Why does Metformin fail to delay CJD progression despite improving anti-aging hallmarks like Nano-PSO?

PARTIALLY ADDRESSED

Both compounds similarly reduced aging hallmarks (AMPK, Nrf2, COX IV1) and inflammation, yet only Nano-PSO delayed disease progression. This discordance challenges the assumption that anti-aging interventions are therapeutically equivalent and suggests unknown mechanistic differences critical for prion disease treatment. Gap type: contradiction Source paper: Comparing anti-aging hallmark activities of Metformin and Nano-PSO in a mouse model of genetic Creutzfeldt-Jakob Disease.
