AR and posterior cortical atrophy: For instance, splicing variants of the AR [5], transient receptor potential melastatin 8 (TRPM8) [11], prolactin receptor (PRLR) [12], epidermal growth factor receptor (EGFR) [13], and vascular endothelial growth factor (VEGF) [14] have been found to regulate cell growth, metastasis, and possibly the epithelial-mesenchymal transition (EMT) in PCa.
