Downregulation of YAP Activity Restricts P53 Hyperactivation to Promote Cell Survival in Confinement.

Cell migration through confining three dimensional (3D) topographies can lead to loss of nuclear envelope integrity, DNA damage, and genomic instability. Despite these detrimental phenomena, cells transiently exposed to confinement do not usually die. Whether this is also true for cells subjected to long-term confinement remains unclear at present.
