Zack's research examined how a type of stress protein involved in preventing diseases as diverse as lens cataract, cancer and Alzheimer's disease are produced. Zack used the model fish species the zebrafish to examine how regions of DNA that switch on the production of these stress proteins work. The image below shows a 3-day old zebrafish that is glowing green wherever one of these DNA switches is active. This image was part of a poster presentation given by Dr. Posner at the 2013 meeting of the Association for Research in Vision and Ophthalmology last month in Seattle, Washington.
