Research news from BBSRC

11 October 2005

The following stories appear in the October 2005 edition of Business, the quarterly magazine of research highlights from the Biotechnology and Biological Sciences Research Council (BBSRC).


Controlling 'superpests'
Scientists have developed a new technique that helps make pesticides more effective by removing insects’ ability to exhibit resistance. Their research will extend the effective life of current pesticides, reduce the amount that needs to be sprayed and remove the need for farmers to move to stronger and more harmful chemicals. The new technique relies on applying a chemical to block the insect’s processes that can degrade a pesticide. With the pests newly rendered helpless farmers can apply pesticide to kill them.

Fruit fly studies open new avenue in cancer research
Researchers have discovered a family of amino acid transporters that are powerful growth promoters in fruit flies. When the transporters were overexpressed in a fly, its cells became hypersensitive to insulin-like molecules in the body that have a long-term role in promoting cell growth in development and cancer, and the cells grew excessively. If the equivalent genes in humans have the same effect then this discovery could lead to new drugs or even dietary advice that could block their activity and slow down the growth of tumours.

Gene delivery vehicle for skeletal regeneration
UK scientists are working on new methods to regenerate cartilage and bone by delivering genes to stem cells within the body to instruct them to turn into bone cells. The new research will use tiny nanoscopic systems that cross the surface of a stem cell and then deliver the genes into that prompt the cell to turn into a bone cell. This method of gene delivery could provide significant healthcare benefits as trauma, degenerative disease and bone loss with old age all lead to patients needing orthopaedic procedures that require new bone.

'Ending up' with antibody production
Scientists are pioneering a new technique to produce large numbers of antibodies quickly and reliably and this is being used to help the study of dangerous bacteria. The new technique harnesses the unique properties of the C-terminus of a protein to produce a large number of antibodies that will only bind to a specific protein. The antibodies can then be used to identify, count and track the proteins. Proteins are central to many areas of bioscience research as they are often the targets for vaccines, the raw materials for bioprocessing or are employed as environmental biomarkers. Production of panels of antibodies that previously took years may now be possible in just weeks.

Building proteins on demand
A multidisciplinary team of researchers is developing new tools to direct the evolution of proteins, a move that will help the search for new anti-HIV drugs. The scientists have developed an efficient methodology for generating every possible mutation of a single protein and then assembling this into a library to identify which variations are resistant to drugs and which are not. This information can then be used to develop and validate new drugs.

Bringing physical forces to bear
World-leading laser facilities at the Rutherford Appleton Laboratory in Oxfordshire will be harnessed for biological studies thanks to joint funding from two Research Councils. A new laser system will study the bonds between atoms by looking at the unique frequency of their vibration. The new system will be able to take measurements of these ‘vibrational fingerprints’ at a scale so small that they will by able to study how cells repair damaged DNA, how proteins fold and develop new ways of detecting cancerous and pre-cancerous cells.

‘Model gut’ moves to commercialisation
Researchers at the Institute of Food Research in Norwich are moving closer to turning ten years of research on the workings of the human gut into a computer controlled model that will enable scientists to predict the digestive processes of human gut using real food and medicines. The result will be a revolutionary research tool that will enable researchers to examine the physical, chemical and biochemical functions of the gut as a whole.
