  2. Akt/PKB signaling pathway - Wikipedia

    en.wikipedia.org/wiki/Akt/PKB_signaling_pathway

    One of the ways the pathway is negatively regulated is by reducing PIP 3 levels. Phosphatase and tensin homolog (PTEN) antagonises PI3K by converting PI(3,4,5)P 3 into PI(4,5)P 2 . Loss of PTEN function leads to over-activation of Akt and is common in cancer cells (PTEN is a tumour suppressor ).

  3. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    At the end, the end of a signal pathway leads to the regulation of a cellular activity. This response can take place in the nucleus or in the cytoplasm of the cell. A majority of signaling pathways control protein synthesis by turning certain genes on and off in the nucleus. [45]

  4. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    Another example, sonic hedgehog signaling pathway, is one of the key regulators of embryonic development and is present in all bilaterians. [2] Signaling proteins give cells information to make the embryo develop properly. When the pathway malfunctions, it can result in diseases like basal cell carcinoma. [3]

  5. Biological pathway - Wikipedia

    en.wikipedia.org/wiki/Biological_pathway

    In cell biology, a biological pathway is a series of interactions among molecules in a cell that leads to a certain product or a change in the cell. Such a pathway can trigger the assembly of new molecules, such as a fat or protein. Pathways can also turn genes on and off, or spur a cell to move. [1]

  6. Cell cycle checkpoint - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle_checkpoint

    In eukaryotes, the cell cycle consists of four main stages: G 1, during which a cell is metabolically active and continuously grows; S phase, during which DNA replication takes place; G 2, during which cell growth continues and the cell synthesizes various proteins in preparation for division; and the M phase, during which the duplicated ...

  7. Pathway analysis - Wikipedia

    en.wikipedia.org/wiki/Pathway_analysis

    Pathway resources and types of pathway analysis using databases like KEGG, Reactome and WikiPathways. [1]Pathway is the term from molecular biology for a curated schematic representation of a well characterized segment of the molecular physiological machinery, such as a metabolic pathway describing an enzymatic process within a cell or tissue or a signaling pathway model representing a ...

  8. Biochemical switches in the cell cycle - Wikipedia

    en.wikipedia.org/wiki/Biochemical_switches_in...

    The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases. The phases include the G1 and G2 phases, DNA replication or S phase, and the actual process of cell division, mitosis or M phase. [1]

  9. Intracellular transport - Wikipedia

    en.wikipedia.org/wiki/Intracellular_transport

    Prokaryotes are able to subsist by allowing materials to enter the cell via simple diffusion. Intracellular transport is more specialized than diffusion; it is a multifaceted process which utilizes transport vesicles. Transport vesicles are small structures within the cell consisting of a fluid enclosed by a lipid bilayer that hold cargo. These ...
