Programmed cell death in Hydra
Seminars in Cancer Biology, 2007Hydra is one of the simplest metazoans and thus an important model organism for studies on the evolution of developmental mechanisms in multi-cellular animals. In Hydra apoptosis is involved in the regulation of cell numbers in response to feeding, in regeneration and in the removal of non-self cells. It also participates in the maintenance of cellular

Programmed cell death in the germline
Seminars in Cell & Developmental Biology, 2005In many organisms, programmed cell death of germ cells is required for normal development. This often occurs through highly conserved events including the transfer of vital cellular material to the growing gametes following death of neighboring cells. Germline cell death also plays a role in such diverse processes as removal of abnormal or superfluous ...

Programmed Cell Death in Development
1995Although cell death has long been recognized to be a significant element in the process of embryonic morphogenesis, its relationships to differentiation and its mechanisms are only now becoming apparent. This new appreciation has come about not only through advances in the understanding of cell death in parallel immunological and pathological ...

Programmed cell death in trypanosomatids
Parasitology Today, 1997It has generally been assumed that apoptosis and other forms of programmed cell death evolved to regulate growth and development in multicellular organisms. However, recent work has shown that some parasitic protozoa have evolved a cell suicide pathway analogous to the process described as apoptosis in metazoa.

The biochemistry of programmed cell death
The FASEB Journal, 1995Programmed cell death (PCD) is involved in the removal of superfluous and damaged cells in most organ systems. The induction phase of PCD or apoptosis is characterized by an extreme heterogeneity of potential PCD‐triggering signal transduction pathways.

The machinery of programmed cell death
Pharmacology & Therapeutics, 2001Apoptosis or programmed cell death is an essential physiological process that plays a critical role in development and tissue homeostasis. However, apoptosis is also involved in a wide range of pathological conditions. Apoptotic cells may be characterized by specific morphological and biochemical changes, including cell shrinkage, chromatin ...

Erythrocyte programmed cell death
IUBMB Life, 2008AbstractEryptosis, the suicidal death of erythrocytes, is characterised by cell shrinkage, membrane blebbing and cell membrane phospholipid scrambling with phosphatidylserine exposure at the cell surface. Phosphatidylserine‐exposing erythrocytes are recognised by macrophages, which engulf and degrade the affected cells.

Programmed cell death in cell cultures
Plant Molecular Biology, 2000In plants most instances of programmed cell death (PCD) occur in a number of related, or neighbouring, cells in specific tissues. However, recent research with plant cell cultures has demonstrated that PCD can be induced in single cells. The uniformity, accessibility and reduced complexity of cell cultures make them ideal research tools to investigate ...

Programmed cell death and the caspases
APMIS, 1999Members of a family of cysteine proteases known as caspases orchestrate the intracellular biochemical events that enable animal cells to kill themselves by apoptosis. To counteract the apoptotic response to infection, some viruses have adapted and evolved proteins that specifically block caspases. More recently, it has been demonstrated that endogenous

Programmed cell death and cancer
Postgraduate Medical Journal, 2009Abstract Programmed cell death (PCD) is an important terminal pathway for cells of multicellular organisms, and is involved in a variety of biological events that include morphogenesis, maintenance of tissue homeostasis, and elimination of harmful cells.
