Oregon Health & Science University researchers have figured out how to turn a mouse into a factory for human liver cells that can be used to test how pharmaceuticals are metabolized.The technique, published in the journal Nature Biotechnology, could soon become the gold standard not only for examining drug metabolism in the liver, which helps scientists determine a drug’s toxicity.

MIT researchers have developed a new way to study the function of microRNA, tiny strands of genetic material that help regulate at least 25 percent of a cell’s genes. The new technique could shed light on microRNA’s hypothesized role in tumor development. Malfunctions in microRNA have been linked with cancer, but very few direct relationships have been established between specific microRNAs and the genes they regulate. [click link for full article]

Bones are typically thought of as calcified, inert structures, but researchers at Columbia University Medical Center have now identified a surprising and critically important novel function of the skeleton. They’ve shown for the first time that the skeleton is an endocrine organ that helps control our sugar metabolism and weight and, as such, is a major determinant of the development of type 2 diabetes.
