HES1 and posterior cortical atrophy: PCa cells have a higher abundance of a number of proteins and PTMs compared with Gr-MDSCs and T cells, such as E-cadherin, Connexin-43, ARID1A, eIF4G, HES1, phospho-Akt (Ser473), phospho-S6 (Ser235/236, Ser240/244), Phospho-NDRG1 (Thr346), phospho-YAP (Ser127), and TAZ (fold change > 5).
