The elimination of these glia in the mouse brain ameliorated the development of Parkinsonian neuropathologies induced by the pesticide toxin paraquat.  

The removal of senescent cells in mice leads to an increased lifespan and later onset of age-linked diseases, scientists show.

In Chapter 12, "Of Mice and Men," author Sue Armstrong recounts the point at which researchers moved from working with p53 in tissue culture to studying the gene in animal models.

The tale of p53, a widely studied tumor suppressor gene, illustrates the inventiveness of researchers who turn mishaps into discoveries.

Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement.
