Researchers develop multiplexed screening approach to study cancer development in mice

In a novel use of the CRISPR/Cas9 system, which can be deployed to switch genes off, researchers from Germany, the UK and Spain have developed a multiplexed screening approach to study and model cancer development in mice. The scientists mutated genes in the adult mouse liver uncovering their cancer-causing roles and determining which combinations of genes cooperate to cause liver cancer.

UCSF researchers map genetic signature of unusual stem cells in the human brain

The human cerebral cortex contains 16 billion neurons, wired together into arcane, layered circuits responsible for everything from our ability to walk and talk to our sense of nostalgia and drive to dream of the future. In the course of human evolution, the cortex has expanded as much as 1,000-fold, but how this occurred is still a mystery to scientists.

UVA researchers identify new strategy for attacking cancer cells

University of Virginia School of Medicine researchers have discovered a new strategy for attacking cancer cells that could fundamentally alter the way doctors treat and prevent the deadly disease. By more selectively targeting cancer cells, this method offers a strategy to reduce the length of and physical toll associated with current treatments.

Johns Hopkins scientists develop novel fish embryo technique to identify potential new treatments for diabetes

In experiments with 500,000 genetically engineered zebrafish embryos, Johns Hopkins scientists report they have developed a potentially better and more accurate way to screen for useful drugs, and they have used it to identify 24 drug candidates that increase the number of insulin-producing cells in the pancreas.

Gene responsible for cancer growth plays unexpected role in prostate cancer

A gene that is responsible for cancer growth plays a totally unexpected role in prostate cancer. The gene Stat3 is controlled by the immune modulator interleukin 6 and normally supports the growth of cancer cells. The international research team led by Prof. Lukas Kenner from the Medical University of Vienna, the Veterinary University of Vienna, and the Ludwig Boltzmann Institiute for Cancer Research (LBI-CR) discovered a missing link for an essential role of Stat3 and IL-6 signalling in prostate cancer progression.

Study on fruit flies, brewer's yeast may provide clues about cause of Spinal Muscular Atrophy

Scientists at the University of Malta and the Institut de Génétique Moléculaire de Montpellier (CNRS/Université de Montpellier) have shown that fruit flies and brewer's yeast can reveal clues about the cause of Spinal Muscular Atrophy (SMA), the most common genetic killer of infants.

Johns Hopkins researchers identify new therapy to treat lung cancer

A multidisciplinary team led by Johns Hopkins researcher Venu Raman, Ph.D., with notable contributions from Guus Bol, Farhad Vesuna and Phuoc Tran of Johns Hopkins, has identified a new therapy for lung cancer, the most common cancer worldwide. The therapy has been in development for six years and involves a first-in-class molecule designed by the team.

Growth of neuronal and vascular networks is controlled by same signaling molecules

Neurons and blood vessels often traverse the body side by side, a fact observed as early as the 16th century by the Flemish anatomist Andreas Vesalius. Only over the last ten years, however, researchers have discovered that the growth of neuronal and vascular networks is controlled by the same molecules.

MDC scientists find solution to increase efficiency of precise genetic modifications

CRISPR-Cas9 is a powerful new tool for editing the genome. For researchers around the world, the CRISPR-Cas9 technique is an exciting innovation because it is faster and cheaper than previous methods. Now, using a molecular trick, Dr. Van Trung Chu and Professor Klaus Rajewsky of the Max Delbrück Center for Molecular Medicine Berlin-Buch and Dr. Ralf Kühn, MDC and Berlin Institute of Health, have found a solution to considerably increase the efficiency of precise genetic modifications by up to eightfold.

Worst effects of reperfusion injury after heart attack may be prevented with iodide

Blocked arteries are typically the trigger, stopping the flow of blood and starving the heart muscle of oxygen. But when the blockage is removed and the blood comes rushing back, it wreaks havoc of its own. The result is called reperfusion injury, a life-threatening flood of inflammation and cellular destruction that has stumped scientists for 40 years.
