Abstract:
With tendency to invade rapidly in the brain, malignant gliomas are very resistant to conventional therapies including radiation and chemotherapy. Recent advances in genetic and molecular techniques have made it possible to define characteristic molecular profiles of malignant gliomas. Based on the list of the molecules closely related to glioblastoma tissues, we reviewed strategies targeting them. Target molecules extensively studied include EGFR, PTEN, telomerase and signal pathway modulators for Ras/Raf/MAPK and PI3K/Akt/mTOR pathways. Therapies targeting specific molecules may result in killing tumor cells effectively while keeping normal cells intact.
Insights
Malignant gliomas are resistant to standard treatments. Targeting specific molecules like EGFR and pathways such as PI3K/Akt/mTOR offers a promising approach for effective cancer therapy with reduced side effects.
Area of Science:
- Neuro-oncology
