We explored endogenous molecular-cellular network hypothesis for prostate cancer by constructing relevant endogenous interaction network model and analyzing its dynamical properties. Molecular regulations involved in cell proliferation, apoptosis, differentiation and metabolism are included in a hierarchical mathematical modeling scheme. This dynamical network organizes into multiple robust functional states, including physiological and pathological ones. Some states have characteristics of cancer: elevated metabolic and immune activities, high concentration of growth factors and different proliferative, apoptotic and adhesive behaviors. The molecular profile of calculated cancer state agrees with existing experiments. The modeling results have additional predictions which may be validated by further experiment: 1) Prostate supports both stem cell like and liver style proliferation; 2) While prostate supports multiple cell types, including basal, luminal and endocrine cell type differentiated from its stem cell, luminal cell is most likely to be transformed malignantly into androgen independent type cancer; 3) Retinoic acid pathway and C/EBPα are possible therapeutic targets.
