Based on these results, we speculated that proper nuclear positioning is controlled by a MyoII-dependent mechanical force applied to the nuclear envelope via physical links between F-actin and the LINC complex. The stained glass window below shows bilateral symmetry of 5. Drosophila is an excellent model system for studying these mechanisms (Inaki et al., 2016, 2018b; Uechi and Kuranaga, 2018). Thus, MyoII and the LINC complex play important roles in the LR-symmetric rearrangement of the nuclei, which is required for or coupled with the subsequent LR-asymmetric morphogenesis (Fig. To determine how nuclear positioning affects left-right (LR) development in the Drosophila anterior midgut (AMG), we developed a surface-modeling method to measure and describe nuclear behavior at stages 13-14, captured in three-dimensional time-lapse movies.
Wnt4 signaling controlled the collectivity of nuclear arrangement. Thus, accelerated migration may be responsible for the dispersion of nuclei in dlp mutants. In such cases, complex LR-asymmetric structures can be built with a limited number of machineries. I created this design and learnt about Riso Printing from Carl at Monoprint through a workshop. The stained glass window below shows bilateral symmetry definition. The shy bairns get nowt print was quite popular lately so I've used the saying again, this time adding a LIT match and of course the Geordie icon – the magpie sitting right next to it. Competing interests. Here, we have demonstrated that the bilaterally symmetric arrangement of the nuclei in the visceral muscles of the AMG is required for the LR-asymmetric development of this organ (Fig. Therefore, we hypothesized that dlp contributes to Wnt4 signaling in the visceral muscles, and thus contributes to LR-asymmetric AMG morphogenesis. Understanding Warp tool.
Craig played an important role in anti-racism campaigns and recent community projects and events, including Curious Arts and the NewBridge Project. We then averaged the mean values from 10 embryos (the average number of nuclei in each embryo was 20. The curved roof of Newcastle Central Station. 2E) (Morel and Arias, 2004; Wehrli et al., 2000). Visceral muscle-cell nuclei are collectively aligned in distinct regions in the wild-type embryonic midgut. Before these tests, we confirmed that all data had normal distributions. Using Quick Shape function to make easy shapes and lines. We speculated that this might be due to potential LR defects associated with dlp misexpression in some tissues. I ran a series of workshops with the Laing Art Gallery exploring the beautiful artwork of the Lindisfarne Gospels. In our previous studies relying on fixed embryos, the first indication of LR-asymmetric changes was found in nuclei in the posterior part of the AMG (Kuroda et al., 2012; Okumura et al., 2010; Taniguchi et al., 2007). Support team who will be happy to help. I then digitally drew these ( and refined them a lot) in Procreate on my iPad, I sized them all and added backgrounds. The time-lapse images were saved as LSM files in ZEN software (2012 SP1 black edition, Release Version 8.
We have previously demonstrated that the angle of the long axes of the nuclei relative to the midline changed in the right side of wild-type embryos but not in various mutants in which AMG LR asymmetry is disrupted, including Wnt4 and MyoII mutants (Kuroda et al., 2012; Okumura et al., 2010). The surface models of the visceral muscles were transparently colored and then added to the layers (Fig. Although 65E04-driven UAS-Red S tinger expression is highly specific to the visceral muscles, some nuclei outside the visceral muscles were also labeled. I wanted to show the vital hidden history of the North East and to show some landmarks that are sometimes overlooked. The calculated values were copied to Excel, and the average of the mean values and their standard deviations were calculated using the AVERAGE and STDEV. MyoII contributes to LINC complex-dependent nuclear migration in various systems by physically linking F-actin (Gundersen and Worman, 2013). Please note, these features may not be available on all Internet browsers. We obtained 3D time-lapse movies using z stacks (13-15 images at 5 µm intervals). Given that the nucleus can provide this type of dynamic force, the positioning of the nuclei may help to create mechanical forces that promote LR-asymmetric morphogenesis. Mutations of genes that encode key molecules for nuclear positioning, such as the LINC complex, are associated with Emery-Dreifuss muscular dystrophy and cerebellar ataxia (Gundersen and Worman, 2013), and genetic analysis in model animals has revealed that the LINC complex plays key roles in the development of these diseases (Azevedo and Baylies, 2020). The densely crowded nuclei in these regions actively rearranged their positions relative to neighboring nuclei; hereafter, we refer to this as collective nuclear behavior. Although arm-GAL4 is used to drive ubiquitous expression, including in visceral muscles, dlp expression driven by arm-GAL4 in dlp3 homozygotes did not suppress LR defects (Fig. Collectively, the proper nuclear positioning, referring to the overall positioning of the nuclei with respect to the midline, was maintained from T1 to T4; however, the positions of the individual nuclei changed relative to one another (Fig. The LINC complex, which consists of KASH- and SUN-domain proteins, physically links the nuclear envelope and the cytoskeleton and plays crucial roles in nuclear migration in several species, including Drosophila (Calero-Cuenca et al., 2018).
At this point, it is not clear whether there is some functional interplay between Wnt4 signaling and MyoII/LINC complex. So, the area of the four triangles is; total area of triangles = 4 × ½ × (2. I'm really looking forwards to the final design and have been researching key figures of the North East's rich history to document on the illustration. A video showing how a matchbox book was created. High-rise apartment blocks from Elswick in Newcastle. For example, cell chirality in snail and nematode blastomeres determines their subsequent LR-asymmetric organ and body development (Davison, 2020; Kuroda, 2015; Pohl and Bao, 2010). He died in 2009 aged 95. 1C, D, Movie 1), we speculated that the reduced collectivity of nuclei in dlp mutants could be due to augmented movement.
Recent studies show that the mechanisms determining LR asymmetry are evolutionarily divergent (Davison, 2020; Hobert et al., 2002; Inaki et al., 2018a, b; Kuroda, 2015). These results suggest that collective nuclear behavior depends on Wnt4 signaling. Adele Emily Sandé MBE, known professionally as Emeli Sandé, is a singer and songwriter born in Sunderland to an English mother and Zambian father. I recently did a talk for Durham University's Summer in the City Festival Art Prize Art School event talking about the minority suffragettes in British History who helped pave the way to women being able to vote. Each of the triangles is an isosceles right triangle with leg lengths of 2. The Riso Printing workshop was so easy once you understand layering, and can be done in Procreate and Photoshop. Copy and paste layer. How to save the image. How to use the Colour Drop tool to fill shapes. We used Python Script and NumPy library in Maya version 2018 (Autodesk) to automatically connect each nucleus in the lower region of the surface model (40-80 µm below the anterior tip) to its nearest most-posterior neighbor and to calculate the length of the connecting line (Fig. To easily obtain measurements in 3D space, Maya version 2018 (Autodesk, San Rafael, CA), a computer animation and modeling software, was used to animate the 3D-surface model (Park et al., 2019). In the absence of MyoII or a LINC-complex component, the nuclei align LR asymmetrically but the AMG develops LR symmetrically (Fig. Thus, in this study, the nuclei were divided by whether they were in the anterior or posterior region of the AMG, corresponding to 0-40 µm and 40-80 µm from the anterior tip of the midgut, respectively (Fig.
Flickr Creative Commons Images. We then measured the distance from the center of each nucleus to the midline (Fig. Select the three dots, or menu, icon on the right side of the player to download an audio file or adjust the playback speed. Then of course the art reveal at NCA Gallery. Thus, nuclear positioning was LR-asymmetric in Msp300ΔKASH and zip2 mutants, although it was LR symmetric in wild-type embryos (Fig. Mean values calculated for migration distance (μm) and averaged for three embryos demonstrated that nuclei migrated farther in both left and right sides of dlp3 mutants than in wild-type embryos; the difference in the right side was statistically significant (Fig. Stained glass inspired by St Paul's Church in Jarrow. Author contributions. We plotted the position of individual nuclei every 2. Importing a photo of previous sketch. Now, the area of the 10-inch square is given by; Area of square = 10 × 10 = 100 in².
I've loved going to visit the archive, uncovering a new snippet of information or photo that connects to what's being created. MyoII provides contractile force to F-actin, which is involved in LINC complex-dependent nuclear movement in other systems (Gundersen and Worman, 2013). Using text in Procreate. This process helped me develop the pattern, colours and textures on a larger scale. Therefore, proper nuclear positioning in the visceral muscles may be a prerequisite for establishing normal LR asymmetry, but it may also be integral to the mechanism of LR-asymmetrical development.
