The hydrolysis of a peptide bond or bonds within a protein [goid 6508] [evidence IEA]; A form of programmed cell death induced by external or internal signals that trigger the activity of proteolytic caspases, whose actions dismantle the cell and result in cell death. Apoptosis begins internally with condensation and subsequent fragmentation of the cell nucleus (blebbing) while the plasma membrane remains intact. Other characteristics of apoptosis include DNA fragmentation and the exposure of phosphatidyl serine on the cell surface [goid 6915] [evidence IEA]; The process of regulating the proliferation and elimination of B cells such that the total number of B cells within a whole or part of an organism is stable over time in the absence of an outside stimulus [goid 1782] [evidence IEA]; The process by which cytochrome c is enabled to move from the mitochondrial intermembrane space into the cytosol, which is an early step in apoptosis and leads to caspase activation [goid 1836] [evidence IEA]; The cleavage of DNA during apoptosis, which usually occurs in two stages: cleavage into fragments of about 50 kbp followed by cleavage between nucleosomes to yield 200 bp fragments [goid 6309] [evidence IEA]; The hydrolysis of a peptide bond or bonds within a protein [goid 6508] [pmid 12888622] [evidence IDA]; A process that directly activates any of the steps required for cell death by apoptosis [goid 6917] [pmid 7983002] [evidence TAS]; The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood [goid 7507] [evidence IEA]; The series of events required for an organism to receive an auditory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Sonic stimuli are detected in the form of vibrations and are processed to form a sound [goid 7605] [evidence IEA];  [goid 8625] [evidence IEA]; The activation, by oxidative stress, of any of the steps required for cell death by apoptosis [goid 8631] [evidence IEA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an ultraviolet radiation (UV light) stimulus. Ultraviolet radiation is electromagnetic radiation with a wavelength in the range of 10 to 380 nanometers [goid 9411] [evidence IEA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to the organism [goid 9611] [evidence IEA]; The process whereby a relatively unspecialized cell acquires specialized features of a keratinocyte [goid 30216] [evidence IEA]; The breakdown of the nucleus into small membrane-bounded compartments, or blebs, each of which contain compacted DNA [goid 30264] [pmid 11350920] [evidence IMP]; Any process that stops, prevents or reduces the rate or extent of B cell proliferation [goid 30889] [evidence IEA]; The process of regulating the proliferation and elimination of T cells such that the total number of T cells within a whole or part of an organism is stable over time in the absence of an outside stimulus [goid 43029] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of cell death by apoptosis [goid 43066] [pmid 9353287] [evidence IGI]; The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field [goid 45165] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of CDK activity [goid 45736] [evidence IEA]; Any process that stops, prevents or reduces the rate or extent of activated T cell proliferation [goid 46007] [evidence IEA]; The process of apoptosis in neurons, the basic cellular unit of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the nervous system [goid 51402] [evidence IEA]
