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).

Unraveling the mystery of drug-induced liver injury

DILI is broadly categorized into intrinsic and idiosyncratic types. Intrinsic hepatotoxins, such as APAP, cause dose-dependent injury, while idiosyncratic DILI involves complex immune and metabolic interactions that remain poorly understood.

A genetic variant modulates interferon signaling and disease risk

For years, scientists have looked to a critical piece of immune system machinery - known as the interferon pathway - for answers. There, when our cells sense an infection, they release a protein known as interferon, which warns other cells to fight the virus.

Deep learning transforms PDAC diagnosis and treatment

Researchers have successfully developed a deep learning model that classifies pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer, into molecular subtypes using histopathology images.

Circadian chaos: How transportation noise harms heart health

Transportation noise poses serious risks to cardiovascular health, causing inflammation, oxidative stress, and circadian rhythm disruption, with compounded effects from air pollution.

New study challenges traditional view of how the genetic code evolved

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.

NIH funding supports innovative lupus research using DNA mimic molecules

Lupus causes chronic pain, fatigue, and potentially organ damage for 1.5 million Americans and is a challenge for researchers trying to find better treatments.

Surrey research offers new hope for people suffering from immunodeficiencies

Several rare immune disorders are caused by mutations in the patient's DNA. The University of Surrey and its collaborators found that targeting the mutated pathways with new drugs offers new hope for people suffering from rare conditions such as immunodeficiencies.

Study pinpoints how a network of different proteins controls rest and activation

Cells in the immune system don't always fight; they often rest and wait for threats, like viruses or bacteria.

Next-generation cell-penetrating antibodies could transform cancer treatment

A news feature on the research paper "Next-generation cell-penetrating antibodies for tumor targeting and RAD51 inhibition" by Rackear et al. was published in Oncotarget's Volume 15 on November 22, 2024, titled "Advancements in cell-penetrating monoclonal antibody treatment."

Early exposure to parental smoking linked to higher MS risk

Cutting early life exposure to parental smoking may lower the risk of developing MS (multiple sclerosis) in those who are genetically predisposed to the disease, finds research published online in the Journal of Neurology Neurosurgery & Psychiatry.

Accelerated aging linked to early-onset colorectal cancer, study shows

New research from Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine suggests that one's biological age, which can be higher than his or her chronological age – a concept called accelerated aging – may predict who's at risk for developing colon polyps, a known risk factor for colorectal cancer.
