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).

Blood clot discovery could lead to development of better treatments for blood diseases

Scientists have discovered new ways in which the body regulates blood clots, in a discovery which could one day lead to the development of better treatments that could help prevent and treat conditions including heart diseases, stroke and vascular dementia.

Vapers develop cancer-related gene deregulation as cigarette smokers

If you think vaping is benign, think again. A small USC study shows that e-cig users develop some of the same cancer-related molecular changes in oral tissue as cigarette smokers, adding to the growing concern that e-cigs aren't a harmless alternative to smoking.

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.

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.
