Description

The study demonstrates XSD increases AMPK and SIRT1 protein levels but doesn’t elucidate whether XSD compounds directly activate these proteins or work through upstream regulators. Understanding the precise molecular mechanism is crucial for optimizing therapeutic targeting and predicting drug interactions.
