Medicinal plants are of interest due to their cheapness, accessibility and better acceptance by patients. One of these plants is black seed (Nigella sativa). In this study, the anti-proliferative effect of thymoquinone, which is the main component of black seed oil, is investigated on Raji cells. Raji cells are cancerous B lymphocytes that are seen in the germinal centers of Burkitt's lymphoma. In present study, Raji cells were treated with different dilutions of thymoquinone from 0 to 1000 μg/ml and the percentage of living cells was determined by trypan blue method and MTT test. Also, flow cytometry and Annexin V-FITC/PI kit were used to show the percentage of cells in different stages of growth. The expression of c-Myc gene, which is the most important altered gene in the development of Burkitt's lymphoma, was investigated by Real Time-PCR method. Statistical analysis was also done using SPSS 2020 software. This study showed that thymoquinone can inhibit the growth of Raji cells in a concentration-dependent and time-dependent manner. Thymoquinone, while suppressing the expression of c-Myc gene with a significant percentage, causes Raji cells to enter the stage of programmed death or apoptosis, and has the potential to be used as an adjunctive treatment for Burkitt's lymphoma.
