Protein 'comet tails' propel cell recycling process

Several well-known neurodegenerative diseases, such as Lou Gehrig's (ALS), Parkinson's, Alzheimer's, and Huntington's disease, all result in part from a defect in autophagy - one way a cell removes and recycles misfolded ...

Study yields insights into how plant cells grow

A study by Purdue University plant scientists and University of Nebraska-Lincoln engineers advances our understanding of how plants control their shape and development at the cellular level.

Unlocking long-hidden mechanisms of plant cell division

Along with copying and splitting DNA during division, cells must have a way to break safely into two viable daughter cells, a process called cytokinesis. But the molecular basis of how plant cells accomplish this without ...

Researchers uncover secrets of internal cell fine-tuning

New research from scientists at the University of Kent has shown for the first time how the structures inside cells are regulated – a breakthrough that could have a major impact on cancer therapy development.

Atomic structure of key muscle component revealed

Actin is the most abundant protein in the body, and when you look more closely at its fundamental role in life, it's easy to see why. It is the basis of most movement in the body, and all cells and components within them ...

Researchers develop new model of cellular movement

(Phys.org) —Cell movement plays an important role in a host of biological functions from embryonic development to repairing wounded tissue. It also enables cancer cells to break free from their sites of origin and migrate ...

Cytoskeletons get a closer look

(Phys.org) —Rice University researchers have developed a theoretical approach to analyze the process by which protein building blocks form the biopolymer skeletons of living cells.
