Shu awarded funding for infrared fluorescent protein research
By David Jacobson / Wed Aug 31, 2011
Xiaokun Shu, PhD, a faculty member in the UCSF School of Pharmacy, has been awarded $165,000 in first-year funding under the UCSF Program for Breakthrough Biomedical Research (PBBR) effective October 1, 2011.
The PBBR, which receives its primary support from the Sandler Foundation, focuses on potentially high impact projects “that are substantially more creative or risky than projects supported by the NIH and other traditional funding sources.”
Shu earned the funding award under the program’s Technologies, Methodologies and Cores category for his proposal: “Design and engineering of long-wavelength highly fluorescent proteins for whole animal imaging.”
The fluorescent labeling of proteins inside cells, to track their movements, interactions and transformations, has been a Nobel-recognized boon to studying biological systems. But until recently the technique was limited in vitro (i.e. petri dish) cell studies.
In 2009, as a post-doctoral researcher in the lab of Nobel Laureate Roger Tsien at UCSD, Shu lead a team that engineered fluorescent proteins designed to be activated by deep red light and emit near-infrared light.
Because of their long wavelengths, those types of light readily penetrate body tissues allowing in vivo imaging of proteins in cells and tissues of living lab animals. Initially, such infrared-fluorescent proteins would be applicable to whole-body imaging to study cancer and stem cell biology.
Shu, who joined the School’s Department of Pharmaceutical chemistry last September, will use the potentially two-year PBBR support to develop infrared fluorescent proteinshundreds of times brighter than the initial ones.
About the School: The UCSF School of Pharmacy is a premier graduate-level academic organization dedicated to improving health through precise therapeutics. It succeeds through innovative research, by educating PharmD health professional and PhD science students, and by caring for the therapeutics needs of patients while exploring innovative new models of patient care. The School was founded in 1872 as the first pharmacy school in the American West. It is an integral part of UC San Francisco, a leading university dedicated to promoting health worldwide.
