Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

Shortening chromosomes cause for earlier cancer onset in families with Li-Fraumeni syndrome

In families with a high incidence of Li-Fraumeni syndrome, the ends of individuals' chromosomes act somewhat like a lit fuse, according to researchers at The Hospital for Sick Children in Toronto. Their findings detail how telomeres, the ends of the chromosomes, shorten with every successive generation, leading to more severe cancers at an earlier age.

Researchers discover master switch for a tumor suppressive network

A decades-old cancer mystery has been solved by researchers at Cold Spring Harbor Laboratory (CSHL). "We not only found a critical tumor suppressor gene, but have revealed a master switch for a tumor suppressive network that means more targeted and effective cancer therapy in the future," said CSHL Associate Professor Alea Mills, Ph.D.

Horse genome sequence assembled

The first draft of the horse genome sequence has been deposited in public databases and is freely available for use by biomedical and veterinary researchers around the globe, leaders of the international Horse Genome Sequencing Project announced today.

Scientists step closer to understanding the relationship between aging and cancer

Wielding a palette of chromosome paints, scientists at the Salk Institute for Biological Studies have taken a step closer to understanding the relationship between aging and cancer by visualizing chromosomes of cells from patients with a heritable premature aging disease known as Werner Syndrome.

Gene found for Cornelia deLange syndrome

Studying mutations that give rise to a rare genetic disease, genetics researchers have identified a novel biological pathway that may have a broader role during human development, potentially in cases of mental retardation and autism.

RNA used to turn on genes to alleviate disease

A new technique that employs RNA, a tiny chemical cousin of DNA, to turn on genes could lead to therapeutics for conditions in which nudging a gene awake would help alleviate disease, researchers at UT Southwestern Medical Center say.

Men with short telomeres may have a greater risk for heart disease

Men with short telomeres - repetitive strips of DNA that cap the ends of chromosomes - may have a higher risk of developing coronary heart disease than those with long telomeres, according to an Article in this week's issue of The Lancet.

Specific gene found that protects some people with diabetes from severe kidney failure

A research team at Wake Forest University Baptist Medical Center and the University of Heidelberg has proven that a gene protects some people with diabetes from developing severe kidney failure or "end-stage renal disease."

Men who father only daughters have a higher risk of prostate cancer

In a new and unique study to determine if genes on the Y chromosome are involved in prostate cancer, researchers at Columbia University's Mailman School of Public Health in conjunction with Hebrew University of Jerusalem found that men who had only daughters had a higher risk of prostate cancer than men who had at least one son, thus signifying a possible defect on the father's Y chromosome.

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.

Scientists identify gene called HTRA1 that contributes to a major risk of Age Related Macular Degeneration

Researchers at the John A. Moran Eye Center at the University of Utah have identified a gene called HTRA1 that contributes to a major risk of Age Related Macular Degeneration (AMD), the most common cause of irreversible vision loss in the developed world.

Blood clotting protein appears to also play a role in fertility

A protein known to play a role in blood clotting and other cell functions is also critical for proper sperm formation in mice, according to researchers from the University of North Carolina at Chapel Hill School of Medicine.

SUMO1 gene implicated in cleft lip and palate defects

Researchers supported by the National Institutes of Health report in the current issue of the journal Science that a much-studied gene called SUMO1, when under expressed, can cause cleft lip and palate, one of the world's most common birth defects.

New target for cancer therapy identified by Australian researchers

A new target for cancer therapy has been identified by Monash University scientists investigating the cell signalling pathways that turn on a gene involved in cancer development.

HIV needs human protein - potential therapy target

Mayo Clinic virologists have discovered that a specific human protein is essential for HIV to integrate into the human genome.

Researchers identify genetic risk for type 1 diabetes

A discovery at the Barbara Davis Center for Childhood Diabetes has identified a genetic risk for type 1 diabetes three to four times higher than previously thought possible.

Prenatal diagnostic tests have low risk of miscarriage

Pregnant women who seek prenatal diagnostic testing to identify genetic or chromosomal abnormalities have a lower risk of miscarriage than previously believed, according to a UCSF study.

Variation in 3 genes influences risk of age-related macular degeneration

Researchers in Boston have discovered a new common, noncoding variant in the Complement Factor H (CFH) gene that is associated with age-related macular degeneration (AMD), the leading cause of irreversible visual impairment and blindness among persons aged 60 and older.
