Autophagy activity contributes to programmed cell death in Caenorhabditis elegans.
The physiological relationship between autophagy and programmed cell death during C. elegans development is poorly understood. In C. elegans, 131 somatic cells and a large number of germline cells undergo programmed cell death. Autophagy genes function in the removal of somatic cell corpses during embryogenesis. Here we demonstrated that autophagy activity participates in germ-cell death induce...
متن کاملA Novel Autophagy Regulatory Mechanism that Functions During Programmed Cell Death: A Dissertation
Autophagy is a cellular process that delivers cytoplasmic materials for degradation by the lysosomes. Autophagy-related (Atg) genes were identified in yeast genetic screens for vehicle formation under stress conditions, and Atg genes are conserved from yeast to human. When cells or animals are under stress, autophagy is induced and Atg8 (LC3 in mammal) is activated by E1 activating enzyme Atg7....
متن کاملProgrammed cell death in Dictyostelium.
Programmed cell death (PCD) of Dictyostelium discoideum cells was triggered precisely and studied quantitatively in an in vitro system involving differentiation without morphogenesis. In temporal succession after the triggering of differentiation, PCD included first an irreversible step leading to the inability to regrow at 8 hours. At 12 hours, massive vacuolisation was best evidenced by confo...
متن کاملApoptosis: programmed cell death.
C urrently there is much interest and excitement in the understanding of how cells undergo the process of apoptosis or programmed cell death. Understanding how, why, and when cells are instructed to die may provide insight into the aging process, autoimmune syndromes, degenerative diseases, and malignant transformation. This review focuses on the development of apoptosis and describes the proce...
متن کاملProgrammed cell death.
Programmed cell death is an integral component of C. elegans development. Genetic studies in C. elegans have led to the identification of more than two dozen genes that are important for the specification of which cells should live or die, the activation of the suicide program, and the dismantling and removal of dying cells. Molecular and biochemical studies have revealed the underlying conserv...
