In April this year MND clinician-researchers Professors Martin Turner and Kevin Talbot at the University of Oxford organised an information day about the rare, inherited form of MND called ‘Families for the Treatment of Hereditary MND’ (FATHoM). The day was filmed and podcasts of the talks have recently become available. This article gives an overview of each talk and a link to the video. Continue reading
What are fasciculations?
When motor neurones in the spinal cord become damaged this makes them electrically unstable, meaning they spontaneously discharge electrical impulses that cause small groups of muscles to contract. These contractions, known as fasciculations, are a common symptom of MND. Research suggests that they might be a good marker of motor neurone health.
Tracking fasciculations with surface EMG
Led by researchers Prof Chris Shaw and Prof Kerry Mills, Dr James Bashford is using technology called surface EMG to collect data on the site and frequency of fasciculations in different muscles in people with MND. Fasciculations in people with MND are different to benign fasciculations, which can occur in people without the disease and are generally harmless. James and the team hope to show that fasciculations in those with MND have a unique ‘fingerprint’ which can be accurately identified and tracked.
Data collected will be compared to other information currently used to track the progression of MND. James and the team hope surface EMG might provide a more sensitive way of measuring disease progression than previously used methods. This one year feasibility study is being carried out at King’s College London at a cost of £95,000 (our reference: 932-794). Continue reading
Induced pluripotent stem cell (iPSC) technology has enabled researchers to create and study living human motor neurones in the lab, derived originally from patient skin cells.
This project (our reference 80-970-797) is a collaboration between the labs of Professors Chris Shaw and Jack Price at King’s College in London and Siddharthan Chandran in Edinburgh. It aims to use the already collected white blood cell samples within the UK MND DNA Bank to create a larger number of new iPSC models of MND. Ultimately creating an MND iPSC cell bank, these models will enable researchers to better understand the disease and screen potential new drugs. Continue reading
A huge ‘atlas’ mapping the locations of motor neurone disease (MND) causing mutations within the genetic code has been collated. This has followed years of genetic analysis and sequencing of the DNA of people with MND, and their family members.
The people who have given their time and DNA have played a hugely important part in helping researchers learn more about MND, particularly the inherited form of the disease. Dr Benatar, who spoke in this session highlighted “there is a desire and interest by people who may have inherited MND to contribute to research into this disease, if not for their benefit then for the benefit to future generations of their family“.
The first session on day two of the Symposium looked at the topic of genetic testing and counselling. All the presentations had a common theme of this topic being a two-way street – after all the help people with MND and their families have given to help with research, now research efforts have been focussing on the ways to better help those who decide to have genetic testing for inherited/familial MND.

An international team of researchers, led by MND Association-funded researchers based at King’s College London, have identified mistakes in the TUBA4A gene as a new cause of the rare inherited form of MND.
This new MND-causing gene causes the cell’s structure, or skeleton, to break down – resulting in the cell being unable to transport molecules from one end of the cell to the other.
TUBA4A falls off the track
The TUBA4A gene is responsible for the Tubulin, alpha 4A protein and the researchers have found that the genetic mistake in the TUBA4A gene causes the microtubule network to breakdown in MND.
The microtubule network is a bit like a railway system. Normally, the healthy TUBA4A protein acts like a train, allowing the cell to transport molecules along this railway track to where they’re needed. As well as transporting molecules around the cell, the microtubule also acts as a skeleton within it (known as the ‘cytoskeleton’). Continue reading
Dr Samantha Price is the Research Information Co-ordinator at the MND Association. As well as organising the ‘blog a day’ during MND Awareness Month she also communicates the latest news about MND research. Here she blogs about the MND Association’s announcement of the UK Whole Genome Sequencing project.
It’s been a brilliant Awareness Month with blogs about zebrafish research and streaking meerkats. To end on a positive research note, we’re delighted to announce that we are funding a UK Whole Genome Sequencing project to help us understand more about the causes of MND. Utilising samples from our own UK MND DNA bank; researchers in the UK will aim to sequence 1,500 genomes to help identify more of the genetic factors involved in the disease. Continue reading
A packed room at the 24th International Symposium on ALS/MND was given a fascinating whistle stop tour covering stem cells, robots and cellular garbage clearing, by Dr Steve Finkbeiner of the University of California, as well as a glimpse into the future of developing ‘disease in a dish’ models of MND.
Dr Finkbeiner outlined how his lab is attempting to conduct “clinical trials in a dish” by generating huge numbers of cultured neurons cells for automated ‘high throughput analysis’ of their health and death. As he says, “we’re basically trying to develop a comprehensive physical examination for nerve cells”. Continue reading
“One in six of over-80 year olds will get a neurodegenerative disease. We’ve got to find ways to slow, stop or reverse these conditions” was the distinctly political message at the opening of this public symposia on “Degenerating Brains: new research into Alzheimer’s, Parkinson’s and Motor Neurone Disease”, run jointly by the Wellcome Trust and the Medical Research Council. The evening began with the world premiere of a short film explaining the importance of continuing to pursue research into these conditions (coming soon to an internet near you.. !).
The lectures started by Prof John Hardy’s excellent overview of genetics, illustrated by advances in Alzheimer’s Disease. “It’s the golden age for being a geneticist” he commented. I particularly enjoyed his explanation of the much quoted research paper by Manolio et al 2009 (Its Figure 1 in this OPEN ACCESS (yeah!) paper –if you really want to look at it!). “There are now recipes for finding causes of diseases that fall anywhere on this graph” Prof Hardy explained. Whether they are rare genetic mistakes that have a big impact (make a big contribution) on whether someone develops a condition) or more common genetic mistakes that have a smaller overall contribution. His closing comment “Geneticists are finding the jigsaw pieces to give to the cell biologist and neuropathologists to put together”, was a theme that the next speaker, Prof Chris Shaw, continued.
Prof Shaw, MND Association grantee, eminent scientist and clinician based at King’s College London, began his talk by laying down a challenge to the younger generation of scientists in the audience “I’m banking on you to find the answers to my degenerating brain”. He went on to explain how the discovery of genetic mistakes in SOD1, TDP-43 and FUS has led us to a greater understanding of the biological pathways involved in motor neurone degeneration in MND. Prof Shaw’s research has led him to develop close relationships with families affected by the rare, inherited form of MND and he ended his talk with a thank you to them for their help.
The concluding presentation was given by Prof David Rubenstein from Cambridge University, describing how advances in understanding Huntingdon’s disease research will act as a model for driving advances in other neurodegenerative diseases.
The consortia of funded researchers have got together to create a blog site for posts about Alzheimer’s Disease, Motor Neurone Disease or Parkinson’s Disease, why not add this link to your favourites too (and if you’re a twitter fan, you can follow them @dneurons ) http://degeneratingneurons.wordpress.com/.
Every March, Brain Awareness Week (11 – 17 March 2013) unites people of all ages worldwide to raise awareness of brain research. There are 45 free events across the UK, including seminars and school visits.
On the evening of the 11 March Belinda attended the free award ceremony for the winner of the Europe PubMed Central-led science writing competition ‘Access to understanding’, which included a large number of entries on an MND paper.
On the 13 March University College London (UCL) will be running a free public symposia on ‘Degenerating Brains’. As well as talks on Alzheimer’s and Parkinson’s disease, Prof Chris Shaw (King’s College London) will be speaking about MND. Due to the popularity of this event it is now fully booked.
Our Brain Research
Dr Martin Turner’s BioMOx project MND Association funded researcher Dr Martin Turner at the University of Oxford has identified a pattern of degeneration in the brains of people with MND that is linked to the level of disability.
Continuing and expanding BioMOx Dr Martin Turner has also been awarded his second MRC/MND Association Lady Edith Wolfson Clinical Research Fellowship to carry on his BioMOx project which is to begin in August 2013.
Dr Turner will be broadening the BioMOx project to include people identified as being at risk of developing MND from families with a history of the disease but who are not yet showing symptoms.
Dr Tennore Ramesh’s interneuron findings A recent study by Association funded researcher Dr Tennore Ramesh from the Sheffield Institute for Translational Neuroscience (SITraN) has shown that even before the symptoms of MND occur, at the earliest stages of the disease, ‘connector neurones’ known as interneurons are already becoming damaged in the zebrafish.
Prof Mara Cercignani’s MRI scans project Starting in October 2013 Prof Mara Cercignan’s Association funded PhD studentship will use brain magnetic resonance imaging (MRI) scans that have already been obtained from many studies at King’s College London over the past 16 years.
This project will apply new ideas in medical computing to old data in order to identify how MRI changes in the brains of people with MND evolve. This will then enable the development of a new method to ‘stage’ MND progression so that brain abnormalities can be detected earlier.
Tissue Donation and MND
Tissue donation is a generous gift that can make a vital contribution towards MND research. Researchers investigating MND are particularly interested in the whole of the brain and spinal cord tissue, otherwise known as the central nervous system (CNS).
A brain and spinal cord tissue donation is made from either a healthy individual or somebody with MND after their death. To find out more information about tissue donation please see our information sheet on our website.
Raise Awareness of MND
Our 2013 Awareness Month campaign is focussed around a film called I Am Breathing. The hard-hitting documentary tells the story of Neil Platt, who was diagnosed with MND just after his son, Oscar, was born.
Neil wanted to leave a legacy for Oscar and also raise awareness of MND. We hope that thousands of people will see the film on or after a special Global Screening Day, Friday 21 June, Global MND Awareness Day.The Association has joined forces with the film makers, the Scottish Documentary Institute, and with Neil’s family to make sure this powerful story is shared as widely as possible when the film is released during the Awareness Month in June 2013.
You can help fulfil Neil’s goal of raising awareness by hosting your own screening of I Am Breathing on 21 June 2013 – MND Global Awareness Day.
It was a chilly -15oC in New York on Sunday night, but the temperature on Monday morning was considerably higher – fuelled in part by anticipation of the presentations and debate to come – as 60 delegates from 14 countries gathered for a workshop on the use of stem cells in research and treatment of ALS/MND.
As many of the leading names in the field started filing into the meeting room, I found myself thinking (rather morbidly) that if the hotel blew up, research in this field would be set back a decade…
Learning from the past to push stem cell research forward
The opening session was motivating, with Dutch neurologist Prof Leonard van den Berg and MND Association funded researcher Prof Chris Shaw providing overviews of our current understanding of the causes of MND and the clinical and pathological ‘spectrum’ of the disease.
A lot of Prof Shaw’s presentation focused on the TDP-43 protein, which is a ‘pathological hallmark’ of dying motor neurones. It struck me that scientists understanding of TDP-43 appears to be accumulating faster than it did for SOD1, 15 years ago – a consequence of the advances in technology and the fact that there are many more researchers around the world working on MND these days.
Dr Lucie Bruijn, science director of our counterpart organisation in the USA –the ALS Association, concluded the opening session with a scene-setting presentation, highlighting the work that has been done over many years in developing motor neurone cell cultures (from mice and rats) and using these to screen for potential protective drugs.
There have been many challenges every step of the way, but the learning from these past studies will be vital in moving stem cell research forward in the future.
In the next few blog posts, I will take you on a whistle stop tour of the questions asked by 60 of the world’s leading MND stem cell researchers at the stem cell workshop and the answers we were met with so stay tuned…
