A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.

Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The process in which the migration of an axon growth cone is directed to a specific target site along the dorsal-ventral body axis in response to a combination of attractive and repulsive cues.

The series of molecular signals mediated by the serine/threonine kinase Hippo or one of its orthologs.
