Abstract (original English)

Olive polyphenols, including oleacein, oleocanthal, and oleuropein, have demonstrated potential benefits in mitigating the risk of metabolic diseases such as obesity and inflammation by improving glycemic control, reducing blood pressure, and lowering inflammation. This study provides a comprehensive comparative analysis of these compounds using human adipose-derived stem cells (hASCs). Whole-transcriptome analysis was employed to investigate the compounds' effects on adipocytes, focusing on immune system and metabolic pathways. A protein-protein interaction (PPI) network identified key targets and pathways. Oleacein uniquely enriched the PI3K-AKT pathway and demonstrated distinct regulation of inflammation and metabolism. The PPI network pinpointed growth hormone receptor (GHR) and interleukin-6 receptor (IL6R) as significant targets. Quantitative RT-qPCR analysis showed that oleacein significantly increased IL6R expression, while oleocanthal and oleuropein had no effect. GHR expression was also elevated by oleacein, although without statistical significance. Physicochemical properties of the compounds were analyzed for drug development potential. Molecular docking simulations indicated superior binding affinities for oleacein with GHR and IL6R, supported by surface plasmon resonance (SPR) assays, which confirmed stable interactions with both receptors. This study is the first
