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, appear to be unrelated. First, the researchers discuss vascular damage, particularly in the context of surgeries; even minimally invasive procedures that involve cutting, scraping, or burning arteries must cause some level of damage. This includes such procedures as catheter implantation as a treatment for heart disease [1] and the resection of cancerous tumors [2].
