In a new study, researchers have identified a direct link between mitophagy and inflammation. Aging is accompanied by rising levels of oxidative stress, which is primarily caused by our cellular power plants, the mitochondria. As we age, our mitochondria start to produce an increasing amount of oxidized molecules known as reactive oxygen species (ROS), which…

According to scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, or DKFZ), the enzyme TXNIP, which inhibits the enzyme TRX-1, might be a regulator of aging and might be a viable candidate for future interventions against age-related diseases [1]. Study summary The “free radical theory of aging” suggests that reactive oxygen species (ROS) are…

The mitochondria are the powerhouses of the cell, producing ATP, a kind of universal energy used in cellular functions. Mitochondrial dysfunction is an important part of the aging process. As cells age, the effectiveness of the respiratory chain diminishes, increasing electron leakage and reducing ATP generation [1]. As mitochondria become more dysfunctional with age, there…
