Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals. The discovery was made by applying the latest laboratory methods to a strain of mice restored from embryos frozen since the early 70s.

Genome research sheds light on Bardet-Biedl syndrome

By comparing the genomes of an alga, a weed and humans, a team of researchers has identified a new gene behind Bardet-Biedl syndrome (BBS), a complex condition marked by learning disabilities, vision loss and obesity.

Scientists believe that the dog genome holds a wealth of information that will benefit human health

Recently completed genetic analysis reveals that half of the more than 300 inherited canine disorders — including a number of cancers — resemble specific diseases of man; many scientists believe that the dog genome holds a wealth of information that will benefit human health.

Cell division can be halted in multiple ways, with implications for cancer

Brown University researchers have found that there are multiple independent ways to stop cell division, a phenomenon that prevents the spread of genetic mutation, which can make cells cancerous. Results of this research, along with an accompanying editorial, were published in the current issue of the journal Molecular Cell.

National Cancer Institute (NCI) purchases Starbridge Hypercomputer® to accelerate genome data research

Starbridge Systems announced today that the National Cancer Institute's Advanced Biomedical Computing Center (ABCC) in Frederick, MD, recently purchased a Starbridge Hypercomputer®, the first high-end reconfigurable computer acquired for bioscience research.

Discovery of the gene for Cornelia de Lange syndrome

An international team of researchers has discovered the gene for Cornelia de Lange syndrome, a disabling, multisystem genetic disease that affects an estimated one in 10,000 children. The finding is expected to lead to a genetic test, enabling rapid and definitive diagnosis of the syndrome, as well as prenatal testing for families who already have one child with the disease.

Want a new type of man? Maybe less brawn and more brains?

A new version of the human male is a distinct possibility, given the genetic erosion of the “junk” sex-determining chromosome that makes men male.

Chromosome losses can signal an especially poor response to therapy

A new international study of children with a severe form of acute lymphoblastic leukemia(ALL) shows that certain chromosome losses can signal an especially poor response to therapy, but that other chromosome abnormalities have no effect on treatment survival.

Father's sperm packs more than just a fertilizer

The major function of a man's sperm was fertilization, scientists once thought. True, sperm contains the father's chromosomes; but new studies from Wayne State University show that RNAs critically important to early growth of an embryo are also delivered.

New way by which cells can become cancerous may solve mystery with lung cancer

Researchers at The University of Texas M. D. Anderson Cancer Center are describing an entirely new way by which cells can become cancerous. And they say their finding provides an answer to a mystery in lung and other cancers.

Researchers find an entirely new way by which cells can become cancerous

Finding provides an answer to a mystery in lung and other cancers: why a potent tumor suppressor gene called FUS1 functions as it should, yet none of the protein it produces can be found anywhere in a cancer cell.

Research uncovers critical pieces of human genome

Researchers have found precisely the same sequences in the genomes of humans, rats, and mice; sequences that are 95 to 99 percent identical to these can be found in the chicken and dog genomes, as well.

Study sheds new light on children with a severe form of acute lymphoblastic leukemia

A new international study of children with a severe form of acute lymphoblastic leukemia (ALL) shows that certain chromosome losses can signal an especially poor response to therapy, but that other chromosome abnormalities have no effect on treatment survival.

Developing smart drugs

Dana-Farber Cancer Institute Researchers, sensing an opening in the cancer battle, are mounting a quick thrust to flush out suspected molecular cancer triggers in tumor cells.

Scientists have discovered a genetic cause of cleft lip and palate in mice

By watching mice “dance” and comparing the DNA of the dancers to their flat-footed siblings, scientists have discovered a genetic cause of cleft lip and palate in mice, a finding that is already being used to search for a similar genetic defect in humans.

Transplanted bone-marrow cells could regenerate nerve cells in the brain

Findings of a preliminary study in this week's issue of THE LANCET suggest that transplanted adult bone-marrow cells could regenerate nerve cells in the brains of human stem-cell recipients. These early findings, if confirmed in future research, have implications for the treatment of neurodegenerative disorders such as Parkinson's disease.

Mystery surrounding ageing, death and cancer is dispelled by new study

Scientists from Cancer Research UK and Breast Cancer Campaign have uncovered the first evidence of an entirely new system for holding the ravages of time at bay.

Lou Gehrig’s disease gene discovered

A gene for a rare juvenile-onset form of amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) has been isolated in families in the United States, Belgium and Austria, the Muscular Dystrophy Association (MDA) announced today.

Clinical trial of enzyme replacement therapy for the treatment of Gaucher disease

Transkaryotic Therapies, Inc. today announced that it has initiated a clinical trial to evaluate the safety and clinical activity of GA-GCB, its enzyme replacement therapy for the treatment of Gaucher disease.

Discovery shows how single genetic mutation can cause complex disorders

Bardet-Biedl syndrome (BBS), characterized by obesity, learning disabilities and eye and kidney problems, is caused by genetic mutations in the BBS family of genes. Now, researchers who've long studied the condition have discovered that genetic mutations in one of those genes, called BBS4, lead to cell death by disrupting the cells' internal "highway" system.
