Abstract:
The nuclear envelope is a highly dynamic structure that reversibly disassembles and reforms at mitosis. The nuclear envelope also breaks down - irreversibly - during apoptosis, a process essential for development and tissue homeostasis. Analyses of fixed cells, time-lapse, imaging studies of live cells and the development of powerful cell-free extracts derived from gametes or mammalian somatic cells have provided insights on the fate of nuclear envelope proteins during mitosis and apoptosis, and on the mechanisms behind nuclear envelope modifications in these processes. In this review, we discuss evidence leading to our understanding of the dynamics of the nuclear envelope alterations at mitosis and during apoptosis. We also present novel imaging and genetic approaches to the study of nuclear envelope dynamics and function.
