• genomic stability
  13 July 2003

  A fundamental axiom of genetic inheritance is a requirement for exceptional genetic stability over many generations of cells and organisms. However, cells have to contend with both intracellular and extracellular environments that constantly challenge the chemical stability of the genome.
  Additionally, although normal metabolic transactions of DNA such as replication, recombination and repair are generally highly accurate, there are limits to the fidelity of these processes, so genomic (...)

• phagocytosis
  23 April 2004

  Definition: Phagocytosis is a specific form of endocytosis involving the vesicular internalization of solid particles, such as bacteria. It is therefore distinct from other forms of endocytosis such as pinocytosis, the vesicular internalization of various liquids, and recptor-dependent endocytosis.
  Phagocytosis (literally, cell-eating) is the process by which cells ingest large objects, such as cells which have undergone apoptosis, bacteria, or viruses. The membrane folds around the (...)

• cell-matrix adhesion
  14 March 2004

  Cell-matrix adhesions involve transmembrane glycoproteins such as cell adhesion molecules and integrins, which are thought to function via interactions of their cytoplasmic domains with proteins associated with the cytoskeleton, as vinculin (VCL) or talins (TLNs: TLN1 and TLN2).

• cellular aging
  7 March 2004

  Cellular aging is the result of a progressive decline in the proliferative capacity and life span of cells and the effects of continuous exposure to exogenous influences that result in the progressive accumulation of cellular and molecular damage. Structural and Biochemical Changes with Cellular Aging
  A number of cell functions decline progressively with age.
  Oxidative phosphorylation by mitochondria is reduced, as is synthesis of nucleic acids and structural and enzymatic proteins, (...)
