Background/Objective: The present work evaluates the antitumoral potential of essential oil extracted from Decatropis bicolor, a native plant of Mexico, with a focus on its ability to induce apoptosis in AGS cells, an experimental model for gastric adenocarcinoma. The purpose of the study is to elucidate the molecular mechanisms underlying intrinsic and extrinsic apoptotic pathways. Materials and Methods: A multifaceted approach was used, integrating a litteration investigation, hydrodistillation for essential oil extraction, molecular docking analysis to assess ligand-receptor interactions and cell culture experiments. Western Blot analysis was used to quantify the expression of key proteins involved in the apoptotic cascade. Results: The findings revealed significant activation of programmed cell death pathways, supporting the hypothesis that the essential oil of Decatropis bicolor acts as a promising antitumoral agent. These results open up new perspectives for the development of innovative therapeutic strategies for the treatment of gastric cancer.
Contesto/Obiettivo: Il presente lavoro valuta il potenziale antitumorale dell’olio essenziale estratto da Decatropis bicolor, una pianta nativa del Messico, con particolare attenzione alla sua capacità di indurre apoptosi nelle cellule AGS, un modello sperimentale di adenocarcinoma gastrico. Lo scopo dello studio è quello di chiarire i meccanismi molecolari alla base delle vie apoptotiche intrinseche ed estrinseche. Materiali e metodi: È stato utilizzato un approccio multiforme che ha integrato un’indagine sulla litterazione, l’idrodistillazione per l’estrazione dell’olio essenziale, l’analisi di docking molecolare per valutare le interazioni ligando-recettore ed esperimenti di coltura cellulare. L’analisi Western Blot è stata utilizzata per quantificare l’espressione di proteine chiave coinvolte nella cascata apoptotica. Risultati: i risultati hanno rivelato una significativa attivazione della cascata apoptotica programmata. I risultati hanno rivelato una significativa attivazione delle vie di morte cellulare programmata, supportando l’ipotesi che l’olio essenziale di Decatropis bicolor agisca come promettente agente antitumorale. Questi risultati aprono nuove prospettive per lo sviluppo di strategie terapeutiche innovative per il trattamento del cancro gastrico.
