Figure 4Chromosome parameters obtained for a representative oocyte with normal segregation pattern are shown in A-D on the vertical axis, and time in min on the horizontal axis relative to the anaphase II onset. Thin grey lines in A-D represent individual chromosomes; thick black line in C-D shows the mean value for each timepoint. On the schemes near the charts chromosomes are red with green centromeres; spindle equator in A and spindle axis in B-C are indicated by dashed lines. Changes in distance to the equator plane for all chromosomes in the representative oocyte with normal segregation pattern, shown in Fig 3. The analysed distance is indicated by a black arrowed line on the scheme above the chart. Changes in distance to the spindle axis (shown on the scheme by a black arrowed line) for all chromosomes in oocyte from Fig 3. Changes in chromosome orientation for all chromosomes in oocyte from Fig 3. The orientation is characterized by the angle (highlighted black) between the spindle axis and the line connecting the sister centromeres (black solid line on the scheme). Chromosome parameters obtained for a representative oocyte with normal segregation pattern are shown in A-D on the vertical axis, and time in min on the horizontal axis relative to the anaphase II onset. Thin grey lines in A-D represent individual chromosomes; thick black line in C-D shows the mean value for each timepoint. (D) Changes in inter-centromere distance, shown on the scheme by black arrowed line, for all chromosomes in oocyte from Fig 3. Kinetochore-MT attachments in oocytes released from the CSF-dependent metaphase arrest were visualized using an anti-tubulin antibody (white), an anti-centromeric ACA antibody (green) and DAPI to label chromatin (red). The image represents maxiumum intensity projection through all z-planes containing MTs. Single z-planes of representative chromosomes displaying amphitelic or merotelic/lateral attachments are shown to the right. Scale bar, 10μm. Chromosomes with amphitelic (green) and merotelic/lateral (grey) attachments were plotted according to their inter-centromere distance (on the horizontal axis) and distance to spindle equator (vertical axis). The inter-centromere distance in fixed oocytes is 1.2±0.2 μm for amphitelic and 1.0±0.2 μm for merotelic attachments (Mean±SD). Data shown for 95 chromosomes taken from 5 oocytes released from the CSF-dependent metaphase II arrest.
WNK4 and SPAK specifically accumulate and form puncta in the distal convoluted tubule of CUL3WT/Δ403–459 mice.Figure 5Representative pseudocoloured maximum-intensity z projections of immunofluorescence stained kidney sections showing the distribution of the WNK/SPAK pathway components between CUL3WT/Δ403-459 and CUL3WTmice at a minimum 4-h fasting baseline (n = 4 per genotype). CUL3 and KLHL3 are comparable between genotypes, with significantly higher levels of CUL3 in the proximal convoluted tubule (PCT) compared to the weak staining in distal convoluted tubule (DCT) and thick ascending limb of the loop of Henle (TAL), while KLHL3 shows higher expression in the DCT/TAL cytosol with staining of the PCT confined to the apical membrane. Total (t) and phospho (p) NCC Thr44 and SPAK Thr243 show increased apical membrane expression in the parvalbumin (PVALB)-positive early and late (PVALB-negative) DCT of CUL3WT/Δ403-459mice. Unexpectedly, the increased levels of WNK4 and SPAK resulted in the formation of discrete puncta specifically in the DCT of CUL3WT/Δ403-459mice. It is possible that the autophagy-lysosomal system may attempt to compensate and degrade these excess proteins although the WNK4 puncta do not colocalise with the lysosomal marker LAMP1. Scale bar, 20 μm. Representative immunohistochemistry staining of KLHL3 and CUL3 in humankidney sections (n = 6). KLHL3 shows preferential DCT/TAL cytosolic staining similar to the mouse despite no evidence of PCT apical staining as seen in (A). CUL3 exhibits preferential basolateral cytosolic staining of the PCT with similarly low levels of diffuse staining in the DCT/TAL to that of the mouse. Scale bar, 100 μm.
