Epidemiological evidence confirms that plants are primary sources of drugs used to reduce the incidence of cancer and prevent cancer-related deaths. Sternbergia species are used for therapeutic purposes due to the amaryllidaceae alkaloids, lectins, phenolic acids, pigments, and volatile components they contain. In this study, the anticancer properties of S. lutea extracts were tested on the A375 malignant melonoma cell line. In addition, in the study, the transcriptional expression of BCL-XL and Cas9 genes, which function in cell proliferation and apoptotic pathways, in cells treated with plant extracts were determined by qRT-PCR. According to the cytotoxicity results made by the MTT test, the highest inhibition percentage was determined at the plant's concentration of 500 μg/𝑚L. At this concentration, A375 cells were inhibited by 83.63%, and the IC50 value of the extract was calculated as 194.64 μg/𝑚L. In addition, in qRT-PCR analyses, a statistically significant increase was observed in the mRNA expression levels of Cas9 genes, which are positively correlated with the apoptotic pathway, in the extract and cisplatin-applied groups compared to the control group.
