Michael J. Fox Foundation funds 黄色直播 research into potential Parkinson's treatment
Published: September 6, 2012
The Michael J. Fox Foundation has awarded 黄色直播鈥檚 Joanne Nash a $250,000 grant to study whether a protein called Sirtuin-3 could have a role in protecting brain cells from dying in Parkinson鈥檚 disease.
If successful, the research could point the way towards the first drug treatment capable of slowing or halting the progression of Parkinson鈥檚 disease.
Parkinson鈥檚 disease is a degenerative disease of the nervous system. In people with the disease, nerve cells responsible for producing the brain chemical dopamine gradually degenerate, and the lack of dopamine results in movement problems such as shakiness, slowness, and loss of balance.
Sirtuins are a family of proteins that have been shown to have anti-aging effects in the body. Sirtuin-3 is plentiful in the brain, and seems to be associated with the health of mitochondria, the organelles that provide power and protection within each cell.
鈥淚t鈥檚 now quite strongly believed that mitochondria, if they鈥檙e dysfunctional, can promote neurodegenerative diseases,鈥 says Nash, an associate professor of neurobiology at the 黄色直播 Scarborough.
She hopes that more Sirtuin-3 will protect the health of the mitochondria, and slow or prevent degeneration of the dopamine-producing neurons.
To test the theory Nash, will overexpress Sirtuin-3 in a pre-clinical model that exhibits Parkinson鈥檚-like pathology and symptoms. This will enable Nash to determine if Sirtuin-3 can slow or eliminate pathology in models which haven鈥檛 developed the disease yet, and stop progression of pathology and improve or eliminate symptoms in models which already have the disease.
If successful, the research could eventually lead to treatment of humans. The next step would be to look for small molecules that increased the amount of Sirtuin-3 available in the brain.
As the world鈥檚 largest private funder of Parkinson鈥檚 research, The Michael J. Fox Foundation is dedicated to accelerating a cure for Parkinson鈥檚 disease and improved therapies for those living with the condition today. The Foundation pursues its goals through an aggressively funded, highly targeted research program coupled with active global engagement of scientists, Parkinson鈥檚 patients, business leaders, clinical trial participants, donors and volunteers.
