In mice and human patients, researchers found that crippling of protective enzyme Prx2 leads to death of dopamine-producing neurons in Parkinson's disease. Activating Prx2 prevents neuronal loss, suggesting it as a beneficial target for PD treatment.
Researchers at Johns Hopkins found that cancer cells can reprogram themselves to use less oxygen and more glucose, allowing them to survive and spread. The loss of a single gene causes cancer cells to stop making mitochondria, leading to the use of fermentation for energy production.
Researchers discovered how cells fine-tune oxygen use to make do with limited availability. They found that under stress, cells replace one protein with an energy-efficient substitute to maintain power production.
Scientists from Harvard University and the University of Pittsburgh found that carbon monoxide reduces or shuts down inflammatory responses by releasing chemical signals in mitochondria. This discovery raises hopes for developing new anti-inflammatory therapies, such as low levels of inhaled carbon monoxide.
The St. Jude study found that cells shift their biochemical activities to conserve energy by increasing glucose production and recycling CoA, a key player in metabolism. The researchers also showed that PanK controls the concentration of CoA in specific locations within the cell.

The new tool detected nearly three dozen variations in the non-coding D-loop region, improving its sensitivity and reproducibility.
Research reveals that differences in overall muscle efficiency cannot be explained by variations in individual mitochondria's ability to convert food energy into ATP. Instead, the findings suggest that ATP usage within the muscle plays a crucial role in determining efficiency.
A multidisciplinary team at UCI will investigate the connection between genetic variations in mitochondria and metabolic syndrome symptoms. The research may lead to new diagnostic tools and treatments for conditions like diabetes and cardiovascular disease.
Researchers found that old mitochondria are leaky, reducing ATP production and making normal activities challenging for the elderly. This inefficiency affects muscle cells' ability to produce useable energy.
Research by Yale University found that insulin-resistant individuals' mitochondria produce less ATP, a key energy molecule. This defect may explain the link between inherited type 2 diabetes risk and reduced insulin signaling.
