Secrets of chromosome movement revealed

Investigators at St. Jude Children's Research Hospital have used the lowly yeast to gain insights into how a dividing human cell ensures that an identical set of chromosomes gets passed on to each new daughter cell.

Researchers shed light on shrinking of chromosomes

A human cell contains an enormous 1.8 metres of DNA partitioned into 46 chromosomes.

Scientists work out mechanism underlying asymmetric cell division in nematode worms

When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells.

Important step towards a spatially and temporally quantifiable model of the cell

Cell membranes are like two-dimensional fluids whose molecules are distributed evenly through lateral diffusion.

Study suggests reason for high incidence of cancer in the prostate

Cancer occurs more frequently in the prostates of men than in any organ other than the skin. While DNA damage caused by exposure to the sun is likely the cause of many skin cancers, the cause of prostate cancer remains largely unknown.

Discovery of new cell involved with cancer

Scientists have discovered a new type of cell that appears to play a role in the development of cancer – a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.

Researchers discover a new mechanism that regulates stem cell division

Errors in stem cell division can give rise to tumours. By studying stem cells in the fruit fly, scientists at the Institute for Research in Biomedicine (IRB Barcelona) have identified one of the mechanisms that govern how these cells divide.

Unlocking the mystery of skin renewal

Everyday we shed the outermost layer of our skin and replace it from within with new skin cells. Scientists from Cambridge have looked at the way that skin is renewed.

Selective marker found to indicate aggressive form of breast cancer

Researchers have linked a structural protein called nestin to a particularly deadly form of breast cancer, identifying a new biomarker that could lead to earlier detection and better treatment.

New embryonic cell discovery

Cambridge scientists have discovered the stage at which some of the cells of a fertilised mammalian egg are fated to develop into stem cells and why this occurs.

Scientists discover function for antisense RNA

Researchers have found that a class of RNA molecules, previously thought to have no function, may in fact protect sex cells from self-destructing. These findings will be published in the November 17 issue of the journal Cell.

Evolution is driving therapeutic resistance to cancer therapies

The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams.

Stem cells contain immortal DNA

EuroStemCell scientists at the Pasteur Institute in Paris have demonstrated one of the body's most sophisticated ways of regulating the genetic material of stem cells.

Scientists discover molecular security mechanism for keeping gene mutations in check

Everyone knows mutations - genetic mistakes in DNA, the material of heredity - are bad: The more mutations in the cell's DNA, the higher the risk of cancer developing.

New understanding of chromosomal glue

Researchers have a new understanding of the process cells use to ensure that sperm and eggs begin life with exactly one copy of each chromosome - a process that must be exquisitely regulated to prevent problems such as miscarriages and mental retardation.

Researchers find genetic "signature" that accurately identifies colon cancer

Researchers at Jefferson Medical College in Philadelphia have uncovered a genetic "signature" that accurately identifies colon cancer--a key, they hope, to better understand how the cancer develops.

New discovery explains how a common gene variant may increase cancer risks

Roughly 15 percent of the population carries a gene variant that may increase the risk of developing cancer. The cause of this increased risk has been unknown until now. But now a research team at Stockholm University in Sweden can explain why.

New research has implications for treating muscular dystrophy

In a surprising discovery with implications for treating muscular dystrophy, researchers at the University of Utah School of Medicine and other institutions have identified a major source of origin for two groups of adult cells that regulate muscle repair.

DinB DNA polymerase is a key player in DNA repair

A quarter century after they discovered it, researchers have identified the job of one of the most common DNA-damage response proteins. The enzyme has puzzled scientists because it is present in nearly every organism, which suggests that it is crucial to life, and yet, in laboratory experiments, its function has remained a mystery.

Molecular mechanism involved with neural tube defects

Environmental and genetic factors lead to neural tube defects in 1 in every 1,000 births and cause 1 in 20 of every spontaneous abortion. One cause of these defects is the failure of cells within the neural tube to migrate to the middle of the developing neural tube.
