The finding identifies how vulnerable cell groups react and respond differently to the accumulation of mitochondrial DNA damage seen in the disease, highlighting the need for cell - specific treatments. (sciencedaily.com)
The team found that the levels of mitochondrial DNA, presumably released from dying neurons, were increased in the blood plasma of mice that were starting to develop the symptoms of HD. (sciencedaily.com)
This leads to the imbalance of ingredients required for DNA synthesis, and consequently to genetic damage and / or reduction of mitochondrial genome amount. (sciencedaily.com)
