Cytoplasmic tubular filaments made from the protein tubulin. Microtubules contribute to the cytoskeleton and assist in the movements of organelles within the cell.

The microtubules were depolymerized and microtubule extensions became rather short (Fig.

The N-terminal area of the tau protein is a projection domain, which may determine the distance between microtubules in the axon and leads to axon diameter increase.
For their research, the scientists extracted microtubules from the brain tissue of cows, and mixed them kinesin - a protein that attaches to the microtubules - and adenosine triphosphate (ATP) - often called the "molecular unit of currency" of intracellular energy transfer.
In conclusion, this study demonstrates that GGD has cardioprotective activities against TAC-induced heart failure; these therapeutic effects might correlate with modulation of PTMs on microtubules. Our study provides experimental evidences for the application of GGD in the treatment of heart failure.
[32] showed that chlorpromazine did not induce obvious cell shape changes in astrocyte cultures but it clearly changed the distribution of Cx43, and this distribution was based on changes in the state of microtubules and microfilament.
Microtubules are an extremely important component of the cytoskeleton and are involved in cell division, vesicle transport, cell support, growth and development (Howard and Hyman, 2003; Struk and Dhonukshe, 2014).
Microtubules, which consist of heterodimers of [alpha]- and [beta]-tubulin, form the filamentous cytoskeleton of eukaryotic cells.
A number of landmark studies involving either physical or pharmacological manipulation of echinoderm eggs established the ability of the microtubules of the mitotic apparatus to specify the cleavage plane (reviewed in Rappaport, 1996; Burgess and Chang, 2005).
(2) Secondary wall patterns are formed by localized deposition of cellulose microfibrils, which results from guided movement of the cellulose synthase complex in the plasma membrane by cortical microtubules. (37) Cortical microtubules also act at the delivery of trans-Golgi network vesicles to the plasma membrane that deliver cellulose synthase complexes to cell wall deposition locales.
