The microtubule inhibitor colcemid inhibited protein synthesis rapidly and at relevant concentrations, but vinblastine did not inhibit protein synthesis. Tubulozole T and colcemid inhibited protein synthesis posttranscriptionally since they had little effect on RNA synthesis.

1971-09-01 · The data suggest that microtubule proteins, at least in logarithmically growing cells, are not stored in a cytoplasmic pool but are synthesized in the same cell cycle in which they are assembled into oral structures.

Specifically, PAB inhibits microtubule polymerization and has the capacity to circumvent multidrug resistance (6, 7). Development of PAB as an anticancer drug is limited by supply, which depends on its isolation from golden larch roots or may be achieved through multistep chemical synthesis (5, 9). To further the knowledge of microtubule synthesis and inheritance during T. brucei cell cycle, the dynamics of the microtubule cytoskeleton was visualized by inducible YFP-α-tubulin expression. During new flagellum/flagellum attachment zone (FAZ) biogenesis and cell growth, YFP- α -tubulin was incorporated mainly between the old and new flagellum/FAZ complexes. The half life of a microtubule during mitosis is about 15 minutes, compared to 30 minutes during interphase.

Our series of 33 novel compounds contain the C The cortical microtubule array provides spatial information to the cellulose-synthesizing machinery within the plasma membrane of elongating cells. Until now data indicated that information is transferred from organized cortical microtubules to the cellulose-synthesizing complex, which results in the deposition of ordered cellulosic walls. Synthesis occurred almost exclusively in the G2 phase of the cloned aneuploid V79 line, whereas in the diploid Don line, considerable microtubule protein was synthesized in mid S phase as well as G2. The invention is directed toward measuring microtubule polymer stability in cells and tissues of the brain by measuring the molecular flux rates of microtubule synthesis and degradation (microtubule dynamics). The first orthogonal combinatorial synthesis of a high-purity triazine library was demonstrated. Novel triazine-based microtubule inhibitors were discovered by an efficient zebrafish embryo screening and in vitro microtubule polymerization assay.

To form cilia or flagella, microtubules arrange themselves in a "9 + 2" array. Each of the two central microtubules consists of a single microtubule with 13 protofilaments arranged to form the wall of a circular tube.

These herbicides are mitotic poisons that inhibit cell division. Gene ontology (GO) analyses indicated that processes related to microtubules are particularly sensitive to eEF2K inhibition. Our findings suggest that eEF2K likely contributes to neuronal function by regulating the synthesis of microtubule-related proteins. 2021-03-09 2011-03-17 Experiments with hepatocytes indicate that not only synthesis but the stability of tubulin protein was also regulated to maintain a specific level of tubulin.

Genetic regulatory mechanisms in the synthesis of microtubule dynamics in mitosis. Microtubules Microtubules are composed of 13 protofilaments They are nucleated at microtubule organizing centers (centrosomes in animal cells) Equilibrium mitochondrial dysfunction, water ordering, microtubule oscillations, disturbed AND EXTRACELLULAR MATRIX REGULATE DNA SYNTHESIS THROUGH Nucleation is the event that initiates the formation of microtubules from the tubulin dimer. Microtubules are typically nucleated and organized by organelles called microtubule-organizing centres (MTOCs). Contained within the MTOC is another type of tubulin, γ-tubulin, which is distinct from the α- and β-subunits of the microtubules themselves. Several proteins, including microtubule proteins, have been isolated from the oral apparatus of the ciliate Tetrahymena.
