A new way to share models of biological systems

...o identify precisely the components of models, and helps them to retrieve appropriate models, which they can then visualize and build upon using any SBML-compatible software. "Ultimately," says Le Novère, "we hope that publishers will encourage any author who plans to publish a new model to submit it to t...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

... bacterium Escherichia coli promotes mutations and helps the pathogen evolve resistance to antibiotics. The scientists also show that E. coli evolution could be halted in its tracks by subjecting the bacteria to compounds that block LexA. Interfering with this protein renders the bacteria unable to evolve ...

Newly Discovered 'Branding' Process Helps Immune System Cells Pick Their Fights

...une system cells known as antigen-presenting cells helps T cells determine what to attack. They do this by displaying fragments of proteins they have picked up on their surfaces for inspection by T cells. Fragments of proteins are called peptides. Researchers also knew that when antigen-presenting cells a...

Future diabetes drugs may target new protein interaction

...t at this point, knowing for sure whether sirtuin1 helps extend lifespan (an organism issue) or is merely involved in cellular aging (a cell-by-cell issue) in mammals will take much more work. Sirtuin1's potential as a target for treating diabetes is much closer, says Puigserver. The researchers are now p...

While on trail of dioxin, scientists pinpoint cancer target of green tea

...eam found that EGCG binds to HSP90, a protein that helps other proteins stay stable, serving the same role as a tail on a kite. When the two bind, HSP90 no longer turns on the AH receptor, stopping the cascade of events that would lead to the activation of several harmful genes. This weekend Palermo is re...

Chemists synthesize molecule that helps body battle cancers, malaria

...s of QS-21A, a medicinally important molecule that helps the body battle disease, has been achieved by chemists at the University of Illinois at Urbana-Champaign. In clinical trials, QS-21A has been shown to significantly improve the body's immune response in vaccine therapies against aggressive diseases ...

Pair of cancer genes found to drive both cell migration and division

...n tandem to regulate a molecule called PIP3, which helps the cell decide where to push outward - PI3K makes PIP3 on the membrane on one side of a cell while PTEN breaks it down on the other side. But when both enzymes are missing, levels of PIP3 remain constant throughout the membrane, and the cell can't m...

Newly discovered protein an important tool for sleeping sickness research

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...ses to inject its toxins. LcrV plays two roles. It helps the needle to penetrate the membrane surrounding the target cell. It also suppresses the immune response. LcrV causes affected cells to release 40 times the normal levels of interleukin 10 (IL-10), which dampens down the immune response. LcrV also pr...
