"The initiation of the activity of the inactive enzyme MAP kinase by phosphorylation by a MAPKK [goid 187] [pmid 10570282] [evidence TAS]; The process that regulates the coordinated growth and sprouting of blood vessels giving rise to the organized vascular system [goid 1569] [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 lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level [goid 1666] [pmid 15174142] [evidence IEP]; Cell migration that is accomplished by extension and retraction of a pseudopodium [goid 1667] [evidence IEA]; The characteristic movement of immature neurons from germinal zones to specific positions where they will reside as they mature [goid 1764] [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] [pmid 10942389] [evidence TAS]; The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis) [goid 6935] [pmid 10802710] [evidence TAS]; The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages [goid 6954] [pmid 8276799] [evidence TAS]; Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat [goid 6955] [pmid 10802710] [evidence TAS]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [evidence IEA]; The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand [goid 7186] [pmid 10644702] [evidence TAS]; Any process that increases the concentration of calcium ions in the cytosol [goid 7204] [pmid 10228019] [evidence TAS]; The process whose specific outcome is the progression of the immature germ cell over time, from its formation to the mature structure (gamete) [goid 7281] [evidence IEA]; The process whose specific outcome is the progression of the brain over time, from its formation to the mature structure. The brain is one of the two components of the central nervous system and is the center of thought and emotion. It is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.) [goid 7420] [evidence IEA]; The process by which the migration of an axon growth cone of a motor neuron is directed to a specific target site in response to a combination of attractive and repulsive cues [goid 8045] [evidence IEA]; The orderly movement of a germ cell, a cell specialized to produce haploid gametes, through the embryo from its site of production to the place where the gonads will form [goid 8354] [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 from a virus [goid 9615] [pmid 10583963] [evidence TAS]; The set of processes involved in the start of virus infection of cells [goid 19059] [pmid 12091904] [evidence EXP]; Any process that modulates the frequency, rate or extent of cell migration [goid 30334] [evidence IEA]; The expansion of a T cell population by cell division. Follows T cell activation [goid 42098] [evidence IEA]; Any process by which an organism has an effect on an organism of a different species [goid 44419] [evidence IEA]"
