[Poly-(ADP ribose) synthesis and regulation disorders in disease]
Abstract:
Poly(ADP-ribose) is a polyanion involved in the regulation of the DNA metabolism of cells. DNA repair, semiconservative DNA-synthesis, differentiation- and trans-formation functions are connected to changes in the activity of the poly(ADP-ribose)-polymerase. The incidence of most cancers shows a steady increase with age while the PAR-synthesis decreases linear in certain cells with age. In some diseases abnormalities could be detected in PAR-synthesis and binding to nuclear proteins.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
