Technique able to analyze conformations of complex molecular machines
Mar 17, 2014
Open, feed, cut. Such is the humdrum life of a motor molecule, the subject of new research at Rice University, that eats and excretes damaged proteins and turns them into harmless peptides for disposal.The why is obvious: Without these trash bins, the Escherichia coli bacteria they serve would die. And thanks to Rice, the how is becoming clearer. Read More
E. coli coaxed to resist radiation damage In the lab
Mar 17, 2014
Capitalizing on the ability of an organism to evolve in response to punishment from a hostile environment, scientists have coaxed the model bacterium Escherichia coli to dramatically resist ionizing radiation and, in the process, reveal the genetic mechanisms that make the feat possible. Read More
Researchers reveal mathematical and biochemical 'design features' for cell decoding of pulses
Mar 17, 2014
Every cell in the body has to sense and respond to chemicals such as hormones and neurotransmitters. They do so by relaying information from receptors to intracellular biochemical pathways that control cell behaviour, but relatively little is known about how cells decode the information in dynamic stimuli.

Surprising role played by 'velcro protein' in cell migration
Mar 17, 2014
Studying epithelial cells, the cell type that most commonly turns cancerous, Johns Hopkins researchers have identified a protein that causes cells to release from their neighbors and migrate away from healthy mammary, or breast, tissue in mice. They also found that deletion of a cellular "Velcro protein" does not cause the single-celled migration expected. Read More
New ovarian cancer targets proposed
Mar 17, 2014
Proteins called TAFs were once thought to be generic cogs in the machinery of gene expression, but in a new study Brown University scientists propose that they may be important suspects in the progression of ovarian cancer that should not continue to be overlooked. Read More
Insulin-treated diabetes increases mortality four-fold in cancer patients
Mar 17, 2014
People who have diabetes at the time they are diagnosed with cancer are more likely to die early than those without diabetes, concludes research published in Diabetologia (the journal of the European Association for the Study of Diabetes). The research is by Kristina Ranc, University of Copenhagen and Steno Diabetes Center, Gentofte, Denmark, and colleagues. Read More
Biologists get a new view of tumors' evolution
Mar 17, 2014
Cancer cells undergo extensive genetic alterations as they grow and spread through the body. Some of these mutations, known as "drivers," help spur cells to grow out of control, while others ("passengers") are merely along for the ride. Read More
Mouse model created to act as biosensor
Mar 17, 2014
Scientists from the UK and Australia have created a mouse that expresses a fluorescing 'biosensor' in every cell of its body, allowing diseased cells and drugs to be tracked and evaluated in real time and in three dimensions.This biosensor mimics the action of a target molecule, in this case a protein known as 'Rac', which drives cell movement in many types of cancer.

Mood, sleep and quality of life improved by mindfulness-based meditation in teenagers with cancer
Mar 16, 2014
Mindfulness-based meditation could lessen some symptoms associated with cancer in teens, according to the results of a clinical trial intervention led by researchers at the University of Montreal and its affiliated CHU Sainte-Justine children's hospital. Mindfulness-based meditation focuses on the present moment and the connection between the mind and body. Read More
Cryoablation and nanoparticle-encapsulated anticancer drug combined to destroy cancer stem-like cells
Mar 16, 2014
Combining nanodrug-based chemotherapy and cryoablation provides an effective strategy to eliminate cancer stem-like cells (CSCs) the root of cancer resistance and metastasis, which will help to improve the safety and efficacy of treating malignancies that are refractory to conventional therapies.
