摘要

Obesity remains a global health crisis, with limited therapeutic options for addressing metabolic dysfunction and inflammation. This study evaluates the therapeutic potential of Moringa Oleifera-loaded silver nanoparticles (MO-AgNPs) in modulating obesity-related biochemical and genetic markers. To optimize the synthesis of MO-AgNPs, Response Surface Methodology (RSM) using Design Expert software was employed to identify the optimal conditions for minimizing particle size, polydispersity index, and maximizing zeta potential. Male albino rats with high-carbohydrate, high-fat diet (HCHFD)-induced obesity were treated with AgNPs, Moringa Oleifera extract, or MO-AgNPs. Key assessments included biochemical markers, lipid profiles, adipokines, and the expression of thermogenic and metabolic genes (UCP1, PPARGC1A), along with histopathological evaluation of liver and pancreatic tissues. Transmission electron microscopy revealed spherical particles with an average size of approximately 40 nm, consistent with dynamic light scattering data. Treatment with MO-AgNPs significantly enhanced insulin sensitivity, improved lipid profiles, and regulated adipokine levels, while upregulating UCP1 and PPARGC1A expression more effectively than other treatments. Histological analysis demonstrated substantial restoration of liver and pancreatic tissue architecture, highlighting the protective effects of MO-AgNPs. Overall, MO-AgNPs represent an innovative therapeutic strategy, combining the bioactive properties of Moringa Oleifera with the enhanced functionality of silver nanoparticles, showing strong potential for addressing obesity and its associated metabolic complications.
