• cellular stress
  2 December 2003

  Stress to the cell causes protein denaturation: the protein molecule loses its native functional conformation when it unfolds. Chaperones assist the damaged molecule to regain its functional conformation.
  If cellular stress proceeds unchecked by such antistress mechanisms as the protein-refolding action of chaperones, intracellular proteins become denatured and insoluble.
  These denatured proteins tend to stick to one another, precipitate, and form inclusion bodies. The development of (...)

• RNA silencing
  24 May 2005

  Definition: Small non-coding RNAs have rapidly emerged as important contributors to gene regulation. To carry out their biological functions, these small RNAs require a unique class of proteins called Argonautes.
  RNA silencing was discovered in plants as a mechanism whereby invading nucleic acids, such as transgenes and viruses, are silenced through the action of small (20-26 nt) homologous RNA molecules.
  Endogenous silencing pathways have important roles in gene regulation at the (...)

• S-nitrosylation
  14 April 2004

  S-nitrosylation is a ubiquitous redox-related modification of cysteine thiol by nitric oxide (NO), which transduces NO bioactivity. Accumulating evidence suggests that the products of S-nitrosylation, S-nitrosothiols (SNOs), play key roles in human health and disease.
