Prostate tumor cell plasticity: a consequence of the microenvironment.

Area of Science:

• Oncology
• Cell Biology
• Cancer Research

Background:

• Prostate cancer metastasis is characterized by phenotypic plasticity, enabling cancer cell survival through transitions between epithelial and mesenchymal states.
• This plasticity is crucial for cancer cell survival, influencing motility, invasion, and proliferation in response to microenvironmental cues.
• E-cadherin expression serves as a key marker for tracking tumor plasticity during metastatic progression.

Purpose of the Study:

• To review the role of phenotypic plasticity in prostate cancer metastasis.
• To discuss E-cadherin expression as a marker of tumor plasticity.
• To focus on dynamic tumor-stromal interactions driving mesenchymal-epithelial reversion in bone and liver.

Main Methods:

• Literature review focusing on phenotypic plasticity in cancer metastasis.
• Analysis of E-cadherin expression dynamics during prostate cancer progression.
• Examination of tumor-stromal interactions in specific microenvironments (bone, liver).

Main Results:

• Phenotypic plasticity, involving epithelial-mesenchymal transitions, is integral to prostate cancer metastasis.
• Dynamic changes in E-cadherin expression reflect tumor plasticity throughout metastatic steps.
• Tumor-stromal interactions can induce a mesenchymal-to-epithelial reverting transition in metastatic sites.

Conclusions:

• Phenotypic plasticity and E-cadherin dynamics are critical regulators of prostate cancer metastasis.
• Understanding tumor-stromal interactions is key to deciphering metastatic progression and potential therapeutic targets.
• Mesenchymal-to-epithelial reversion represents a significant adaptive mechanism in bone and liver metastases.
