Abstract: Currently, the biggest challenge for prostate cancer (PCa) is to understand the mechanism by which the disease acquires the castration-resistant phenotype and progresses to a fatal disease. PCa has a high genetic heterogeneity, and cannot be separated into well-defined molecular subtypes. Despite this, there is consensus about the role of the androgen receptor (AR) in all stages of the disease, including the transition to the castration-resistant phenotype. Since AR is a transcription factor, we investigated the possibility of PCa presenting a pattern of global gene expression during disease progression. By analyzing the TCGA and CCLE datasets, we were able to find a pattern of waves of genes being expressed during each stage of disease progression. This phenomenon suggests the existence of a mechanism that globally regulates gene expression, being AR, telomeres, and zinc finger proteins (ZNF), three important players. The AR modulates the telomere biology, and its transcription is regulated by ZNF. Recently, a study suggested that the telomere length might influence the expression of ZNF. Thus, we hypothesized that changes in the triad AR, telomeres, and ZNF control gene expression during the progression of PCa.
