In light of the upcoming Biomedical Research Advisory Panel meeting happening on Friday 7 April that will discuss which new research projects the MND Association will fund, we are pleased to report on the progress of one of our already-funded researchers. In their three year project, funded by the MND Association, Prof Annalisa Pastore (King’s College London) and Prof Gian Tartaglia (University Pompeu Fabra, Barcelona) are investigating the process by which TDP-43 binds to RNA. Below is a summary of the progress they made during their first year.
Background to the project
Annalisa Pastore, King’s College London
One of the causes of amyotrophic lateral sclerosis (ALS), the most common type of motor neurone disease (MND), is related to faulty functioning of the TDP-43 protein, a component that is naturally present in all of our cells. In healthy cells, TDP-43 resides in the centre of a cell (the nucleus) where it attaches to RNA and supports correct gene expression – that is, it helps to extract information carried by a gene to form proteins, the main building blocks of our bodies.
MND Association and Alzheimer’s Research UK-funded researchers from University College London have identified that toxic proteins may cause motor neurones to die in C9orf72 MND and frontotemporal dementia. Published open access in the journal Science on Thursday 7 August, this research explains more about one of the most common forms of inherited MND.
