Osteoblasts
Researchers publishing in Aging have uncovered some of the molecular mechanisms behind why mesenchymal stem cells (MSCs) do and don't differentiate into bone-building osteoblasts, unlocking a potential new approach to osteoporosis. A matter of cellular fate MSCs are downstream of pluripotent stem cells: they can differentiate into multiple cell types, but not every somatic cell...
Disagreeing clocks
A paper published in Aging goes into detail about the proteins and RNA pieces that increase and decrease with aging, suggesting a multiple-clock approach to biomarkers. Blood proteins change with age The researchers start out by discussing existing clocks based on such measurements as imaging [1] and epigenetic methylation [2], which is the most well-known...
Elderly Blood Draw
Published in GeroScience, a groundbreaking study from the renowned Conboy lab has confirmed that plasma dilution leads to systemic rejuvenation against multiple proteomic aspects of aging in human beings. Systemic molecular excess This paper takes the view that much of aging is driven by systemic molecular excess. Signaling molecules, antibodies, and toxins, which gradually accumulate...
Omics
The latest research in Aging Cell has brought to light new insights into the biology of aging and associated therapeutic candidates. What is multi-omics? "-omics" refers to branches of molecular biology that attempt to characterize and/or quantify their components in totality, often using recently developed big data technologies. For example, genetics is the study of...
DNA data
A new analysis has revealed a core set of genes involved in aging in both humans and mice. Together with a broader set of age-related genes assembled by the study [1], this resource will serve as a launching point for further investigations of the mechanisms behind aging and age-related diseases. The heart of the matter...
Recently, a group of South Korean scientists has analyzed the blood proteome of mice to determine how it changes with age and to identify aging-related proteins that have previously eluded researchers. After identifying several such proteins, the group focused on a specific protein, cadherin-13, that seems to prevent age-related bone loss [1]. The plasma proteome...
