Technique developed at the University of Michigan provides a noninvasive alternative to surgery, chemotherapy and radiation treatments for cancer
The U.S. Food and Drug Administration has approved the use of sound waves to break down tumors—a technique called histotripsy—in humans for liver treatment. (more…)
When paleontologists at the University of Washington cut into the fossilized jaw of a distant mammal relative, they got more than they bargained for — more teeth, to be specific. (more…)
In a major breakthrough for ovarian and uterine cancers, Yale researchers have defined the genetic landscape of rare, highly aggressive tumors called carcinosarcomas (CSs), pointing the way to possible new treatments. (more…)
Freiburger Forscher entschlüsseln Mechanismen, mit denen Tumore bei Stress ihr eigenes Wachstum fördern
Ein Enzym, das Tumorwachstum fördert, sammelt sich in gestressten Krebszellen verstärkt an. Das hat die Gruppe des Freiburger Molekularmediziners Prof. Dr. Thomas Reinheckel zusammen mit der Freiburger Biochemikerin Prof. Dr. Sabine Rospert sowie mit Prof. Dr. Elmar Stickeler und Dr. Peter Bronsert vom Universitätsklinikum Freiburg herausgefunden. Das Team hat die Forschungsergebnisse in der Fachzeitschrift „Journal of Biological Chemistry“ veröffentlicht.
Eine Erfindung aus Kassel könnte die Diagnostik von Krebserkrankungen und anderen Leiden vereinfachen, beschleunigen und kostengünstiger und exakter als bisherige Verfahren gestalten. Physiker und Biochemiker der Universität haben dafür eine neuartige Technikplattform entwickelt.
Diese Technikplattform kann mithilfe von „Fängermolekülen“ , einem durch Magnetfelder und magnetisierte kleinste Partikel gesteuerten Reinigungs- und Transportsystem sowie einem Sensor Indikatoren für das Vorhandensein eines bösartigen Tumors aus Blut oder Gewebeschnitten genau analysieren. Darauf haben die Wissenschaftler bereits ein europäisches Patent beantragt. (more…)
New findings show that eating a high-fat diet beginning at puberty speeds up the development of breast cancer and may actually increase the risk of cancer similar to a type often found in younger adult women.
The research comes from the Breast Cancer and the Environment Research Program at Michigan State University and is published in the current online issue of Breast Cancer Research. (more…)
A protein known as Sp2 is key to the proper creation of neurons from stem cells, according to researchers at North Carolina State University. Understanding how this protein works could enable scientists to “program” stem cells for regeneration, which has implications for neural therapies.
Troy Ghashghaei and Jon Horowitz, both faculty in NC State’s Department of Molecular Biomedical Sciences and researchers in the Center for Comparative Medicine and Translational Research, wanted to know more about the function of Sp2, a cell cycle regulator that helps control how cells divide. Previous research from Horowitz had shown that too much Sp2 in skin-producing stem cells resulted in tumors in experimental mice. Excessive amounts of Sp2 prevented the stem cells from creating normal cell “offspring,” or skin cells. Instead, the stem cells just kept producing more stem cells, which led to tumor formation.

ANN ARBOR — Nisin, a common food preservative, may slow or stop squamous cell head and neck cancers, a University of Michigan study found.
What makes this particularly good news is that the Food and Drug Administration and the World Health Organization approved nisin as safe for human consumption decades ago, says Yvonne Kapila, the study’s principal investigator and professor at the University of Michigan School of Dentistry.
