Jabre, Saline. "Impact of mechanical stress on nucleus morphology and transcription on skeletal muscle". Electronic Thesis or Diss., Sorbonne université, 2022. http://www.theses.fr/2022SORUS561.
Texto completo da fonteThe lamina, and specifically A-type lamins, are major contributors to nuclear stiffness and deformations. However, chromatin and its histone modification states also contribute to nuclear mechanics independently of A-type lamins. How A-type lamins and chromatin-mediated mechanoresponse contribute to mechanical load-mediated adaptation in normal and pathological skeletal muscle remains unknown. We sought to determine how muscle differentiation impacts nuclear characteristics in muscle cell precursors (MuSCs) and myotubes. Then, we investigated the respective roles of nuclear envelope proteins (lamin A/C, SUN1 and SUN2) and drug-modulated chromatin compaction on the mechanical load-mediated nuclear response in myonuclei. We used immortalized MuSCs obtained from healthy patients and analyzed nuclear shape and chromatin characteristics in MuSCs and myotubes obtained after 72h of differentiation. Histone modifications were analyzed: a) histone H3 lysine4 tri-methylation (H3K4me3) and H3K4 acetylation (H3K4ac), associated with transcriptionally active genes, b) H3K27 tri-methylation (H3K27me3), a chromatin repression marker, associated with facultative heterochromatin and c) H3K9 tri-methylation (H3K9me3), a chromatin repression marker associated with constitutive heterochromatin and mainly located at the nuclear periphery. Myotube differentiation was associated with nuclear elongation and significant reduction in nuclear volume. In addition, the relative intensity of nuclear H3K27me3 (chromatin repression marker) labelling was significantly lower in myotubes compared to MuSCs, whereas nuclear H3K9me3 and H3K4me3 (chromatin active marker) intensities were higher in myotubes compared to MuSCs, thereby showing that myogenic differentiation is modulating the accessibility of the transcriptional machinery. Myotubes were silenced for LMNA expression with silencing mRNA strategies and submitted to a cyclic stretch (10%,4hours) to investigate A-type lamin’ roles in nuclear shape and chromatin organization during mechanical stress. A-type lamin deficient myotubes had abnormal nuclear shape in static conditions and nuclear deformations further increased after cyclic stretch. Cyclic stretch was associated with a significant increase in nuclear volume in control myotubes that was abolished in A-type lamin deficient myotubes. In addition, stretching increased the intensity of the H3K27me3 and reduced H3K4me3 and H3K4ac intensities of labelling in nuclei from control myotubes. Importantly, A-type lamin deficiency was associated with higher intensity in chromatin active markers at baseline and a paradoxical increased in H3K4me3 after stretch. Consistent modifications in histone modifications were obtained by western-blots in control and A-type deficient myotubes. Interesting, stretch reduced H3K4me3 intensity both in SUN2 or SUN1-deficient myotubes while the increase in the nuclear intensity of the H3K27me3 was abolished in stretched SUN2-deficient myotubes. Transcriptomic changes associated with A-type lamin deficiency support these results. Trichostatin A (TSA) is a powerful and specific Class I and II histone deacetylase inhibitor (HDACi), widely used to increase the expression of genes silenced by chromatin condensation, thereby favoring chromatin decompaction. TSA increased nuclear volume without affecting nuclear shape both in static and stretched conditions. In addition, TSA decreased H3K27me3 and H3K9me3 intensities in static myotubes but did not prevent the stretch-induced increase in H3K27me3 intensity. Overall, our study highlights crucial changes of histone post-translational markers during muscle differentiation and upon mechanical challenge. A-type lamins appear crucial to prevent abnormal activation of chromatin active markers in mechanically challenged myotubes. Moreover, our results suggest that the nuclear mechano-response is tightly regulated by nuclear envelope proteins in skeletal muscle
Meaders, Johnathan Lee. "Growth, Morphology, and Positioning of Microtubule Asters in Large Zygotes:". Thesis, Boston College, 2020. http://hdl.handle.net/2345/bc-ir:109018.
Texto completo da fonteMicrotubule (MT) asters are radial arrays of MTs nucleated from a microtubule organizingcenter (MTOC) such as the centrosome. Within many cell types, which display highly diverse size and shape, MT asters orchestrate spatial positioning of organelles to ensure proper cellular function throughout the cell cycle and development. Therefore, asters have adopted a wide variety of sizes and morphologies, which are directly affects how they migrate and position within the cell. In large cells, for example during embryonic development, asters growth to sizes on the scales of hundreds of microns to millimeters. Due to this relatively enormous size scale, it is widely accepted that MT asters migrate primarily through pulling mechanisms driven by dynein located in the cytoplasm and/or the cell cortex. Moreover, prior to this dissertation, significant contributions from pushing forces as a result of aster growth and expansion against the cell cortex have not been detected in large cells. Here we have reinvestigated sperm aster growth, morphology, and positioning of MT asters using the large interphase sperm aster of the sea urchin zygote, which is historically a powerful system due to long range migration of the sperm aster to the geometric cell center following fertilization. First, through live-cell quantification of sperm aster growth and geometry, chemical manipulation of aster geometry, inhibition of dynein, and targeted chemical ablation, we show that the sperm aster migrates to the zygote center predominantly through a pushing-based mechanism that appears to largely independent of proposed pulling models. Second, we investigate the fundamental principles for how sperm aster size is determined during growth and centration. By physically manipulating egg size, we obtain samples of eggs displaying a wide range of diameters, all of which are at identical developmental stages. Using live-cell and fluorescence microscopy, we find strong preliminary evidence that aster diameter and migration rates show a direct, linear scaling to cell diameter. Finally, we hypothesize that a collective growth model for aster growth, or centrosome independent MT nucleation, may explain how the sperm aster of large sea urchin zygotes overcomes the proposed physical limitations of a pushing mechanism during large aster positioning. By applying two methods of super resolution microscopy, we find support for this collective growth model in the form of MT branching. Together, we present a model in which growth of astral MTs, potentially through a collective growth model, pushes the sperm aster to the zygote center
