Cancer metastasis: molecular mechanisms and therapeutic interventions

Area of Science:

• Oncology
• Cell Biology
• Biochemistry

Background:

• The metastatic cascade, a hallmark of cancer progression, involves cancer cells spreading to distant organs.
• The 'seed and soil' theory explains metastasis, but the mechanisms of organotropism remain unclear.
• Understanding metastasis organotropism is crucial for developing effective cancer treatments.

Purpose of the Study:

• To elucidate the determinants of cancer metastasis organotropism.
• To explore the link between cancer cell metabolic plasticity, stemness, and oxidative stress.
• To propose pro-oxidative therapeutic strategies for targeting metastatic cancer cells.

Main Methods:

• Characterization of the 'metastatic profile of cancer cells' across different breast cancer subtypes.
• Assessment of the 'redox status of the organ microenvironment'.
• Review and discussion of current and emerging pro-oxidative therapeutic modalities.

Main Results:

• Identified cancer cell metastatic profile and organ microenvironment redox status as key determinants of metastasis organotropism.
• Found a positive correlation between cancer metabolic plasticity and stemness.
• Proposed oxidative stress as a critical factor in cancer cell survival during metastasis.

Conclusions:

• Metastasis organotropism is governed by cancer cell characteristics and the host organ's redox environment.
• Pro-oxidative therapeutics can exploit cancer cell vulnerabilities during metastasis.
• This research offers insights for novel cancer treatment strategies targeting metastasis.
