“These mice demonstrated higher levels of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC1α) and mitochondrial transcription factor A – proteins that regulate mitochondrial biogenesis (the production of new mitochondria).”

“Neurons already lost were not restored, however, and protein clumps remained. In Parkinson’s, misfolded proteins damage mitochondria, leading to inefficient oxygen use and oxidative stress. Breathing low-oxygen air may reduce that oxidative stress.”

“Researchers studied the effects of exposure to abnormal tau on microglia, the brain's resident immune cells. They found that when microglia were exposed to abnormal tau, the mitochondria became "leaky," releasing their DNA into the cellular fluid.”

“Tau is a protein found in the brain. It plays critical roles in nerve axon stability and the transport of mitochondria, lipids, and cellular metabolites in the brain. New evidence suggests that high dietary salt intake increases the formation of tau tangles.”

“They found that participants who received the cocoa beverage had higher levels of endogenous antioxidants, correlating with less muscle damage. They also had higher levels of UQCRC2, a protein critical for energy production in the mitochondria.”

“Hyperthermia is a state of elevated core body temperature that activates molecular mechanisms that mitigate protein damage and drive the body's in-house repair systems. Mitochondrial biogenesis is the process by which new mitochondria are made inside cells.”

“They also measured gene and protein markers related to mitochondrial dynamics (how mitochondria join and divide to adapt to energy needs and separate damaged sections), autophagy (how cells break down and recycle damaged material), and mitophagy (the removal of damaged mitochondria) in a separate group of blood immune cells.”

“SIT and MICT improved peak oxygen uptake by 19 percent, indicating improved cardiorespiratory fitness. In addition, both groups demonstrated enhanced insulin sensitivity and increased levels of citrate synthase, a marker of muscle mitochondria content.”

“You can learn more about epigenetic mechanisms in our article here. Brown fat, also known as brown adipose tissue, is found in all mammals and is particularly abundant in newborns. Unlike white fat, brown fat is metabolically active tissue that is rich in mitochondria.”

“Tau is a microtubule-bound protein that forms the neurofibrillary "tau tangles" associated with Alzheimer's disease. Tau tangles disrupt the transport of metabolites, lipids, and mitochondria across a neuron to the synapse where neurotransmission occurs.”
