Implication
Narrative review uncovers molecular mechanisms regulating telomerase in human cells, highlighting therapeutic opportunities for antiaging and anticancer interventions.
Key Points
- To review the structural components of the human telomerase complex and detail the molecular mechanisms governing its regulation during development, aging, and oncogenesis.
- Synthesized molecular evidence on the composition and function of the human telomerase ribonucleoprotein reverse transcriptase complex.
- Evaluated regulatory pathways controlling telomerase activity during normal human ontogeny and malignant transformation.
- Telomerase functions as a specialized RNA-dependent DNA polymerase that maintains linear chromosome ends, driving genome stability and cellular immortalization.
- Telomerase expression is strictly repressed in most somatic tissues during development but reactivated in tumors, establishing its dual relevance as an antiaging and anticancer target.
