Despite advances in treatment, challenges such as drug resistance limit the effectiveness of chemotherapy, including doxorubicin. Studies have shown that reserpine, a naturally occurring indole alkaloid, has anticancer properties in various malignancies. The aim of this study was to investigate whether reserpine increases the effectiveness of doxorubicin in hepatocellular carcinoma cells under in vitro conditions. Material and Methods: Human hepatocellular carcinoma (HepG2) cells were cultured. The IC50 value of reserpine was determined by the MTT method. Doxorubicin and reserpine were applied to HepG2 cells, both separately and in combination. DNA damage was evaluated by the alkaline comet assay. Results: Doxorubicin and reserpine significantly increased DNA damage in HepG2 cells when applied alone (p KW - Hepatocellular carcinoma KW - reserpine KW - doxorubicin KW - genotoxicity N2 - Amaç: Primer karaciğer maligniteleri arasında en sık tanı konulanı hepatosellüler karsinomdur. Tedavideki ilerlemelere rağmen, ilaç direnci gibi zorluklar doksorubisin dahil olmak üzere kemoterapilerin etkinliğini sınırlandırmaktadır. Yapılan çalışmalarda doğal olarak oluşan bir indol alkaloidi olan reserpinin çeşitli malignitelerde antikanser özellikler göstermiştir. Bu çalışmada amacımız, in vitro koşullarda reserpinin hepatosellüler karsinom hücrelerinde doksorubisinin etkinliğini artırıp artırmadığı araştırılmasıdır. Gereç ve Yöntemler: İnsan hepatosellüler kanser hücreleri (HepG2) kültüre edildi. Rezerpinin IC50 değeri MTT testi ile belirlendi. Doksorubisin ve reserpin HepG2 hücrelerine hem ayrı ayrı hem de birlikte uygulandı. DNA hasarı ise alkali comet testi ile değerlendirildi. Bulgular: Doksorubisin ve rezerpin tek başına uygulandığında HepG2 hücrelerinde DNA hasarını anlamlı düzeyde artırdı (p CR - Al-Bloushi S, Safer AM, Afzal M, Mousa SA.
