Programmed Cell Death in Unicellular Phytoplankton
Unicellular, planktonic, prokaryotic and eukaryotic photoautotrophs (phytoplankton) have an ancient evolutionary history on Earth during which time they have played key roles in the regulation of marine food webs, biogeochemical cycles, and Earth's climate. Since they represent the basis of aquatic ecosystems, the manner in which phytoplankton die critically determines the flow and fate of phot...
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 کامل[Apoptosis--programmed cell death].
Apoptosis is a highly organized physiologic mechanism of destroying injured and abnormal cells as well as maintaining homeostasis in the multicellular organism. Apoptosis is tightly controlled at the genetic level and dysregulation of the apoptosis machinery may contribute to a variety of diseases. Pharmacologic manipulation of this pathway is a novel therapeutic target.
متن کاملThe Meaning of Death: Evolution and Ecology of Apoptosis in Protozoan Parasites
The discovery that an apoptosis-like, programmed cell death (PCD) occurs in a broad range of protozoan parasites offers novel therapeutic tools to treat some of the most serious infectious diseases of humans, companion animals, wildlife, and livestock. Whilst apoptosis is an essential part of normal development, maintenance, and defence in multicellular organisms, its occurrence in unicellular ...
متن کاملApoptosis: a review of programmed cell death.
The process of programmed cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy-dependent biochemical mechanisms. Apoptosis is considered a vital component of various processes including normal cell turnover, proper development and functioning of the immune system, hormone-dependent atrophy, embryonic development and chemical-induced cell deat...
