobial activity in humans and domesticated mammals. Both deficiency and sustained excess may impair immunity or promote thyroid inflammation, but precise immune-specific intake thresholds remain uncertain.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.

Taste preference genes drive overeating and metabolic disease risk

Ever wonder why some people crave sweets while others can take them or leave them? Preliminary findings from a new study suggest that people who carry certain genetic variants associated with a preference for sweet or fatty tastes not only tend to eat more of these foods but also have a higher risk of obesity and type 2 diabetes as a result.

Study links inherited genetics to cancer susceptibility and progression

Scientists have found the first direct evidence of the powerful role our genetic makeup plays in influencing our risk of cancer, with inherited genes interacting with acquired genetic mutations to shape how tumors evolve.

Iowa State study identifies potential new target for leukemia treatment

In leukemia's most aggressive forms, the blood cell factories in our bone marrow falter. Instead of dividing and multiplying at their usual prolific pace, generating hundreds of billions of new cells daily, some precursor cells stall out at an immature stage.

Taiwan Biobank data reveals ongoing natural selection in living humans

For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations, and ancient DNA.

Scientists discover master molecular switch for ginseng saponin production

Sanchi ginseng (Panax notoginseng) is a cornerstone of traditional Chinese medicine, prized for its saponins-bioactive compounds with anti-inflammatory, cardiovascular, and anticancer properties.

Study reveals how DNA misfolding causes congenital heart disease

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes for this disorder is having only one functional copy of the gene TBX5, instead of two healthy copies, inherited from parents.

Researchers link genome folding to gene activity and brain tissue organization in Alzheimer's

Researchers from Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington shed new light on Alzheimer's disease that could point to new directions for treatment.

Chemotherapy leaves early genomic fingerprints in childhood tumors

Nearly half of childhood tumors treated with common types of chemotherapy showed detectable DNA changes linked to treatment within 18 months, according to a new international study led by The Hospital for Sick Children (SickKids).

RNA-based testing can improve detection of key lung cancer biomarkers

New research has shown that RNA-based testing can improve the detection and interpretation of clinically actionable genomic alterations leading to MET exon 14 skipping in lung cancer patients—important biomarkers that may be missed by DNA-only approaches.
