Abstract:
Glioblastoma multiforme (GBM) is the deadliest form of brain tumors. To date, the GBM therapeutical approach consists of surgery, radiation-therapy and chemotherapy combined with molecules improving cancer responsiveness to treatments. In this review, we will present a brief overview of the GBM classification and pathogenesis, as well as the therapeutic approach currently used. Then, we will focus on the modulatory role exerted by pituitary adenylate cyclase-activating peptide, known as PACAP, on GBM malignancy. Specifically, we will describe PACAP ability to interfere with GBM cell proliferation, as well as the tumoral microenvironment. Considering its anti-oncogenic role in GBM, synthesis of PACAP agonist molecules may open new perspectives for combined therapy to existing gold standard treatment.
Insights
Pituitary adenylate cyclase-activating peptide (PACAP) shows anti-oncogenic properties against glioblastoma multiforme (GBM), a deadly brain tumor. PACAP may enhance current GBM treatments by targeting tumor cells and their microenvironment.
Area of Science:
- Neuro-oncology
- Molecular Biology
- Endocrinology
Background:
- Glioblastoma multiforme (GBM) is an aggressive brain tumor with limited treatment options.
- Current GBM therapy involves surgery, radiation, and chemotherapy, often with modest success.
- Understanding novel therapeutic targets is crucial for improving patient outcomes.
Purpose of the Study:
- To review the classification, pathogenesis, and current therapeutic strategies for GBM.
- To elucidate the modulatory role of pituitary adenylate cyclase-activating peptide (PACAP) in GBM.
- To explore the potential of PACAP-based therapies for GBM treatment.
Main Methods:
- Literature review of GBM classification, pathogenesis, and treatment modalities.
- Analysis of studies investigating the role of PACAP in cancer, specifically GBM.
- Examination of PACAP's effects on GBM cell proliferation and the tumor microenvironment.
Main Results:
- PACAP demonstrates an anti-oncogenic role in GBM.
- PACAP interferes with GBM cell proliferation.
- PACAP influences the tumor microenvironment, potentially inhibiting malignancy.
Conclusions:
- PACAP exhibits significant potential as a therapeutic agent against GBM.
- PACAP's anti-oncogenic effects suggest its utility in combination therapies.
- Development of PACAP agonists could offer new treatment avenues for glioblastoma.

01:19Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
