GPM6B and posterior cortical atrophy: Therefore, we decided to conduct further research on GPM6B.To determine the expression pattern of GPM6B in PCa, we further analyzed GSE46602 (t = 5.072, p < 0.0001), GSE69223 (t = 7.522, p < 0.0001), GSE27616 (t = 3.174, p = 0.0088), and a TCGA cohort (t = 11.52, p < 0.0001).
