Apoptosis, a form of programmed cell death, is a critical component in maintaining homeostasis and growth in all tissues and plays a significant role in immunity and cytotoxicity. In contrast to necrosis or traumatic cell death, apoptosis is a well-controlled and vital process characterized mainly by cytoplasmic shrinkage, chromatin condensation, DNA fragmentation, membrane blebbing and apoptotic bodies. Our understanding of apoptosis is partly based on observations in invertebrates but mainly in mammals.

Metrics details. Programmed cell deaths in the nematode Caenorhabditis elegans are generally considered suicides. Dying cells are engulfed by neighboring cells in a process of phagocytosis. To better understand the interaction between the engulfment and death processes, we analyzed B. We found that B.

Programmed cell death during animal development.

Apoptosis, a form of programmed cell death, is a critical component in maintaining homeostasis and growth in all tissues and plays a significant role in immunity and cytotoxicity. In contrast to necrosis or traumatic cell death, apoptosis is a well-controlled and vital process characterized mainly by cytoplasmic shrinkage, chromatin condensation, DNA fragmentation, membrane blebbing and apoptotic bodies.

Our understanding of apoptosis is partly based on observations in invertebrates but mainly in mammals.

Despite the great advantages of fish models in studying vertebrate development and diseases and the tremendous interest observed in recent years, reports on apoptosis in fish are still limited. Although apoptotic machinery is well conserved between aquatic and terrestrial organisms throughout the history of evolution, some differences exist in key components of apoptotic pathways. Core parts of apoptotic machinery in fish are virtually expressed as equivalent to the mammalian models.

Some differences are, however, evident, such as the extrinsic and intrinsic pathways of apoptosis including lack of a C-terminal region in the Fas-associated protein with a death domain in fish. Aquatic species inhabit a complex and highly fluctuating environment, making these species good examples to reveal features of apoptosis that may not be easily investigated in mammals. Therefore, in order to gain a wider view on programmed cell death in fish, interactions between the main environmental factors, chemicals and apoptosis are discussed in this review.

It is indicated that apoptosis can be induced in fish by exposure to environmental stressors during different stages of the fish life cycle.

Death Receptor Signaling

Programmed cell death PCD is the physiological death of a cell mediated by an intracellular suicide program. Although key components of the PCD execution pathway have been identified, how PCD is regulated during development is poorly understood. Here, we report that the epidermal growth factor EGF -like ligand LIN-3 acts as an extrinsic signal to promote the death of specific cells in Caenorhabditis elegans. LIN-1 binds to, and activates transcription of, the key pro-apoptotic gene egl-1 , which leads to the death of specific cells. Programmed cell death PCD is an evolutionarily conserved cellular process that is important for metazoan development and homeostasis. The epidermal growth factor EGF promotes cell proliferation, differentiation and survival during animal development.

Accordingly, death was thought to be inflicted and the cells to behave passively. The notion of cell death was revolutionised when it was discovered that it could also occur through an active biological process suicide, self-destruction. This type of cell death was initially described by three British scientists Kerr, Curie and Wyllie who named the process "Apoptosis". Apoptosis can be distinguished from necrosis by a number of morphologic and molecular features. The phenomenon was first identified in mammalian tissues in vivo, then in cell cultures. However, the concept itself gained considerable credit when modern techniques including molecular biology showed that like cell proliferation and differentiation, Apoptosis is a genetically controlled general biological phenomenon occurring in nematodes, plants and even in unicellular organisms. Several elements contribute to make Apoptosis and programmed Cell Death a phenomenon of major importance: 1.

Evolution of the Animal Apoptosis Network

Last reviewed: January Programmed cell death triggered by extracellular signals or genetically determined events and carried out by physiological processes within the cell. Apoptosis is one of the major forms of cell death in multicellular organisms necrosis is the other form. Also referred to as programmed cell death, apoptosis is defined by specific changes in cell morphology, followed by the engulfment of the cell corpse by phagocytes Fig. Often, the death of certain cells through apoptosis enhances the overall health of an individual.

The number of available eukaryotic genomes has expanded to the point where we can evaluate the complete evolutionary history of many cellular processes. Such analyses for the apoptosis regulatory networks suggest that this network already existed in the ancestor of the entire animal kingdom Metazoa in a form more complex than in some popular animal model organisms. This supports the growing realization that regulatory networks do not necessarily evolve from simple to complex and that the relative simplicity of these networks in nematodes and insects does not represent an ancestral state, but is the result of secondary simplifications.

View in English? Death receptor ligands characteristically initiate signaling via receptor oligomerization, which in turn results in the recruitment of specialized adaptor proteins and activation of caspase cascades. Caspase-8 then oligomerizes and is activated via autocatalysis. Activated caspase-8 stimulates apoptosis via two parallel cascades: it can directly cleave and activate caspase-3, or alternatively, it can cleave Bid, a pro-apoptotic Bcl-2 family protein.

The formation of the hand during embryogenesis, the peeling of sunburned skin and the tremor associated with Parkinson's disease all result from a common process: cell death. Cell death occurs throughout the life span of the organism and represents the ultimate differentiative decision made by cells.
