  2. Phylogenetic signal - Wikipedia

    en.wikipedia.org/wiki/Phylogenetic_signal

    Phylogenetic signal is a measure, closely related with an evolutionary process and development of taxa. It is thought that high rate of evolution leads to low phylogenetic signal and vice versa (hence, high phylogenetic signal is usually a consequence of either low rate of evolution either stabilizing type of selection). [3]

  3. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways [115] The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as ...

  4. cAMP-dependent pathway - Wikipedia

    en.wikipedia.org/wiki/CAMP-dependent_pathway

    It causes them to break apart from the catalytic sub-units. The catalytic sub-units make their way in to the nucleus to influence transcription. Further effects mainly depend on cAMP-dependent protein kinase, which vary based on the type of cell. cAMP-dependent pathway is necessary for many living organisms and life processes.

  5. Cyclic adenosine monophosphate - Wikipedia

    en.wikipedia.org/wiki/Cyclic_adenosine_monophosphate

    cAMP represented in three ways Adenosine triphosphate. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3',5'-cyclic adenosine monophosphate) is a second messenger, or cellular signal occurring within cells, that is important in many biological processes. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms ...

  6. Interleukin 8 - Wikipedia

    en.wikipedia.org/wiki/Interleukin_8

    IL-8 is the primary cytokine involved in the recruitment of neutrophils to the site of damage or infection; in a process called chemotaxis.A number of variables are essential for the successful chemotaxis of neutrophils, including the increased expression of high affinity adhesion molecules to secure the neutrophil to the endothelium near the affected site (and is therefore not washed away ...

  7. MAPK/ERK pathway - Wikipedia

    en.wikipedia.org/wiki/MAPK/ERK_pathway

    Bottom, signal enters the cell nucleus and causes transcription of DNA, which is then expressed as protein. The MAPK/ERK pathway (also known as the Ras-Raf-MEK-ERK pathway ) is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell.

  8. Hill equation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Hill_equation_(biochemistry)

    The Hill equation can be applied in modelling the rate at which a gene product is produced when its parent gene is being regulated by transcription factors (e.g., activators and/or repressors). [11] Doing so is appropriate when a gene is regulated by multiple binding sites for transcription factors, in which case the transcription factors may ...

  9. CDP-choline pathway - Wikipedia

    en.wikipedia.org/wiki/CDP-choline_pathway

    Structures and localization of the enzymes in the CDP-choline pathway. [1]: 415 The CDP-choline pathway, first identified by Eugene P. Kennedy in 1956, is the predominant mechanism by which mammalian cells synthesize phosphatidylcholine (PC) for incorporation into membranes or lipid-derived signalling molecules.
