Abstract:
Gliomas are the most common central nervous system tumors and account for 30% of all primary brain tumors, 80% of all malignant ones, and the vast majority of deaths that are caused by brain tumors. Among them, glioblastoma multiforme has the most aggressive and invasive course. Due to its heterogeneity, it is difficult to treat, and one of the reasons for this are glioma stem cells (GSCs). Therapies such as radiotherapy and chemotherapy are used to treat gliomas but do not bring the expected results. Therefore, treatments targeting glioma stem cells are emerging. A promising strategy is to target GSCs with natural compounds. This review aims to describe the problem of glioma stem cells, the treatment of gliomas, and therapies based on natural compounds, which are promising for the future.
Insights
Gliomas, aggressive brain tumors, are challenging to treat due to glioma stem cells (GSCs). Natural compounds offer a promising therapeutic strategy targeting these GSCs for improved outcomes.
Area of Science:
- Neuro-oncology
- Cancer Biology
- Pharmacology
Background:
- Gliomas represent the most common central nervous system tumors, constituting 30% of primary brain tumors and 80% of malignant ones.
- Glioblastoma multiforme is particularly aggressive, with its heterogeneity and the presence of glioma stem cells (GSCs) complicating treatment.
- Conventional therapies like radiotherapy and chemotherapy show limited efficacy against gliomas, highlighting the need for novel therapeutic approaches.
Purpose of the Study:
- To review the challenges associated with glioma stem cells (GSCs) in the context of glioma treatment.
- To explore current therapeutic strategies for gliomas, emphasizing their limitations.
- To highlight the potential of natural compounds as a targeted therapy for GSCs in future glioma treatment.
Main Methods:
- Literature review on glioma epidemiology and treatment.
- Analysis of the role of glioma stem cells (GSCs) in tumor progression and treatment resistance.
- Exploration of natural compounds with potential anti-GSC activity.
Main Results:
- Glioma stem cells (GSCs) are identified as a key factor in the resistance of gliomas to conventional therapies.
- Current treatments for gliomas, including radiotherapy and chemotherapy, often fail to eradicate GSCs, leading to tumor recurrence.
- Natural compounds demonstrate potential in targeting and eliminating GSCs, suggesting a promising avenue for novel therapeutic development.
Conclusions:
- Glioma stem cells (GSCs) present a significant therapeutic challenge in treating gliomas.
- Targeting GSCs is crucial for improving treatment outcomes in glioma patients.
- Natural compounds represent a promising and viable strategy for future glioma therapies, particularly for targeting GSCs.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
