Abstract:
The treatment of glioblastoma remains a major challenge for clinicians since these highly aggressive brain tumors are relatively resistant towards radio- and chemotherapy. The pathways that control apoptosis are altered in glioblastoma cells leading to resistance towards apoptotic stimuli in general. In this review we describe the alterations affecting the p53 pathway, the BCL-2 protein family, the inhibitor of apoptosis proteins and several growth factor pathways involved in the regulation of programmed cell death and define possible targets for new therapies within these apoptotic pathways in glioblastomas. Moreover, we review strategies to target death receptor pathways, most notably to render the glioblastoma cells more susceptible towards this approach without enhancing toxicity in general. Most of the strategies targeting apoptosis in glioblastomas presented here are in a pre-clinical stage of development, however, they all share the ultimative goal to improve the outcome for glioblastoma patients.
Insights
Glioblastoma treatment is challenging due to resistance to therapies. This review explores targeting apoptosis pathways, like p53 and BCL-2, to improve glioblastoma patient outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Glioblastoma is a highly aggressive brain tumor with significant resistance to conventional radio- and chemotherapy.
- Altered apoptosis pathways in glioblastoma cells contribute to their resistance against apoptotic stimuli.
Purpose of the Study:
- To review alterations in key apoptosis-regulating pathways in glioblastoma.
- To identify potential therapeutic targets within these pathways for glioblastoma treatment.
- To explore strategies for enhancing glioblastoma cell susceptibility to death receptor-mediated apoptosis.
Main Methods:
- Review of scientific literature on glioblastoma apoptosis pathways.
- Analysis of alterations in the p53 pathway, BCL-2 protein family, and inhibitor of apoptosis proteins.
- Examination of growth factor pathways regulating programmed cell death.
- Evaluation of strategies targeting death receptor pathways.
Main Results:
- Specific alterations in the p53 pathway, BCL-2 family, and IAP proteins contribute to glioblastoma's apoptotic resistance.
- Several pre-clinical strategies targeting apoptosis pathways show promise for glioblastoma therapy.
- Targeting death receptor pathways may sensitize glioblastoma cells without increasing general toxicity.
Conclusions:
- Targeting apoptosis pathways represents a promising therapeutic avenue for glioblastoma.
- Further research and development of these pre-clinical strategies are crucial for improving glioblastoma patient outcomes.
- Modulating programmed cell death mechanisms offers a potential strategy to overcome therapeutic resistance in glioblastoma.
