The paper identifies cis-regulatory elements controlling cellular senescence by performing CRISPR screens in human mesenchymal stromal cells, revealing a primate-specific SINE element that modulates P16INK4a and P15INK4b.

The paper identifies rare SIRT6 variants in centenarians that increase protein levels and delay cellular senescence, offering insights for geroprotective therapies.

This study shows that PNMA1 and PNMA4, derived from retrotransposons, are essential for reproductive capacity, as their absence leads to subfertility and hormonal changes in mice and associations with reproductive traits in humans.

The paper identifies a longevity-associated SMAD3 non-coding variant that impairs a cell-type specific enhancer, reducing inflammation and senescence in endothelial cells and improving healthspan in a mouse model.
