In vivo effects of resveratrol and 1,3-bis(2-chloroethyl)-1-nitrosurea combination on YKG1 glioblastoma cell line

İngilizce (OpenAlex)

Glioblastoma is a primary malignant brain tumor that can be treated with 1,3-bis(2-chloroethyl)-1-nitrosurea (BiCNU/carmustine). Resveratrol is a natural phenol that can interfere with apoptosis. This study aims to investigate how the combination of BiCNU and resveratrol affects glioblastoma cells in vitro. Accordingly, YKG1 glioblastoma cells were treated with different amounts of resveratrol (50 and 100 µM) and BiCNU (10 and 20 µM) either alone or in combination. Cell viability tests and immunochemical studies were conducted on these cells. According to results, increasing the amount of resveratrol and BiCNU decreased cell viability. Additionally, when these maximal doses of resveratrol and BiCNU (100 µM resveratrol plus 20 µM BiCNU) were applied, viability decreased to the highest cytotoxicity levels. Immunohistochemical analysis also revealed the significantly upregulated H scores of beclin-1 and caspase-3 in treated groups with the highest value in maximally combined concentration. These results indicated the cumulative effects of concurrent administration of BiCNU and resveratrol on the cytotoxicity of malignant human YKG1 glioblastoma cells in vitro.
