PTEN and Seizure: Second, as other seizure models result in abnormal migration of adult-born dentate gyrus neurons (Dashtipour et al., 2003; Shapiro et al., 2008, 2011; Murphy et al., 2012) and PTEN has been shown to be essential for cell migration and lamination of the cerebellum (Marino et al., 2002; Yue et al., 2005), future work could assess whether the greater number of Ki67+ and CC3+ cells in hilus and oGCL indicates abnormal migration.
