The Claim

In renal tubular epithelial cells, endoplasmic reticulum stress induced by tunicamycin or thapsigargin increases ATF4 and p16 expression and induces cellular senescence, and silencing ATF4 or p16 prevents this senescence.

How it works
1 study reviewed
In plain English

In kidney tubule cells, chemicals that disrupt the endoplasmic reticulum increase ATF4 and p16 protein levels and cause cells to enter a senescent state; blocking either ATF4 or p16 prevents this senescence.

See the scientific wording

In renal tubular epithelial cells, endoplasmic reticulum stress inducers such as tunicamycin and thapsigargin increase ATF4 and p16 expression and induce cellular senescence, which is prevented by silencing either ATF4 or p16, supporting the role of this pathway in stress-induced aging.

Why this might work

When the endoplasmic reticulum in kidney tubule cells is stressed, it triggers a signal that turns on ATF4, which then increases the production of p16. High levels of p16 stop the cells from dividing, forcing them into a permanent resting state called senescence, which causes them to swell and accumulate damage.

    When kidney cells are stressed, they turn on two proteins (ATF4 and p16) that make them age faster; if scientists block either protein, the cells don’t age. This study showed that happens even when the stress comes from sugar-related damage, proving the same pathway works.
