Abstract

Rg1 significantly improved spatial learning and memory in aging mice.

  • Chemically induced aging in mice was achieved through D-galactose and AlCl administration.
  • Performance improvements were observed in step down avoidance tests and Morris water maze experiments.
  • Rg1 restored the decline of FGF2 and BDNF levels associated with aging.
  • Reactivation of the TrkB/Akt signaling pathways in the hippocampus and prefrontal cortex was noted.
  • Rg1 antagonistically restored the expression of the anti-apoptotic protein Bcl-2 and the apoptosis-promoting enzyme cleaved-Caspase3.
