microRNA shown to reduce lung cancer growth

A small RNA molecule, known as let-7 microRNA (miRNA), substantially reduced cancer growth in multiple mouse models of lung cancer, according to work by researchers at Yale University and Asuragen, Inc., published in the journal Cell Cycle.

New insight into radiation damage to DNA

A new technique for assessing the damage radiation causes to DNA indicates that the spatial arrangement of damaged sites, or lesions, is more important than the number of lesions in determining the severity of the damage.

New understanding of Norwalk virus

Using the Canadian Light Source synchrotron, an international team led by University of Calgary researcher Ken Ng has determined the detailed structure of the enzyme the Norwalk virus uses to make copies of its genetic code in order to replicate itself.

Discovery alters long standing concept of fixed protein structure

The thousands of proteins found in nature are simply strings of amino acids, assembled by genes, and scientists have long believed that they automatically fold themselves into uniquely fixed, 3-dimensional shapes to fire the engine of life.

Researchers find cause of severe allergic reaction to cetuximab

Clinicians have been perplexed by the fact that some patients given the drug cetuximab - an immune-based therapy commonly used to treat persons diagnosed with head and neck cancer, or colon cancer - have a severe and rapid adverse reaction to the drug.
