Hydrogen peroxide induces p16(INK4a) through an AUF1-dependent manner.

Elevation of p16(INK4a) has been described as an important mechanism for hydrogen peroxide (H2O2)-induced replicative senescence. However, the mechanisms underlying remain unknown. In this study, we demonstrate an important role of RNA-binding protein AUF1-mediated mRNA turnover in H2O2-induced p16(INK4a) expression.
