Area of Science:

  • Gerontology and pharmacology
  • Molecular biology and biochemistry

Background:

  • Aging poses significant risks to human health and quality of life.
  • Developing novel anti-aging interventions is crucial for delaying age-related diseases.

Purpose of the Study:

  • To investigate the anti-aging and antioxidative effects of salidroside (SA).
  • To elucidate the molecular mechanisms underlying SA's action, focusing on its interaction with heat shock protein 90 (HSP90).

Main Methods:

  • Utilized computer-assisted methods and label-free interaction analysis.
  • Performed in vitro assays to assess SA's binding affinity and functional impact on HSP90.
  • Investigated downstream gene expression and cellular responses to oxidative stress.

Main Results:

  • Salidroside (SA) significantly prolonged lifespan and demonstrated anti-aging and antioxidative properties.
  • SA directly binds to heat shock protein 90 (HSP90).
  • SA inhibits HSP90 ATPase activity, altering protein interactions and gene expression to regulate lifespan and oxidative stress.

Conclusions:

  • Salidroside (SA) exerts anti-aging effects by modulating HSP90 activity and downstream pathways.
  • SA shows promise as a potential therapeutic agent for combating aging and age-related conditions.
  • These findings offer new insights into the pharmacological applications of SA across different species.
