MYH9 and posterior cortical atrophy: Unexpectedly, although the total MYH9 protein without DHT treatment was slightly increased in LNCaP-AI-I and LNCaP-AI+F cells, it was not significantly different among the four PCa cell lines (Figures 7C, E), which was similar to the total AR in LNCaP, LNCaP-AI cells (Figures 1C, D).
