Inside cells, microtubules not only serve as a component of the cytoskeleton (cell skeleton) but also play a role in intracellular transport. In intracellular transport, microtubules act as rails for ...

Microtubules are active protein polymers critical to the structure and function of cells and the process of cell division. In a living cell their growing ends constantly elongate and retreat in a ...

Cellular life hinges on a network of hollow cables called microtubules dynamically lengthening and shortening according to the needs of the moment. During cell division, for instance, these cables ...

Microtubules exist in every eukaryotic cell. The striking sequence conservation of tubulins throughout evolution is reflected by their near identical structure across virtually every species in which ...

Microtubules help to regulate cell structure throughout our bodies. A group of researchers have used cryo-electron microscopy to shed light on how a certain protein keeps microtubules stable, and ...

Almost all cell types exhibit some form of polarity; cell polarity refers to the spatial differences in shape, structure and function within a cell, which enables the cell to carry out specialized ...

Microtubules—cellular "highways" that deliver cargo to the cell membrane for secretion—have a surprising role in pancreatic beta cells. Instead of facilitating glucose-stimulated insulin secretion, ...

The chromosomes, once they have duplicated genetic information, move to the center of the cell and the cell, in a very remarkable way, quickly sprouts from its two ends large tubes that hook the ...

Microtubules are hollow biopolymers of 25-nm diameter and are key constituents of the cytoskeleton. In neurons, microtubules are organized differently between axons and dendrites, but their precise ...

Microtubules are cell constituents that display several astounding properties and a unique pattern of behavior during the cell cycle. Microtubules are regulated by several proteins and complexes, and ...

A joint research team from the LKS Faculty of Medicine (HKUMed) and the Faculty of Science at the University of Hong Kong has uncovered an unexpected interaction between chemotherapeutic agents and a ...

Direct evidence that microtubules function as mechano-sensors and regulate the intracellular transport of molecules has been reported, leading to new possibilities in the fields of biomechanics, ...
