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).

New study seeks to understand how colibactin causes cancer

For more than a decade, scientists have worked to understand the connection between colibactin, a compound produced by certain strains of E. coli, and colorectal cancer, but have been hampered by their inability to isolate the compound.

WVU gynecologic oncologist investigates novel treatment for cervical and vaginal cancers

Cervical cancer can be insidious. Changes to the cervix are often detected with a pap smear, but for those with limited access to health care, cervical and vaginal cancers can go unnoticed for years--silently growing, spreading and invading other organs--and by the time they're detected, they may be so advanced that the patient's prognosis is poor and her treatment options few.

Blood-based liquid biopsies can accurately track cancer treatment responses

Results of two clinical studies have added to evidence that blood-based liquid biopsies can accurately track lung cancer treatment responses by measuring circulating tumor DNA (ctDNA) during immunotherapy and related treatments.

Whole-genome sequencing and sharing real-time data could limit spread of foodborne bacteria

Employing advanced genetic-tracing techniques and sharing the data produced in real time could limit the spread of bacteria -- Bacillus cereus -- which cause foodborne illness, according to researchers who implemented whole-genome sequencing of a pathogen-outbreak investigation.

Novel approach uses small amounts of tissue to quantify PD-L1 expression levels in tumors

Immune checkpoint inhibitors, such as the anti-PD-1 antibody pembrolizumab, have become important tools for managing non-small-cell lung cancer.

Study discovers new therapy for aggressive blood cancer

Acute myeloid leukemia is the most common form of acute leukemia. It is characterized by an increase of malignant myeloid progenitor cells at the expense of mature blood cells.

Mountain chickadee research shows link between natural selection and spatial memory

Chickadees with better learning and memory skills, needed to find numerous food caches, are more likely to survive their first winter, a long-term study of mountain chickadees has found.

New study provides insights into developmental organization of the brain

What makes us human, and where does this mysterious property of "humanness" come from? Humans are genetically similar to chimpanzees and bonobos, yet there exist obvious behavioral and cognitive differences.

Microbiologists identify enzyme that makes Helicobacter so adaptable

The bacterial pathogen Helicobacter pylori owes its worldwide distribution to its genetic adaptability. Ludwig-Maximilians-Universitaet Munich microbiologists have identified an enzyme that plays a vital role in the flexible control of global gene expression in the species.

New DNA methylation GrimAge tool allows you to predict lifespan and healthspan

The Grim Reaper arrives for each of us eventually--wouldn't it be nice to know when? Now UCLA researchers have developed a new tool to help you plan ahead for your date with the Angel of Death.

Low physical fitness during adolescence associated with later receipt of disability pension

Obesity or low physical fitness during adolescence is strongly associated with disability pension later in life. This is shown in a study of more than one million Swedish men, published in Annals of Internal Medicine by researchers at Karolinska Institutet.
