  • Mitochondria are the 'canary in the coal mine' for cellular stress December 14, 2019
    Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, researchers have discovered a new function of mitochondria: they set off molecular alarms when cells are exposed to stress or chemicals that can damage DNA, such as chemotherapy. The results could lead to new cancer treatments that prevent tumors from b […]
  • Standard pathology tests outperform molecular subtyping in bladder cancer December 13, 2019
    While trying to develop a comparatively easy, inexpensive way to give physicians and their patients with bladder cancer a better idea of likely outcome and best treatment options, scientists found that sophisticated new subtyping techniques designed to do this provide no better information than long-standing pathology tests.
  • Deadly 'superbugs' destroyed by molecular drills December 12, 2019
    Motorized molecules activated by light target and drill through highly antibiotic resistant bacteria and kill them within minutes. The molecules can open bacteria to attack by drugs they previously resisted. The strategy could be applied to bacterial infections or diseases on the skin, in the lungs or in the gastrointestinal tract.
  • Breast cancer cells swallow a 'free lunch' of dietary fat particles from the bloodstream December 12, 2019
    A research team has previously shown that fatty particles from the bloodstream may boost the growth of breast cancer cells. They now show that through an unexpected mechanism not previously described in cancer cells, the fat particles bind to the breast cancer cell surface and are then taken into the cell, providing a large supply of fuel that drives prolife […]
  • Chemists' calculations may advance cancer prediction December 12, 2019
    A computational study by chemists showed the dynamics of tumor formation don't necessarily correlate with clinical data on lifetime cancer risks. It suggests biomarkers may someday be able to help predict when mutations in cells will turn cancer-prone cells into full-blown cancer.
  • Metabolic adaptation ensures survival of colon cancer cells December 12, 2019
    Colon cancer cells deficient in p53, one of the most important control proteins in cell growth, activate a particular metabolic pathway to adapt to the lack of oxygen and nutrients inside the tumor. Statins, which are often prescribed to lower cholesterol, block this metabolic pathway and cause the cancer cells to die, as scientists have now discovered. The […]
  • Virus multiplication in 3D December 12, 2019
    Vaccinia viruses serve as a vaccine against human smallpox and as the basis of new cancer therapies. Two studies now provide fascinating insights into their unusual propagation strategy at the atomic level.
