“…More importantly, cell fate is regulated by P53 dynamics [24] . These facts have driven a number of theoretical studies to identify the potential dynamics of P53 controlled by its key regulator using the bifurcation method [25] , [26] , [27] , [28] , [29] , [30] . The mainstream point of view is that P53 oscillation requires a P53-MDM2 negative feedback loop (NFL) gene network structure.…”
