The recombination of chromosomes: a controlled game of love and chance?
Sexual reproduction has many advantages - some most pleasurable - and probably leads to the long-term survival of the species concerned. During the formation of reproductive cells or gametes, sexual reproduction is accompanied by an exchange of genes between the two chromosomes inherited from the parents. Each individual arising from these gametes... view more... (2002-10-22)
Feinstein researchers develop new genetic method and identify novel genes for schizophrenia
Scientists at the Zucker Hillside Hospital campus of the Feinstein Institute for Medical Research have identified nine genetic markers that can increase a person's risk for schizophrenia. view more (2007-12-04)
Protein plays unexpected role protecting chromosome tips
A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell. view more (2009-08-14)
Discredited Korean embryonic stem cells' true origins revealed
A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells. view more (2007-08-03)
Newly-discovered mechanism can explain the Beckwith-Wiedemann syndrome
Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome. view more (2008-10-27)
Speeding the search for elusive chromosomal errors
A pediatric research team has used commercially available gene chips to scrutinize all of a patient's chromosomes to identify small defects that cause genetic diseases. view more (2006-06-13)
Geneticists tell ostrich farmers the secrets of sex
Research published in the online journal, BMC Biotechnology reports on a new, large-scale technique for distinguishing between male and female ostrich chicks using DNA extracted from feathers. This new technique will remove the need for invasive procedures currently in use to sex-type ostriches and allow breeders to discover the sex of their... view more... (2002-10-16)
Caesar researchers discover a mechanism in the pathogenesis of breast cancer
New approaches in breast cancer therapy view more (2005-05-17)
Study identifies molecular process underlying leukemia
New research from the University of North Carolina at Chapel Hill has identified a molecular process in cells that is crucial to the development of two common leukemias. view more (2006-08-22)
Little known DNA repair enzyme may be a tumor suppressor gene
The DNA in our cells is constantly being bombarded by environmental, chemical and cellular insults. Fortunately, our cells contain many enzymes devoted strictly to detecting and repairing any damage caused by these insults. view more (2006-01-04)
Researchers uncover potential mechanisms to protect against genetic alterations, diseases
Peering into the DNA of tiny yeast, researchers at the Moores Cancer Center at the University of California, San Diego and the San Diego Branch of the Ludwig Institute for Cancer Research have pinpointed a large number of genes that can prevent a type of genetic rearrangement that may lead to cancer and other diseases. view more (2009-08-07)
NYU biologists identify gene that coordinates two cellular processes
A team of biologists at New York University's Center for Comparative Functional Genomics has uncovered a dual role for the gene mel-28. The gene plays a part in ensuring that chromosomes are divided properly during cell division and it is required for nuclear envelope function. view more (2006-09-06)
Human clones could be ticking time bombs, warns ethics expert
Lausanne, Switzerland: Cloning of adults or children for reproductive reasons should be ruled out completely until researchers have discovered ways of counter-acting the health risks associated with the procedure, an expert on the ethics of cloning said today (Wednesday 4 July). Dr Guido de Wert, a senior research fellow in Biomedical Ethics from... view more... (2001-07-04)
Physician-Scientists Seek Solutions to Reproductive Problems Related to Chromosomal Variations
Approximately one in every 500 to 650 baby boys is born with an extra X chromosome, a variation in their genetic code that until a few years ago was thought to result in infertility in all cases. view more (2007-12-20)
New hope for regenerative medicine
In the February 15th issue of G&D, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. view more (2007-02-15)
Prenatal biochemical screening only detects half of chromosomal abnormalities
Prenatal biochemical screening tests are widely used to look for chromosomal abnormalities in the fetus which can lead to serious handicap, or even death during gestation or in the first few days after birth. view more (2008-06-02)
U-M researchers discover new genes that fuse in cancer
Using new technologies that make it easier to sequence the human genome, researchers at the University of Michigan Comprehensive Cancer Center have identified a series of genes that become fused when their chromosomes trade places with each other. view more (2009-01-12)
Bread mold may hold secret to eliminating disease-causing genes
When most people discover mold on their bread, they immediately throw it out. Others see a world of possibilities in the tiny fungus. A University of Missouri scientist, along with a collaborative research team, has examined a new mechanism in the reproductive cycle of a certain species of mold. view more (2008-05-09)
Scientists identify possible cause of endometriosis
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women affected by the condition. view more (2008-08-06)
Mapping dynamic Polycomb group proteins during Drosophila development
The developmental passage from a ball of cells to a fruit-fly is a very complicated process involving both temporal and spatial regulation of genes and pathways. view more (2006-04-20)
