Autophagy, a highly conserved catabolic program for degrading proteins and organelles, is essential for cell and tissue homeostasis. Primarily, this process has a cytoprotective role under nutrient deprivation, but several stress stimuli can induce autophagy and, thus, distinct programmed cell death (PCD) pathways can be actived when stress is not abolished. Fish ovaries are a suitable experimental model system for studying the mechanisms of PCD due to the presence of postovulatory and atretic (i.e., non-ovulated) follicles, which follow different routes after spawning. Apoptosis of the follicular cells is the major mechanism responsible for the rapid resorption of the postovulatory follicles. Recently, we investigated the contribution of PCD during follicular atresia in two species of freshwater fish. In contrast to mammals, this study revealed that follicular apoptosis is not a major process for deletion of follicular cells in atretic follicles. Furthermore, we detected autophagic vacuoles containing degenerating organelles increasing through follicular atresia in both species. In this addendum, we propose a hypothesis for follicular cell removal during ovarian regression in oviparous fish. In this model, autophagy could have dual roles in follicular atresia. Thus, fish ovaries after breeding are suitable models for studying the interactions among the different cell death pathways.
