Rockefeller Researchers Produce 3-D Picture of DNA-reading Molecular Machine
Researchers at The Rockefeller University have determined the first three-dimensional structure of the cellular RNA polymerase (RNAP), a molecular machine that activates individual genes by transcribing, or reading out, the instructions encoded in their DNA. The structure, published in the Sept. ...
Researchers Propose New Theory to Explain How Visual Pigments are "Tuned"
Scientists from the Howard Hughes Medical Institute (HHMI) at The Rockefeller University and from the University of California-Berkeley have proposed a new theory on how the human eye perceives colors. Using techniques of molecular biology and spectroscopy, the research, reported in the August is...
Rockefeller University Luncheon Honors Science Outreach Program, Promotes Siemens Westinghouse Competition
The Rockefeller University and the Siemens Foundation will sponsor a luncheon on Wednesday, August 18, to honor Rockefeller’s Science Outreach Program for high school students and teachers and to promote the Siemens Westinghouse Science and Technology Competition. Sponsored by The Siemens Founda...
Rockefeller Scientists Discover a Surprising New Cancer Gene
Scientists at The Rockefeller University have found, for the first time, that the persistent activation of a protein called Stat3 can, by itself, cause normal cells to behave like cancer cells. The research, reported in the August 6 issue of Cell, provides both a scientific surprise and a promisi...
Rockefeller Researchers Inject Cells, Boost Immune System in Humans
Findings take important first step toward vaccines for cancer, viruses A single injection of specialized immune system cells–removed from the bloodstream and exposed to a foreign substance–can trigger a potent immune response in humans that lasts for months, Rockefeller University researchers r...
Rockefeller and Michigan State Scientists Identify Dangers of Tamoxifen and Recommend Simple Corrective Measures
Researchers Urge Cautious Approach for Healthy Women Considering Tamoxifen A team of researchers at The Rockefeller University and Michigan State University has identified a biochemical mechanism that may cause the potentially life-threatening side-effects associated with use of the anti-breast c...
Rockefeller University Researchers Find Large Hole-Forming Protein in Bacteria -- A Potential Achilles' Heel?
Finding Opens Door on Dysentery, Bubonic Plague, Cholera and Salmonella Poisoning Researchers at The Rockefeller University have shown for the first time that a protein called pIV forms a hole in the outer membrane of the bacterium E. coli to allow passage of large molecules. The finding, reporte...
Rockefeller University Scientists Receive Prestigious Awards for Cancer Research
General Motors Recognizes World's Foremost Cancer Scientists DETROIT — Arnold J. Levine, Ph.D., newly appointed president of The Rockefeller University, and Robert G. Roeder, Ph.D., professor and head of the Laboratory of Biochemistry and Molecular Biology, have been recognized by the General Mot...
Neurobiologists Show How the Brain Processes Signals from Pheromones
Researchers at The Rockefeller University have shown for the first time in mice how the brain processes signals from pheromones, essential chemicals used by animals to communicate with each other. Reported in the April 16 issue of Cell, the findings provide the first look at the "wiring diagram" ...
Researchers Shed Light on How Cells Commit Suicide
A team of researchers led by Associate Professor David Cowburn, Ph.D., has determined the three-dimensional structure of a molecule that regulates programmed cell death, a critical process important for many diseases, including cancer, heart disease and autoimmunity. The structure, reported in th...
