In Aging Cell, researchers have described the way that antioxidants work against senescence in muscle cells by altering mTOR signaling. Senescent cells don't sense nutrients properly Deregulated Nutrient SensingThe four pathways of nutrient-sensing regulate metabolism and influence aging. The four associated key protein groups are IGF-1, mTOR, sirtuins, and AMPK. We call these proteins “nutrient-sensing”...

Publishing in Aging, a team of researchers has discovered how puerarin, an extract of kudzu, ameliorates chronic obstructive pulmonary disorder (COPD) signs in cellular cultures by limiting mitophagy: the consumption of mitochondria by cells. When autophagy isn't a good thing Mitophagy is a subset of autophagy, the consumption of any organelle by a cell. This...

In a study published in Aging, Chinese researchers have described how they used computer modeling in order to create a new rapalog that is designed to reduce the long-term impact of stroke. Reperfusion injury, autophagy, and mTORC1 Stroke and other ischemic events, such as heart attack, occur when a blockage causes blood to stop flowing...
