Physicist cracks women's random but always lucky choice of X chromosome
A University of Warwick physicist has uncovered how female cells are able to choose randomly between their two X chromosomes and why that choice is always lucky. view more (2007-06-13)
How chromosomes meet in the dark -- Switch that turns on X chromosome matchmaking
A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development. Their discovery could also provide new insights into how other similar chromosomes spontaneously recognize each other and are bound together at key parts of... view more... (2008-12-29)
Scientists uncover mode of action of enzyme linked with several types of cancer
Scientists at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal have discovered a key mechanism used by cells to efficiently distribute chromosomes to new cells during cell multiplication. view more (2009-06-04)
Rong Li Lab probes mechanism of asymmetry in meiotic cell division
The Stowers Institute's Rong Li Lab has characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes. By tracking chromosome movement in live mouse oocytes, the team discovered that chromosomes can recruit to their vicinity a protein called formin-2. view more (2008-10-08)
Sex talk revelations of the lonely Y chromosome
In the week that the University of Leicester celebrates the 25th anniversary of the discovery of DNA fingerprinting new findings from the world-renowned University of Leicester Department of Genetics reveal for the first time that the male and female do truly communicate -at least at the fundamental genetic level. view more (2009-09-11)
Essential genes cluster clue to order in the genome
The identification of a cluster of essential genes on mouse chromosome 11 as well as similar clusters on the chromosomes of other organisms - including humans - buttresses the argument that there may be rules as to how genes are structured or laid out on chromosomes. view more (2007-05-04)
Chromosome glue repairs damaged DNA
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired. Now researchers at the Swedish medical university Karolinska Institutet have discovered a new mechanism that helps to explain how the cell performs these repairs. The results are presented in Science. view more (2007-07-16)
Researchers identify new drug targets for cancer
Solving a 100-year-old genetic puzzle, researchers at the University of California, San Diego (UCSD) School of Medicine have determined that the same genetic mechanism that drives tumor growth can also act as a tumor suppressor. view more (2007-01-02)
Slicing chromosomes leads to new insights into cell division
By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division. view more (2009-06-01)
A unique arrangement for egg cell division
Which genes are passed on from mother to child is decided very early on during the maturation of the egg cell in the ovary. view more (2007-08-10)
New Understanding Of Role Of Breast Cancer Gene In Normal Function And Disease
Researchers at the Medical Research Council (MRC) Cancer Cell Unit, Cambridge have gained an important new insight into the role of the breast cancer gene known as BRCA2. It appears to have a key function in cell division which needs to happen accurately for normal cell reproduction and repair, otherwise disease occurs. The findings are published... view more...

UGA researchers propose model for disorders caused by improper transmission of chromosomes
Parents of healthy newborns often remark on the miracle of life. The joining of egg and sperm to create such delightful creatures can seem dazzlingly beautiful if the chromosome information from each parent has been translated properly into the embryo and newborn. view more (2009-08-17)
Cell survival depends on chromosome integrity
As part of a large National Institutes of Health-funded Technology Centers for Networks and Pathways project, Johns Hopkins researchers have discovered protein machinery important for cells to keep chromosomes intact. view more (2006-07-10)
Evolution and the workaround
Living things are resourceful, which is a comforting thought unless the living thing in question is a pathogen or a cancer cell. Noxious cells excel at developing drug resistance, outwitting immune systems, and evading cellular controls. view more (2006-12-11)
A rainbow of methods promises insights into biological processes and diseases
Physical alterations of DNA in chromosomes can cause serious diseases such as Down syndrome, Prader-Willi syndrome, or cancer. view more (2007-05-02)
Oncologists could gain therapeutic advantage by targeting telomere protein
Inactivating a protein called mammalian Rad9 could make cancer cells easier to kill with ionizing radiation, according to research at Washington University School of Medicine in St. Louis. view more (2006-02-17)
The Advanced Age of the Father May Be a Risk Factor in Anomalies of the Foetus
A team of researchers at the Universitat Autònoma de Barcelona, co-ordinated by Professors Josep Egozcue and Cristina Templado, has shown for the first time that the older a man is, the more probable it is that his spermatozoa will present chromosome anomalies. This is the first time that a lineal relationship has been established with... view more... (2002-02-27)
When you've doubled your genes, what's 1 chromosome more or less?
An individual with Down syndrome and a male calico cat have one thing in common-each has an extra chromosome. For animals, most instances of an extra chromosome result in birth defects or even death, but plants are another matter entirely. view more (2009-09-15)
Chromosomes dance and pair up on the nuclear membrane
Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. view more (2009-11-16)
Duke-NIEHS team shows how DNA repairs may reshape the genome
Researchers at Duke University Medical Center and at the National Institute of Environmental Health Sciences (NIEHS) have shown how broken sections of chromosomes can recombine to change genomes and spawn new species. view more (2008-08-14)
