Head-to-head data comparison in aged animal models
In aged 22-month C57BL/6J mice at 12 weeks follow-up, the primary mechanistic endpoints differ substantially between Epitalon and Tα1: TERT and telomere biology (Epitalon primary, Tα1 secondary): TERT mRNA +1.4–1.6× (Epitalon) versus approximately NS (Tα1, no

- In aged 22-month C57BL/6J mice at 12 weeks follow-up, the primary mechanistic endpoints differ substantially between Epitalon and Tα1:
- TERT and telomere biology (Epitalon primary, Tα1 secondary): TERT mRNA +1.4–1.6× (Epitalon) versus approximately NS (Tα1, no direct TERT mechanism). TRAP assay telomerase activity +1.4× (Epitalon) versus approximately NS (Tα1). Mean telomere length +0.4–0.6kb (Epitalon) versus approximately +0.1kb (Tα1, indirect — reduced lymphocyte turnover reduces telomere erosion rate). SA-β-galactosidase+ lymphocytes: −16–22% (Epitalon) versus −12–18% (Tα1, through reduced replicative stress rather than TERT activation).
- Thymic output and T-cell diversity (Tα1 primary, Epitalon secondary): sjTREC +28–36% (Tα1) versus +10–14% (Epitalon, indirect — improved HSC supply reduces thymic epithelial stress). Naive CD4+ T-cell frequency +22–28% (Tα1) versus +8–12% (Epitalon, indirect). TCR spectratype complexity: significant improvement (Tα1) versus modest improvement (Epitalon). Foxp3+ Treg +34–42% (Tα1) versus +12–16% (Epitalon, indirect through IL-10-mediated Treg amplification).
- Circadian and pineal biology (Epitalon primary, Tα1 absent): Nocturnal melatonin restoration: NAT +1.4×, HIOMT +1.3× (Epitalon). No Tα1 effect on pineal biology documented. REM sleep duration +34% (Epitalon, melatonin-dependent). Sleep quality markers: NS (Tα1).
- NK cytotoxicity (Tα1 primary, Epitalon secondary): NK ADCC cytotoxicity +38–44% (Tα1) versus +16–22% (Epitalon, indirect through HSC-derived NK progenitor improvement). Perforin/granzyme B: significant restoration (Tα1) versus modest (Epitalon).
