Article Title: Expression and Regulatory Roles of SKAP2 and Cortactin in Mouse Ovarian Tissue and Oocyte Maturation

doi: 10.1007/s43032-025-01925-4

Figure Lengend Snippet: Immunofluorescence analysis was performed to assess the spatial co-localization of SKAP2 and WAVE2 during oocyte meiotic maturation. As shown in Fig. 8, SKAP2 exhibited predominant localization in the proximal cortical region of oocytes from metaphase I (MI) to metaphase II (MII) stages. Furthermore, SKAP2-WAVE2 co-localization displayed stage-specific patterns: (1) at the MI stage, concentrated asymmetrically at the cell membrane periphery; (2) during anaphase I (AI), distributed along the emergent cell membrane; and (3) at the MII stage, localized specifically at the intercellular junction between daughter cells. All experiments were repeated at least three times

Article Title: Expression and Regulatory Roles of SKAP2 and Cortactin in Mouse Ovarian Tissue and Oocyte Maturation

doi: 10.1007/s43032-025-01925-4

Figure Lengend Snippet: To investigate SKAP2-mediated regulation of WAVE2 membrane dynamics, immunofluorescence analysis was performed in control and SKAP2 knockdown oocytes. As shown in Fig. 10, in control groups, WAVE2 exhibited stable expression and cortical localization throughout meiotic progression, with stage-specific co-localization patterns with F-actin: (1) asymmetric cortical clustering at metaphase I (MI), (2) peripheral membrane distribution during anaphase I (AI), and (3) intercellular junction accumulation at metaphase II (MII). However, SKAP2 depletion significantly reduced WAVE2 expression levels and disrupted its co-localization with F-actin across all meiotic stages. All experiments were repeated at least three times. Data are shown as the mean ± standard deviation. The Student’s t-test was used for data analysis. * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001

Article Title: Dysbindin-1C Is Required for the Survival of Hilar Mossy Cells and the Maturation of Adult Newborn Neurons in Dentate Gyrus

doi: 10.1074/jbc.m114.590927

Figure Lengend Snippet: FIGURE 1. Dysbindin-1A and -1C have distinct spatial and temporal expression patterns and dysbindin-1C is not a subunit of the BLOC-1 complex. Tissue extracts from DBA/2J mice were subjected to SDS-PAGE followed by Western blotting using anti-dysbindin-1 antibody. The brain extract from sdy was used as a negative control, and -actin was used as a loading control. These experiments were repeated three times independently. A, dysbindin-1A is widely expressed in multiple mouse tissues, whereas dysbindin-1C is only expressed in the brain and spinal cord. B, in brain sub-regions, the dysbindin-1A levels are higher than dysbindin-1C in the olfactory bulb, substantia nigra, cerebellar cortex, and brain stem, but dysbindin-1C has higher expression levels than dysbindin-1A in the striatum, cerebral cortex, and hippocampal formation. C, dysbindin-1C is mainly enriched in the synaptic vesicles, whereas dysbindin-1A is mainly localized in the presynaptic membrane. In addition, both dysbindin-1A and -1C are found in the proportion of postsynaptic density. Successful synaptic fractionation is confirmed with VAMP2 as a marker for synaptic vesicles and GluR1 as a marker for the postsynaptic density. D and E, protein levels of dysbindin-1A in the hippocampal formation are gradually decreased. In contrast, the dysbindin-1C expression levels increase at postnatal stages. The chart in E is plotted by the relative intensities (IOD) of the bands in D. F, sedimentation velocity analyses. Mouse brain cytosol was fractioned by ultracentrifugation on a 5–20% (w/v) sucrose gradient and probed with antibodies against dysbindin-1, BLOS1, -dystrobrevin, and WAVE2 by immunoblotting. Fractions 1 and 20 correspond to the top and bottom ends of the gradient, respectively. Dysbindin-1C does not co-sediment with subunits of the BLOC-1 complex, including dysbindin-1A and BLOS1. Moreover, dysbindin-1C does not form a stable DPC complex with -dystrobrevin nor a stable ternary complex with WAVE2 and Abi-1. Arrowheads, nonspecific bands. G, destabilization of the dysbindin-1 in extracts of three BLOC-1 mutants (sdy, pa, and mu). Sdy is the mutant of dysbindin-1; mu is the mutant of muted; and pa is the mutant of pallidin. Inbred strain DBA/2J served as the control for sdy, CHMU/Le for mu, and C57BL/6J for pa.
