Salk Institute and Dana Farber Cancer Institute researchers contribute to production of largest-ever map of plant protein interactionsScience usually progresses in small steps, but on rare occasions, a new combination of research expertise and cutting-edge technology produces a 'great leap forward.' An international team of scientists, whose senior investigators include Salk Institute plant biologist Joseph Ecker, report one such leap in the July 29, 2011 issue of Science. They describe their...

If one is good, two can sometimes be better. Researchers at the California Institute of Technology (Caltech) have certainly found this to be the case when it comes to a small HIV-fighting protein.The protein, called cyanovirin-N (CV-N), is produced by a type of blue-green algae and has gained attention for its ability to ward off several diseases caused by viruses, including HIV and influenza. Now Caltech researchers have found that a relatively simple engineering technique can boost the...

Every year, plant diseases wipe out millions of tons of crops, lead to the waste of valuable water resources and cause farmers to spend tens of billions of dollars battling them.Now a new discovery from a University of North Carolina at Chapel Hill-led research team may help tip the war between plants and pathogens in favor of flora.The finding "“ published in the July 29, 2011, issue of the journal Science "“ suggests that while pathogens employ a diverse arsenal of weapons, they use...

Researchers at Albert Einstein College of Medicine of Yeshiva University have developed the first fluorescent protein that enables scientists to clearly "see" the internal organs of living animals without the need for a scalpel or imaging techniques that can have side effects or increase radiation exposure.The new probe could prove to be a breakthrough in whole-body imaging "“ allowing doctors, for example, to noninvasively monitor the growth of tumors in order to assess the...

SANTA CLARA, Calif., July 18, 2011 /PRNewswire/ -- Cell Biosciences, Inc. today announced that it has changed its name to ProteinSimple to clearly reflect the Company's core mission in protein research. The Company's goal is simply to help researchers gain a better understanding of proteins and their role in disease. ProteinSimple's strategy is to power protein research by making it simpler and more quantitative, ultimately revealing new insights into the true nature of proteins. Over the...

Over 1.5 million measurements of protein expression and phosphorylation now available at new KiNET-Antibody Microarray website VANCOUVER, July 13, 2011 /PRNewswire/ - Kinexus Bioinformatics Corporation, a world-leader in molecular intelligence research, announced a major expansion in its KiNET DataBank (http://www.kinexus.ca/ourServices/kinet/kinet.html) for the study of cell communication systems with the launch of the KiNET-Antibody Microarray (KiNET-AM) website. This open...

New information from fission yeast provides clues for research on cancer treatments When a cell divides, the genetic information in the chromosomes must be passed on error-free to the daughter cells. Researchers at the Friedrich Miescher Laboratory in Tübingen are studying this process using fission yeast as a model organism. In cooperation with researchers at the University of Tübingen, they succeeded in attributing additional tasks to the Aurora enzymes, which were already recognized...

A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer's disease and prevent the sexual transmission of HIV.The researchers report that they have designed molecular inhibitors that target specific proteins associated with Alzheimer's disease and HIV to prevent them from forming amyloid fibers, the elongated chains of interlocking proteins that play a key role in more than two dozen degenerative and often fatal...

Imagine dropping dish soap into a sink full of greasy water. What happens? As soon as the soap hits the water, the grease recoils"”and retreats to the edges of the sink.Now, what if the sink was a cancer cell, the globs of grease were cancer-promoting proteins and the dish soap was a potential drug? According to new research from the University of Toronto Mississauga, such a drug could force the proteins to the cell's membrane (a.k.a., the edge of the sink)"”and make the cancer cell more...

Engineering researchers at Rensselaer Polytechnic Institute have developed new process for the microdissection and in-depth biochemical analysis of bone tissue A new technique developed at Rensselaer Polytechnic Institute allows researchers to collect large amounts of biochemical information from nanoscale bone samples.Along with adding important new insights into the fight against osteoporosis, this innovation opens up an entirely new proteomics-based approach to analyzing bone quality. It...
