Adult stem cells activated in mammalian brain
Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a study by UC Irvine scientists has shown.   view more (2008-07-25)

New techniques in plant chloroplast division hold hope for agriculture
Ground-breaking research at the University of Leicester into the division of chloroplasts holds out hope of a safer way of genetically modifying crops, with implications for agriculture particularly in the developing world. Using three plant types - Arabidopsis, tomato and rice - Dr Simon Geir M'¸ller has been working with colleagues in the... view more... (2003-01-20)

Key to 'curing' obesity may lie in worms that destroy their own fat: McGill researchers
A previously unknown mutation discovered in a common roundworm holds the promise of new treatments for obesity in humans, McGill University researchers say.   view more (2008-12-09)

Checkered history of mother and daughter cells explains cell cycle differences
When mother and daughter cells are created each time a cell divides, they are not exactly alike. They have the same set of genes, but differ in the way they regulate them.   view more (2009-10-20)

Math model accurately mimics cell division in carbon-cycling bacterium
Scientists from the Department of Biological Sciences and the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a quantitative, mathematical model of DNA replication and cell division for the bacterium Caulobacter crescentus.   view more (2009-08-14)

Normal chromosome ends elicit a limited DNA damage response
Researchers at the Salk Institute for Biological Studies discovered that cells co-opted the machinery that usually repairs broken strands of DNA to protect the integrity of chromosomes.   view more (2005-11-28)

Outsmarting cancer - new results from novel enzyme inhibitors
Smart drugs that can break the chain of command between enzymes and the genes involved in cell division and cell death are a new way forward in tackling breast cancer, according to Dr Stephen Johnston, a consultant oncologist from The Royal Marsden Hospital, London, UK. He was speaking at a news briefing on Thursday (21 March) at the 3rd European... view more... (2002-03-19)

Researchers examine mechanisms that help cancer cells proliferate
A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.   view more (2009-09-02)

Sugar helps control cell division
Johns Hopkins scientists have discovered that a deceptively simple sugar is in fact a critical regulator of cells' natural life cycle.   view more (2005-09-22)

CSHL scientists discover link between control of chromosome duplication and segregation
Before a cell can divide into two, first it must duplicate its genetic material--the DNA packed in its chromosomes. The two new sets of chromosomes then have to be separated from one another and correctly distributed to the resulting "daughter" cells, so that both daughter cells are genetically identical to the original, or... view more...

Algae provide new clues to cancer
A microscopic green alga helped scientists at the Salk Institute for Biological Studies identify a novel function for the retinoblastoma protein (RB), which is known for its role as a tumor suppressor in mammalian cells.   view more (2006-10-13)

Dividing cells 'feel' their way out of warp
Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs - even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes.   view more (2009-09-11)

Possible evidence of cell division, differentiation found in oldest known embryo fossils
A group of 15 scientists from five countries has discovered evidence of cell differentiation in fossil embryos that are more than 550 million years old.   view more (2006-10-13)

Link unraveled between chromosomal instability and centrosome defects in cancer cells
In a new study, Dana-Farber Cancer Institute scientists disprove a century-old theory about why cancer cells often have too many or too few chromosomes, and show that the actual reason may hold the key to a novel approach to cancer therapy.   view more (2009-06-08)

Tumor suppressor gene in flies may provide insights for human brain tumors
In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor.   view more (2009-06-23)

A tiny pinch from a 'z-ring' helps bacteria cells divide
In process that is shrouded in mystery, rod-shaped bacteria reproduce by splitting themselves in two. By applying advanced mathematics to laboratory data, a team led by Johns Hopkins researchers has solved a small but important part of this reproductive puzzle.   view more (2007-10-12)

CHECKING HOW CELLS GROW: New research dismisses a widely held assumption about cell growth
Research published today in Journal of Biology challenges an assumption about cell growth that underpins modern cellular biology. Ian Conlon and Martin Raff, of University College London, show that mammalian cells do not regulate their size in the way scientists have assumed they do since the 1970s. Conlon and Raff conducted a series of... view more... (2003-04-23)

Possible New Cure for Psoriasis
Cell biologists of the University of Bonn, in cooperation with the University of Leeds (U.K.) and industry may have discovered a new effective therapy for psoriasis: a specific group of what are known as metalloproteinase inhibitors can normalise the increased tendency of epidermis cells (keratinocytes) to divide, which is the cause of this... view more...

Rat kidneys and toad brains communicate in almost the same manner
Dutch researcher Niels Cornelisse used computer models to study the electrochemical communication between cells from rat kidneys and cells from the pituitary gland of a toad species. He found many similarities in the coupling of chemical and electrical signals in these completely different cells.   view more (2004-05-07)

Researchers use chemical from medicinal plants to fight HIV
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised.   view more (2008-11-10)
