In Aging Cell, researchers have described how the enzyme Pck1, a core part of metabolic activity, is required for staving off senescence in fat (adipose) cells. The aging of fat With the decrease in metabolic activity that frequently occurs with aging, human beings often accumulate fat. This fat, itself, also ages; this paper describes it...

Researchers publishing in Aging Cell have discovered that using FGF21 to upregulate the sirtuin SIRT1 delays spinal disc degeneration in a rat model. A common cause of lower back problems Intervertebral disc degeneration (IDD) is one of the core reasons for lower back pain in older people. This nearly ubiquitous problem is a frequent target...

Cellular senescence, a state in which cells stop dividing but resist dying, accumulating in tissues over time, has emerged as one of the most promising targets in longevity medicine. Senescent cells actually serve important roles in development, wound healing, and cancer prevention, but as they accumulate with age or pathology, they become harmful: they secrete...

A new study identified two polyunsaturated fatty acids, α-eleostearic acid (α-ESA) and α-ESA methyl ester (α-ESA-me), that showed senolytic activity in cell cultures and a mouse model [1]. An anti-aging strategy Cellular senescence is one of the most critical aging-related processes. Senescent cells, which accumulate with age, are arrested in the cell cycle and are resistant...

Researchers publishing in Aging Cell have discovered that the nuclei of the cells that line injured arteries quickly become misshapen and that this leads to accelerated cellular senescence. Delivering zinc to these cells partially alleviates this dysmorphism. Two seemingly unrelated concepts This paper begins with a discussion of two different concepts that, on the surface,...

The European Heart Journal has published a review of what happens to the human heart as it ages, noting the cellular effects of mitochondrial dysfunction and cellular senescence along with more visible changes such as hypertrophy and fibrosis. A constantly working organ The reviewers begin this paper by noting the constant work of the heart,...
