London: In a promising research, scientists have discovered a blood vessel-creating gene that could be used to combat cancer, heart disease and strokes. The gene identified by researchers from the University of Leeds plays a vital role in blood vessel formation.

"Blood vessel networks are not already pre-constructed but emerge rather like a river system. Vessels do not develop until the blood is already flowing and they are created in response to the amount of flow," Professor David Beech, of the School of Medicine at Leeds, who led the research, said.

"This gene, Piezo1, provides the instructions for sensors that tell the body that blood is flowing correctly and gives the signal to form new vessel structures," said Beech.

"The gene gives instructions to a protein which forms channels that open in response to mechanical strain from blood flow, allowing tiny electrical charges to enter cells and trigger the changes needed for new vessels to be built," Beech said.

The research team is planning to study the effects of manipulating the gene on cancers, which require a blood supply to grow, as well as in heart diseases such as atherosclerosis, where plaques form in parts of blood vessels with disturbed blood flow.

"This work provides fundamental understanding of how complex life begins and opens new possibilities for treatment of health problems such as cardiovascular disease and cancer, where changes in blood flow are common and often unwanted," Beech said.

"We need to do further research into how this gene can be manipulated to treat these diseases. We are in the early stages of this research, but these findings are promising," Beech added.

"Blood flow has a major effect on the health of the arteries it passes through. Arteries are more likely to become diseased in areas where the flow is disturbed, for example," Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, said.

"This is because the endothelial cells lining the arteries are exquisitely sensitive to this flow and their response to changes can lead to disease, where the artery becomes narrowed and can eventually cause a heart attack," said Pearson. The research was published in the journal Nature.
