Abstract
Objective: Glioblastoma multiforme (GBM), an aggressive
primary brain tumor, distinguished by an invasive growth
pattern and resistance to current therapeutic strategy. This study
investigates the potential of Oxypeucedanin (OP) as a natural
compound to induce apoptosis and inhibit proliferation in T98G
GBM cells, either alone or in combination with Temozolomide
(TMZ).
Materials and Methods: T98G cells were exposed to OP and TMZ
individually and in combination. Then, cell viability (MTT assay),
cell proliferation (using trypan blue), mRNA expression (qRTPCR), Cell cycle and apoptosis (flow cytometry), and migration
(wound healing assay) were evaluated.
Results: The viability assays revealed that both OP and less
potentially TMZ decreased cell viability in a time- and dosedependent manner. Notably, the combination of OP and TMZ
demonstrated synergistic effects, substantially enhancing apoptosis
rates while reducing proliferation, as evidenced by reduced cell
growth rates and altered cell cycle distribution towards G2/M arrest.
Additionally, gene expression analysis indicated increased Bax/Bcl2 ratios and decreased Ki-67 levels, suggesting enhanced apoptotic
susceptibility and lowered proliferation capacity. Furthermore, the
wound healing assay confirmed reduced migration in T98G cells,
particularly in the combination treatment group.
Conclusion: This study suggests the potential of OP as a
complementary therapeutic agent alongside TMZ for GBM
treatment.
