PubMed 39126110 · doi:10.3390/ijms25158542
What was done
This narrative review summarizes literature regarding the mechanistic links connecting telomere dynamics, telomerase activity, cellular aging, inflammation, and oncogenesis, as well as therapeutic approaches utilizing telomerase inhibition.
What was found
The abstract reports no quantitative data or numerical outcomes. It describes qualitative biological interactions: replication-driven telomere shortening limits tumor growth but can induce oncogenic chromosomal instability. Cancer cells express telomerase to prevent critical shortening and utilize telomerase in alternative growth-promoting pathways. Additionally, inflammation accelerates telomere dysfunction, while telomere elements contribute to modulating inflammatory responses.
Why it matters
The paper outlines how the intersection of telomere maintenance, inflammation, and cellular senescence contributes to tumor progression, providing context for telomerase-targeted anticancer strategies.
Limits
As a narrative review, the paper presents no original experimental or clinical data and does not employ systematic review methods. No sample sizes, effect estimates, or quantitative metrics are reported in the abstract.
