Does a Mechanism Linking Cellular Aging to Cellular Quiescence Exist?

Listen to a blog summary of a trending research paper published by Oncotarget on July 28, 2022, entitled, "Diverse geroprotectors differently affect a mechanism linking cellular aging to cellular quiescence in budding yeast." ______________________________________ The mechanisms of cellular aging and cellular quiescence have been preserved throughout evolution. Cellular quiescence is a temporary state of cell cycle arrest and low metabolic activity. Importantly, quiescent (Q) cells maintain the ability to quickly activate and re-enter the cell cycle (in response to the appropriate stimuli). Recent research has shown that cellular quiescence may play a role in cellular aging. In a 2020 study, research findings indicated that the rate at which yeast cells age is determined by a complicated program that affects 1) when a state of quiescence is entered, 2) how long quiescence is maintained and 3) when the cell exits quiescence. Researchers found that caloric restriction (CR) (a geroprotective intervention) appears to remodel this program, and this remodeling could be responsible for the CR-dependent delay of yeast chronological aging. Thus, the researchers considered the question: Does a single mechanism exist which links cellular aging to cellular quiescence? “We have introduced a new yeast model for studying mechanisms linking cellular aging to cellular quiescence [109, 110].” In a new study, researchers (Anna Leonov, Rachel Feldman, Amanda Piano, Anthony Arlia-Ciommo, Jennifer Anne Baratang Junio, Emmanuel Orfanos, Tala Tafakori, Vicky Lutchman, Karamat Mohammad, Sarah Elsaser, Sandra Orfali, Harshvardhan Rajen, and Vladimir I. Titorenko) from Concordia University, Montreal, used a new yeast model to test their hypothesis that a mechanism exists linking cellular aging to cellular quiescence. On July 28, 2022, their research paper was published in Oncotarget and entitled, “Diverse geroprotectors differently affect a mechanism linking cellular aging to cellular quiescence in budding yeast.” Full blog - https://www.oncotarget.org/2022/08/05/does-a-mechanism-linking-cellular-aging-to-cellular-quiescence-exist/ DOI - https://doi.org/10.18632/oncotarget.28256 Correspondence to - Vladimir I.
