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.

New novel protein-genome interaction mapping technology

Fred Hutchinson Cancer Research Center, The Netherlands Cancer Institute (NKI) and Cancer Research Technology Limited (CRT) today have released details of the development and commercialisation of a powerful protein-genome interaction mapping technology termed 'DamID.'

Rett syndrome can also strike males

The common thinking in the past had been that Rett syndrome only affects girls.

Leukemia gene changes genetic packaging

A signaling system involved in many forms of leukemia and lymphoma is more powerful than scientists have thought, exerting control over our genes by affecting whole swaths of chromosomes in global fashion.

Gene family expansion can begin even before a gene is duplicated

Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve.

DNA of human embryonic stem cells is chemically modified in a characteristic, predictable pattern

Embryonic stem cells are derived from embryos that are undergoing a period of intense cellular activity, including the chemical addition of methyl groups to specific DNA sequences in a process known as DNA methylation.

Genomic expansion and diversification in a African sleeping sickness parasite allow it to evade host detection

A team of scientists headed by Dr. Sara Melville at the University of Cambridge has shown that the parasite known to cause African sleeping sickness has evolved an unusual chromosomal structure as a result of environmental adaptation.

Different genes may be responsible for causing autism in boys and girls

In the on-going search to find the cause of Autistic Spectrum Disorders, the latest research says different genes may be responsible for causing autism in boys than in girls, and the discovery may help explain why the condition is more common in boys.
