Definitions
- telomeres Replication of a certain length of their telomeres, a phenomenon that was already recognized by atson in 1972 (atson in Nature New Biol. 233, 197-201 (1972)).
- the cumulative loss of telomeric DNA across many cell divisions is the reason for the limited replicative potential of somatic cells, while more than 85% of all human tumors reactivate an enzyme, telomerase, to compensate for the loss of telomeres and thus become immortal (see Shay and Bacchetti in European Journal of Cancer, 22, 787-791 (1997)).
- telomerase Human telomerase is a ribonucleoprotein (RNP) composed of at least one catalytic subunit (hTERT) and one RNA (hTR). Both components have been molecularly cloned and characterized.
- RNP ribonucleoprotein
- hTERT catalytic subunit
- hTR RNA
- Both components have been molecularly cloned and characterized.
- Biochemically, telomerase is a reverse transcriptase that uses a sequence section in hTR as a template to synthesize a strand of the telomeric DNA (Morin in Cell 5_9_, 521-529 (1989)).
- Methods of identifying telomerase activity as well as methods for the diagnosis and therapy of replicative senency and immortality by modulating the telomeres and telomerase have been described (Morin in Cell 5_2., 521-529 (1989); Kim et al. In Science £ 2 £,
- Inhibitors of telomerase can be used for tumor therapy since, unlike tumor cells, somatic cells are not dependent on telomerase.
