Latest Cell cycle Stories
The accumulation of damaged protein is a hallmark of aging that not even the humble baker's yeast can escape. Yet, aged yeast cells spawn off youthful daughter cells without any of the telltale protein clumps.
An international team of scientists, including biologists from the University of North Carolina at Chapel Hill, may have pinpointed for the first time the mechanism responsible for cell polyploidy, a state in which cells contain more than 2 paired sets of chromosomes.
An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.
In a technical tour de force, scientists at Fox Chase Cancer Center have cataloged and cross-indexed the actions of 178 candidate drugs capable of blocking the activity of one or more of 300 enzymes, including enzymes critical for cancer and other diseases.
Scientists at Dana-Farber Cancer Institute and Harvard Medical School have found that a common cancer protein leads a second, totally different life in normal adult brain cells: It helps regulates memory formation and may be implicated in Alzheimer's disease.
Researchers at the California Institute of Technology (Caltech) have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division.
Most cells rely on structural tethers to position chromosomes in preparation for cell division.
When an egg cell is being formed, the cellular machinery which separates chromosomes is extremely imprecise at fishing them out of the cell's interior.
Cells are the building blocks of the human body.
As any rock-climber knows, trailing a long length of rope behind you is not easy.
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
