Abstract:
The transforming growth factor beta (TGF-β) signaling is fundamental for correct embryonic development. However, alterations of this pathway have been correlated with oncogenesis, tumor progression and sustaining of cancer stem cells (CSCs). Cripto-1 (CR-1) and Nodal are two embryonic proteins involved in TGF-β signaling. Their expression is almost undetectable in terminally differentiated cells, but they are often re-expressed in tumor cells, especially in CSCs. Moreover, cancer cells that show high levels of CR-1 and/or Nodal display more aggressive phenotypes in vitro, while in vivo their expression correlates with a worse prognosis in several human cancers. The ability to target CSCs still represents an unmet medical need for the complete eradication of certain types of tumors. Given the prognostic role and the selective expression of CR-1 and Nodal on cancer cells, they represent archetypes for targeted therapy. The aim of this review is to clarify the role of CR-1 and Nodal in cancer stem populations and to summarize the current therapeutic strategy to target CSCs using monoclonal antibodies (mAbs) or other molecular tools to interfere with these two proteins.
Insights
Cripto-1 (CR-1) and Nodal, embryonic proteins re-expressed in cancer stem cells (CSCs), drive tumor progression. Targeting CR-1 and Nodal offers a promising therapeutic strategy for eradicating tumors by eliminating CSCs.
Area of Science:
- Oncology
- Developmental Biology
- Molecular Signaling
Background:
- Transforming growth factor beta (TGF-β) signaling is crucial for embryonic development but implicated in cancer progression and cancer stem cell (CSC) maintenance.
- Cripto-1 (CR-1) and Nodal, embryonic proteins within the TGF-β pathway, are re-expressed in tumor cells, particularly CSCs, and associated with aggressive phenotypes and poor prognosis.
Purpose of the Study:
- To elucidate the role of CR-1 and Nodal in cancer stem cell populations.
- To review current therapeutic strategies targeting CR-1 and Nodal for cancer stem cell eradication.
Main Methods:
- Literature review focusing on the expression and function of CR-1 and Nodal in cancer stem cells.
- Analysis of therapeutic approaches utilizing monoclonal antibodies (mAbs) and other molecular tools against CR-1 and Nodal.
Main Results:
- CR-1 and Nodal expression is elevated in CSCs and correlates with increased tumor aggressiveness and poorer patient outcomes.
- These proteins represent viable targets for novel cancer therapies due to their selective expression on cancer cells.
Conclusions:
- CR-1 and Nodal play significant roles in sustaining cancer stem cell populations and tumor progression.
- Targeting CR-1 and Nodal, particularly through antibody-based therapies, holds potential for effective cancer treatment by eliminating CSCs.
