A recent study has suggested that A.Ceratii, a parasite that feeds on small life forms, including the ones that form algal blooms, contains mitochondria that have no mitochondrial DNA, and at least some of this DNA is found in the parasite’s own genetic code. However, a few genes found in humans are missing and replaced…

Last month, researchers at Johan Auwerx’s lab at the Ecole Polytechnique Fédérale de Lausanne (EPFL) had looked at the connections between RNA-binding proteins and aging. RNA binding proteins (RBPs) play an important part in post-transcriptional control by binding to mRNA. After binding, RBPs can aid in the processing of pre-mRNA as well as mRNA stability,…

Our work is largely supported by the generosity of our monthly patrons, the Lifespan Heroes, and this year, we will be showing our appreciation for that support with the launch of a brand new initiative – our new webinar series where you can meet the scientists working on the solutions to aging and age-related diseases….

Today, we will be covering another important root cause of aging, mitochondrial dysfunction, which is one of the Hallmarks of Aging [1]. What are mitochondria? Mitochondria, which are often called the powerhouses of cells, act like miniature factories, converting the food we eat into usable energy in the form of a chemical called adenosine triphosphate…

Today, we have an update from the MitoSENS team over at the SENS Research Foundation. As some of you may recall, MitoSENS was the first project we hosted on our research fundraising platform Lifespan.io back in August 2015. The project was successfully funded and raised $46,128, which was 153% of the funds needed. The extra…

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…

In what appears to be a world first, scientists at the University of Alabama at Birmingham have reversed two of the most common visual signs of aging—skin wrinkles and hair loss—in mice by turning off a gene responsible for mitochondrial dysfunction [1]. Study abstract Mitochondrial DNA (mtDNA) depletion is involved in mtDNA depletion syndromes, mitochondrial…

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…

Today, we will be taking a look at a new study showing that an NAD+ precursor was able to improve mitochondrial function in cells and flies with a model of Parkinson’s disease. Summary While mitochondrial dysfunction is emerging as key in Parkinson’s disease (PD), a central question remains whether mitochondria are actual disease drivers and…

Earlier this month, we covered a recent human clinical trial of the supplement MitoQ, which showed some interesting results. We thought that we would explore the publication a bit deeper, take a look at the figures, and discuss the findings in this month’s Journal Club. You can find the publication here. Abstract Excess reactive oxygen…
