Stemlike cells at tumor perimeter promote new blood vessels to feed tumor growth

Cancerous tumors need nutrients to grow, so they secrete factors promoting new blood-vessel formation to feed themselves. Researchers have long known that cells in low-oxygen environments at the center of the tumor send out these factors, but a new study by University of Illinois researchers found that stemlike cells at […]

New study shows how cells can be led down non-cancer path

As cells with a propensity for cancer break down food for energy, they reach a fork in the road: They can either continue energy production as healthy cells, or shift to the energy production profile of cancer cells. In a new study published Monday (Oct. 23, 2017) in the journal Nature […]

Major study of genetics of breast cancer provides clues to mechanisms behind the disease

Seventy-two new genetic variants that contribute to the risk of developing breast cancer have been identified by a major international collaboration involving hundreds of researchers worldwide. Of these variants, reported today in the journals Nature and Nature Genetics, 65 are common variants that predispose to breast cancer and a further seven predispose specifically […]

Inflammation trains the skin to heal faster

Scars may fade, but the skin remembers. New research from The Rockefeller University reveals that wounds or other harmful, inflammation-provoking experiences impart long-lasting memories to stem cells residing in the skin, teaching them to heal subsequent injuries faster. These stem cells, which replenish the skin’s outer layer take their cue […]

Researchers ‘drug the undruggable’ through unique collaboration

A new study published in Nature, conducted by an alliance between industry and academia involving the University of Liverpool, highlights a new approach to targeting key cancer-linked proteins, thought to be ‘undruggable’. The majority of cancers have a faulty or inactive gene, p53, which allows them grow out of control. The […]
