DEVELOPMENT OF AN INNOVATIVE GENE THERAPY METHOD TO CURE MITOCHONDRIAL AGING-
"BACKING UP" THE MITOCHONDRIAL GENOME
Background:
Mitochondria, the power plants of the cell, contain their own DNA. Unlike the nucleus, mitochondria lack an efficient system to repair damaged DNA, and this damage accumulates over time. As we age, these accumulated mutations result in an increase in oxidative stress throughout the body. It is no coincidence that organisms which age more slowly consistently display lower rates of mitochondrial free radical damage. Reversing and/or preventing damage to mitochondrial DNA may be a key factor in slowing the aging process.
The Research Project:
In this project, engineered mitochondrial genes will be used to restore function to cells that contain defective mitochondrial genes.
The SENS team is developing a unique method for targeting these genes to the mitochondria; this step has been the bottleneck in research on this topic over the last decade. In their system, the mRNA from the engineered mitochondrial gene is targeted to the mitochondrial surface before it is translated into a protein using a co-translation import strategy. Once imported, it is incorporated into the correct location in the inner mitochondrial membrane. The long-term goal of this project is to utilize this improved targeting strategy to rescue mutated mitochondrial DNA and thereby prevent and cure one of the major causes of cellular aging.
