Tag: Hallmarks of Aging

A review paper published in Cells has described multiple ways in which the secretion of extracellular vesicles (EVs) changes with aging, leading the authors to propose it as its own hallmark. Extracellular vesicles and their uses This review begins with an outline and explanation of extracellular vesicles and their classifications. Cells use extracellular vesicles to...

The year 2023 started with the publication of two remarkable review papers in Cell and Cell Metabolism by researchers addressing the hallmarks of aging and their interplay with the hallmarks of cancer [1,2]. These papers were authored by the same team that published the original 2013 Hallmarks of Aging paper [3]. The Hallmarks of AgingThere...

In a new review article published in Frontiers in Cell and Developmental Biology, researchers have suggested adding cellular enlargement to the hallmarks of aging [1]. Bigger is not always better Different cell types are known to have different shapes and sizes, which are dictated by their functions. In humans, sperm cells (male gametes) and ova...

Researchers publishing in Nature Communications have determined that interventions that extend lifespan in mice may not have significant effects on the processes of aging. Improvement is not the same as slowing decline The researchers begin this paper by noting that previous studies have outlined a broad variety of dietary, environmental, and genetic factors that are...

Publishing in Aging five months after their panel discussion in Copenhagen, many well-known researchers have explained their reasons for wishing to add new hallmarks of aging to the existing paradigm. A new addition to an old paradigm What is Aging? The Nine Reasons We AgeAging is a series of processes that include direct damage, accumulation...

Scientists have shown that only some of the hallmarks of aging affect methylation clocks that are used to measure biological age [1]. The big black box Epigenetic clocks that measure biological age based on aging-related changes in genome methylation have been a great success. They enable researchers to analyze the effects of various interventions on...
