Ribosomes and Ribosomal Proteins Promote Plasticity and Stemness Induction in Glioma Cells via Reprogramming

Area of Science:

• Neuro-oncology
• Cancer Biology
• Molecular Medicine

Background:

• Glioblastoma multiforme (GBM) is an aggressive adult brain tumor with poor patient survival despite current treatments.
• Genetic alterations in GBM are crucial for understanding its biology, but targeted therapies show limited efficacy.
• Chemo-radioresistance in GBM is a major challenge, often linked to stem-cell-like properties acquired through microenvironmental factors.

Purpose of the Study:

• To review recent literature and data on GBM aggressiveness.
• To explore the role of cellular reprogramming in GBM development and stem-cell-like phenotype acquisition.
• To discuss potential therapeutic strategies targeting GBM reprogramming.

Main Methods:

• Literature review of studies on Glioblastoma multiforme aggressiveness.
• Analysis of published data concerning GBM cell reprogramming and stem-cell phenotypes.
• Discussion of therapeutic options focusing on reprogramming mechanisms.

Main Results:

• Deregulation of ribosome biogenesis, including ribosomal protein S6, is implicated in cancer.
• Overexpression of ribosomal protein S6 and ribosome incorporation contribute to GBM cell reprogramming.
• These processes induce stem-cell-like phenotypes and enhance GBM aggressiveness.

Conclusions:

• Reprogramming of Glioblastoma multiforme cells, driven by factors like ribosomal protein S6, is key to their aggressiveness and stem-cell characteristics.
• Investigating and targeting GBM cell reprogramming presents a promising strategy to overcome chemo-radioresistance.
• Developing therapies that modulate reprogramming could improve patient survival and quality of life for GBM patients.
