Reviewers publishing in Biology have elucidated SIRT1 functional reserve as an aspect of aging, describing how its depletion is an upstream cause of age-related disorders at the cellular level and explaining why many prospective therapies that increase SIRT1 and NAD+ have not had promising results. Managing a dangerous byproduct Reactive oxygen species (ROS) are necessarily...

Researchers have discovered why the protein AGGF1 has significant effects on blood pressure and published their findings in Aging Cell. Blood pressure is a condition of its own The authors begin their paper by discussing high blood pressure (hypertension), one of the most commonly known medical issues and a significant contributor to both disability and...

Scientists have created “nanoflowers” that nudge donor cells to produce more mitochondria, which can then be transferred to recipient cells to boost their mitochondrial function [1]. Mitochondrial transfer is difficult to improve Energy is required for life, and most energy in our cells is produced by mitochondria. When these organelles start to falter, it's a...

In a recent study that included data from humans, mice, and cell culture experiments, researchers demonstrated that gut microbes and their metabolites can profoundly influence the senescence of endothelial cells. They also explored the molecular processes underlying these changes [1]. Senescence in the blood vessels Endothelial cells line the inner surfaces of blood vessels, and...

Researchers have tested several combinations of ingredients with anti-aging properties. Those combinations, including a 12-ingredient formulation created by NOVOS, helped to reduce DNA damage and oxidative stress in human skin cells in cultures [1]. Fighting multiple Hallmarks of Aging at once Aging impacts multiple cellular processes, and these impacts can be assessed through biomarkers. The...

Researchers have published a method of rescuing cells from damaged mitochondria and cellular senescence, potentially alleviating major aspects of aging. Bad mitochondria must be consumed A core part of autophagy involves selective autophagy receptors (SARs), which build the autophagosomes in which the organelles are consumed [1]. Mitophagy is a subset of autophagy that refers to...
