Microtubules, part of heart muscle cells' internal "skeleton," help determine how the heart changes shape under stress, and a ...

Cortical microtubules are often, but not always, parallel to the cellulose microfibrils in the cell wall: the alignment of microfibrils helps to regulate the direction in which the cell can expand.

A new study by researchers from Drexel University College of Medicine reverses the popular scientific dogma that the protein tau stabilizes microtubules within brain cells. The scientists’ new ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling ...

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, ...

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 ...

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 ...

Though it is widely believed that tau protein stabilizes microtubules in neurons of the brain, new research suggests just the opposite: tau lengthens microtubules and keeps them dynamic. A new study ...

A review and update of a controversial 20-year-old theory of consciousness published in Physics of Life Reviews claims that consciousness derives from deeper level, finer scale activities inside brain ...

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 ...
