Aim:In our study, we aimed to investigate the effects of SAC on C6 glioblastoma cells and its antiproliferative and apoptotic effects on two- and three-dimensional cell culture systems.Material and Methods:The rat glioma cell line C6 was separated into 2D-Control, 2D-SAC, 3D-CMC-Control and 3D-CMC-SAC groups. While control cells were incubated under standard culture conditions, cells in the SAC groups were incubated with the IC50 dose (50 µM for both the 2D-SAC C6 and 3D-CMC-SAC groups) of SAC in culture medium for 24 and 48 hours. Thereafter, all groups were stained with antibodies recognizing NOTCH1 and JAGGED1, and the mRNA expression levels of NOTCH1 and JAGGED1 were evaluated by qRT-PCR.Results:Increasing doses of SAC were administered for 24 hours in the C6 glioma cell line. The concentration of 50 μM was chosen as the most suitable dose for administration. The gene expression profiles were different in the two forms of culture. NOTCH1 receptor mRNA expression levels were significantly decreased in cells treated with 50 μM SAC for 24 hours compared to control cells in both the two-dimensional (2D) and three-dimensional (3D) cell cultures. The immunoreactivities of both of these markers (JAGGED1 and NOTCH1) were significantly decreased in the glioma cells in the SAC group compared to the control group.Conclusion:This study shows that SAC has potential as a drug for human use, as indicated by its nontoxic nature. The present study confirmed the anticancer activity of SAC by modulating NOTCH1 and JAGGED1 signaling in glioma cancer cells.
