Neurodegenerative changes in Purkinje cell-specific knockout of Xpa in Ercc6^tm1Gvh/Ercc6^tm1Gvh (Csb^-/-) mice. F-J) Photomicrographs of sagittal cerebellar sections of 25-week old Ercc6^tm1Gvh/Ercc6^tm1Gvh (Csb^-/-) (F1-J1) and Ercc6^tm1Gvh/Ercc6^tm1Gvh Xpa^tm1Gvh/Xpa^tm1Hvs Tg(Pcp2-cre)2Mpin/0 (Csb^-/- Xpa^c/- L7-Cre) mice (F2-J2). F) Silver degeneration staining shows a high level of argyrophilic fibers in the deep cerebellar nuclei (DCN) and the white matter (wm) of Ercc6^tm1Gvh/Ercc6^tm1Gvh Xpa^tm1Gvh/Xpa^tm1Hvs Tg(Pcp2-cre)2Mpin/0 cerebellum (arrow in F2). G) GFAP-immunoperoxidase staining shows increased GFAP staining in the molecular (ml) and Purkinje cell (Pcl) layers of Ercc6^tm1Gvh/Ercc6^tm1Gvh Xpa^tm1Gvh/Xpa^tm1Hvs Tg(Pcp2-cre)2Mpin/0 cerebellar cortex, while no changes occur in the granule cell layer (Gcl). H) Calbindin immunoperoxidase staining reveals calbindin-negative regions in the molecular layer (arrow in H2) of Ercc6^tm1Gvh/Ercc6^tm1Gvh Xpa^tm1Gvh/Xpa^tm1Hvs Tg(Pcp2-cre)2Mpin/0 cerebellar cortex. I) A number of Purkinje cells showed strong nuclear ATF3 staining (arrow in I2). Note that the ATF3 antibody also outlines Purkinje cells because of non-specific cytoplasmatic staining of these cells. J) Active caspase 3 antibody stains sporadic Purkinje cells in Ercc6^tm1Gvh/Ercc6^tm1Gvh Xpa^tm1Gvh/Xpa^tm1Hvs Tg(Pcp2-cre)2Mpin/0 cerebellar cortex (arrow head in J2). Calibration Bars: 500 um (F2); 50 um (H2), 25 um (J2).
