Figure 1(B) The Western blot analysis of GFP, Spd2 and αTub (loading control) in the brain extracts from wild type (Oregon R, OR), Spd2WT-OE and Spd2DK-OE third instar larva. Representative immune blot images are shown on the left. The signal intensities of Spd2 bands were quantified and normalised against αTub values. The values relative to control of each biological replicate (n = 2) and their means are shown as dots and bars, respectively, in a scatted dot plot on the right. The numbers above the bars indicate means ± Range. GFP-Spd2DK proteins in Spd2DK-OE larval brain extracts showed approximately 2.04-fold higher accumulation than GFP-Spd2WT proteins in Spd2WT-OE brain extracts. (C) The Western blot analysis of Spd2, CycB and αTub in OR, fzrRNAi, Spd2WT-RES and Spd2DK-RES brain extracts. The signal intensities of Spd2 bands were quantified and normalised against αTub values. The values relative to control and their means are presented in a scatted dot plot on the right (biological replicate n = 2). Means ± Range are shown above the bars. RFP-Spd2DK proteins in Spd2DK-RES larval brain extracts showed approximately 2.08-fold higher accumulation than RFP-Spd2WT proteins in Spd2WT-RES brain extracts.(D) Larval brains of OR, Spd2WT-RES, fzrRNAi and Spd2WT-OE flies were stained by an anti-Spd2 antibody. Representative images of NBs are shown on the top. Scale bar: 10 µm. The local signal intensities of Spd2 immunofluorescence at the centrosomes and in the cytoplasm of individual NBs in each brain were measured, and the normalised Spd2 signal intensities in individual NBs were presented as scattered dot plots (see Materials and Methods for detail). The lines indicate means ± SD. The numbers of NBs (n) and the numbers of brains analysed (N) are control: n= 29 (N = 6), Spd2WT-RES: n = 30 (N = 4), fzrRNA: n = 30 (N = 6), and Spd2WT-OE: n = 27 (N = 10). P values were calculated using non-parametric two-tailed Mann-Whitney tests. Based on these results, the relative centrosomal Spd2 protein levels in NBs can be estimated as wildtype (or control) : Spd2WT-RES: fzrRNAi: Spd2DK-RES: Spd2WT-OE: Spd2DK-OE ­= 1: 1.00~1.18: 1.06~1.29: 2.08~2.45 (= 1.00~1.18 x 2.08): 1.93~3.62: 3.94 ~ 7.38 (= 1.93~3.62 x 2.04
Figure 2(C) In time lapse movies, NBs that showed an active centrosome that was attached to the cortex ("Attached") and NBs with both two centrosomes being inactivated and detached from the cortex ("Detached") in interphase were counted in third instar larval brains of the indicated fly lines and their proportions are presented in bar graphs. The numbers of NBs analysed from at least four brains (n) are Control: 29, fzrRNAi: 80, Spd2WT-RES: 45, Spd2DK-RES: 52, Spd2WT-OE: 43, Spd2DK-OE: 40, Spd2WT-OE + fzrRNAi: 72. p-values are fzrRNAi: 0.0069, Spd2WT-RES: 0.2479, Spd2DK-RES: 0.0116, Spd2WT-OE: <0.0001, Spd2DK-OE: <0.0001, Spd2WT-OE + fzrRNAi: 0.0008 (Pearson's chi-squared tests were performed between control and each condition).(E) The signal intensities of the indicated centriolar and PCM proteins at two centrosomes were quantified in individual interphase NBs in Spd2WT-RES and Spd2DK-RES larval brains, and their asymmetric distributions of their centrosomal signals between the two centrosomes are presented as Asymmetric Indexes (see Materials and Method) in a scatted dot plot. Red bars represent means ± SD. The numbers of NBs analysed from at least 3 different brains of Spd2WT-RES and Spd2DK-RES (n) were 40 and 40 for Asl, 40 and 41 for RFP-Spd2, 42 and 37 for Cnn, 40 and 41 for γTub, and 40 and 40 for AurA.
Figure 3(D) Division axis deviations were separately analysed in NBs with apically attached interphase centrosomes ("attached") and those with centrosomes being detached from the cortex ("detached") for each line, using the same dataset as in Fig. 3C. The same control data as in Fig. 3C is shown for reference. fzrRNA detached (mean ± SD: 34.62° ± 23.39), Spd2DK-OE detached (64.01° ± 33.93), and Spd2WT-OE+fzrRNAi attached (39.55° ± 27.08) and detached (59.08° ± 34.88) brains showed statistically significant differences from control, while NBs with cortically attached centrosomes in any of the lines did not show significant differences. n: the number of NB divisions analysed from at least four brains for each line. p-values were calculated using Mann-Whitney U tests comparing with control and are shown above the dots.
Figure 4(B) Selected images from time-lapse microscopy of NBs in control (wor>mCh-Tub, pUbq-GFP-Fzr, top panels) and Spd2DK-OE (lower panels) larval brains (Movies EV1, EV10). In the control NB, the daughter centrosomes (blue arrowheads) first matured (-5.0 min) and was segregated into the daughter NB (12.0 min), while the mother centrosome (yellow arrowheads) matured a little later (0.0 min) and segregated into the GMC. In contrast, in the Spd2DK-OE NB, both centrosomes lost microtubule nucleation activity in interphase (red arrowheads). The centrosome that matured earlier (blue arrowheads, -6.0 min) was incorrectly segregated into the GMC (12.0 min) while the centrosome that matured later (yellow arrowheads, 0.0 min) was segregated into the NB (12.0 min). Dotted white lines outline the dividing NBs and the newly formed GMC, which are also marked by asterisks.
Figure 5(C, D) Representative images of interphase NBs in fixed wor>lacZ (control, top panels) and HA-Spd2WT-OE larval brains expressing Polo-GFP from the native promoter and stained for DAPI and Spd2 (C). Asymmetric indexes of Polo-GFP in interphase NBs wor>lacZ (control, top panels) and HA-Spd2WT-OE larval brains (D). 38 and 39 NBs (n) from at least three brains were analysed in each line. The asymmetric distribution of Polo-GFP at interphase centrosomes was unaffected by HA-Spd2WT overexpression.(E) Representative images of interphase NBs in fixed mCh-Spd2WT-RES (top panels) and mCH-Spd2DK-RES larval brains and stained for DAPI, γTub and Cnn. Both multichannel and single-channel images of mCh-Spd2, γTub and Cnn are shown. Dotted yellow squares highlight centrosomes and their magnified images are shown in insets. Similar to Spd2DK-RES NBs, in mCh-Spd2CONS-RES NBs, Spd2 and γTub were more symmetrically accumulated at the two centrosomes than in mCh-Spd2WT-RES NBs, but Cnn was still asymmetrically distributed.(G, H) FRAP analyses of the centrosomal Spd2 fluorescent signals in Spd2WT-RES and Spd2DK-OE NBs. (G) Representative images from time-lapse movies (Movies EV13, EV14) of Spd2 fluorescent signals in Spd2WT-RES NBs (top panels) and Spd2DK-OE NBs (lower panels) upon photobleaching. (H) The recoveries of the fluorescent intensities of centrosomal Spd2 signals after photobleaching were measured in Spd2WT-RES (n = 7) and Spd2DK-OE NBs (n = 5). Means ± SEM of the normalised fluorescent intensities are shown in a line graph. Centrosomal Spd2 signals recovered more fully after photobleaching in Spd2DK-OE NBs than in Spd2WT-RES NBs.
