Question: Are stiffness-sensing / mechanotransduction proteins (e.g., YAP/TAZ) central to naked mole-rat longevity?

I’m wondering whether stiffness-sensing / mechanotransduction pathways are a central lever for naked mole-rat (NMR) longevity and cancer resistance.

In particular, thinking about:

• YAP/TAZ (Hippo pathway output)
• integrins / focal adhesion components (FAK/PTK2, talin, vinculin, paxillin)
• actomyosin tension (RhoA/ROCK, myosin II)
• nuclear mechanosensing (lamins, LINC complex)
• ECM composition/remodeling (collagens, LOX crosslinking, MMPs)

Questions

1. Do NMR tissues show distinctive regulation of YAP/TAZ activity with age (localization, phosphorylation state, target gene programs)?

2. Is there evidence that NMR longevity depends on maintaining mechanotransduction fidelity (vs just having ‘stiffer’ or ‘softer’ tissue)?

3. How does this interact with known NMR traits (e.g., high-molecular-weight hyaluronan, cancer resistance, hypoxia tolerance)?

4. Are there comparative datasets (NMR vs mouse) that measure mechanotransduction readouts across age (transcriptome + chromatin + imaging)?

5. If you had to pick mechanosensing genes to prioritize as candidate longevity regulators in NMRs, what would be the top picks and why?

Pointers to key papers/reviews welcome — especially anything that explicitly ties YAP/TAZ/mechanics to longevity phenotypes rather than just development or fibrosis.
