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…)
Early Step toward Treatment for Diseases that Affect Blood Flow
University of Utah bioengineers showed that tiny blood vessels grow better in the laboratory if the tissue surrounding them is less dense. Then the researchers created a computer simulation to predict such growth accurately – an early step toward treatments to provide blood supply to tissues damaged by diabetes and heart attacks and to skin grafts and implanted ligaments and tendons.
“Better understanding of the processes that regulate the growth of blood vessels puts us in a position ultimately to develop new treatments for diseases related to blood vessel growth,” and to better understand cancer metastasis, says bioengineering professor Jeff Weiss of the university’s Scientific Computing and Imaging Institute.

Researchers have sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single cell, a long-anticipated step toward better cancer diagnostics and other medical applications.
Researchers have successfully isolated and sequenced the entire messenger RNA – the “genetic photocopies” – contained in the nucleus of a single brain cell. This research, published in the journal Proceedings of the National Academy of Sciences, will help researchers better understand how organs function in health and disease and provide another stepping stone toward personalized medicine.

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…)
