This newsletter presents a roundup of recent aging-research updates, framing studies on midlife hormonal intervention in mice and telomerase activity in hydra for readers curious about translational geroscience.
Key Takeaways
- Midlife ablation of the growth hormone receptor in mice produced an endocrine GH resistance signature and extended lifespan in both sexes.
- Male mice with midlife Ghr ablation showed improved insulin sensitivity despite increased adiposity and preserved neuromuscular and bone health.
- Hydra vulgaris expresses a telomerase catalytic subunit (hyTERT) in proliferative regions and shows sustained telomerase activity linked to negligible senescence.
