Targeting bone metastases starting from the preneoplastic niche: home sweet home
Abstract:
The metastatic process is a multistep coordinated event with a high degree of efficiency. Specific subpopulations of cancer stem cells, with tumor-initiating and migratory capacity, can selectively migrate towards sites that are able to promote survival and/or proliferation of metastatic tumor cells through a microenvironment modification. Cross-talk between the bone microenvironment and cancer cells can facilitate bone tropism of cancer cells. Fully understanding this complexity represents a major challenge in anti-cancer research and a mandatory step towards the development of new drugs potentially able not only to reduce the consequences of bone lesions but also to target the metastatic process in visceral sites.
Insights
Cancer stem cells migrate efficiently to specific sites, modifying the microenvironment for survival and proliferation. Understanding this process is key to developing new anti-cancer drugs targeting metastasis.
Area of Science:
- Oncology
- Cancer Biology
- Cellular Biology
Background:
- Metastasis is an efficient, multistep process driven by cancer stem cells.
- Cancer stem cells possess tumor-initiating and migratory capabilities.
- These cells selectively migrate to supportive microenvironments.
Discussion:
- The bone microenvironment and cancer cells engage in cross-talk, promoting bone tropism.
- Microenvironment modification is crucial for metastatic tumor cell survival and proliferation.
- Understanding cancer cell-microenvironment interactions is vital for effective anti-cancer therapies.
Key Insights:
- Cancer stem cells actively shape their metastatic niche.
- Interactions between cancer cells and the bone microenvironment facilitate metastasis.
- Targeting these interactions could inhibit cancer spread.
Outlook:
- Further research into the metastatic cascade is essential.
- Developing drugs to mitigate bone lesion consequences is a priority.
- New therapies should aim to target the broader metastatic process in visceral sites.

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...
