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 discovery offers clues to overcoming resistance to cancer therapies

Cancer cells proliferate despite a myriad of stresses-;from oxygen deprivation to chemotherapy-;that would kill any ordinary cell.

Will ‘Dr. Disinformation’ ever face the music?

Earlier this month, Dr. Rashid Buttar posted on Twitter that covid-19 "was a planned operation" and shared an article alleging that most people who got the covid vaccine would be dead by 2025.

Research highlights potentially life-saving screening for HR-HPV–driven head and neck cancers

Cancer causing high-risk human papillomaviruses (HR-HPV) are responsible for the rising incidence of HR-HPV–driven head and neck cancers (HNC), particularly oropharyngeal cancers (OPC, or throat cancers). Investigators have determined that HR-HPV DNA can be detected in saliva in most patients with HPV-driven OPC at the time of diagnosis. This work highlights a potentially life-saving screening program based on salivary HR-HPV DNA testing for early cancer detection and patient monitoring. Their findings appear in The Journal of Molecular Diagnostics, published by Elsevier.

Repeated injury to the epithelial tissue of airways causes "biological aging" of stem cells

Are prematurely aged or overworked stem cells a significant factor in chronic lung disease? Findings of a study just released in STEM CELLS Translational Medicine (SCTM) say this is likely so.

Discovery of genes opens the door to new treatments for obesity

Promising news in the effort to develop drugs to treat obesity: University of Virginia scientists have identified 14 genes that can cause and three that can prevent weight gain.

Scientists use statistical mechanics to make sense of DNA folding

At more than 2 meters long, the human DNA molecule uses intricate folding patterns to fit into cells while locally unfolding to express genes. Such phenomena, however, are difficult to measure in experiments, and theoretical frameworks explaining them continue to be at odds with one another.

Comparison of recombinant SARS-CoV-2 receptor binding domain produced in mammalian, insect, and bacterial cells

In a recent study, RBD produced in various cell types are characterized in-depth, comparing their applicability for future COVID-19 research.

KU researcher wins $1.25 million award to investigate the vital role of sex hormones in tissue repair

Our ability to heal and regenerate new tissue after an injury has much to do with biological sex. For instance, following menopause, the loss of sex-hormone signaling in women can lead to degenerative diseases such as osteoporosis and osteoarthritis, where bone and cartilage degrade and become more delicate and brittle because of tissue loss.
