People with the commonest form of motor neuron disease (MND) called amyotrophic lateral sclerosis (ALS) are more likely to have relatively long ring fingers, reveals research from the Institute of Psychiatry (IoP) at King’s.
MND is a serious neurodegenerative disease that results in progressive paralysis and eventual death from respiratory failure. On average, a person survives two years after being diagnosed. The cause of the disease is still mainly unknown, although prenatal factors are thought to be important.
Genetic factors are known to contribute to MND. In both men and women, motor neurons are dependent on testosterone for survival. Men are more likely than women to develop MND and are also exposed to higher levels of testosterone before birth.
The scientists, led by Professor Ammar Al-Chalabi from the IoP, suspected that it was the high prenatal testosterone level rather than male sex itself that was a risk factor for the development of MND in later life, perhaps because this makes the adult motor neurons less sensitive to testosterone.
The researchers looked at the ratio of the lengths of a person’s index finger to ring finger – known as the 2D:4D ratio. This is calculated by dividing the length of the index finger of the right hand by the length of the ring finger.
A low ratio means the ring finger is relatively long compared with the index finger and is thought to be an indicator of high prenatal testosterone levels in men and women (and is probably the reason why on average men have longer ring fingers than index fingers, while women often do not).
The study involved 110 participants with useable results and used a digital camera to photograph hands, finger length was measured and ratios were calculated between fingers.
The 2D:4D ratio was consistently lower for people who had the ALS form of MND compared to those without.
Professor of Al-Chalabi said: ‘This work suggests that even before birth, motor neurons can be affected in ways that make them more vulnerable in later life. Finger lengths seem to be linked to the balance of hormones in the womb, so what we see as a trend towards longer ring fingers is just a marker for the hormone balance during pregnancy. The same trend is seen in sporty people and men, which is why this can never show someone will get motor neuron disease, it is just a clue as to what might be making motor neurons more fragile.’
‘Low index-to-ring finger length ratio in sporadic ALS supports prenatally defined motor neuronal vulnerability’ is published in the Journal of Neurology, Neurosurgery and Psychiatry. http://jnnp.bmj.com/content/82/6/635.full?sid=83b5f70c-b897-4e71-b7c2-b64cbdcd5768

Stem cellsCancer Research UK-funded researchers at King’s College London have identified a way of eliminating leukaemic stem cells, which could in the future lead to new treatments that may enable complete remission for leukaemia patients. An early study in mice has shown that leukaemic stem cells can be abolished by suppressing two proteins found in the body. Leukaemic stem cells sustain the disease and are likely to be responsible for relapse, so elimination of these cells is believed to be key for achieving complete remission. These encouraging findings highlight the two proteins as potential therapeutic targets to prevent the most aggressive forms of leukaemia returning.
Patient organizations, academic and industry join forces to develop and assess novel treatment approaches for autism. An international consortium of scientists, led by Roche and King’s College London, has launched one of the largest ever research academic-industry collaboration projects to find new methods for the development of drugs for autism spectrum disorder (ASD). European Autism Interventions – A Multicentre Study for Developing New Medications (EU-AIMS) is the largest single grant for autism research in the world and the largest for the study of any mental health disorder in Europe. EU-AIMS brings together top scientists from academic institutions with a wide range of expertise, and partners them with major global drug companies from the European Federation of Pharmaceutical Industry Associations (EFPIA) including Roche, Eli Lilly, Servier, Janssen Pharmaceutica, Pfizer and Vifor Pharma; as well as world leading autism charities including Autism Speaks (USA). King’s College London leads an academic partnership of 14 European centres of excellence comprising Biozentrum, University of Basel (Switzerland), Birkbeck, University of London (UK), Cambridge University (UK), Central Institute of Mental Health Mannheim (Germany), Commissariat à l’Energie Atomique et Aux Alternatives (France), the European Molecular Biology Laboratory (Germany), Institut Pasteur (France), Institute of Education (UK), Karolinska Institutet (Sweden), Max-Planck Institute of Experimental Medicine (Germany), Radboud University Nijmegen Medical Centre (The Netherlands), University "Campus Bio-Medico” (Italy), University Medical Centre (The Netherlands) and University Ulm (Germany). Two other pharmaceutical small and medium-sized enterprises (SME): deCode Genetics (Iceland) and NeuroSearch (Denmark) will contribute to the success of EU-AIMS, while the SME GABO:mi (Germany) will be managing the project. Professor Declan Murphy, King’s College London said: “This ground-breaking integrated research effort is unprecedented and is designed to allow us to change the scientific landscape of autism research and clinical drug development throughout Europe.” ASD affects an estimated 1% of children worldwide and more children will be diagnosed with autism this year than with AIDS, juvenile diabetes and pediatric cancer combined. With a wealth of knowledge and research findings related to ASD emerging every year, it has been hard to take these findings from the bench to the clinic. Robert Ring, Vice President of Translational Research for Autism Speaks said: “The lack of effective pharmacological treatments for ASD has a profound effect on patients’ lives. We are excited that with this unique collaboration we may see a real shift in future treatment for this devastating disorder.” EU-AIMS will focus on three areas: the development and validation of translational research approaches for the advancement of novel therapies for ASD; the identification, alignment, and development of expert clinical sites across Europe to run clinical trials; and the creation of an interactive platform for ASD professionals and patients. By the end of the five-year project, EU-AIMS expects to provide novel validated cellular assays, animal models, new fMRI methods with dedicated analysis techniques, new PET radioligands, as well as new genetic and proteomic biomarkers for patient-segmentation or individual response prediction. It aims to establish a research network that can then move on to testing the investigational treatments in humans. Luca Santarelli, Global Head of Roche Neurosciences said: “This collaborative effort is in full alignment with Roche Neurosciences strategy which is to develop personalized treatment options for serious patient needs.” Will Spooren, Project Coordinator of EU-AIMS and group leader Behavioral Pharmacology at Roche Neuroscience, added: “Recent genomic and functional studies have shed light on the pathophysiology of autism. We need to work together if we want to fully harness those developments and pave the way for new treatment options which would cluster ASD patients sharing common pathophysiological features.” The research of EU-AIMS receives support from the Innovative Medicines Initiative Joint Undertaking under grant agreement n° 115300, resources of which are composed of financial contribution from the European Union's Seventh Framework Programme (FP7/2007-2013), from the EFPIA companies’ in kind contribution and from the Autism Speaks resulting in a total of €29.6 million. The project is part of the Innovative Medicines Initiative (IMI), Europe's largest public-private initiative aiming to speed up the development of better and safer medicines for patients. IMI supports collaborative research projects and builds networks of industrial and academic experts in order to boost pharmaceutical innovation in Europe.
