Mitochondrial diseases are often deadly disorders that have no cure. Experts have long been searching for a way to effectively treat these complex conditions – and now, new research points to a potential drug target that can rescue cells suffering from mitochondrial dysfunction, reports Fox News.

Often referred to as the “cellular power plants,” mitochondria are responsible for generating adenosine triphosphate (ATP) – the cell’s primary energy source. But for patients suffering from mitochondrial disease, their cells’ mitochondria do not function properly, leading to cell injury and even cell death.

“With mitochondrial diseases, there are a variety of different outcomes, but there is consistency in terms of muscle degeneration, metabolic changes in the blood, drop in blood pH, and neuronal effects. But really all tissues can be affected,” lead researcher David Sabatini, of the Whitehead Institute and Massachusetts Institute of Technology, told FoxNews.com.

Mitochondrial disorders range in severity, and many individuals can expect to live ordinary lives. However, some children with more severe forms of the disease cannot see, hear or walk, and many may not survive past their teenage years.

Hoping to find a method for treating this condition, MIT graduate student Walter Chen and postdoctoral researcher Kivanc Birsoy mimicked mitochondrial dysfunction by giving cells a small molecule drug called antimycin that inhibited the mitochondrial electron transport chain – the method by which ATP is generated.

After suppressing mitochondrial function, Chen and Birsoy found that cells with mutations inactivating the ATPIF1 gene showed substantial resistance against mitochondrial toxins and were often saved from cell death. The ATPIF1 gene acts somewhat like a backup system by preventing starving cells from consuming too much of their ATP, but in return, this actually worsens the mitochondrion’s membrane potential. So for patients with mitochondrial disease, the activation of the ATPIF1 gene is actually harmful.

Since liver cells are frequently affected in patients with mitochondrial disease, the researchers suppressed mitochondrial function in mice with genetically inhibited ATPIF1 and a group of control mice. As expected, the liver cells in the mice without ATPIF1 dealt much better with mitochondrial dysfunction than the control mice.

These findings indicate that suppression of ATPIF1 in patients with mitochondrial disorders may slow or stop symptoms of the disease. However, Sabatini noted that inhibiting the protein encoded by ATPIF1 protein may not be a feasible option for future treatments.

Instead, Sabatini said potential therapies could utilize genome editing which involves using genetically modified nucleuses to alter specific sequences in the genome.
