Mice show the way to improved stem cell therapy for heart attacks

When the results of clinical trials do not live up to expectations from pre-clinical studies in animals it can be all too easy to ascribe the divergence to species differences, however scientists are increasingly aware that in many, even most cases, the problem may not be species differences but rather differences in the design of studies in … Continue reading Mice show the way to improved stem cell therapy for heart attacks

Lighting the Way to New Treatments

A variety of diseases in humans happen when proteins with important cellular functions are lacking or are produced in abnormally low amounts. One example is type-2 diabetes mellitus which is caused by a complex set of problems involving the use of sugars (mostly, glucose) as an energy source. After eating, sugars in food are taken … Continue reading Lighting the Way to New Treatments

Have No Fear, Mice Are Here

RNAi: Send in the Nanobots!

The publication of the preliminary results of a small clinical trial of a new therapy called RNA interference (RNAi) online in the scientific journal Nature is causing quite a stir in the scientific community this week.  A team led by Professor Mark E. Davis at Caltech targeted the delivery of a nanoparticle only 70 nanometers … Continue reading RNAi: Send in the Nanobots!
