Figure Lengend Snippet: Figure 3. Analysis of WAVE1, WAVE2, and WAVE3 protein levels. Western analysis was performed on 50 g of protein extracted from the cerebral cortex and hippocampus of wild- type(Wt)miceaswellasfrommiceheterozygous(Het)andhomozygous(KO)forthegene-trap insertion (n 3). The analysis was performed using an anti-WAVE1 polyclonal primary anti- body (A), an anti-WAVE2 polyclonal primary antibody (B), and an anti-WAVE3 polyclonal pri- maryantibody(C).Allblotswerenormalizedbyreprobingwithananti-actinprimaryantibody.

Article Title: SKAP2 regulates Arp2/3 complex for actin-mediated asymmetric cytokinesis by interacting with WAVE2 in mouse oocytes

doi: 10.1080/15384101.2017.1380126

Figure Lengend Snippet: Effects of SKAP2 RNAi on ARP2 and WAVE2 expression. (A) Subcellular localization of ARP2 after SKAP2 siRNA injection. ARP2 was mainly distributed at the membrane in the control oocytes, whereas ARP2 expression was barely detectable in the siRNA-injected group. Green: ARP2; blue: chromatin. Bar = 20 μm. (B) Localization of WAVE2 after SKAP2 siRNA injection. WAVE2 was expressed around the spindle, whereas no specific localization of WAVE2 was observed around spindle in the siRNA-injected group. Red: WAVE2; blue: chromatin. Bar = 20 μm. (C) The fluorescence intensity of ARP2 in the SKAP2 siRNA-injected oocytes was decreased. (D) The fluorescence intensity of WAVE2 in SKAP2 siRNA-injected oocytes was significantly reduced. (E) ARP2 expression was reduced after SKAP2 siRNA injection by western blotting examination, as the relative intensity of ARP2 protein was significantly decreased. (F) WAVE2 expression was decreased after SKAP2 siRNA injection by western blotting analysis, as the relative intensity of WAVE2 protein was significantly reduced. *: significant difference (P < 0.05).

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.
