Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Programmed cell death (PCD; sometimes referred to as cellular suicide [1]) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. [2] [3] PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle.
John Foxton Ross Kerr AO (24 January 1934 – 4 June 2024) was an Australian pathologist.He was the first to describe the ultrastructural changes in apoptosis, and could show that they differ significantly from the changes that occur in necrosis, another form of cell death.
Nofriansyah Yosua Hutabarat was born on 29 November 1994 in Jambi, Indonesia, to Samuel Hutabarat (born 1966) and Rosti Simanjuntak (born 1968). [7] He has an older sister, Yuni Artika Hutabarat (born 1988), and a younger brother, Mahareza Rizky Hutabarat (born 2000).
Cell growth plays a crucial role in cell proliferation, regulating cellular homeostasis and cell cycle progression through dynamic changes in cell size. [1] And like DNA damage, it can promote senescence by triggering a prolonged cell cycle arrest. [5]
William McChord Hurt [1] [2] (March 20, 1950 – March 13, 2022) was an American actor. For his performances on stage and screen, he has received various awards including an Academy Award, a British Academy Film Award, and a Cannes Film Festival Award for Best Actor, in addition to nominations for five Golden Globe Awards, two Primetime Emmy Awards, and a Tony Award.
The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
Chromaffin cells, also called pheochromocytes (or phaeochromocytes), are neuroendocrine cells found mostly in the medulla of the adrenal glands in mammals.These cells serve a variety of functions such as serving as a response to stress, monitoring carbon dioxide and oxygen concentrations in the body, maintenance of respiration and the regulation of blood pressure.
