Therapeutic strategies for spinal muscular atrophy
A Biological & Medical Sciences project
Spinal muscular atrophy (SMA) is a genetic disorder resulting
from defective production of a protein called Survival Motor Neuron, causing
damage to the motor neurons that control muscles needed for basic functions
such as breathing, swallowing and walking, leading to muscle weakness and loss.
The objective of this project is to use genetic modification technology to
understand fundamental processes occurring in motor neurons, allowing us to
understand how these processes go awry in SMA and how these might be treated
using delivery of functional genes to the motor neurons. This objective will be
carried out using viral vector technology, which are viruses derived from HIV
with all disease-causing genes removed and without the ability to permanently
insert themselves into the cell’s genetic material. This means that these
viruses can then safely deliver genetic material to the motor neurons. This
project will further develop viral vector technology with the aim of delivering
the gene Survival Motor Neuron 1 to both cells grown in a laboratory
environment and fetal mice. Genome editing (the inventors of which received the
2007 Nobel Prize in Physiology and Medicine) via a bacterial editing system
known as CRISPR-Cas will also be used to inactivate another protein that
accumulates in cells affected by SMA, causing further problems to these cells.
These objectives will elucidate further information that is necessary for the
next step using this tecnhology. This next step involves translation of this
information into therapeutic strategies which can be used in a clinical setting
to treat SMA.

What is your motivation for doing a PhD?
Research into new subjects is really exciting and feeds my curiosity
Why did you choose your research topic/title
I really want to research new treatments for a rare genetic disease!
1) Achieving first class honours in my undergraduate degree. 2) Presenting my project research at meeting of The Cardiovascular Society in London. 3) Publishing my undergraduate project in a well-respected American medical journal. 4) Being part of an amazing society, BioSoc, at university.
What difference will this research make in your life and the lives of others?
If successful, my research could lead to the development of a new and improved genetic drug, similar to one currently in clinical trials to improve the survival rate and quality of life of children suffering from spinal muscular atrophy. In my own life, my research will help to me to expand my scientific knowledge, increase my understanding of the human body and make me more determined to find a way to help those around me.
