Disorder, Promiscuous Interactions, and Stochasticity Regulate State Switching in the Unstable Prostate

Area of Science:

• Urology
• Cell Biology
• Systems Biology

Background:

• A causal link between benign prostatic hyperplasia (BPH) and prostate cancer is suspected but not widely accepted.
• Prevailing theories do not fully explain the co-occurrence or potential relationship between these two prostate conditions.

Purpose of the Study:

• To propose a novel model for a causal connection between BPH and prostate cancer.
• To elucidate the cellular mechanisms underlying the potential link between these diseases.

Main Methods:

• Application of dynamical systems theory to model cellular behavior.
• Investigation of phenotypic switching in epithelial cells under stress.
• Analysis of the role of intrinsically disordered proteins and 'noise' in cellular plasticity.

Main Results:

• The proposed model suggests that stress can induce phenotypic switching in epithelial cells.
• This switching, driven by protein dynamics and cellular noise, can lead to the development of either BPH or prostate cancer.
• Newly acquired cell phenotypes can cross traditional zonal boundaries, influencing disease manifestation based on the microenvironment.

Conclusions:

• Establishing a causal link between BPH and prostate cancer is feasible through this model.
• Understanding this connection can enhance the comprehension of their etiology.
• This insight may guide improved prevention and treatment strategies for both conditions.
