A shared DNA methylation drift occurs with aging and tumorgenesis in the colon. Age-related inflammation and reduced Wnt signaling, which dysregulate iron metabolism and impair TET activity, drive this epigenetic drift.

Ferritin buffers intracellular iron and protects cells from iron toxicity. Yi et al. show that deleting the ferritin heavy chain (Fth1) impairs normal HSPC function but restricts AML progression and prolongs survival in mice.

When Ning, Francesca & Marc were selected to speak
@senescel.org 2025, they gave it their all, refining every argument and minute.
Their talks put our metabolic bottleneck model of aging on the field’s radar. 👏

What do you think drives tissue aging, the cell or its environment? 🤔

Lung cancer reprograms the bone marrow to its advantage.
Hedge et al. ( @miriammerad.bsky.social lab)
show that tumors trigger an NRF2-driven stress response in myeloid precursors, which then suppress anti-tumor immunity. Blocking NRF2 boosts immunotherapy.

200 years ago in Barcelona, your 40s meant preparing for death. Today, you might have 40 more years ahead.

But as @sjayolshansky et al. show, most gains came from reducing early death. Further progress depends on tackling aging and its consequences.
