Figure 6. Histone H2A ubiquitination accompanied by <t>BRCA1</t> activation is the hallmark phenotype of BRAP LOF (A) Immunoblotting of histone extracts from NPCs as well as from embryonic, neonatal, adult cerebral cortical tissues, and quantification (Mean G SD) of increases in histone H2Aub (total H2Aub and H2AubK119, respectively) resulted from Brap LOF. n = 3–6 biological replicates. p-values calculated by Student’s t test are indicated. (B) Immunoblotting of Brca1 in various cells and tissues, showing that Brap LOF results in increased Brca1 abundance. (C) Immunoblotting of nuclear vs cytoplasmic fractions of MEFs at P1, showing increased nuclear localization of Brca1 in Brap/ cells. (D) Brca1 (red) and NeuN (green) double immunohistology images of cerebral cortical sections of BrapcKONPC and control mice at four months of age. Representative images are shown. Note the increased intensity and density of Brca1 puncta in the nuclei of BrapcKONPC cortical neurons (NeuN+). (E and F) Immunoblotting analyses of histone extracts from cerebral cortical tissues of three-month-old mice, showing increased ubiquitination of H2A variants targeted by Brca1 (E) along with total histone H2A ubiquitination (F). (G) Double immunohistology staining of cortical sections of 4-month old WT or BrapcKONPC mice with antibodies against Gfap (green) and histone H3 (red), showing reduced nuclear histones in cells surrounded by reactive astrocytes (circles) in BrapcKONPC cortical tissues. Representative images are shown. Nuclear DNA was stained with Hoechst 33342. Bars: 50 um or as indicated. See also Figure S3.
