New key mechanism in cell division discovered
Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have identified the mechanism by which protein Zds1 regulates a key function in mitosis, the process that occurs immediately before cell division. The ...

Slicing mitotic spindle with lasers, nanosurgeons unravel old pole-to-pole theory
The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering ...

Defect in transport system causes DNA chaos in red blood cells
Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation ...

Prion proteins play powerful role in survival, evolution of wild yeast strains
Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and ...

How old yeast cells send off their daughter cells without the baggage of old age
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. ...

Chromosome centromeres are inherited epigenetically
Centromeres are specialised regions of the genome, which can be identified under the microscope as the primary constriction in X-shaped chromosomes. The cell skeleton, which distributes the chromosomes to ...

Research team clarifies mechanics of first new cell cycle to be described in more than 20 years
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 ...

Do bacteria age? Biologists discover the answer follows simple economics
When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria. ...

Study reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...

How bookmarking genes pre-cell division hastens their subsequent reactivation
In order for cells of different types to maintain their identities even after repeated rounds of cell division, each cell must "remember" which genes were active before division and pass along that memory to its daughter ...

Study finds protein critical to breast cancer cell proliferation, migration
Researchers have found that a protein linked to cell division and migration and tied to increased cell proliferation in ovarian tumors is also present at high levels in breast cancer specimens and cell lines. The protein, ...
