- New insights on a regenerative molecule can help prevent limb amputations in diabetic foot patients
- In England alone, the number of diabetic foot amputations per day is at all time high 20
- The de-oxyribose-1-phosphate can be induced to stimulate skin repair by increasing the vascularization of wounds and non-healing ulcers.
New insights into a molecule could help in treating non-healing wounds and injuries, such as diabetic foot was published in Antioxidants and Redox Signaling journal.
In England, the number of diabetic foot amputations can be considered to be at an all-time high of around 20 amputations per day.
Intense research all around the world is being carried out to discover new treatments that could help avoid such life-changing operations and reduce medical costs for society.
This project funded jointly by the Medical Research Council, and BBSRC (Biotechnology and Biological Sciences Research Council) can help us understand how dRP (deoxyribose-1-phosphate) could open new treatment avenues by encouraging the body to heal.
Dr. Giordano Pula, of University of Exeter Medical School, lead author says "We're very excited to provide new insights into how this particular molecule works to stimulate the formation of blood vessels in people. We now hope to be able to use this knowledge to trigger the formation of new blood vessels in patients where this is required for tissue regeneration, such as diabetic foot."
How does it work?
This study demonstrates the deoxyribose-1-phosphate's activation of NOX2 (NADPH oxidase 2 ) enzyme, responsible for an NFkB9 (Nuclear Factor Kappa B) transcription factor stimulation This NFkB transcription factor stimulation is in turn responsible for specific gene activation needed to initiate the formation of new blood vessels.
Among the genes activated in the chain of events that lead to blood vessel formation, the VEGFR2 (vascular endothelial growth factor receptor 2) plays a central role. This is considered to be the main target in the field of regenerative medicine and so the team hopes that this discovery might provide a cost-effective treatment for manipulating blood vessel formation.
Dr Pula's team is now planning to focus their investigation on the ability of deoxyribose-1-phosphate to stimulate skin repair by increasing the vascularisation of wounds and non-healing ulcers.
The team hopes this work will lead to new applications for treating conditions such as diabetic foot.
