Abstract:
Osteosarcoma and Ewing sarcoma are the most prevalent bone pediatric tumors. Despite intensive basic and medical research studies to discover new therapeutics and to improve current treatments, almost 40% of osteosarcoma and Ewing sarcoma patients succumb to the disease. Patients with poor prognosis are related to either the presence of metastases at diagnosis or resistance to chemotherapy. Over the past ten years, considerable interest for the Hippo/YAP signaling pathway has taken place within the cancer research community. This signaling pathway operates at different steps of tumor progression: Primary tumor growth, angiogenesis, epithelial to mesenchymal transition, and metastatic dissemination. This review discusses the current knowledge about the involvement of the Hippo signaling pathway in cancer and specifically in paediatric bone sarcoma progression.
Insights
Pediatric bone sarcomas like osteosarcoma and Ewing sarcoma remain deadly, with nearly 40% of patients succumbing to the disease. Emerging research highlights the Hippo/YAP signaling pathway
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Osteosarcoma and Ewing sarcoma are the most common pediatric bone cancers.
- Despite advances, nearly 40% of patients with these sarcomas do not survive due to metastasis or chemotherapy resistance.
- The Hippo/YAP signaling pathway has gained attention for its role in cancer progression.
Purpose of the Study:
- To review the current understanding of the Hippo signaling pathway's involvement in cancer.
- To specifically examine the role of the Hippo signaling pathway in the progression of pediatric bone sarcomas.
Main Methods:
- Literature review of studies on the Hippo signaling pathway and pediatric bone sarcomas.
- Analysis of the pathway's functions in tumor growth, angiogenesis, epithelial to mesenchymal transition, and metastasis.
Main Results:
- The Hippo signaling pathway influences multiple stages of tumor progression.
- This pathway is implicated in primary tumor growth, the formation of new blood vessels (angiogenesis), and the spread of cancer cells (metastatic dissemination).
Conclusions:
- The Hippo signaling pathway is a critical player in the progression of pediatric bone sarcomas.
- Understanding this pathway may reveal new therapeutic targets for osteosarcoma and Ewing sarcoma.
