SCIENTISTS say they are a step closer to finding new ways to treat Parkinson's after mapping out a stage-by-stage picture of how the disease develops.
Researchers at Dundee University captured the way in which mutations in a gene lead to the most prevalent inherited form the disease.
The gene, PARK2, makes a protein called parkin and it is thought that the way in which this protein is activated leads to the development of the condition, a neurodegenerative disorder.
The scientific team said the work gives further understanding of the possible causes of Parkinson’s disease and offers potential for multiple targets for therapeutics to be developed.
Dr Helen Walden at the University of Dundee, said: “What we have done is work out how parkin is kept switched off, and how it is switched on. It is necessary for it to be switched off because it is only needed under certain conditions.
"By defining the multiple steps needed for going from off to on, we have provided the information needed to modulate each step. This is important because it reveals the mechanics behind a process that goes wrong in so many cases of Parkinson’s Disease.
“The fact there are several different stages offers the possibility of different ways to tackle the problems that occur in mutations of the gene and the subsequent activation, or lack of it, of parkin.”
The research was published in The EMBO Journal.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
