Caspase-3 Cleaves in Unforeseen Ways Investigators at Burnham Institute for Medical Research (Burnham) have identified novel cleavage sites for the enzyme caspase-3 (an enzyme that proteolytically cleaves target proteins). Using an advanced proteomic technique called N-terminomics, Guy Salvesen, Ph.D., professor and director of the Apoptosis and Cell Death Research program of Burnham's NCI-designated Cancer Center, and colleagues determined the cleavage sites on target proteins and found,...

Comprehensive understanding of bacteria could lead to new insights into many organisms Investigators at Burnham Institute for Medical Research (Burnham), University of California, San Diego (UC San Diego), The Scripps Research Institute (TSRI), Genomics Institute of the Novartis Research Foundation (GNF) and other institutions have constructed a complete model, including three dimensional protein structures, of the central metabolic network of the bacterium Thermotoga maritima (T. maritima)....

Researchers at the Burnham Institute for Medical Research (Burnham) have discovered that reactive oxygen species, such as superoxide and hydrogen peroxide, play a key role in forming invadopodia, cellular protrusions implicated in cancer cell migration and tumor metastasis. Sara Courtneidge, Ph.D., professor and director of the Tumor Microenvironment Program at Burnham's NCI-designated Cancer Center, and colleagues have found that inhibiting reactive oxygen reduces invadopodia formation and...

Investigators at Burnham Institute for Medical Research (Burnham) have found that the conserved protein d4eBP modulates cardiac aging in Drosophila (fruit flies). The team also found that d4eBP, which binds to the protein dEif4e, protects heart function against aging. This research enhances our understanding of the TOR and FoxO signaling pathways and provides a more specific target for further research into cardiac aging. Since the TOR and FoxO genes are conserved between Drosophila and...

Competition Between Proteins Maintains Cellular Balance Dieter Wolf, M.D., and colleagues at Burnham Institute for Medical Research (Burnham) have illuminated how competition between proteins enhances combinatorial diversity during ubiquitination (the process that marks proteins for destruction). Using S. pombe fission yeast as a model, the Wolf laboratory uncovered an intricate relationship, in which an array of Fbox proteins alternately attach to and are kicked off of a cullin-RING...

 Researchers at Burnham Institute for Medical Research (Burnham), University of Texas Southwestern Medical Center and University of Maryland have demonstrated that an enzyme that is essential to many bacteria can be targeted to kill dangerous pathogens. In addition, investigators discovered chemical compounds that can inhibit this enzyme and suppress the growth of pathogenic bacteria. These findings are essential to develop new broad-spectrum antibacterial agents to overcome multidrug...

Scientists at UC Santa Barbara have discovered a potential new drug delivery system. The finding is a biological mechanism for delivery of nanoparticles into tissue. The results are published in this week's Proceedings of the National Academy of Sciences."This work is important because when giving a drug to a patient, it circulates in the blood stream, but often doesn't get into the tissue," said senior author Erkki Ruoslahti, of the Burnham Institute for Medical Research at UCSB. "This is...

The partnership will bridge diabetes and obesity research and treatment ORLANDO, Fla., Aug. 17 /PRNewswire-USNewswire/ -- Florida Hospital and Burnham Institute for Medical Research at Lake Nona have taken another giant step in advancing Orlando as a hub for medical research. Today, officials from Florida Hospital and Burnham Institute came together to announce the appointment of Dr. Steven R. Smith, an internationally-renowned diabetes and obesity researcher, as the new executive director...

Investigators at Burnham Institute for Medical Research (Burnham) and the University of Connecticut Health Center (U.C.H.C.) have gained new understanding of the role hyaluronic acid (HA) plays in skeletal growth, chondrocyte maturation and joint formation in developing limbs. Significantly, these discoveries were made using a novel mouse model in which the production of HA is blocked in a tissue-specific manner. The Yamaguchi laboratory genetically modified the Has2 gene, which is a critical...

Scientists at Burnham Institute for Medical Research (Burnham) have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. The study was published in the journal Cancer Research on June 15.The team of scientists, led by Kristiina Vuori, M.D., Ph.D., professor and director of the Cancer Center at Burnham, showed that Caspase-8 caused...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
