Abstract:
Paracrine Hedgehog (Hh) signaling, in which tumor-derived Hh ligands activate stromal cells, has been implicated in the development and progression of many cancers. Recent data suggest that Hh-targeted therapeutics exert direct effects on host cells, thus interrupting a "vicious cycle" to bone metastasis that involves osteoblasts, osteoclasts, and tumor cells.
Insights
Paracrine Hedgehog (Hh) signaling drives cancer progression by activating stromal cells. Hh-targeted therapies may disrupt bone metastasis by affecting host cells like osteoblasts and osteoclasts.
Area of Science:
- Oncology
- Cell Biology
- Cancer Metastasis
Background:
- Paracrine Hedgehog (Hh) signaling, where tumor-derived Hh ligands activate stromal cells, is crucial in cancer development and progression.
- This signaling pathway plays a role in the complex interactions driving bone metastasis.
Purpose of the Study:
- To investigate the role of paracrine Hedgehog signaling in cancer.
- To explore the potential of Hh-targeted therapeutics in disrupting cancer progression, particularly bone metastasis.
Main Methods:
- Analysis of Hh signaling pathways in cancer models.
- Evaluation of Hh-targeted therapeutics' effects on tumor cells and host cells involved in bone metastasis.
Main Results:
- Tumor-derived Hh ligands activate stromal cells, promoting cancer progression.
- Hh-targeted therapeutics demonstrate direct effects on host cells, including osteoblasts and osteoclasts.
Conclusions:
- Paracrine Hh signaling is a key driver in multiple cancers.
- Hh-targeted therapies offer a potential strategy to interrupt the cycle of bone metastasis by targeting both tumor and host cells.

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...
