Einstein and Berkeley receive $4.25 million from NIH for next-generation gene imaging
November 2, 2015–(BRONX, NY)–Now that researchers have successfully sequenced the human genome, understanding how those genes operate is one of the next great challenges. To that end, Albert Einstein College of Medicine is taking the lead role in a five-year, $4.25 million grant awarded by the National Institutes of Health (NIH) to develop tools that can image genes and the proteins for which they code.
"Our goal is to develop new instruments to peer into living cells and tissues of animals so that we can visualize cells' innermost workings in real time–particularly the processes by which their genes are regulated," said the principal investigator, Robert Singer, Ph.D., professor and co-chair of anatomy & structural biology, co-director of the Gruss Lipper Biophotonics Center and the Integrated Imaging Program, and the Harold and Muriel Block Chair in Anatomy & Structural Biology at Einstein. "These tools include new and more powerful microscopes and fluorescent probes that emit light when imaged. They will reveal the mechanisms that turn genes on and off, which are ultimately at the crux of life itself and the basis of all diseases." A co-investigator at Einstein, Robert Coleman, Ph.D., is also involved in developing technology for imaging chromatin modifications.
In addition to Einstein, two other institutions are involved in the project: the Janelia Research Campus of the Howard Hughes Medical Institute (HHMI), where Dr. Singer is a senior fellow, and the University of California at Berkeley. HHMI's Transcription Imaging Consortium is coordinating the efforts of the investigators. The Berkeley component of the grant is led by Xavier Darzacq, Ph.D.
Microscopes that will be specifically adapted for conducting research under the grant include the multifocal microscope, the lattice light sheet microscope, the adaptive optics microscope, and the high-speed three-color super registration microscope, all of which were developed at Janelia.
Dr. Singer is a world-renowned expert on mRNA (messenger ribonucleic acid), whose principal role is to carry DNA's instructions from the cell's nucleus to the cytoplasm for protein synthesis. His lab has shown that the dynamics of RNA transcription of a single gene can be observed by live-cell imaging and by multiplexed fluorescent probes (probes of different wavelengths). In addition, Dr. Singer has pioneered rapid and sensitive microscopy that can visualize single RNA molecules in living cells in real time and has devised methods to track RNA molecules through their life cycle.
Recent discoveries from Dr. Singer's lab include pinpointing when and where mRNAs are translated into proteins, using florescent proteins to visualize how memories are formed, and determining the first known mechanism by which cells control the survival of mRNA.
The grant, which was awarded by the National Institute of Biomedical Imaging and Bioengineering, part of the NIH, is titled "Tools for Imaging the Functional Genome in Living Cells and Tissues" (1U01EB021236-01).
About Albert Einstein College of Medicine
Albert Einstein College of Medicine is one of the nation's premier centers for research, medical education and clinical investigation. During the 2013-2014 academic year, Einstein is home to 743 M.D. students, 275 Ph.D. students, 103 students in the combined M.D./Ph.D. program, and 313 postdoctoral research fellows. The College of Medicine has more than 2,000 full-time faculty members located on the main campus and at its clinical affiliates. In 2013, Einstein received more than $150 million in awards from the National Institutes of Health (NIH). This includes the funding of major research centers at Einstein in aging, intellectual development disorders, diabetes, cancer, clinical and translational research, liver disease, and AIDS. Other areas where the College of Medicine is concentrating its efforts include developmental brain research, neuroscience, cardiac disease, and initiatives to reduce and eliminate ethnic and racial health disparities. Its partnership with Montefiore Medical Center, the University Hospital and academic medical center for Einstein, advances clinical and translational research to accelerate the pace at which new discoveries become the treatments and therapies that benefit patients. Through its extensive affiliation network involving Montefiore, Jacobi Medical Center — Einstein's founding hospital, and three other hospital systems in the Bronx, Brooklyn and on Long Island, Einstein runs one of the largest residency and fellowship training programs in the medical and dental professions in the United States.
