  2. Turgor pressure - Wikipedia

    en.wikipedia.org/wiki/Turgor_pressure

    Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk). One mechanism in plants that regulate turgor pressure is the cell's ...

  3. Warburg hypothesis - Wikipedia

    en.wikipedia.org/wiki/Warburg_hypothesis

    Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria. [1]

  4. Causes of cancer - Wikipedia

    en.wikipedia.org/wiki/Causes_of_cancer

    Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]

  5. Warburg effect (oncology) - Wikipedia

    en.wikipedia.org/wiki/Warburg_effect_(oncology)

    In cancer cells, major changes in gene expression increase glucose uptake to support their rapid growth. Unlike normal cells, which produce lactate only when oxygen is low, cancer cells convert much of the glucose to lactate even in the presence of adequate oxygen. This is known as the “Warburg Effect.”

  6. Guard cell - Wikipedia

    en.wikipedia.org/wiki/Guard_cell

    Guard cells have cell walls of varying thickness(its inner region, adjacent to the stomatal pore is thicker and highly cutinized [7]) and differently oriented cellulose microfibers, causing them to bend outward when they are turgid, which in turn, causes stomata to open.

  7. Plasmolysis - Wikipedia

    en.wikipedia.org/wiki/Plasmolysis

    A plant cell in hypotonic solution will absorb water by endosmosis, so that the increased volume of water in the cell will increase pressure, making the protoplasm push against the cell wall, a condition known as turgor. Turgor makes plant cells push against each other in the same way and is the main line method of support in non-woody plant ...

  8. Carcinogenesis - Wikipedia

    en.wikipedia.org/wiki/Carcinogenesis

    The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).

  9. Immunoediting - Wikipedia

    en.wikipedia.org/wiki/Immunoediting

    Tumor cell debris produced as a result of tumor death is then ingested by dendritic cells, followed by the migration of these dendritic cells to the draining lymph nodes. The recruitment of more immune cells also occurs and is mediated by the chemokines produced during the inflammatory process.
