Journal Club: The Simplest Way to Lengthen Telomeres?

Lengthening telomeres with a simple supplement sounds almost too good to be true. Yet, two recent papers suggest that supplying cells with thymidine, a basic DNA building block, is enough to do just that. Join us as we explore the unexpected discovery, why it's a big deal for telomere biology, and the big question that remains: how does it actually work? (00:00) Intro (07:20) Why do we even need telomeres (14:30) The approach: CRISPR screen for telomere regulators (16:30) The core finding: More thymidine, longer telomeres (21:40) What makes these papers cool pt 1 (25:00) The missing piece: What's the mechanism? (29:50) What makes these papers cool pt 2 (33:30) Outro The papers: 1. Mannherz, W., Agarwal, S. Thymidine nucleotide metabolism controls human telomere length. Nat Genet 55, 568–580 (2023). 2.
